2.5-2.5. The parity continues

The 5th game of the match went slightly better for White; after the opening, Carlsen tried to solve his problems in as certain way as possible, while Anand, surprisingly for many spectators and commentators, decided not to persist. Probably his decision was in fact well justified, which is for the readers to judge from the annotations.

ANAND - CARLSEN
Queen's Indian Defence

1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.g3 Bb4+ 5.Bd2 Be7 6.Nc3 Bb7 7.Bg2 c6!?

This interesting move has been introduced into practice by Sergey Tiviakov in the early 1990's. Paradoxically, Black locks his Queen's Indian bishop for a while, intending to recapture with the c-pawn after d7-d5 and to keep his pawn structure healthy. The 'classical' approach 7...Ne4?! doesn't make sense here, leading to a well-known theoretical position with an extra tempo for White; after 8.d5! White is clearly better.
8.e4 d5 9.exd5 cxd5 10.Ne5 0–0 11.0–0 Nc6 12.cxd5!? The alternative 12. Qa4 can be met by the precise 12...Qe8! (12... Rc8?! 13.cxd5 exd5 14. Rfe1 with advantage for White, Z.Almasi - Breder, Germany 2003) 13. cxd5 Nxe5 14. Qxe8 Nf3+! 15. Bxf3 Rfxe8 with balanced play.
12...Nxe5.

13.d6! A novelty by Anand who wasn't surprised at all by Carlsen's opening choise. 'I'd looked at this long back and I thought this should be better for White' - Anand. 13.dxe5?! Nxd5 is equal (Komljenovic - Palac, Sibenik 2010).
13...Nc6! (13...Bxg2?! 14.dxe7 Qxe7 15.dxe5 Bxf1 16.exf6 Qxf6 17.Qxf1 leaves White with slight material advantage) 14.dxe7 Qxe7 15.Bg5 h6 16.d5! Na5 (16...Rad8?! 17.Bxf6 Qxf6 18.dxc6! Rxd1 19.Rfxd1 Bc8 20.a4!? can be very dangerous for Black due to White's mighty passed pawn) 17.Bxf6 Qxf6 18.dxe6.

18...Qxe6. A wise and cold-blooded decision. Black is a bit worse for the moment, but he has every reason to hope to equalise gradually. 18...Bxg2 19. exf7+ Qxf7 20. Kxg2 Nc4, and 18... fxe6 were the strange alternatives suggested by engines, but in fact a very few strong players (unless being able to follow computer evaluation during the game) would really consider either giving up a pawn for dubious compensation, or creating a permanent weakness at e6 and exposing the king.
19.Re1 Qf6 20.Nd5! Bxd5. The d5-knight is too strong to be tolerated. Anand's preparation ended around here; at the press conference, he showed the following line: 20...Qxb2?! 21.Re2 Qa3 22.Re3! Qb2 23.Rb1 Qxa2 24.Ra1 Qb2 (24...Qc4! 25.Rxa5 bxa5 26.Ne7+ is the slightly improved version for Black) 25.Rxa5! bxa5 26.Rb3, getting 2 light pieces for a rook and an obvious advantage.
21.Bxd5 Rad8 22.Qf3. Setting up a hard dilemma for Black.

22...Qxb2!? Carlsen's plan is to eliminate all the queenside pawns, as eventually happened in the game. 22...Qxf3 is a sort of long-term advantage for White known since the Capablanca textbook: White is going to be pressing as long as he keeps a bishop against a knight, either with the rooks or not. The problem for Black is that the position is too open, the pawns are at both sides, and his knight has no strongholds.
23.Rad1! Qf6. This is the logical continuation of the previous move; the threats were both Bxf7+ and Re7. Of course, the resulting endgame is more pleasant for White, but for equality Black basically needs to exchange the only remaining pawn on the queenside, as any kinds of endgames 3 vs 3 (or a rook ending 3 vs 2) are drawn.
23...Rd7 would have probably been met with 24.Qf5 Rc7 25.Be4 g6 26.Qf4!, regaining the pawn and keeping the initiative, while 23...Rd6? loses due to 24.Bxf7+! Rxf7 25.Re8+ Kh7 26.Qxf7 Rxd1+ 27.Kg2. 'The problem for Black is 27...Rd6 28. Qf5+ Rg6 29. Re6, and we both made the same mistake that Qc1+ and Qg5 was possible and then realised that Qc1 is no longer a check' - Anand.
24.Qxf6 gxf6 25.Re7 (White regains a pawn, threatening both Rxa7 and Rxf7) 25...Kg7.

26.Rxa7. This decision by Anand wasn't understood by many chess fans, including renowned GMs: the a5-knight is too passive and White isn't obliged to hurry up. The challenger had seen both 26.Rc7 and 26.Kg2 as the alternatives but for some reason went for the most straightforward way, allowing Magnus to escape quickly. To be honest, I'm quite sure that the World Champion would have held the position anyway (the defence isn't that difficult for a 2850+); probably Anand was of the same opinion and decided to save his energy. On the other hand, Carlsen himself would probably have been more resourceful in a position like this. Let's look at the alternatives:
26. Rc7 (trying to cut off the knight) 26...a6! 27. Rd3 (27.Kg2 Kh8!, avoiding Bxf7 and intending ...b5 or Rd6 is quite easy for Black) 26...Rc8 (or simply 26...Kh8) 28. Rdc3 Rcd8, as suggested by Carlsen, is quite drawish indeed;
26. Kg2! is a bit more cunning. After 26... Nc6 27. Rc7 Ne5 28. Rxa7 Rd6 29.Bb3 Rxd1 30. Bxd1 Rd8 31. Bb3 Rd2 'with about enough counterplay' (Carlsen) the situation isn't entirely clear yet and White can play on, so maybe Magnus would have to find 26...a6! with the main idea of 27.Bxf7! (27.Rc7 Kh8 transposes to the 26.Rc7 line) 27...Nc6!! (27...Rxd1 28.Bh5+ is in White's favour) 28.Rxd8 Nxe7 29.Rxf8 Kxf8 30.Bb3 Nc6! and Nd4=.

26...Nc6! 27.Rb7. The last try would have been 27.Ra4, but after 27...Rd6!? 28.Bf3 Rxd1+ 29.Bxd1 Rd8 Black puts his knight on d4 and holds the game. Nevertheless, Magnus would probably have tried this as well, had he been White.
27...Nb4 28.Bb3 Rxd1+ 29.Bxd1 Nxa2.

Black has reached his goal. The engines continue to talk about +0.6 and so on, but in fact the position is just drawn. Let me give an example of the ideal version for White:



Black's setup looks ridiculous (he has to strive hard for it!), but White doesn't seem able to make any sufficient progress even here.

30.Rxb6 Nc3 31.Bf3 f5 (avoiding any questions) 32.Kg2 Rd8 33.Rc6 Ne4 34.Bxe4 (the last dozen of the moves was blitzed out by the opponents) 34...fxe4 35.Rc4 f5 36.g4 Rd2 37.gxf5 e3 38.Re4 Rxf2+ 39.Kg3 Rxf5 1/2

The score is equal: 2.5 - 2.5. The 6th game will start today, on November 15, at 12:00 GMT, as usual.

This is funny how you

This is funny how you describe the common overreaction to Anand's 26th move. Isn't it a bit too understated? Your own co-editor Mikhail Golubev called him an amateur who is happy to draw a grandmaster at first opportunity.

If people didn't overreact

If people didn't overreact from time to time they'd be robots, not humans. It happens.
Yakov: thanks.
