Analysis of game one:Topalov versus Kamsky

Here is my analysis in html format if you desire it:

Topalov,Veselin - Kamsky,Gata [D87]
World Chess Challenge - candidates fina Sofia (1), 17.02.2009
[Deep Rybka 3]

Opening:Grunfeld Defense:Exchange variation 1.d4 Nf6 2.c4 The Queen's Gambit. 2...g6 3.Nc3 d5!? This move defines the defense being played by Kamsky,it is the Grunfeld Defense, a hypermodern opening, which allows White to create a large pawn center, which will be attacked by Black using piece play and pawns.I give this move a !?, because I find it surprising that Kamsky would chose this defense, as he has not had much success using it (especially in his match against Karpov in Elista). 4.cxd5 In his book "The Complete Grunfeld" GM Suetin calls this move, which initiates the "Exchange variation" of this opening, the "acid test" of the Grunfeld. 4...Nxd5 Regaining the pawn, however the knight has been deflected from the kingside for defensive purposes. 5.e4 The main continuation, attacking Kamksy's knight forcing the American to make a decision about the future of the knight in this game. 5...Nxc3 A move almost always played by Black in this position, forcing Topalov to accept an isolated a-pawn. 6.bxc3 Bg7 The main line,Kamsky intends to use this move in conjuntion with ...c5 in order to pressure Topalov's pawn center. 7.Bc4 Topalov develops his king's bishop before his king's knight, because he intends to develop the king knight to e2 to support his pawns. From c4 the white bishop attacks the f7-weakness in Kamsky's position. 7...c5 This pawn advance is the most popular move for White in this position. Kamsky pressures Topalov's pawn center even more.This pawn advance also allows him to develop his queen's knight behind his c-pawn at c6. 8.Ne2! Suetin gives this move a ! in his book "The Complete Grunfeld". Topalov reinforces his d and c-pawns, and prepares to castle on the kingside. 8...Nc6 The most often-played continuation. Kamsky catches up in minor piece development. He now has three of his pieces and pawns directed at Topalov's d-pawn. 9.Be3 A move almost always played in this position by the first player. Topalov completes the development of his minor pieces. A second piece of his is used to support his pawn center.Topalov plans to play Rc1, followed by d5. 9...0-0 The most often played move in this position for the player of the Black pieces. 10.0-0 Also the most popular continuation for White. 10...Na5 This idea has been rarely played by Black. Perhaps Kamsky wanted to avoid Topalov's preparations for the more critical variations of this line of play. GM Suetin, in regards to this move states, "This manoeuvre occurs much more frequently, after the preparatory 10...Bg4 11.f3,;the slight weakening of the g1-a7 diagonal is tactically important for Black's counterplay." [Analysis:Three moves are more often used in this position for Black:(a) 10...Qc7 ; (b) 10...Bg4 ; and (c) 10...cxd4 ] 11.Bd3 According to the chessbase online database,this is the main continuation in this position. Topalov tries to lure Kamsky into advancing the black c-pawn to c4. 11...b6 This pawn advance is the most often played response to White's last move. Kamsky advances the pawn to give his c-pawn support.This move also gives Kamsky the option of developing his light-squared bishop to b7 or even a6 in the future. 12.Qd2 Topalov develops his queen, which now forms a battery with his dark-squared bishop to pressure Kamsky's dark-squared bishop. In addition now both of Topalov's rooks are connected. [Analysis:According to the chessbase online database the move 12.Rc1 is the most often played continuation, with play usually following this course: 12...Qc7 13.Qd2 Rd8 14.Bh6 Bh8 15.Qe3 e6 16.e5 (16.Bg5 Rf8) 16...Bb7] 12...e5 Kamsky creates a triple attack against Topalov's d-pawn, threatening to win a pawn and a tempo after 13....cxd4 14.cxd4 exd4. [Analysis:The main line in this position continues: 12...Bb7 13.Bh6 cxd4 14.Bxg7 Kxg7 15.cxd4 e6 16.Rac1 Qe7 17.Qf4 Rac8 18.h4 Nc6 19.h5 e5] 13.Bh6 Topalov threatens to capture on g7, which would weaken Kamksy's king and also weaken his pawn center. [Analysis:According to the chessbase online database these other moves have also been tried in this position by White: 13.d5 ; 13.dxc5; 13.dxe5; 13.Rad1; Analysis:Deep Rybka 3: 13.Bg5 f6 14.Be3 f5 15.dxe5 Bxe5 16.f4 Bg7 17.e5 Be6=] 13...cxd4 [Analysis:According to the chessbase online database, these other moves have also been tried by Black in this position:(a) 13...exd4 14.cxd4 cxd4 15.Bxg7 Kxg7 =; and (b) 13...f6 ] 14.Bxg7N Analysis:According to the chessbase online database this capture is a theoretical novelty for the position. [Analysis:Prior to this game the only move white had used in this position was 14.cxd4 Galvan Huar...-Perez Garcia 2008, 1-0, Cheparinov-Kamsky 2008, 1-0, and Golichenko-Shishkin, 2008, 1-0] 14...Kxg7 15.cxd4 Forcing Kamsky to accept an isolated pawn on d4. 15...exd4 16.f4 Preparing the advance of his e-pawn to e5. [Analysis:Deep Rybka 3: 16.Qb2 Qf6 17.f4 Bb7 18.Nxd4 Rfd8 19.e5 Qe7 20.Be2 Nc6 21.Nb5 Ba6 22.a4 Bxb5 23.axb5 Nd4=] 16...f6 Contesting the advance of the white e-pawn.

Thoughts worth thinking about

"Our subconscious minds have no sense of humor, play no jokes and cannot tell the difference between reality and an imagined thought or image. What we continually think about eventually will manifest in our lives."-Sidney Madwed

Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia

A person's true wealth is the good he or she does in the world. - Mohammed

Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. -Albert Einstein

The best way to find yourself, is to lose yourself in the service of others. - Ghandi

The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller

Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns

Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures. -His Holiness The Dalai Lama

Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -

Milan Kundera, The Unbearable Lightness of Being

The worst sin towards our fellow creatures is not to hate them, but to be indifferent to them. That's the essence of inhumanity. -George Bernard Shaw

Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165

The hostile attitude of conquering nature ignores the basic interdependence of all things and events---that the world beyond the skin is actually an extension of our own bodies---and will end in destroying the very environment from which we emerge and upon which our whole life depends.
