ch-USA Saint Louis USA (5), 18.05.2010
[GM Lubomir Kavalek/Huffington Post]

1.e4 e5 2.Nf3 Nc6 3.Bb5 The powerful Spanish Opening is more than 500 years old. It is often associated with Ruy Lopez, a priest who served at the court of the Spanish king, Philip II, and analyzed it in his book in 1561. But it already appeared in the oldest surviving chess book, "Repeticion de amores e arte de axedrez con cliuegos de partido," written by another Spaniard, Luiz Ramirez Lucena, in 1497. Lucena suggested the defense 3...Nge7 for black.

3...Bc5
The Classical variation was favored by many champions and world-class players. Adolf Anderssen, Paul Morphy and William Steinitz played it in the 19th century. Jose Raul Capablanca, Alexander Alekhine, Boris Spassky and Bobby Fischer, and more recently Vishy Anand and Veselin Topalov also tried it. Even Kamsky used it with the black pieces.

4.0-0 Nd4
[Christiansen avoids 4...Nf6 5.Nxe5 Nxe5 6.d4 Nxe4 7.Qe2 Qe7 8.Qxe4 Nc6 9.Qxe7+ Bxe7 10.c3 and white gets more space and a slightly better endgame. Kamsky, a feared, brilliant endgame technician, would love that.]

5.Ba4
[5.Nxd4 is played more often, but after 5...Bxd4 6.c3 Bb6 7.d4 c6 8.Ba4 d6 Black has good chances to equalize.]

5...Nxf3+ 6.Qxf3 Ne7
[Christiansen strives for a good counterplay, not blocking his f-pawn. After 6...Nf6 7.d3 0-0 8.Nc3 white has a better grip in the center. Offering a queen exchange 6...Qf6 is a good alternative.]

7.Qc3!?N
An aggressive Queen-shuffling maneuver is a remarkable novelty. White lures the black bishop to d4, where it can be soon attacked. It allows Kamsky to build a pawn center quickly. Slower, steady developing moves may not do the job. For example, in the game Reti-Spielmann, Budapest 1913, White came under a furious attack after [7.d3 0-0 8.Be3 Bb6 9.Nc3 d6 10.Rad1 f5 11.Qh5 f4 12.Bxb6 axb6 13.Bb3+ Kh8 14.d4 Ng6 15.Rd2 f3 16.g3 Nf4 17.gxf4 Rxf4 and white resigned since after (17...Rxf4 18.h3 [defending against Bc8-g4] 18...g6 19.Qh6 Rh4 20.Qe3 Rxh3 black has a mating attack.) ]

7...Bd4 8.Qg3 Ng6 9.c3 Bb6 10.d4!?
A daring pawn sacrifice. White has to act quickly to dominate the center, bring more pieces into play and put pressure on Black.

10...0-0
[It is safe to assume that after 10...exd4 Kamsky was going to continue with 11.f4!? as in the game, when the attempt to exchange the Queens with 11...Qh4 fails to 12.Qxh4 Nxh4 13.f5 threatening to win the knight with 14.g3.]

11.f4!?
[Kamsky continues to play sharply. He did not bother calculating 11.dxe5 Qe7 12.Bf4 d6! and Black wins the pawn back since after 13.exd6 Qxe4 White loses a piece.]

11...exf4?!
[Leaving White with a strong pawn center. Accepting the pawn with 11...exd4 is unclear, but worth a try. After 12.f5!? Qf6 (or 12...dxc3+ 13.Kh1 Bd4 14.Nxc3 Be5 15.Qf2 Ne7 16.Bf4 ) 13.Kh1 h6 14.cxd4 Bxd4 15.Nc3 White has a good compensation.]

12.Bxf4 Nxf4 13.Qxf4 d6 14.Nd2 Be6 15.Kh1 c6 16.Nf3 h6
Defending against 17.Ng5, but the move weakens the diagonal b1-h7 and Kamsky finds a way to open it up.

17.Bc2 Qd7 18.e5!? dxe5?!
[Christiansen reacts nervously, surrendering a nice square on e5. But after 18...d5 19.Nh4 the white pieces swarm the black King, for example 19...c5 (19...g5? 20.Qf6 gxh4 21.Qxh6 f5 22.exf6 Bc7 23.Qg6+ Kh8 24.Rf5! Bxf5 25.Bxf5 Qf7 26.Qh6+ Kg8 27.Be6 Qxe6 28.Qg7# ; 19...Bd8 20.Ng6 Re8 21.Qg3+/- ) 20.Qg3 cxd4 21.Qd3 f5 22.g4! with a powerful attack.; Also after 18...Bc7 19.Qe4 g6 20.Qf4 Kg7 21.Rae1 White has a strong pull.]

19.Nxe5 Qd6 20.Qg3 f5?!
[A radical solution to slow White's surge on the kingside, but it only pours more oil on the fire. Either 20...Rad8 ; or 20...Bc7 were preferable.]

21.Rae1 Bc7
[After 21...Rad8 White has a pinning combination 22.Ng6! Qxg3 23.hxg3 Rf6 24.Rxe6 Rxe6 25.Bb3 and should win.]

22.Qh3!
Forcing the weakening of the diagonal b1-h7.

22...f4 23.Qd3 Bf5 24.Bb3+ Kh7 25.Qd2 g5
With a pawn chain resembling the King's Gambit, Christiansen hopes to survive. But Kamsky finds an ingenious way to storm Black's rampart.

26.g4!
Winning the battle of the light squares.

26...Bc8
[Not finding another suitable square, the Bishop slides back home. After 26...Bg6 27.Nxg6 Kxg6 (27...Qxg6 28.Bc2 ) 28.Re6+ Black loses the Queen.; And 26...fxg3 is unplayable because of 27.Rxf5 Rxf5 28.Bc2 Raf8 29.Bxf5+ Rxf5 30.Qd3 Qe6 31.Rf1 winning material.; 26...Be6 27.Qd3+ ; 26...Bd7 27.Qd3+ Kg7 28.Bc2 wins for White]

27.Qd3+ Kg7 28.Bc2
The battery of the Queen and Bishop on the diagonal b1-h7 is deadly.

28...Rh8 29.Ng6
Threatening both 30.Nxh8 and 30.Re7+.

29...Bxg4?!
[Leads to a pretty finish, but Black didn't have many choices. After 29...Be6 30.Nxh8 Bd5+ 31.Kg1 Rxh8 32.Bb3 White should win anyway.]

30.Re7+ Kf6
[On 30...Kg8 31.Bb3+ wins.]

31.Rxc7 Rhg8
[After 31...Qxc7 32.Nxh8 Rxh8 33.Qg6+ Ke7 34.Qg7+ wins.]

32.Ne5
[After 32.Ne5 Qxc7 33.Nxg4+ Ke7 34.Qh7+ Kd6 35.Qxh6+ Kd7 36.Bf5+ Kd8 37.Re1 wins.] 1-0
