I must say i'm not terribly impressed with this DVD.  85% of the presentation is on the position after these moves:

1. e4 e5   2. Nf3 Nc6   3. Bb5 a6   4. Ba4 Nf6   5. O-O b5   6. Bb3 Bc5  7.a4 Rb8.   

This is the move that differentiates what Shirov refers to as the Tkachiev systerm.  This seems odd given he makes many references to this as "my lopez".  Unfortunately, there is very little disussion of black or white deviations.  In a roundabout way, it becomes clear that his intention is rarely to play Bb7.  Presumably if white doesn't play an early a4, he would aim for a quick Bg4, giving him more direct attacking chances against white's center than the solid Bb7 lines.

The video was insightfull at first, as he shared many thoughts about GM prep, especially the impact of modern computers.  However, he rambled a lot and seemingly did little preparation for the lecture.  Frankly, i feel he glossed over black's best moves (although he would vaguely mention them) and spent too much time on the difficult positions black ended up in. 

I don't need an opening video to "sell" me the variation with brilliant wins from the black side, but this video lacked any sort of enthusaism or "hope" from a presenter who has made this his primary defense for over a decade!   I got the impression he was trying to avoid giving away too many secrets.  I often sat twiddling my thumbs while our hero mumbled "uhh",  "ermm", and "i forget" as he tried to solve tactical problems in non-critical positions without the use of a computer. 

This is basically no more than an interesting games collection - too incomplete to form the basis of a repertoire, and too narrow in focus for a state of the art theory survey.  Sadly, none of these games impressed me with black's supposed "counterplay".  There is very little strategical explanation which indicates any logical motivation behind his choice of lines.   Most of the video is spent demonstrating that black can usually draw after dropping his b5 pawn, and that the Nxe5 fork trick doesnt necessarilly win for white.  I'm left wondering why bother playing the Rb8 system at all. 

FYI, the Chesslecture.com 3 part lecture series on this exact same opening is certainly a more suitable introduction for the 1600-2000 crowd.  Humorously, the most usefull thing i gained from Shirov's video was a hint that he could possibly play 7... Bb7 in the futre.


Thanks. It is the kind of helpful posts that dare to mention that an incredibly strong player like Shirov can produce such 'lemons'. I had the same impression with his 6.Bg5 Najdorf (Absolutely useless) and the Caro Kann 3.e5 which was somewhat better.

In fact most honest seems Kasparov in his Najdorf's DVD: Get Fritz and produce a novelty. I did, and it was useful vs Renier Vazquez (GM 2570) and Soltanici (IM 2400).

Even some good authors like Bologan (I love his French DVD) can get worse DVD's depending on what they are covering: The Philidor one was kind of boring, as was the Rossolimo one. The Sicilian ones... too vast a subject. Certain lines he recommends (like one by Lanka vs Scheveningen with 6.g4 a6) are completely out of date...

Shirov must be the most unprepared author I have seen... What is the point of analyzing a position while presenting???

One author that seems a pretty safe bet is Kasimdhanov (The Path to tactical strength fabulous) even though I prefer Bologan's 1 DVD to his 3 covering the French...

If i remember correctly Svidler used the same line deviating somewhere to beat easily Caruana in the Italian Championship this year. This is a promising road for White as it seems if we believe the engines' evaluations. Definately a more practical way than entering the complicated main lines.


Probably not, because 1. Caruana did not play any game in this line in the Italian (Team) Championship, and 2. Svidler did not participate at all.
And no, I do not believe in the engines' evaluations on positions with material imbalance for positional compensation. Quite the opposite.

After looking at the position in more depth, it does seem that Black has decent counterplay after Anand's 17...Ne7.
Salgado Lopez tried a new pawn sacrifice against Kazimdzanov: 7.a4 Rb8 8.Nxe5 Nxe5 9.d4 Bxd4 10.Qxd4 d6 11.f4 Nc6 12.Qc3 Ne7 13.f5!? (instead of the regular 13.Qd3) 0-0 14.Qe1 Bb7 15.Qh4 Nxe4 16.Nc3 Nxc3 17.bc3 Bd5 18.f6 with interesting compensation, although it's possible that after the move played (18...Ng6) the Queen shouldn't go at h5.

Shirov claimed that after 16...Nf4 17.Be3 Black has nothing else but a pawn less. Did he change his mind?
I only know the "new" move 17...Ne7, which was played in a blitz game between Svidler and Anand, and which does not inspire much confidence. Do I miss something?

I think you mean 23.Na7, and it's not clear that this is really problematic for Black as 23...h6 24.Bxh6 d5 25.Nc6 Qd6 26.Qxd5 Qxd5 27.exd5 Ra8 "and Black may have compensation for the piece" (per Van Delf and Ris in ChessVibes Openings #108); meanwhile, 16...Nf4 avoids the line entirely.

I know this is an old thread... but since the main line of Shirov's sacrificial idea (7...Rb8) is at best problematic for Black, due to the stunning 21.Na7! of the game Smeets-Shirov, Wijk 2011, Black has either to switch to the positionally unwise 7...Bb7, or use the Moeller move order. IMO the main line after 5...Bc5 6.c3 b5 7.Bc2 d5 is not bad for Black, either with the 12...Nxf2 exchange sacrifice, or with Ivanchuk's brave king march (12...Rb8). Black looks just marginally worse, in both variations.
In the Moeller move order 5...Bc5 6.c3 b5 7.Bc2 (7.Bb3 d6 7.a4 Bb7 is surely enough much better for Black than the positions white has not commited himself to c2-c3) d5 8.a4!? (ala-Anand) is IMO not particularly threatening.
Eagerly looking for comments!

The 5 .. Bc5 6 c3 b5 vs 5 .. b5 6 Bb3 Bc5 thing does seem to be a genuine trade off rather than a straight loss.

Its 6 Bc2 d5 (d6 surely has to be a slightly worse version of the main line?) vs 5 .. b5 6 Bb3 Bc5 7 a4 which the old Everyman book seems to take relatively seriously.

Perhaps theory has clarified whether this is worth it or not by now Smiley Could do with a good book on all these lines actually, as there's so much new theory around.

My first guess would be White because of the extra option a2-a4 and an initiative on the Queen's Wing. Very likely it will be more complicated.
  

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.

In my new database including corr. Games (which was not included in my ChessBase 2010) I get:
7.Bb3 with 602 games with a score of 56,8%
7.Bc2 with 572 ganes with a score of 60,2%
7.d4 with 34 games with a score of 55%

The score is rather the same

I cannot understand the big difference in the number of games compared to your search as long as we are searching the same position:  1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Bc5 6.c3

I can understand Black if he thinks 7.Bc2 is inferior to 7.Bb3. In that case he gives White the option of doing a worse move. Otherwise I echo your question.

  

What kind of proof is that?

In my Mega2010 there are about 1000 games with 6.c3 and about 840 games with other than 6...c3. and after 6.c3 7.b5 the statistics in Mega shows:

Move      Games   Score      
7.Bb3      399         56.5%
7.Bc2      307         60.1%

Perhaps this figures don’t prove very much but I fail to see them supporting  that  “almost allgames transposes” (only 399 of roughly 1800 games) neither that “7.Bc2 should be inferior to 7.Bc3”.


Strange, I have done a research on chesslive where after 6..b5, statistics give 2628 games with Bb3 and 489 after Bc2. I guess that 2628 are because of the transposition, that would mean Bb3 is more important. One thing I don't understand is why would Black play first Bc5 and then b5 because it offers another reasonable choice for White (Bc2) instead of the immediate b5 followed by Bc5 (only Bb3 is possible). Could someone respond to me?

Oh and in the whole Ruy Lopez vs Slow Italian theme, I never understood which color the Black's pawns a6-b5 vs a6-b7 expansion was favouring.

Just a small question. I remember reading Jansa's Dynamic Chess Strategy book some years ago where he gave a nice strategic variation for White against this Black's system. Could anyone tell what is it and if Shirov covers a Black's antidote? If i remember correctly Jansa didn't like taking the pawn and he prefered a Bg5 approach instead

Has anyone purchased this DVD?  A friend of mine did.  If you did, too, then perhaps a request for a 110% refund is in order.

Possibly I am being too harsh, as the entire DVD has not yet been viewed, and I base my statement solely upon glaring tactical errors found in Shirov's analysis of the first game on the DVD:

[Event "World Cup"]
[Site "Khanty-Mansiysk RUS"]
[Date "2009.12.01"]
[Round "4.2"]
[White "Svidler, P."]
[Black "Shirov, A."]
[Result "1/2-1/2"]
[ECO "C78"]
[WhiteElo "2754"]
[BlackElo "2719"]
[PlyCount "84"]
[EventDate "2009.11.21"]
[EventType "k.o."]
[EventRounds "7"]
[EventCountry "RUS"]
[Source "Mark Crowther"]
[SourceDate "2009.12.06"]

I have edited this game so as to avoid copyright infringement.  Cut and paste this game into your favorite database/chess playing program, and start the weakest chess engine you own.  Then play through the analysis in the notes to moves 12 and 25. 

This is inexcusable.  A player of Shirov's caliber should not be turning out a product such as this.  A modicum of preparation is all that is required to guard against the occurrence of such errors.  To my mind, when considering the sheer(ov) amount of DVD's he has been producing, one has to wonder if he is merely cashing-in while the getting is good.

From what I've read here and there on this forum, other Chessbase DVD's suffer from similar flaws.  I can't speak to that allegation, as I don't own any of them...and probably won't anytime soon.  However, if the above is any indication of the (lack of) quality of these DVD's in general, then perhaps such criticisms are more than justified.

  

I don't think I really know any more than other people don't really know.

Very interesting - thanks Stefan. There must be much gold hidden in the old magazines.

I think the Russians say "All is new that is well forgotten" or something like that.

It can be argued that this line has more in common with the Classical defence than the Archangel (although admittedly it can transpose to the latter if Black plays ...Bb7). Or you could say that it is a modern interpretation of the Moeller defence, an early Alekhine favourite (generally played without ...b5).

There is definitely a case for calling it after Tkachiev though. Practically the earliest game with this by a modern strong play is his game against Bologan from Tilburg 1994. Wedburg's annotation at move 6 reads "Not the Arkhangelsk variation"! Very helpful.

On the other hand, historical purists could equally argue that it should be named the "Morphy defence" (Loewenthal-Morphy, game 1 of their match in London 1859)!

roughly 6 hours of video:

11 games on above position
1 long game on the exchange

Shirov doesnt really offer a conclusion.  I presume he thinks it is a good system since it has become his primary weapon.  Yet, something gives me a feeling we might be seeing some 7...Bb7 from him in the future instead of the 7...Rb8 featured in the video.

The conclusion is that this is now a good system for Black after all?

1. e4 e5   2. Nf3 Nc6   3. Bb5 a6   4. Ba4 Nf6   5. O-O b5   6. Bb3 Bc5  7.a4 Rb8.   

This is the move that differentiates what Shirov refers to as the Tkachiev systerm.  This seems odd given he makes many references to this as "my lopez".  Unfortunately, there is very little disussion of black or white deviations.  In a roundabout way, it becomes clear that his intention is rarely to play Bb7.  Presumably if white doesn't play an early a4, he would aim for a quick Bg4, giving him more direct attacking chances against white's center than the solid Bb7 lines.

The video was insightfull at first, as he shared many thoughts about GM prep, especially the impact of modern computers.  However, he rambled a lot and seemingly did little preparation for the lecture.  Frankly, i feel he glossed over black's best moves (although he would vaguely mention them) and spent too much time on the difficult positions black ended up in. 

I don't need an opening video to "sell" me the variation with brilliant wins from the black side, but this video lacked any sort of enthusaism or "hope" from a presenter who has made this his primary defense for over a decade!   I got the impression he was trying to avoid giving away too many secrets.  I often sat twiddling my thumbs while our hero mumbled "uhh",  "ermm", and "i forget" as he tried to solve tactical problems in non-critical positions without the use of a computer. 

This is basically no more than an interesting games collection - too incomplete to form the basis of a repertoire, and too narrow in focus for a state of the art theory survey.  Sadly, none of these games impressed me with black's supposed "counterplay".  There is very little strategical explanation which indicates any logical motivation behind his choice of lines.   Most of the video is spent demonstrating that black can usually draw after dropping his b5 pawn, and that the Nxe5 fork trick doesnt necessarilly win for white.  I'm left wondering why bother playing the Rb8 system at all. 

FYI, the Chesslecture.com 3 part lecture series on this exact same opening is certainly a more suitable introduction for the 1600-2000 crowd.  Humorously, the most usefull thing i gained from Shirov's video was a hint that he could possibly play 7... Bb7 in the futre.

Yes, i see now in Johnsen/Johannessen's book that 6.d4 is the move for White.

Just a question that came now on my head. Is it possible to play 3...a6 4.Ba4 b5 5.Bb3 Nf6 justo to avoid some sidelines like the delayed exch var? Given that 6.Ng5 d5 7.exd5 Nd4 is equal according to what i know, can White benefit from this move order?

If statistics are to be trusted, 6.d4 is pretty strong; White wins more than 70% of the games.

As I can see the Black "...d5 possibility" isn't a threat as in Möller Defence anymore.

Is it good for White or Black? Depence on the value of 7.Bc2 d5 in Möller Defence

Another variation in Möller Defence is 5...Bc5 6.Ne5 which could be interesting for White.

It should be noticed that the DVD is about Modern Archangels 4...Nf6 5.0-0 b5 6.Bb3 Bc5 and the Möller isn't any issue.
  

What kind of proof is that?

Agree that Onischuk is a strong advocate for Black. He has played 11 games with 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5. O-O Bc5 6.c3 b5 7.Bc2 d5 with 1 win, 1 loss and 9 draws. The loss was “way back in 1996” -  Luz –Onisckuk, Bundesliga [Porz-Magdeburg] 1996.

What does Shirov think is the critical line on the DVD? By the way what is the name of the DVD?

After 7...d5 8.d4 dxe4
Shirov-Ivantsjuk, 1998 1-0
Shirov-Onischuk, 2000 ½
Zhang Zhong-Onischuk, 2001 ½

Topalov-Shirov, 2001 ½
Svidler-Grisjuk, 2001 1-0
Lautier-Onischuk, 2004 ½
Svidler-Onischuk, 2005 ½
Hracek-Delchev, 2006 ½
Galkin-Lastin, 2008 ½

So I maintain that Onischuk is the man to beat. My question remains relevant: is there a way to an advantage for White?

They call it the New Archangel in the Everyman book from 2000 and in every article I've seen on it.  I'm sticking with that name.  I don't see any reason to name it after Tkachiev.

It's great that Shirov is doing a new DVD on it.  I remember on one of his Spanish DVDs he mentioned that he and a group of top GMs had analysed one of the main positions out until something like move 30 but that he wasn't allowed to reveal any of it!  Maybe he can talk about this now on the new DVD.  I think he devoted a lot of time to it on his Spanish 3 DVD already.

I also started Fritz12 while looking in the database and he evaluates 7...d5 8.d4 as +=. Agree that this doesn’t say very much but all things together.

Shirov -  Ivanchuk 1-0, 1998 and Shirov – Onischuk ½-1/2, 1999 and Topalov-Shirov 1-0, 2001. The only Shirov games I have in Mega2010l. Svidler has 3-0 against opponents between 2557-2669.

I think it is not totally wrong to say that the statement “ 7.Bc2 is inferior to 7.Bc3” is a bit stretched

What is pointing in the other direction?

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Bc5 6.c3 b5 7.Bc2 d5.

The general consensus is that c2 is a better square for the bishop than b3. This particular case might be an exception indeed, depending on the strength onf 7...d5. Shirov has lost twice with it, but Onischuk has drawn a couple of times against first class opponents.
Is there a route to an advantage for White after 7...d5 ? If not Daniel has a strong case.

In my Mega2010 there are about 1000 games with 6.c3 and about 840 games with other than 6...c3. and after 6.c3 7.b5 the statistics in Mega shows:

Move      Games   Score      
7.Bb3      399         56.5%
7.Bc2      307         60.1%

Perhaps this figures don’t prove very much but I fail to see them supporting  that  “almost allgames transposes” (only 399 of roughly 1800 games) neither that “7.Bc2 should be inferior to 7.Bc3”.

I have usually seen 5...Bc5 6. c3 b5 7. Bc2 given as better for White than 7. Bb3 (= 5...b5 6. Bb3 Bc5 7. c3), but never, as far as I know, the other way around.

Yeah but the Moller almost always transposes to the Neo Archangel unless white plays 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Bc5 6. c3 b5 7. Bc2 which is an inferior square to b3 as it allows 7... d5.

Yes, the nomenclatur in wikipedia tells:
4...Nf6 5.0-0 b5 6.Bb3 Bc5 (Modern Archangel Defence)
4...Nf6 5.0-0 Bc5 (Møller Defence)

The variation against the Ruy Lopez presented in meticulous detail by Alexei Shirov (3...a6 4.Ba4 Nf6 5.0-0 b5 6.Bb3 Bc5) has so far had no recognised name and Shirov himself has named it after Vladislav Tkachiev, the 2007 European champion, the Tkachiev Ruy Lopez. In fact the grandmaster from Kazakhstan has played a few important games with this system, but it would have been just as justified to name the variation after our author himself, because since 1996 Shirov has not only played numerous games with it, but recently he has turned it into his main weapon against 1.e4 - with splendid success and a lot of imitators. The super grandmaster now shares all this collected knowledge with his viewers. Apart from the Exchange Variation (to which Shirov also devotes a model game) White has hardly any serious deviation after 3.Bb5, making of the Tkachiev Variation a good weapon against the Ruy Lopez. Video running time: 6 hours.


Strange, I thought this line was known for the longest time as The Moller Variation of the Ruy.

definitely picking this up.  I love Shirov's videos.  Always great observations, analysis, and secrets such as when he provided to unplayed refutation to his own 5. g4 in the Philidor.
