My next opponent plays like that. I don't think it is correct, but how to punish it...?




How indeed. The Black Lion is solid enough if Black remembers that playing ....g5 is not obligatory.

In the 8 Ba2!? Qa5!? line, Asrian-Dizdarevic went 9 Bd2 ed 10 Nd4 Qe5 11 Nf3 Qh5 with an quick draw, but I fear 11 Nf5 might be a big improvement ...

8 Ba2!? ed 9 Nd4 Nc5 looks much more reliable to me now. Here 10 Re1 a5 transposes to 7 Re1 c6 8 a4 a5!? 9 Ba2 ed 10 Nd4 Nc5, where Black's stats are reasonable. I've largely given up playing the Hanham because I had trouble winning against solid lower-rated opponents (at my level something a bit more dynamic is preferable I think), but this looks quite playable?

I don't know if the games mentioned by Toppy in this thread are relevant but I remember thinking the setup was advantageous way back then.

Currently the last post on that thread is, Quote:
Two or three years on, I'm wondering if anyone has further thoughts or analysis on this 8 Ba2!? plan. I notice that the Bosnian GM Dizdarevic plays 8 ...Qa5!? here. Does Bauer cover this? Whatever its status I guess it's tricky and maybe less likely to run into a standard Nh4-f5 manoeuvre ..
by Michael Ayton.  This looks interesting and I also wonder how good Houdini's recommendation of 8...exd4 9.Nxd4 Nc5!? is.

Elsewhere on chesspub the Re1 setup has been discussed.  I wonder which one is stronger or if they're of equal value.

I believe the 5.g4 variation is now in serious trouble due to the following recent game:

[Event "Sydney International Open"]
[Site "Parramatta, NSW"]
[Date "2010.04.11"]
[Round "9.4"]
[White "Chao, Li"]
[Black "Malaniuk, Vladimir"]
[Result "0-1"]
[ECO "C41"]
[WhiteElo "2613"]
[BlackElo "2582"]
[PlyCount "109"]
[EventDate "2010.04.07"]
[EventRounds "9"]
[EventCountry "AUS"]
[SourceDate "2010.04.07"]

1. e4 d6 2. d4 Nf6 3. Nc3 e5 4. Nf3 Nbd7 5. g4 Nxg4 6. Rg1 Ngf6 7. Bc4 h6 8.
Be3 c6 9. dxe5 dxe5 10. Qd3 b5 11. Bb3 Qa5 12. O-O-O Ba6 13. Ne2 c5 14. c4 bxc4
15. Bxc4 Bxc4 16. Qxc4 Qb4 17. Qxb4 cxb4 18. Nd2 g6 19. f3 Nb6 20. Kb1 Nfd7 21.
Rc1 Be7 22. f4 exf4 23. Bxf4 Nc5 24. Be3 Rd8 25. Nd4 Nd3 26. Rc2 Bg5 27. Bxg5
hxg5 28. Nc6 Rd7 29. e5 Rh4 30. Nf3 Rc4 31. b3 Rxc2 32. Kxc2 Rc7 33. Kxd3 Rxc6
34. Nd4 Rc5 35. Rxg5 Nd7 36. h4 Nxe5+ 37. Ke4 f6 38. Rg2 Kf7 39. Rc2 Rxc2 40.
Nxc2 a5 41. Nd4 Kg7 42. Ne2 Kh6 43. Ng3 Ng4 44. Kf4 Nf2 45. Ke3 Nd1+ 46. Kd3
Nc3 47. a3 f5 48. axb4 axb4 49. Ke3 Ne4 50. Ne2 Nc5 51. Nc1 Kh5 52. Kd4 Na6 53.
Kc4 f4 54. Nd3 f3 55. Kd4 0-1

Trying to avoid this line with Qe2 or avoiding de5 isn't any better for White.
  

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

Hi.

Just saw in the april ChessBase ChessLetter that Bologan has recorded a DVD about the Philidor.

"
Last summer Bologan recorded DVDs about the King's Indian Defence and the Caro-Kann, two openings from his own repertoire. Bologan follows a concept of his own when presenting openings. Similar to classical opening books he only shows the beginning of the illustrative games and breaks off at a suitable moment. This has the advantage of showing you more lines. And Bologan believes that not seeing the whole game is not such a big drawback. Now Bologan has recorded DVDs about the Philidor and the Rossolimo Variation in the Sicilian. The Philidor is an underestimated but completely playable and complete defence against 1.e4 ( via 1.e4 d6 2.d4 Nf6 3.Nc3 e5); the latter opening allows you to give to the Sicilian your own more positional slant.
"
Sounds like a must buy for Philidorians. 

It will be interesting to see his view on the Hanham and other related topics such as the 1.e4 d6 2.d4 Nf6 3.Nc3 e5 4.dxe5 queenless middlegame.

Cheers / Anders

Simply because I don't play this for either side at the moment and I therefore have not analysed it in detail. I'll comment when I feel I have something that might be worth saying!

I found these lines as the Black Lion. I use them for blitz games, since black's development is fairly straightforward.
4.f4 is the most difficult move to face, but in blitz games most white players go for the 4.Nf3 line, in which black can get a nice position where white doesn't have much space to manuever.

Question for 1.e4 gurus:

What is supposed to be White's leading plan/best play for advantage against 1.e4 d6 2.d4 Nf6 3.Nc3 e5 4.Nf3 Nd7?  Am I right that something like 5.Bc4 Be7 6.0-0 c6 7.a4 0-0 is played, and if so, then what?  

Your line is correct but as book says i Here personaly don't continue here with 8. Re1 rather i continue here with my favorite Prophylactic move 8.a5!? with the idea not to allow b6 later which equalizes after a5

He then recommends the positional play with the a4 restraint and a later d5.


Oh, I havn't heard of a refutation of Shirov's Gambit - and that by the master himself. How does tame his own invention? Do you have a few lines?
Thx

I won't comment on Shirov's proposed refutation, but wish to point out that there is interesting material in the public domain at

http://www.newinchess.com/SOS/Default.aspx

both in the pdf extract (right of screen ) and in the current Game of the Month article. There is also an earlier annotated Game of the Month, Brkic-Trevelyan, available in the downloads section.

Theoretically Black is probably fine but there are many chances for him to go wrong and in practical play I assess White's chances as excellent if familiar with the main ideas.

MnB the rook is on f7 so no Qg6 here. You may be confusing it with the line white sacrufices his bishop before black castles, where black rook would be on h8, and Qg6 is indeed very good for black.


You are absolutely right. This version with 6.Ng5 0-0 looks like a slight improvement, but I rather would still have Black.  I disagree that it is hard to play, though Black should know 10...b5 indeed. After that it is exactly the recipe I already gave: activate the light pieces as quickly as possible. That knight can stay on a8 for a while.
Pilnik-Najdorf, Buenos Aires 1941, already was a model game. White's extra rook never was a match for Black's knights.
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

The idea of 10...b5 versus 10...b6 is not to give the chance to white's knight to grab a pawn before his own unavoidable capture.

Additionally it gives black the ...b4 resource in certain variations.. Of course the move has its drawbacks too.. For instance the Ba6 move after white's 0-0 will not be played with a gain of tempo anymore

11. a3 Bb7, 12.d5 Qxa8 (better than Bxa8 since the bishop had to be redeployed to b7, while d8 is not a good square for the queen), 13. Qe2 e6, 14. 0-0 is unclear

11. Nxb5? Qa5+, 12. Nc3 Nxe4, 13. 0-0 Nxc3, 14.bc3 Bb7 and black is better..

11. 0-0 Bb7, 12. Nxb5 Bxa8, 13. f3 d5 and black is more than OK

11. Qe2(d3) a6

11. f3 Ba6!, 12.de5 Nxe5, 13.Nd5 Nxd5, 14. Qxd5 Bh4+, 15. Kd1 Bb7, 16. Qxb5 Bc6, 17. Qb3 d5! -/+
Canneva - Leignel 2003

11. dxe5 Nxe5, 12. 0-0 Bb7, 13. Nxb5 Bxa8, 14. f3 d5 is  Huber - Schaeffer 1997 and must be white's best try.. He has 3 pawns and a rook for two pieces but black's pieces are much better positioned.. Therefore, unclear..

The above is based on Bauer's book..

He mentions some other choices for white's 12th move in the last line, but none changes the general evaluation.. At White's best, the position is unclear and maybe a little bit easier to play with black..

Personally I have scored 100% with Black after 10...b5 - 3 out of 3, two of those games were over by move 20 (FIDE 1800ish opposition)
