Qb2 White decides to win back the pawn, but Black will take over the initiative - a clear example of a centre that's more of a target than a strength. 19... Nf6 20. Rxc8 Qxc8 21. Nd2? 21. Re1 Qc3 22. Qxc3 bxc3 23. Bxc3 Rc8 24. Ba5 Bd8 25. Bd2 is a slightly better version for White although here too Black has the advantage. 21... Qc3! 22. Qxc3 White must take. 22... bxc3 23. Bxc3 Rc8 24. Ba5 24. Bb2? Bb4 24. Rc1? Bb4 24... Bd8! This is what Carlsen had overlooked. 25. Bxd8 25. Bb4 Bb6 25... Rxd8 Now it's easy to see that White must lose a pawn. 26. Rd1 Rxd4 27. Nb3 Rd8 28. f3 Kf8 29.

1. d4 d5 2. c4 c6 3. Nc3 Nf6 4. Nf3 dxc4 5. a4 e6 6. e3 c5 Black has reached an important line from the Queen's Gambit Accepted - the one where White plays an early a2-a4. 7. Bxc4 Nc6 8.

This allows White to sacrifice an exchange in return for a strong, protected passed pawn, exactly the thing Anand had hoped to get! After 19... Bd6 20. Bxd6 (20. Be5!?) 20... Qxd6 21. Rfe1 White has a tiny advantage but it's not much. 20. Bxb8 Bxc3 21. Bxa7! 21. Bd6 Bxb2 22. Rab1 Bxd4 23. Bxf8 Kxf8 was what Anand intended. 21... Bxb2 22. Bc5 Bxa1 23.

1. d4 d5 2. c4 dxc4 We haven't seen the opening for a while on top level, and now suddenly we have the Queen's Gambit Accepted twice! 3. e4 e5 4. Nf3 exd4 5. Bxc4 Bb4+ 6. Nbd2 Nc6 7.

Rad1 Flear-Sadler, Isle of Man 1994 17... Bxa2 18. Rxa2 f5!? A committal move; it's logical to fix White's pawns on black squares but on the other hand e5 is now a protected passed pawn. It would be nice If Black could get his knight to e6. Apparently Ivanchuk didn't like 18... Be7 19. f5 O-O-O 20. b4 Rhe8 so much. 19. Nc5 Rb8 20. b4 c6 21. g4!? White continues energetically. 21...
