Game of the Month: October 2011

WHO:
Kamsky, Gata (2756) Vs. Svidler, Peter (2740)
© FIDE World Cup Khanty Mansiysk 2011 Website
This knockout tournament was played in Khanty-Mansiysk in Siberia. Gata Kamsky is currently the highest rated player in the USA but originally came from Novokuznetsk in the USSR and so arguably had some home advantage. He was a very strong chess prodigy with an overbearing and irascible father who often issued violent threats to other players. Gata gave up chess in the last 1990s and went back to academia, graduating with a law degree.. He returned to chess in 2004 and has returned to the elite. He is currently ranked 10th in the world.
Peter Svidler is a Russian Grandmaster from St. Petersburg. He’s one of the most relaxed of the World’s top GMs. His theoretical knowledge perhaps lags behind that of his colleagues but he’s a noted specialist in the Grunfeld. He has a weakness for a lot of things English – especially cricket! Peter’s current rating puts him at number 16 in the world but after such a successful World Cup he is currently running at 9th in the world

WHERE:
World Cup 2011, Khanty Mansisk

WHY:
This month I’ve chosen to annotate a game between Gata Kamsky and Peter Svidler from the World Cup. Not only did I find the game interesting (check out the double rook sacrifice by Svidler!) but it was also important in terms of the tournament as Peter Svidler went on to win the competition.

Black develops his bishop more actively than in other variations of the Ruy Lopez and points it towards White’s king. The downside is that Black has been forced to play an early …b5 and so his queenside is looser than normal.} 7. a4 {And so White immediately exploits it.} Rb8 8. axb5 axb5 9. c3 d6 10. d4 Bb6 11. Be3 {A very rare sideline. Instead of trying to pick up the b5 pawn White simply gives greater support to his centre and prepares to develop his knight to d2.} (11. Na3 {is the mainline, when Black normally gives up the b pawn to generate counterplay on the kingside.} O-O 12. Nxb5 Bg4 {At the cost of a pawn Black has a lot of pressure on the d4 pawn and an annoying pin on the d1-h5 diagonal. White’s knight on b5 is also rather offside. Shirov has attempted to defend this position a few times recently, and, while his score hasn’t been very good, the positions he’s reached have been respectable theoretically.} 13.

Qd3 Qd7 {gives Black an advantage with the bishop pair and a favourable structure.}) (16. Qc3 $5 { would be an interesting pawn sacrifice. The idea is to allow the bishop back to c2.} Nxe4 (16… b4 17. Qc2 {and at least Black doesn’t have access to the b4 square although} Na5 18. Ba4 Bxe4 19. Nxe4 Rxe4 {is only decent comp for the pawn}) 17. Nxe4 Rxe4 18. Bc2 (18.

Bxf6 {and Black has an extra pawn and is obviously on top.}) 18… Re8 19. Qd3 g6 20. Qxb5 {when Black can try} (20. Bxh6 $6 Qf6 {is very good for Black.}) 20… Nxd4 $5 {with a good game}) 16… Na5 17.

Black’s 15th move removed a defender from the centre and now White’s initiative becomes very strong.} Nd5 ({It’s also possible to throw in an exchange of pawns first.} 17… dxe5 18. dxe5 Nd5 ({But not} 18… Bxe3 $2 19. fxe3 $1 {when the pressure on f7 is decisive.} Nd5 (19… Nd7 20.

Bxh6 {So, due to White’s kingside initiative he has picked up a pawn and looks to have a fantastic position as Black’s kingside is also rather loose. However the Anglophile from St. Petersburg succeeds in more than just complicating the issue.} Nc6 {And this is the problem; White’s centre is actually extremely vulnerable and if the centre collapses Black’s bishops will come to the fore.} 20. exd6 {I think this is an error as Black’s pieces now become too active.} ({Instead} 20.

However this move looks risky with the queen on the long diagonal but the tactics work out for White:} dxe5 (20… Nxd4 $5 {is another interesting try but White comes out on top in the complications:} 21.

Qd2 {is a bit more comfortable for White with his favourable structure.}) 21. Ne4 {I looked at this position in quite a lot of depth and in the end decided that, oddly, White’s not actually better here. The problem is that d4 is still weak and when that pawn drops Black manages very strong counterplay against White’s king.} Qb4 22. Ba2 (22. Bd2 {might be an improvement at this point but White is definitely not better. The following line looks logical:} Nxd4 23. Bxb4 Nxc2 24. Bxc2 Nxb4 25. Nf6+ Kh8 26. Nxe8 Nxc2 27. Rac1 Bxf3 $1 28. Rxc2 (28. gxf3 Nd4 {threatens both the knight on e8 and …Ne2+ regaining the exchange.}) 28… Be4 29. Rxc7 Rxe8 30. Rxf7 {with an interesting endgame. Generally I prefer the bishop pair to a rook and two pawns and so would plump for Black here.}) 22… Nxd4 $1 {The pawn is edible, despite the computer’s first thoughts.} (22… Qe7 $5 {is an interesting alternative with the idea that} 23. Bxd5 {can be met by} Nb4 {However White keeps something with} 24. Qd2 (24. Bxf7+ Qxf7 25. Qd2 Bxe4 26. Qxb4 Bxf3 27. gxf3 Qxf3 {looks pretty dangerous for White.}) 24… Bxd5 25. Nc5 Bxf3 26. Qxb4 ) 23. Nf6+ $1 {Uncompromising chess. The knight is of course taboo because of Qxg6+ due to the pin down the a2-g8 diagonal.} ({Instead} 23. Nxd4 Bxd4 $15 { would give Black a very pleasant position with his central active pieces.}) 23… Kh8 24. Nxd4 {Initially the computer likes White but gradually realises the power of Black’s two bishops.} (24. Nxd5 {must also be considered and, at this point, is probably obligatory.} Nxf3+ 25. Kh1 $1 (25. gxf3 Bxd5 26. Bxd5 Qh4 27. Qd2 Qg3+ 28. Kh1 Qxh3+ 29. Kg1 {and Black has at least a draw}) 25… Qh4 26. Qc3+ Nd4 (26… Bd4 {is also interesting.} 27. Qxf3 Qxh6 28. Qxf7 c5 29. Rae1 {is highly unclear.}) 27. Nxb6 b4 $1 {Now Black’s pressure down the h1-a8 diagonal gives White problems.} 28. Qd3 cxb6 29. Bxf7 Red8 30. Bc1 { looks rather perilous but it seems that White keeps equality:} Nc2 31. Qxg6 Rg8 32. Bxg8 Rxg8 33. Qh6+ Qxh6 34. Bxh6 Nxa1 35. Rxa1 Rxg2 {and the game looks to be petering out to a draw.}) 24… Nxf6 25. Nc6 Qh4 $1 {Those bishops are so strong that of course they shouldn’t be exchanged. Instead Svidler increases the pressure on White’s kingside.} 26. Nxb8 $4 {A horrible error. Kamsky had of course overlooked the power of Black’s next. However the position is already very unpleasant for White.} (26. Bxf7 {is necessary but horrible} Qxh6 27. Bxe8 Rxe8 {when the bishop pair easily trump the rook and pawn.}) (26. Bc1 Ra8 {leaves White all tied up.}) ({while} 26. Bd2 Re2 {allows Black a decisive kingside attack.}) 26… Re2 $3 {A wonderful shot and classic deflection.} ({ The immediate} 26… Qg3 {fails to} 27. Nc6) 27. Qc3 (27. Qxe2 Qg3 {is the very picturesque point and illustrates the power of the two bishops raking down towards the White king. White is a whole two rooks up but is incapable of defending against the mate on g2.}) 27… Rxf2 28. Nc6 Rxf1+ {With mate shortly. The game was not error free but very interesting and in the circumstances a wonderful game to witness. With this win with Black, Peter set himself up to go through to the later stages of the competition. In the quarter finals he defeated Judit Polgar, the strongest female player of all time. In the semis it was the turn of Ruslan Ponomariov, a former winner of the event to go down while in the final Svidler defeated his good friend Alexander Grischuk.} 0-1%%%pgn%%%
