Topalov – Shirov [D87]
2007 Corus Group A

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Bc4 c5 8.Ne2 Nc6 9.Be3 0–0 10.0–0 Bg4 11. f3 Na5 12. Bd3 cxd4 13. cxd4 Be6 14. d5 Bxa1 15. Qxa1 f6 16. Qd4 (We are all still in theories.) 16…Bf7 (16…Bd7 is also playable.) 17.Bh6 Re8 += (White has more than enough compensation for the exchange sacrifice due to Black’s slow development and weakness in the dark squares.) 18.Bb5 e5 19.Qf2 (Still in theories.) 19…Re7 20.f4 exf4 (White has to rely on the Bishop pair and Black’s Kingside weakness as compensation. This is truly fire versus fire!) 21.Qxf4 Qb6+ 22. Kh1 Bxd523. exd5 Qxb5 24. Qxf6 Qe8 = 25.Qd4 (White still maintains the initiatives with the extremely vulnerable Black King. This is actually a very difficult for Black to play, not because Black is losing, but because of the King safety issue. The mate threat is annoying and White has the powerful d pawn.) 25…Rd8 (It may come down to White playing Rf8 leading to 2 Rooks vs. Queen position. However, that would mean that White will no longer have any winning chances. Therefore, if Topalov wants to have have any winning chances, the Bishop must stay on the board to take advantage of the dark square weakness of Black.) 26.h3 Rf7 27.Rxf7 Qxf7 28.Qc3 = (Topalov and Shirov are among the best current players in this kind of position. It is ironic that Shirov is on the defensive side. Even though the d pawn is unprotected, Black cannot touch it because of double mate threat of g7 and backrank.) 28…b6 29.Ng3 (I’ve been analyzing this position and I cannot come up with any concrete plan for Black. Black has to be extremely patient and careful.) 29…Nb7 (Right after I said that Black had to be careful, Black made a bad move. Now 30.Ne4 and +-) 30.Ne4 Qe7 (The only defense. Now White can continue with 31.Nf6+ Kf7 32.Nxh7 +-) 31.Nf6+ Kf7 32.Nxh7 Kg8 33.Nf6+ Kf7 34.Ng4 (34…Rxd5 35.Qg7+ Ke6 36. Qxg6+ Kd7 37. Nf6+ Kc6 38. Nxd5+ Kxd5 +/-) 34…Kg8 35.Qd2 (Another interesting plan is 35.Bc1 then 36.Bb2 +-) 35…Re8 36.Qf4 +- Qd6 (37. Nf6+ Kf7 38. Nxe8+ Qxf4 39. Bxf4 Kxe8 40. Kg1 is an option. Keeping the Queen on the board with 37.Qf2 is another.) 37.Qf2 (Black does not seem to have any good defense. This will just be a slow torture.) 37…Qc5 (Black is desperately trying to trade the Queen. Even though that will lead to a very bad endgame, it is probably the best chance he got. Black is in deep trouble with the Queens on the board. Topalov can continue avoiding this trade with 38.Qf1) 38.Qg3 (This is less accurate than 38.Qf1.) 38…Qd4? (38…Qe7 would be Black’s best chance. Now, after 39.Kh2 Black is lost. Black cannot stop both threats of Qc7 and Nf6.) 39.Kh2! Nd8 40.Qd6 (It is over. Black has no more hope as Black cannot defend the g6 pawn and f6 square.) 40…Ne6 (41.Be3 would be the final blow. Black will lose the Knight and the position is completely lost.) 1-0

Carlsen – Anand [B90] 1/2

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e5 7.Nf3 Be7 8.Bc4 0–0 9.0–0 Be6 10.Bb3 Nc6 11.Bg5 Nd7 12.Bxe7 Qxe7 13.Nd5 Qd8 14.c3 Na5 15.Bc2 Nc4 16.b3 Na3 17.Ne3 (This is not a very agressive line for White. Black’s key weakness is rthe d6 pawn =/+=) 17…Nxc2 18.Qxc2 Rc8 19.Rd1 Rc6 20.Rac1 = b5 (White’s main focus will the the center and the d6 pawn.) 1/2 After the last 2 brutal consecutive games/losses, Magnus decided to take the day off to regroup. It is also convenient for Anand getting another Black out of the way. I understand their positions and they are probably right to do that. However, I am sure their fans are a little disappointed.
