The report of the most brilliant games of the tenth round is proposed to the attention of the readers by GM Sergey Zagrebelny
Sutovsky,Emil (2665 Israel) - Kamsky,Gata (2705 USA)
1.e4 c5 2.Nf3 e6 3.Nc3 a6 4.d4 cxd4 5.Nxd4 b5 6.Bd3 Qb6 7.Nf3 Nc6 8.0–0 Nge7 9.Be3 Qc7? A very unfortunate novelty.
10.Bxb5. It seems Kamsky just blundered this typical Sicilian blow. 10…Rb8 The knight is taboo, of course: 10...axb5? 11.Nxb5 Qb8 12.Nd6+ Kd8 13.Nxf7+. 11.Bxc6. 11.Bc4!? is also good, because after 11…Rxb2? 12.Bb3 the rook is trapped. 11...Nxc6 12.b3 Bb7.
13.Nd5!? Sutovsky is not interested in pawns when he can deliver a tactical blow. 13…exd5 14.exd5 Nd8 15.Re1 15...Ne6. 15...Be7 is not good due to 16.Ba7 Ra8 17.d6. 16.Qd2 Bb4 17.Qxb4 Bxd5 18.Qd2 18...Bxf3
19.Bf4!+- d6. 19...Qc6 20.Bxb8 Bxg2 21.Qd6 leads to a hopeless position. 20.gxf3. Weaker is 20.Bxd6? Rd8 21.Bxc7 Rxd2 22.gxf3 0–0, and Black has drawing chances. 20...Rd8 21.Rad1 0–0 22.Bxd6 Qc8 23.f4? Emil loses his focus. The natural 23.c4 is clearly stronger.
23...Nc5? Kamsky misses an excellent chance. He could sacrifice a knight by 23...Ng5!, and after 24.Re3 (24.fxg5 Qg4+ 25.Kf1 Qh3+ leads to a perpetual) 24...Qg4+ 25.Kf1 Nf3 26.Qd5 Rxd6 27.Qxd6 Nxh2+ 28.Ke1 Nf3+ 29.Ke2 Nd4+ 30.Kd2 Nf5 31.Qd5 Nxe3 32.fxe3 Black has very good drawing chances. 24.Qc3 Rfe8 25.Rxe8+ xe8 26.f3 Rd8 27.Rd5 Qe6 28.Qxc5 Rc8 29.Qxc8+ Qxc8 30.Be7 Black resigns.
Shirov,Alexei (2749 Spain) - Jobava,Baadur (2710 Georgia)
1.e4 c6 2.d4 d5 3.e5 Bf5 4.Nf3 e6 5.Be2 Ne7 6.0–0 Bg6 7.Nbd2 Nf5 8.g4 Ne7 9.Nh4 c5 10.c3.
10...Nbc6. Jobava moved another knight to c6 against Lahno in Wijk-aan-Zee-2006.11.Nb3 c4 12.Nd2 h5 13.g5 Nf5 14.Ndf3 Be7 15.Kh1 b5. Probably 15...Nxh4 16.Nxh4 Be4+ 17.f3 Bh7 should be preferred. 16.Nxf5 Bxf5 $272 17.Nh4 Be4+ 18.f3 Bh7 19.Rg1 b4
Black's position looks promising, and Shirov finds the way to complicate things. 20.g6!? Bxh4 21.gxh7 g6. Perhaps Black should have played 21...Rxh7!? 22.cxb4 (22.Qa4?! Qd7 23.cxb4? Nxd4) 22...Qb6.22.cxb4 Qb6 23.Be3 Nxe5 24.b3. White tries to open as many files as possible. 24…cxb3?! 25.axb3 Nd7 26.b5 Rxh7 27.Ra6 Qb7 28.Qc2 Nb8.
29.Rxg6!! Fire on board alert!29…fxg6 30.Rxe6+ Kd8. White wins after 30...Re7 31.Qxg6+ Kd8 32.Bg5 Bxg5 33.Qxg5 Qd7 34.Rxe7 Qxe7 35.Qxd5+ Kc8 36.Bc4!, too. 31.Qxg6 Qf7 32.Bg5+ Bxg5? Better is 32...Kc7 33.Qc2+ Kb7 34.Rf6 Qg8, although Black's position here is also quite bad. 33.Qxg5+ Kc8 34.Qxd5 Rg7
35.Bc4! A deadly thrust!35…Qg8 36.Rc6+ Nxc6 37.Qxc6+ Kb8 38.Qd6+ Kc8 39.Bxg8 Rxg8 40.d5
40...h4 41.Qc6+ Kb8 42.d6 Rc8 43.Qd5 h3 44.Kg1. Black resigns.
Sjugirov,Sanan (2627 Russia-4) - Carlsen,Magnus (2826 Norway)
1.e4 c6 2.d4 d5 3.e5 Bf5 4.Nf3 e6 5.Be2 Bb4+ 6.Nbd2 Nd7 7.0–0 Ba5 8.Nb3 Bc7.
9.Ne1. A new move – White wants to support his e5-pawn by f2-f4. 9...f6 10.Bh5+ g6 11.Be2 g5?! White threatened 12.g4, but the best defense against it is a standard 11...h5, and then 12.f4 h4, etc. 12.Bd3 Bg6. Too bad for Black is 12...Bxd3 13.Nxd3 fxe5? 14.Qh5+. 13.exf6 Qxf6 14.Qg4 h6.
15.f4! White demonstrates that 11…g5 was premature. 15…Bxd3 16.Nxd3 0–0–0 17.Bd2. Of course, White does not overlook 17.fxg5? Bxh2+ 18.Kxh2 Qxf1. 17...Qg6 18.fxg5.
18...Ngf6? Carlsen doesn't want to suffer for hours, otherwise he would have played 18...hxg5 19.h3 Ngf6 20.Qxg5 Rdg8 21.Qxg6 Rxg6. 19.Rxf6!+- Bxh2+ 20.Kh1 Nxf6 21.Qxe6+ Kb8 22.gxf6 Bc7 23.Ne5 Qxc2 24.f7 Rhf8 25.Bb4. Black resigns.
Movsesian,Sergei (Slovakia 2723) - Topalov,Veselin (2803 Bulgaria)
1.e4 c5 2.Nf3 d6 3.Bb5+ Nd7 4.d4 cxd4 5.Qxd4 a6 6.Bxd7+ Bxd7 7.Bg5 Rc8 8.Nc3 h6 9.Bh4 e5 10.Qd3 g5 11.Bg3 Nf6 12.h4 g4 13.Nd2 b5.
Black obtained a very playable position that suits Topalov's style perfectly. 14.a3 Be6 15.0–0 Be7 16.Rfd1 Qb6 17.Nf1 Rc4 18.Nd2 Rd4 19.Qe3 Qc6 20.Re1
20...Bd8! Black sensibly brings his bishop to a better diagonal. 21.Nb3 Rc4 More accurate is 21...Bb6 22.Qe2 Nh5. 22.Rad1 Bb6 23.Qd3 Rxc3. A standard but very demanding exchange sacrifice. On 23...Ke7 Topalov probably disliked 24.Nd5+ Bxd5 25.exd5.
24.bxc3 Ke7 25.Qd2 Rg8 26.Kh2 Rg6.
27.c4! A timely sacrifice of a worthless pawn. 27…bxc4? Topalov loses his composure! After 27...Bxc4 28.Na5 Bxa5 29.Qxa5 Nxe4 30.Rxe4 Qxe4 31.Qc7+ Kf8 32.Rxd6 Re6 the position is equal. 28.Na5 Qc7 29.Nb7! Ne8. 29...Qxb7? is bad due to 30.Qxd6+ Ke8 31.Rb1 Nd7 32.h5 Rg5 33.Bh4. 30.Rb1 a5. On 30...c3 White gets a big advantage by the energetic 31.Qd3 Rf6 32.Nxd6! Nxd6 33.Bxe5 Rxf2 34.Rxb6! Qxb6 35.Bd4 Qc7 36.Bxf2 Nxe4+ 37.Bg3. 31.h5.
31...Rg5. Or 31...Rg8 32.Bh4+ f6 33.c3 Qxb7 34.Qe3 Bxe3 35.Rxb7+ Bd7 36.Rxe3. 32.Bh4 f6 33.Bxg5 fxg5 34.c3+- Ba7?! 35.Red1 Bd7 36.Qd5 g3+ 37.Kxg3 Black resigns.
