Hi there. I'm an "Alekhiner" (may be a good neologism  Smiley)
from many years... I played very little in recent years but I am slowly reconnecting.
I'm writing some notes and analisys on one of my sites about our preferred defense. When they're ready i'd be glad to share with you, if you like, and hear your opinions.

one more curiosity:

on the 3rd round of the olympiad, the game 
Topalov - Mauricio Arias Santana (Elo about 2300)
finished  1- 0
it was a Kengis and apparently Black was quite well for
several moves (in fact, according to chessvibes, Black did an unecessary exchange sacrifice on move 44)

almost 500 ELO points separate the two players, so
I guess thiis game might be included in a chapter of
a future book, the chapter titled "when World champions have difficulties playing against the Alekhine"

Two curiosities:

i) Natalia Zhukova played consistently the Alekhine
(fianchetto lines and the Alburt) in the last World Blitz championship. Results are not astounding, but it is curious to see many of the lines here mentioned in the past, played by her.

ii) Today on the first day of the Olimpiad, Ivanchuk
played 1...Nf6 against 1.e4 which I think was a first since a long time ago; no doubt this was against a much weaker player; since he did contribute a lot to the defence we might hope to see more;
as a curiosity, White played 2.Nc3 and Ivanchuk played
(!!) 2...e5 and we got a Vienna. Since there has been a live discussion about the best way to reply against 2. Nc3 and since many books advocate not to play 2...d5, we could see Ivanchuk's move as an expert opinion on the matter.

I asked about the timeline (sorry for the mess in previous message since my text was embedded into yours) becausee I feel that this Voronezh article appears out oftime.
Previous Alekhine (and other openings) articles are motivated by a recent game. In fact, for this one has to congratulate NIC. What puzzle sme is that I was not aware that anything interesting (to make an article in NIC) has been played in this variation

If you send in a timely letter, you can pretty well count on it appearing in the next volume.

I think you have to be an IM or better to get an article published, though they have let in Martin-de-What's-His-Name a few times and maybe one or two other amateurs armed with a strong computer.  I'm not at all sure of the wisdom of that.  

In the latest issue someone tries to prove that that endgame that arises from the Two Knights with 4.d4 and ...Qa5 is a win for White.  Someone always tries to do that every ten years or so, and it isn't true.  I don't have it in my files any more, but Pal Benko took a long look at that ending in his excellent Chess Life column and concluded that if anything, Black has the better play for a win.

I wish I still had that piece.  Does anyone?

any idea what is the delay between submitting an article and it really appearing?

based on a few past ones, e.g., the last one on the Alburt by Van der Tak, I would say it is quite fast

Yeah, this came in the mail on Saturday, and the article looks like real crap to me.  Utterly incognizant of discussions and Watson's analyses here, for one thing, and not breaking any new ground that I could see.  Do these people get paid for this?  They should send back their paycheck.

tks,


The US Open games are available for dowload in TWIC:

The Nakamura game is in Megabase - An ...exd6 Exchange. White was better but missed a tactic - in the end, a draw. 

If there is sufficient interest I might post a file of Ramirez's Alekhine games at the Alekhine Defense Working group.


Thanks,
and probably yes

Seeking an Alekhine's defence role-model?

The young US-based GM Alejandro Ramirez from Costa Rica just won the 111th Annual U.S. Open ended at the Hyatt Regency in Irvine, California with a score of 8-1. See

http://main.uschess.org/content/view/10605/598

For Alekhine players looking for possible role models, Ramirez might be one to watch. He frequently plays our opening (so far I have 29 of his games in my database) and he scored two useful points with it at the US Open; this was admittedly against lower-rated opponents, but in the past Ramirez has shown that he is not afraid to play the Alekhine against GMs (Nakamura, Kritz, Becerra...).

I perhaps ought to add that Ramirez also plays a mean Sicilian - his US Open win against GM Khachiyan is a wonderful example of dynamic Sicilian play.

At 
http://www.chesscafe.com/abby/abby.htm
Abby Marshall provides a general survey of the Four Pawns attack. The same material is also available in pgn via the Chess Theatre link.

I have only scanned her article brielfy so far but first impression is that it is based on "official" theory rather than home analysis so it will probably be of little interest to Alekhine fanatics. Nevetheless, players new to the Alekhine might find this article a useful strating point.

well, since everybody is giving comments on Taylor's book, let me add a few:

i) I confess that most of the lines I like are not here but in any way this is a book I am glad to have

ii) it has many positive points, most of them related with how the author defends the lines he suggests,
eg, exchange, 4PA, 2.Nc3, etc.; 
although I would have
preferred a book on the exchange with cxd6 (why did
Marin skipped that on his articles on CBM?) it appears that Taylor makes a strong point for using exd6, even
as winning for Black. One interesting (missing) point is: in a game by Larsen with the bishop in g4,
Black moves to h5 after White playing h3 - in another game by Larsen played by much later (not even mentioned in the book), Larsen played Bxf3 and won (apparently this is the line recommended in several other books)

ii) one point I really dont like (here i strongly agree with Markovich) is in the way he argues against non recommended lines: i) when illustrating why Black should not play a certain line, he uses games that are
not the best from White's point of view misleading
a player  on what is best for White; for instance with respect to the Alburt, apparently it was more important to say that a player like Alburt (an expert on the Alekhine)  lost 4 games against Short rather than show games that really show Black's current troubles. By the way, was not Short at the time better than Alburt? And isnt an advantage to White to know that the Black player always plays the same opening?
ii) I dont agree with arguments like "I prefer this line since here we play chess; and in the other line we need to memorize several (computer) moves"; aren't computers, now, part of the preparating for this game? should we skip a line because it needs from us
several hours of preparation and several hours a week
(a month) of currently being updated? one example
was why he dismisses 5...Nd7 in the Larsen; as far as I remember Miroschnichenko made good use of this line several years ago (playing it continuously) and as far as I remember never lost unprepared againt the Nf7 sacrifice
iii) I am really not in favour of the argument "today I lost because your computer is better than mine".
I would prefer to say that "today I lost because MY analysis with the help of my computer/program was not good/deep enough".
In fact, Taylor's dismisses lines where apparently computers make it a lot easier to evaluate lines; here is one case he misses, in the Qf3 variation against the Larsen,
in the game shown, Black played Qd4+ and White answered with Nd2. What happens if White plays Bd2 leaving the Pawn on b2 undefended? This has been suggested by Burguess on his second book as leading
to a win for White. I think (with the help of computer/program) that the move leads to a draw, with best play from both sides. But the analysis is far from easy, the game does not fade to a draw in a few moves, and the engines really help us to analise
the variations starting with Bd2

Taylor's book is quite a good introductory guide, but I would recommend starting with Cox's book, which is more objective and in my view provides better explanation and examples of the key ideas in each variation of the Alekhine. If you are a thrifty chess player, you can use only Cox's book and update your theoretical knowledge using the threads on this Forum and the aforementioned Alekhine Working Group.
  

All our dreams come true if we have the courage to pursue them.

First, it is correct to say "This kind" not "These kind".
Second, what do you mean? Please explain! Smiley

Do you means all books on the Alekhine?

Do you mean repertoire books, in general?

For a chess player your attack is not very precise! Wink

I think I forgot the s after kind, but grammar don't matter, do it? Wink

To be more precise I was referring to repertoire books that cover sidelines of sidelines. A little tongue in cheek of course, but I certainly stand by the remark.
  

If nothing else works, a total pig-headed unwillingness to look facts in the face will see us through.

Agreed. Taylor's book would be very useful to someone starting out with the Alekhine and it does fill in some gaps in other works. However, most of the lines he goes to great lengths to tell us he doesn't like are, in fact, the main theoretical battlegrounds in the Alekhine, so his book won't be any help in understanding the lines discussed in this thread, for example.


Well, I gave some of views on Taylor's book already (above). Agreed, he can be a bit irritating and "in your face". Also (disappointingly) he gives the solid (tedious?) ...exd6 against the Exchange, but that is also in line with the preference of many current GMs e.g. Short, Spraggett, Mirzoev, Degraeve, Kraai, Narciso, Davies, so perhaps we should accept that that's the current trend among titled players, most of whom only have the Alekhine as an occasional weapon.

All I can say to summarise is that I (currently 2144 at age 62 - I give that information just for context) am glad to have Taylor's book. With over 80 Alekhine games played over the board, against players from 1800 up to the likes of Danny King and Mark Hebden, I have to say I found the book very readable, interesting and even refreshing.

Personally I do find the other side's repertoire books worth reading.

Taylor's book is useful, I suppose, but he puffs it up with a tremendous quantity of exposition of what he does not like.  I'm surprised that his editors permitted him to do so much of that.  If you trim the book to include only his exposition of his recommended lines, it would be, oh, perhaps two-thirds or one-half its actual length.

Taylor also persistently mocks  preferences alternative to his own, which I found neither convincing nor endearing.

Taylor gives you a repertoire, i.e. he chooses the lines for you to play, so yes that could be a useful "starter-pack" for playing around with the Alekhine. His choices are subjective of course, but mostly he explains them and he also shows you some lines he rejected and tells you why.

Cox or Bogdanov or Davies would give you a more objective overview and they cover more ground.

Burgess's two older books will also very useful if you find you are really getting to like this opening. I could on...Bagirov is still very useful for instance. Alekhine's defence tends to attract real devotees (fanatics?)! 

It probably helps if you've played quite a few other defences first, since Black's flexible pawn structure means that a variety of pawn structures can be reached, so if you don't know your way around them you can easily become lost.

Good luck!

I've attached some analysis of his game against M.Rich which shows that one of the ...d5 lines that I initially dismissed as bad for Black in fact seems to provide interesting compensation.

Today Tymrakiewicz has played an interesting sacrificial line first analysed at the forum's Alekhine offshoot, the Alekhine Defence Working Group! More on this later.

A big thankyou to Luis for drawing my attention to these games!


As promised, here (attached, with light notes) is today's game featuring 9...Bf5 against the Voronezh. It features a successful first (as far as we know) outing for a sacrifice proposed by Mark Morss and included in the Alekhine Defense Working Group's extensive survey of 9...Bf5.

Against an over-2200 opposition i would probably lose even with an extra queen, so that is not a problem Grin.
Returning to Paddy's line, probably my poor english is the reason of your misunderstanding;
My doubt was not about the line Quote:
9....Bf5 10.Nf3 Bg4
which looks very clever to me but about Quote:
9...Bf5 10 Be2 e5!?
and only now 11 Nf3 where 11...Bg4?! can't be followed by d5 because black has already played e5.
If fact my question is: if white avoids dxe5 and simply develops with Nf3 is black committed to a waiting move or there is an active plan that i am missing?


First, to clarify, after 1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. exd6 cxd6 5. c4 Nb6 6. Nc3 g6 7. Be3 Bg7 8. Rc1
O-O 9. b3 Bf5 10. Nf3 the idea is definitely to lose a tempo and play 10...Bg4, aiming to reach a normal type of position in which the d4 pawn is fixed, e.g.

[Event "North American op 17th"]
[Site "Las Vegas"]
[Date "2007.12.28"]
[Round "5"]
[White "Andrews, Todd D"]
[Black "Nakamura, Hikaru"]
[Result "0-1"]
[ECO "B03"]
[WhiteElo "2304"]
[BlackElo "2648"]
[PlyCount "70"]
[EventDate "2007.12.26"]
[EventType "swiss"]
[EventRounds "7"]
[EventCountry "USA"]
[Source "ChessBase"]
[SourceDate "2008.01.10"]

1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. exd6 cxd6 5. c4 Nb6 6. Nc3 g6 7. Be3 Bg7 8. Rc1
O-O 9. b3 Bf5 10. Nf3 Bg4 11. Be2 e6 12. O-O d5 13. c5 Nc8 14. b4 Bxf3 15. Bxf3
a6 16. a4 Nc6 17. b5 Na5 18. Re1 h6 19. Bf4 Ne7 20. Be5 Bxe5 21. Rxe5 Nf5 22.
Be2 axb5 23. axb5 Qf6 24. f4 Nxd4 25. Qxd4 Nb3 26. Qe3 d4 27. Ne4 Qxe5 28. Qf3
Qf5 29. g4 Qxe4 30. Qxe4 Nxc1 31. Bc4 d3 32. Qe3 Rfd8 33. Qd2 Ra4 34. Bxd3 Nxd3
35. c6 Ra1+ 0-1

Secondly, if White prevents ...d5 by playing 12 d5 himself, Black can reply with 12...e5, e.g.

[Event "FRA-chT Top 16 GpA"]

Of course, Black was eventually in difficulties in the Baklan game ("I swindled Vladimir Baklan with black in an Alekhine and drew." Nakamura) but that does not necessarily imply that Black was significantly worse in the opening. Although in most lines Black does indeed do best to adopt the ...d5. ...e6 pawn centre, there are many Alekhine games by strong players in which the ....d6, ...e5 centre provided enough counterplay and the structure of white pawns c4 and d5 vs black pawns d6 and e5 is a familiar one from the ...e5 Sicilian lines.

However, it is not clear to me why Nakamura did not play 11...d5 in the two games above; why is it necessary / better to prepare it with 11...e6? Unless White has something better than 12 c5 Nc8 13 0-0 it seems that the game is likely to transpose to

Thirdly, 10 Be2 e5!? is (as far as I know) a new position, so we can only be tentative at this stage. My previous posts argued that Black has sufficient counterplay if White exchanges the pawns and the queens and that Black is sufficiently better off than in the lines with 9...e5. If White declines to exchange on e5 and develops with 11 Nf3 instead, then Black has several plausible moves e.g. 11...e4 (this forcing move should be analysed first - if good, problem solved!), 11...Nc6, 11...Qe7 and maybe 11...Na6.

Fourthly, we need to work out how to develop after 10 Be2 e5!? 11 d5, when the bishop might be misplaced on f5. (Baklan-Nakamura may or may not indicate the way to go.)

Fifthly, I began to worry whether there was a simple positional refutation of 9...Bf5 in 10 d5, intending Nf3-d4 with the sort of bind/space advantage  - based on a pawn structure known to be favourable to White (e.g. from the Sicilian Dragon) - which is the main point of the Voronezh move order, but I think Black's counterplay comes quick enough despite another loss of tempo with the bishop (!)  i.e. 10 d5 e5! and if 11 dxe6 Bxe6 12 Nf3 Nc6 13 Be2 d5! and if then 14 c5 d4! seems at least =+.

Your thoughts please!


Only a blitz game, I know, but it is surely interesting to see how Nakamura responded when faced with his own 9...Bf5 line in the recent Dos Hermanas blitz competition.

By the way, GM Skembris is not convinced by the tactical 10...d5. He definitely prefers the strategical play after 10...e5 etc. Wink

Did GM Skembris have anything else of interest concerning the Alekhine?
He's not an Alekhine player himself. He covered these variations complying our (a teammate and me) specific request.
My impression is that White can stay on top by being willing to return the exchange in return for developing and keeping the strong passed c-pawn, e.g. 14...dxc3 15 Qxd8 Rxd8 16 Bxa8 c2 17 Ne2 Bb2 18 0-0 Bxc1 19 Nxc1.
I think the better way should be 14...dxe3 [An interesting alternative could be 14...Na6!? 15.Bxa6 (15.Bxa8 Nxc5 with compensation) 15...Qa5! with counterplay] 15.Qxd8 Rxd8 16.Bxa8 Nd7! 17.Ne4 Ne7 18.Bb7 Rb8 with compensation.

I think even 10...d5 is not simply to put aside, at least till a clear refutation is found to 11.c5 Nc8 12.Bf3 e5!? 13.Bxd5 exd4!?.
The most troublesome line we've found is 10.Nf3 Bg4 10.Be2 d5 (or 10...e6 with later transposition) 11.h3 Bxf3 12.Bxf3 e6 13.0-0 Nc6 14.cxd5 exd5 with a small but annoying advantage for White.


Very interesting, thanks! 

Did GM Skembris have anything else of interest concerning the Alekhine?

After 1.e4 Nf6 2.e5 Nd5 3.c4 Nb6 4.d4 d6 5.exd6 cxd6 6.Nc3 g6 7.Be3 Bg7 8.Rc1 0-0 9.b3 Bf5 
I agree that 10.Nf3 Bg4 11.Be2 d5 (or 11...e6 12.0-0 d5) 12.h3 Bxf3 13.Bxf3 e6 14.0-0 Nc6 15.cxd5 exd5 ought to be a bit better for White with the bishop pair, but there is not much else for White to play with; the black knights are not easy to dislodge and both sides have weak d-pawns.

The idea of 10...d5!?/?! 11.c5 Nc8 12.Bf3 e5!? 13.Bxd5 exd4!? [instead of 13...Nc6 14.Bxc6 bxc6 15.Nge2 with advantage to White - Marin.] is an interesting suggestion that certainly needs examination. 14.Bxb7 is obviously the critical try [14.Bxd4 Bxd4 15.Qxd4 Nc6 with the plan of ...Ne5] and now both 14...dxc3 and 14... dxe3 create tricky counterplay for the exchange. 

My impression is that White can stay on top by being willing to return the exchange in return for developing and keeping the strong passed c-pawn, e.g. 14...dxc3 15 Qxd8 Rxd8 16 Bxa8 c2 17 Ne2 Bb2 18 0-0 Bxc1 19 Nxc1.

This thread is really fascinating! -- it's quite revivified my interest in the Alekhine's. Thanks to all, but especially Paddy and Markovich, for some great ideas/suggestions.

I shall certainly take a look at Vukovic--Bogut, Markovich -- thanks v. much for this. Yes, this definitely looks the critical variation to me!

My point about 4 ...c6 really centred on the Miles Variation. It was simply that, by entering the Miles Var. via 4 ...c6 5 c4 Nc7 6 Be2 de 7 Ne5 g6 8 Nf3 Nd7, Black could if he wanted focus on this particular main line having effectively ruled out the 6 Bc4, 6 Bd3 and 6 g3 lines (these[i] fifth[/i] moves now being strongly met with 5 ...Bg4). Of course he'd have to be prepared to play the 6 0-0 Flohr after 5 Be2 de 6 de Bg4! 7 0-0 Bf3, and also the curious exchange variation seen in Gallagher--Baburin after 6 ed ed 7 Nc3 Bg4. Of course too this is of no theoretical moment whatsoever since in the Miles nothing is stronger than 6 Be2!. It's just an interesting option, that's all. (It could for example allow a putative Flohr player to test out one line without being ready or prepared to play the others!)

[quote author=103C2F36322B343E355D0 link=1228335807/35#35 date=1266163301]@Paddy: These 9...Bf5 ideas are fascinating.  Clearly I haven't been paying enough attention to recent developments, and not all that recent really.  

When play reverts to a normal ...cxd6 Exchange, Black doesn't seem to miss his tempo very much, probably because Rc1 and b3 aren't very useful there -- especially the former.  Black doesn't have his ...Nc4 ideas, but he does well enough with ...Nc8.  Anyway in practice Black scores well there.

Also I agree that after 10.d5 e5 11.dxe6 Bxe6, Black's resources seem to be adequate.  White pays a price for his slow early play.  I looked at 12.Nf3 Nc6 13.Nb5, but it doesn't seem that bad for Black.

I think that White's most challenging idea is 10.d5 e5 11.g4!, which you may be aware of since I (now) see that it was played in Dvoirys - Steffens, Overwart 2004.  It continued 11...Bc8 12.h4 f5 13.h5 (my silicon also likes 13.gxf5) 13...f4 14.Bxb6 axb6 15.hxg6 hxg6 16.Qc2.  Dvoirys won with his 400 Elo advantage, but I believe he could have beaten a much stronger opponent in this same position, which to me looks good for White.  So for the time being, this line looks to me like the most challenging rejoinder to 10...e5.

But what about 10...e6, with the idea that 11.Nf3 exd5 and 11.Be2 exd5 seem to offer Black enough play, while 11.dxe6 transposes.  That leaves 11.g4, when 11...Bxc3 12.Rxc3 Be4 13.f3 Bxd5 14.cxd5 Nxd5 15.Re3 (15.Qd2 Nxc3 16.Qxc3 Nc6 looks about even, though Black will have to watch out for the two bishops) 15...Nxe3 (15...Nc6!?) 16.Rxe3 Qh4+ 17.Ke2 Nc6 18.Bg2 (18.Qxd6? e5) 18...d5 (18...Rfc8!?; 18...Nb4!? 19.Qd2 a5) seems to offer Black pretty decent compensation for his material deficit.
(rest cut - different topic)
[/quote]

Thanks Mark; the sac idea with 10…e6 is an amazing resource, with Black getting two good pawns and unsafe white king to harass. Further analysis might reveal a way for white to coordinate (as seems to have happened in the piece for three pawns sac line  in the Slav with 6 Ne5), but until then…

However, I don’t think that Dvoirys-Steffens comes close to making 10…e5 doubtful. In some ways, “both sides stand badly” as Tarrasch once said. Black has an undeveloped queenside and badly placed knight at b6; but White is attacking with his kingside pieces undeveloped, his king in the centre and his rooks unconnected, so my feeling is that in the resulting King’s Indian-like positions Black should get his share of the chances, as long as he does not allow a stable blockade of the e4 square.

In the game itself, I think Black was doing OK until 17…Bxg4; instead, 17…Qe7 seems to give plenty of counterplay. Also instead of 18…Bxh3, 18…Bf5 was better, intending 19 Bxf5 gxf5!, again with enough counterplay, I think.

However, there several other issues to discuss in this game.

1)      After 11 g4, also to be considered is 11…Bd7 12 h4 e4!? To open the long diagonal and the e-file. I accept that the compensation is not immediately apparent. A sample line is 13 Nxe4 Qe7 14 Bd3 Na6 15 Bg5 f6 16 Bf4 Nc8 17 Kf1 f5 18 Bg5 Qf7 19 gxf5 Bxf5.

2)      After 11 g4 Bc8 12 h4 it is possible that Black does not need be in such a rush to play …f5, since White’s threats on the h-file might lack substance. Black can consider moving a knight to d7 or a6, or playing …a5 then ...Na6, watching for a favourable moment for …f5 (or …e4).

3)      Instead of 13 h5, you rightly identified 13 gxf5 as a critical alternative. I have looked at this in some detail without coming to a clear conclusion, other than that the play is difficult for both sides. I’ll post my analysis to the Alekhine group.

4)      Instead of  14 Bxb6, 14 Bd2 is critical, retaining this important bishop and intending to blockade e4 and then put pressure on black using the g and h files, and maybe the c5 break. I have so far found nothing satisfactory for Black. The 14…e4 pawn sac to prevent a blockade on e4 seems inadequate in this line.

I think that White's most challenging idea is 10.d5 e5 11.g4!, which you may be aware of since I (now) see that it was played in Dvoirys - Steffens, Oberwart 2004.  It continued 11...Bc8 12.h4 f5 13.h5 (my silicon also likes 13.gxf5) 13...f4 14.Bxb6 axb6 15.hxg6 hxg6 16.Qc2.  Dvoirys won with his 400 Elo advantage, but I believe he could have beaten a much stronger opponent in this same position, which to me looks good for White.  So for the time being, this line looks to me like the most challenging rejoinder to 10...e5.

But what about 10...e6, with the idea that 11.Nf3 exd5 and 11.Be2 exd5 seem to offer Black enough play, while 11.dxe6 transposes.  That leaves 11.g4, when 11...Bxc3 12.Rxc3 Be4 13.f3 Bxd5 14.cxd5 Nxd5 15.Re3 (15.Qd2 Nxc3 16.Qxc3 Nc6 looks about even, though Black will have to watch out for the two bishops) 15...Nxe3 (15...Nc6!?) 16.Rxe3 Qh4+ 17.Ke2 Nc6 18.Bg2 (18.Qxd6? e5) 18...d5 (18...Rfc8!?; 18...Nb4!? 19.Qd2 a5) seems to offer Black pretty decent compensation for his material deficit.

This really interests me, Markovich, not least because if you're right Black can confidently enter the Miles Variation via 4 ...c6 if desired. What then is your take on the 6 0-0 Flohr, in particular how Black should handle 9 Re1? -- is Short's 10 ...h6!? good/best? Also I think John Watson argued that White is better after either 9 c4 Ne7 10 Qd8 Kd8 11 Bd2! or the 'counterintuitive' (or perhaps we should say 'intuitive'!?) 9 Qe2 Nd7 10 Rd1!? Qc7 11 c4 Ne7 12 Bf4 Ng6 13 Bg3 Be7 14 Bh5 0-0 15 f4. I can't myself see why Black isn't OK, say with 11 ...a5 and 12 ...Nb6 in the first case and 15 ...a5 and 16 ...Nc5 in the second, but that's on a v. limited look! Forgive me if there's a thread somewhere on this that I haven't seen.
[/quote]

You're right that after 6.O-O Bxf3 7.Bxf3 dxe5 8.dxe5 e6, 9.Re1 Nd7 10.Nd2 Qc7 11.Nc4 is White's most challenging line after 6.O-O (it was featured, as you may be aware, in a recent update by MacDonald).  I think that Black does well enough there with ...O-O-O, so long as he realizes that a pure banzai attack against White's king isn't a winning proposition, since White falls back with g3 and Bg2 and winds up with a stronger king's position than Black.  What Black has to do is combine kingside expansion with pressure against White's e-pawn.  

For example, Vukovic - Bogut went 11...Ndb6 12.Qd4 Nxc4 13.Qxc4 O-O-O 14.a4 h5 15.c3 Be7 16.b4 g5 17.g3 g4 18.Bg2 Rhg8 and now Vukovic got in trouble with 19.b5?!, though he won when Bogut blundered.  MacDonald suggests instead a slower approach with 19.Qb3 h4 20.Ba3 preparing 21.c4.  I looked at this and formed the opinion that after 19.Qb3 h4 20.Ba3 hxg3 21.hxg3 Rh5 22.c4 Nb6 Black has enough pressure against e5 to constitute counterplay, e.g. 23.Bb2 (23.a5 Nd7 24.a6 b6) 23...Nd7 24.b5 Bc5 and Black can lift a second rook to the 5th rank if necessary to demolish White's e-pawn, while his king appears to survive. 

With all due respect to John Watson, I think that Black is solid enough in that queen exchange line and in the many other lines that White can play after 6.O-O, which I don't consider to be White's best move even though it's true enough that White can play it for a win.

However if I'm right in my opinion of Flohr's, I don't see how this enables 4...c6 to be played.  What's your point, to meet 5.Be2 with ...Bg4?  To me, that's going the wrong way around to get to play Flohr's.

In the July09 update, John Watson has analysed this
position in the context of the game Esserman-Yermolinsky, 2009 

He claims that after 10. d6 Be6 11. Nf3 Nc6 12. Nb5
is critical (12. Be2 Nd7 ! was played in Esserman-Yermolinsky) and gives some analysis

Probably 11.Nf3 is not strictly speaking a "refutation" since black can play 11...Be6 trasposing to the line with 10...Be6, but certainly this means that there is not much point in alalyzing Nc6 if white can force black back to the normal line.
However i have found this analisys on an italian site; i don't know if it's sound i'm simply pasting it here for you with a little translation;
Quote:
10.d6 Nc6 11.Nb5! Qh4+ 12.g3 Qxe4+ 13.Qe2 Qxh1 14.Bg5!

"14. ... Bxd6!? 15. exd6+ Be6 16. Nc7+ Kd7 17. Nxa8!? Qxg1 18. Be3 Qh1 19. Nxb6+ (19. Bxb6 Rxa8 20. 0-0-0 axb6 21. Bg2 Nd4 22. Qf2 Nb3+! 23 Kc2 Na1!+ with perpetual check) axb6 20. O-O-O Qe4 21. Bxb6 QxQ nearly =.

But stronger is 17. 0-0-0! Qxg1 18. Be3 Qh1 19. Bg2 QxR+ 20 KxQ"  and the commentator says that with Raf8 black can still hold.
Thank you Stigma for your suggestions!

10...Nc6?! 11 Nb5 is certainly challenging but i have seen somewhere a continuation which looks decent for black. I'll try to find it but i fear that the explanation was in italian so i have to translate it.
However Cox suggestion after 10. d6 is Be6!? and my question is if white has found an improvement over Movsessian-Luther Istambul 2003 (draw).


So many of the critical games in this line were played by Luther...

Funny, I always thought the refutation of 10...Nc6 was 11.Nf3 Bg4 12.Bf4 g5 13.Ne4! gxf4 14.Nf6+ Qxf6 15.exf6 0-0-0 16.Qc1! as first suggested by Burgess, and played in Bryson-Luther, Bled 2002 (despite the eventual 1/2-1/2). But 11.Nb5 etc. looks good too I admit.

After the more challenging 10...Be6, I suggest 11.Nf3 Nc6 (11...f6? 12.Nd4) 12.Bg5!? f6 (almost forced; 12...Qc8? 13.Nb5; 12...Qd7 13.a4 and Black has taken d7 square from the knight, while 13...a5 would make b5 a permanent outpost.) 13.exf6 gxf6 and this needs analysis; one sample line: 14.Bf4 Qd7 15.a4! Bf7 (edit: I found this corr. game which looked solid for Black: 15...Nb4 16. Rc1 O-O-O 17. a5 N6d5 18. Nxd5 Bxd5 19. Bxc4 Bxd6 20. Bxd6 Qxd6 21. Bxd5+ Kb8 22. O-O Qxd5 23. Qxd5 Rxd5 24. Rc4 1/2-1/2. Tushev-Alvarez, AR-2003-Q-00008 (1) 2003) 16.a5 Qe6+ 17.Kf2!? Nd5 18.Nxd5 Qxd5 19.Qxd5 Bxd5 20.Rd1 and White's initiative continues into the endgame.

In light of Tushev-Alvarez maybe White should still try his luck with 12.Nb5 or 12.Be2.

If fact my question is: if white avoids dxe5 and simply develops with Nf3 is black committed to a waiting move or there is an active plan that i am missing?


First, to clarify, after 1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. exd6 cxd6 5. c4 Nb6 6. Nc3 g6 7. Be3 Bg7 8. Rc1
O-O 9. b3 Bf5 10. Nf3 the idea is definitely to lose a tempo and play 10...Bg4, aiming to reach a normal type of position in which the d4 pawn is fixed, e.g.

Secondly, if White prevents ...d5 by playing 12 d5 himself, Black can reply with 12...e5, e.g.

Kc4 fxg4 61. Ng5 Kg7 62. Nxe4 Bf6 63. Nxf6 Kxf6 64. Kd4 g5 1/2-1/2

Of course, Black was eventually in difficulties in the Baklan game ("I swindled Vladimir Baklan with black in an Alekhine and drew." Nakamura) but that does not necessarily imply that Black was significantly worse in the opening. Although in most lines Black does indeed do best to adopt the ...d5. ...e6 pawn centre, there are many Alekhine games by strong players in which the ....d6, ...e5 centre provided enough counterplay and the structure of white pawns c4 and d5 vs black pawns d6 and e5 is a familiar one from the ...e5 Sicilian lines.

However, it is not clear to me why Nakamura did not play 11...d5 in the two games above; why is it necessary / better to prepare it with 11...e6? Unless White has something better than 12 c5 Nc8 13 0-0 it seems that the game is likely to transpose to

Ra2 35. Bxe4 Qd4 36. Bxd5 Qxd5 37. Nc4 Qxc5 38. Qc3 Rb4 0-1

Thirdly, 10 Be2 e5!? is (as far as I know) a new position, so we can only be tentative at this stage. My previous posts argued that Black has sufficient counterplay if White exchanges the pawns and the queens and that Black is sufficiently better off than in the lines with 9...e5. If White declines to exchange on e5 and develops with 11 Nf3 instead, then Black has several plausible moves e.g. 11...e4 (this forcing move should be analysed first - if good, problem solved!), 11...Nc6, 11...Qe7 and maybe 11...Na6.

Fourthly, we need to work out how to develop after 10 Be2 e5!? 11 d5, when the bishop might be misplaced on f5. (Baklan-Nakamura may or may not indicate the way to go.)

Fifthly, I began to worry whether there was a simple positional refutation of 9...Bf5 in 10 d5, intending Nf3-d4 with the sort of bind/space advantage  - based on a pawn structure known to be favourable to White (e.g. from the Sicilian Dragon) - which is the main point of the Voronezh move order, but I think Black's counterplay comes quick enough despite another loss of tempo with the bishop (!)  i.e. 10 d5 e5! and if 11 dxe6 Bxe6 12 Nf3 Nc6 13 Be2 d5! and if then 14 c5 d4! seems at least =+.

Your thoughts please!

Thank you Markovich! Frankly i started playing the c5 line partly for his provocative look and partly trying to avoid learning a lot of theory. Of course it's quite naive to play this defence and then try to avoid deep preparation in the sharpest line Grin so probably you're right the main line must be the best but i am still curious. I have found an old post by Cox himself on this forum in which he says he has stopped playing 6...c5 because the variation " has entered one of it's periods of supposed refutation, possibly forever" or something similar.
So i thought there must be a really strong improvement for white in this line.


There's a critical Tomas Luther game, but I forget the opponent, that is widely regarded as refuting the line with ...e6.  Maybe somebody else can cite it.  If you subscribe to this section, you'll find that Watson extensively treated 6...c5 7.d5 g6 in a couple of updates.  

You shouldn't take my word for it; I'm a chess nobody and there are those that will play 6...c5.  I'm just saying that when my own score is on the line, I'll play 6...Nc6. In some ways it depends on the level of opposition, and you might be able to get away with 6...c5 against sub-2200 opposition.

As for Paddy's line, which you question in another post, I would be interested to hear Paddy's answer.  But didn't someone say that a Nakamura idea was 9....Bf5 10.Nf3 Bg4 followed by an eventual ...d5, accepting a lost tempo?  Does Nakamura really have ideas or does he just play random moves?

Paddy's 9...Bf5 10 Be2 e5!? looks very interesting but what if white simply continues 11 Nf3?
11 ...Bg4? now is certainly weak since black is worse when he plays e5 instead of d5! in the "classical" variation.
My computer suggests 11...Re8 but after dxe5 white is simply a move up on the line shown in Paddy's game.Maybe this is still good enough for black but there must be something better than losing a tempo!
11...Qe7!? maybe this can be a decent waiting move but frankly i have not a real plan in mind...
Any suggestions?

Hi everyone! Smiley
my Alekhine repertoire is entirely based on Cox book and i am trying to update it so i have some questions:

-In the 4PA i used to play the 5...dxe5 6...c5 line with e6
but i heard that a refutation has been discovered; i guess it involves the sharp 10 d6 but can you show me the precise line which cause black trouble?

-Looking around in this forum i had the impression that Cox was too critical against flohr's Bg4/c6 in the modern.Markovich in particular alalyzed a lot of lines not covered by Cox, so the variation is sound in your opinion?

-In general there is something else in Cox's book that has been refuted or greatly improved in this years?

I'm sorry i understand that i am asking old questions of no interest for most of the members but i am new here and i am trying to update my Alekhine theory.

Thank You!


Welcome.  It's not that the theory of Alekhine's is changing that rapidly, it's more that nobody really understands it in the first place.  My opinion is that Flohr's Variation is fully viable.  Flohr's plus either the Miles or the Kengis would make a nice repertoire.  I also opine that 6...Nc6 against the Four Pawns Attack is sound, something I wouldn't assert about the alternatives.  Finally there is the Dread Voronezh, which can be avoided by ...exd6 or taken on via Paddy's new method or more traditional attempts discussed at great length in other threads here.

10...Nc6?! 11 Nb5 is certainly challenging but i have seen somewhere a continuation which looks decent for black. I'll try to find it but i fear that the explanation was in italian so i have to translate it.
However Cox suggestion after 10. d6 is Be6!? and my question is if white has found an improvement over Movsessian-Luther Istambul 2003 (draw).

-In the 4PA i used to play the 5...dxe5 6...c5 line with e6
but i heard that a refutation has been discovered; i guess it involves the sharp 10 d6 but can you show me the precise line which cause black trouble?

Hi everyone! Smiley
my Alekhine repertoire is entirely based on Cox book and i am trying to update it so i have some questions:

-In the 4PA i used to play the 5...dxe5 6...c5 line with e6
but i heard that a refutation has been discovered; i guess it involves the sharp 10 d6 but can you show me the precise line which cause black trouble?

-Looking around in this forum i had the impression that Cox was too critical against flohr's Bg4/c6 in the modern.Markovich in particular alalyzed a lot of lines not covered by Cox, so the variation is sound in your opinion?

-In general there is something else in Cox's book that has been refuted or greatly improved in this years?

I'm sorry i understand that i am asking old questions of no interest for most of the members but i am new here and i am trying to update my Alekhine theory.
Every suggestion is welcome!
Thank You!

If the above is correct, then this could constitute a significant strengthening of Black's resources against the Voronezh and White must look for improvements at move 10 or 11.


A. That's quite interesting.

B. Perhaps you'd be interested in joining the Alekhine Defense Working Group that some of us have started on Google Groups?  We haven't gotten very far, I must admit, but it has promise, and we could use another strong analyst.


I've now joined the group and uploaded my personal database of 100 games, mostly long play, for and against the Alekhine. I hope this will encourage others to contribute.

Attached is a training game to test 9...Bf5 19 Be2 e5 against the Voronezh, played tonight at 10 + 3 between myself as Black (FIDE 2133) and another club member (rated about 2200). Black's counterplay seemed sufficient and Black won after a blunder from White in a tricky position.

Easy to criticize. Maybe you could try to do better. I think we are 9 in this group and most of us have also a job during the day and a family at home. We are no professionnals but my impression from the first steps is that the delivered work is far from bad, I'd even say it is good.
By the way, the Alekhine is not really a hot topic among the GM's and so the theory is not evolving that fast. Taking his time and going for the best we can find and maybe create is in such circumstances an adhoc approach.
  

Yusupov once said that “The problem with the Dutch Defence is that later in many positions the best move would be ...f5-f7” but he is surely wrong.

Forgive me if I've missed any further discussion of this 9...Bf5 idea here at the forum. I used to play the Alekhine over the board but gave it up some years ago because of the Voronezh, but my interest has revived this week following some blitz games at my club with a 2200 Alekhine specialist.

As far as I was aware, 9...Bf5 was supposed to be suspect if White played the most precise reply 10 Be2.

Then 10...d5 11 c5 Nc8 12 Bf3! sets Black problems.

Now 12...Be6 looks horrible, but if 12...e6 13 g4 Be4 14 Nxe4 dxe4 15 Bxe4 it seems Black has insufficient compensation for the pawn.

Or if 12...Nc6 13 Bxd5 (better than 13 g4? e5!) 13...e5 (13...Nb4 14 Bc4 Qa5 15 Qd2) 14 Bxc6 bxc6 15 Nge2 and again I think Black is struggling to prove sufficient compensation.

But the insertion of the moves 9...Bf5 10 Be2 might just make the ...e5 plan more playable, e.g. 10...e5!? 11 dxe5!? (might not be the best now) dxe5 12 Qxd8 Rxd8 13 c5 Nc8!?

OK, the structure is still somewhat favourable to White (queenside majority) but with so many pieces on the board this is not yet an endgame, and the different piece placements (compared to the 9...e5 line) i.e. the insertion of Be2 and Bf5, and the knight retreating to c8 rather than d7, might prove important.

Of course, even if this does improve Black's chances after 9...Bf5 10 Be2, we should not get too excited, since it is not clear that the tempo lost after 10 Nf3 Bg4 allows Black sufficient "old-style" counterplay, e.g.

OK, only a rapid game, and with a big difference in ratings.

As I say, forgive me if this is old stuff here at the forum, but a quick search this morning didn't throw up any detailed discussion of this 9...Bf5 idea.


Having now played some training games with 9...Bf5 10 Be2 e5!? and spent some time analysing it with the help of an engine, I can find no advantage for White after 11 dxe5 dxe5 12 Qxd8+ Rxd8 13 c5 Nc8, e.g. 14 Nf3 (I have also looked at 14 g4, 14 Bf3, 14 Nb5 and 14 Bg5)  14...Nc6 15 0-0 Nc8-e7 and Black seems to be in quite good shape, not only alive but with various counterplay ideas: ...e4; ...Nd4; ...Bd3.

If the above is correct, then this could constitute a significant strengthening of Black's resources against the Voronezh and White must look for improvements at move 10 or 11.

Paddy - when I saw the Marin game with 9...Re8 I looked at it with curiosity thinking this could be a great TN but basically I agree with you, I really can´t see any long-term future for the move.

Ig - that plan with ...e6, ...Bd7-c6 has a certain logic to it, I will need to examine it more closely - I played Alekhines when I was younger and no real plans to go back to it but it would be handy to have it as a surprise weapon.


I know that this defense is used as a surprise weapon at high levels, but I think that Black is usually bluffing: he's not actually prepared to face the Four Pawns Attack, the Chase, or any of White's dangerous little ways of playing against this defense.  It may be a good assumption that a professional won't call that bluff, since it would require him booking up on a defense he's not likely to see very much.  But at the club or weekend Swiss level, I think Black will see his share of White's alternative ways of meeting Alekhine's and so he'll have to be prepared for them.  

And if Black must prepare, this ruins the Alekhine as a surprise weapon because there really is a large body of theory with which Black must be acquainted.  The whole thing about Alekhine's is that in most lines, White is not under much immediate pressure and so may select from a plethora of alternatives, with each of which Black must be familiar.

I've been preparing the Scheveningen Sicilian reached via 2...e6, and I've noticed that my Sicilian notes are much smaller than my Alekhine notes.  To me that says: play Alekhine's regularly and use the Sicilian as a surprise weapon.  Most Whites aren't accustomed to a Scheveningen reached other than via the Najdorf, so that idea has some heft to it.

I must confess that one of the things I like in being a member of chesspublishing.com is to be able to see posts by members with their opinions on some lines (and which many times are more interesting than the "sentences" in repertoire books)

the last post by Paddy fits this category

by the way, some months ago I mentioned other alternatives (played by Chetverik) on move 9, i) e6 followed by Bd7 and Bc6 and ii) Nb6-d7-f6.

John Watson made some analysis on these games and apparently Black is not Ok. But ...

Well, these two ideas: 9....Bf5 and 9...Re8 seem worth analising

this also means that Marin might do a CBM article on this variation


Yes, I also noticed the Marin game. Athough in general I'm an admirer of the Marin "brand", I suspect that 9...Re8 will prove to be  dead-end since, as waiting moves go, it is actually quite committal! 

I am suspicious of it for these reasons:

a) White can continue to delay Nf3, playing sensible waiting moves (Be2, h3) which are likely to be at least as useful than Re8; 

b) if Black wants to switch to ...e5 plans, then ...Re8 will be a complete waste of a tempo after dxe5, dxe5, Qxd8, Rxd8;

c) Even if  Black somehow avoids an exchange of queens on d8 after playing ...e5 (e.g. by playing ...Bd7 first), White can answer with d5 if he wants, after which the rook on e8 might well be misplaced (perhaps better on f8, supporting ...f5).

d) ...Re8 does not fit in well with the ...f5 plan, so that is another Black option that ...Re8 more or less rules out.

Therefore I would argue that ...Re8 is the opposite of flexible and its value depends entirely on White naively playing Nf3, allowing ...Bg4, when Black has gained a tempo on the 9...Bf5 line (always assuming that Re8 is useful in the "old-style" structure (Black pawn on d5, White pawns on d4 and c5).

Still, it's early days in the life of  these ideas, so let's hope we soon have some more games to study, so that any conclusions can be more concrete than the above.

Incidentally, Marin's opponent allowed ...Bg4 but did not push c4-c5:

1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.c4 Nb6 5.exd6 cxd6 6.Nc3 g6 7.Be3 Bg7 8.Rc1 0-0 9.b3 Bf5 10.Be2 d5 11.c5 Nc8 12.Nf3 Nc6 13.0-0 Bg4 14.b4 a6 15.Rb1 Bxf3 16.Bxf3 e6 17.a4 N8e7 18.b5 axb5 19.axb5 Na5 20.Be2 Nf5 21.Qd2 e5 22.Na4 exd4 23.Bg5 f6 24.Bf4 Nc4 25.Qb4 Ne5 26.Bxe5 fxe5 27.Nb6 Ra2 28.Bc4 dxc4 29.Qxc4+ Kh8 30.Qxa2 Qg5 31.Qd5 Nh4 32.Kh1 Qe7 33.Rbe1 Nf5 34.c6 bxc6 35.bxc6 Qc7 36.Nd7 Rd8 37.Qe6 Qc8 38.Rb1 Qc7 39.Rb7 Qa5 40.c7 Rg8 41.Qxg8+ 1-0

OK, only a rapid game, and with a big difference in ratings.

As I say, forgive me if this is old stuff here at the forum, but a quick search this morning didn't throw up any detailed discussion of this 9...Bf5 idea.

Against the 4 Pawns I play 6...Nc6 and either 9...Be7 or 9...Qd7!? with 0-0-0.  

Against the Modern I mostly play the Flohr Variation, 4...Bg4 5.Be2 c6.  This obliges me to be prepared for positions similar those that arise from the Exchange and ...exd6.  I also prepare 4...Bg4 5.Be2 e6; 4...dxe5 5.Nxe5 g6; and 4...Nb6.  I think that the latter is the best choice if you must have the full point, and I plan to play it more often.

Against the Exchange proper I play ...cxd6.  I am not very much afraid of the Voronezh, concerning which there has been quite a bit said in other threads here, and also by Watson in his updates.  In fact, his latest update has fairly deep analysis of a key Voronezh variation, with an conclusion satisfactory to Black.  Black sometimes lacks winning chances, but he is safe enough, I opine.

Against 2.Nc3 I play 2...d5, believing that Black's game after 3.e5 Nfd7 is fully adequate.  Contrary to what TN said, this does not, in general, oblige Black to enter a Steinitz French: only after 4.d4 c5 5.Nf3 does it become necessary to go into a French, and the early Nf3 is not White's best in the Steinitz.  Of course 2...e5 is an excellent move as well.

My choices are:

1) The dxe5, c6 line.
2) The Bf5, Bg4 line.
3) The exd6 line.

The book by Davies is not so bad for ideas.
  

Don't check me with no lightweight stuff.

Have to say 4 nf3 de 5 ne5 c6 must be worth considering in your repertoire- Sbort and Carlsen have played this with success. 5... nd7 is a crazy line (both sides) after 6 nf7.

The exchange system is a major  challenge - you need to be ready 5..ed is best.

Hello all, 

I really like the Alekhine, and have played it on and off (not too seriously, I have to add) for as long as I've played chess. I have the Davies book, and used to have The Complete Alekhine, but got rid of it. I was just wondering what variations (specifically), you play against: 

1. The Classical with Nf3 - I have always played ...Bg4 and ...e6 and followed the main lines for the most part, but people seem to think this is not a good way to play as Black. 

2. The Four Pawns- I've fiddled around with everything, but I've always had a soft spot for the early ...c5 and ...e6 line, with ...exd5 and ...c4. Who knows if it's good enough though. 

3. The Exchange - I've been under the impression that ...cd was bad on account of the Be3, Rc1, b3 plan, followed shortly by d5, so I've always played ...ed, but it's rather dry. 

What other materials would you recommend to learn the Alekhine? I'm taking it seriously now.  Grin



Hi Tony,

Firstly, I would recommend John Cox's book 'Starting Out: The Alekhine', published in 2005. It was given a positive review by Silman, among others: http://www.jeremysilman.com/book_reviews_jw/jw_starting_out_alekhines.html.

Against the main line (4.Nf3), the 4...Bg4 variation is a reasonable way to play for Black, although if White has a grasp of the theory he holds a slight edge (though this applies for nearly all Alekhine variations). 

I would also suggest studying the 4...de5 5.Ne5 c6/g6 and 4...Nb6 variations, both of which have been covered in recent Yearbooks. Being able to play 2 variations against the 4.Nf3 Alekhine will give you enough versatility for tournaments.

Against the Four Pawns, I would recommend the main line of 5...de5 6.fe5 Nc6 7.Be3 Bf5 8.Nc3 e6 9.Nf3 and now 9...Be7 or 9...Bg4 rather than the 6...c5 variations, mainly because the 6...Nc6 main line scores better. However, if you like the positions arising after 6...c5 and they are theoretically viable, then they should work for you.

Against the Exchange, if you are after a more tactical sort of position, play 5...cd6; if you are after a more positional sort of middlegame, play 5...ed6. 

If you cannot decide between the two, then you should keep in mind that against the former, the Voronezh is not as dangerous as theory would suggest, as John Cox shows in both Starting Out: The Alekhine and in a survey for ChessBase based on the aforementioned book. 

Andrew Martin also authored a DVD on the Alekhine Defence not very long ago, but I suspect that it would be a bit too basic for a 2100 player (I don't own the DVD, but generally the target market for Martin's DVD's is for players below 2000).

You didn't mention what you would play against 2.Nc3. If you often play 1...e5, then 2...e5 is a good solution. Ditto for French exponents with 2...d5 3.e5 Nfd7 4.d4 e6. However, even if Black does not have 1...e5 and 1...e6 in his repertoire, he can still reach a fully playable position with 4...c5, as pointed out by Markovich.

I suppose "bad" here means something like "giving White a greater chance for a slight advantage than the alternative."  That has sometimes been the reputation of 5...cd, even before the advent of the Voronezh (the Be3/Rc1/b3 thing), but isn't clear to me at any rate.  For instance, ECO, NCO and MCO don't give 5...ed as better. 

One bit this brings to mind is Nakamura's seeming preference for 5...cd, with the tempo-sacrificing idea of 9...Bf5 10. Nf3 Bg4 in the Voronezh, trying to steer the game into an old familiar type of position.

Hi, I ve been playing alekhine as my main defense against e4, but now im changing to scandinavian (i guess). I think that the most critical line is the modern Nf3, here i try different things but i think that the best play is with the miles. ...dxe5 Nxe5 c6. Against the four pawns i always play 
1.e4 Nf6 2.e5 Nd5 3.c4 Nb6 4.d4 d6 5.f4 dxe5 6.fxe5 c5 7.d5 e6 8.Nc3 exd5 9.cxd5 c4 10.Nf3 [10.Be3] 10...Bb4 11.Bxc4 Bxc3+ 12.bxc3 Nxc4 13.Qa4+ Nd7 14.Qxc4 Nb6 15.Qb5+ Qd7 16.Qxd7+ Bxd7 17.d6 Rc8 18.0-0 [18.Bd2] 
where black is a pawn down but you can play better than your oponent this ending and you always have traps in this line.
Bye!
