1. e4 e6 Again the French Defence.
2. d4 d5 3. Nd2 And again the Tarrasch Variation.

Middelhoven-Marcus, Haarlem 2001
13... Qb6 14. Bb3 a5 All still preparation for Kamsky, while Topalov had just a bit of time already.
15. Be3 Bc5 Kamsky was still playing fast here.
16. Rad1 In this specific position, this natural move involves a pawn sacrifice.
16... a4 Topalov spent a short while thinking here - perhaps he needed to double check what he was doing?
17. Bc2 And now... to take or not to take?
17... Qxb2 Kamsky goes for it. Of course it's the principled move - if Black doesn't take, White definitely has a small and solid advantage - not something you want in a must-win situation. Big tension on the board right out of the opening!
18. Bg5 18. Bh6 is spectacular but not good: 18... Bxd4 19. Qg3 Nh5 20. Qd3 f5 21. Qxd4 gxh6
18. Bd3 Qxc3 19. Qxb7 Rab8 20. Qf3 Rb2 is now what you want either.
18... Nd5 18... Be7!? 19. Rb1 Qa3 (19... Qxa2 20. Rxb7 Rad8 21. Qh3 g6 22. Qh4 Kg7 23. Ra7 looks good for White)
20. Rxb7 Rad8 21. Qh3 g6 22. Qf3 Nd5 23. Bh6 Rfe8 was perhaps possible.
19. c4! White needs to play actively, of course.
19... Bxd4! 20. Qd3! f5 The players are both following Rybka's recommendations - quite suspicious. ;-)
21. Qxd4 Qxc2 22. cxd5 Qxa2 Part of the smoke has cleared, and what is left is an opposite-coloured bishops position with great activity for White, but material and an advanced passed pawn for Black. A very exciting game so far! Both players have about an hour left on the clock, and they'll need it to calculate, that's for sure.
23. Qb6 a3! Still following the computer's recommendation and again the principled move, of course. Passed pawns must be pushed! (Yermolinsky).
24. Be7 Played relatively fast by Topalov. He's done that more often in the match: keeping the pressure on Kamsky by playing fast.
24. dxe6 Bc6 25. e7 Rfe8 26. Rd8 Qf7 27. Bc1 a2 28. Bb2 is an original type of position where both bishops control the promoting square of a pawn that has reached the seventh rank! Black is still a pawn up, but this might well be a draw.
24... Rfe8 25. Qd6 Topalov spent about thirteen minutes on this move - he has about 40 left. Kamsky has been thinking for over 20 minutes now.
25... Ba4?! Played after a half-an-hour think. Kamsky's second Emil Sutovsky called it "probably the safest option, but perhaps not enough to play for a win."
The computer wants to play 25... Bc8! 26. dxe6 (interesting is 26. Qc7!? preparing d5-d6)
26... Qc4! which looks very dangerous but after e.g. 27. Rc1 Qa4 it's not easy to see a continuation for White.
26. Qxe6+ Kh8 27. Ra1 Qc4 Topalov has 32 minutes left here, Kamsky a bit less than eight.
28. Rec1?! After a twelve-minute think.
28... Bc2! 29. Qd7?! Played quickly again - Topalov again prefers to put pressure on the opponent instead of calculating everything till the end.
29... a2! The computer likes Black again.
30. d6 Almost instantly played - Topalov is taking risks.
30... b5! 31. Qb7 Reb8? 31... b4! 32. d7 Reb8 33. d8=Q+ Rxd8 34. Qxb4 Qxb4 35. Bxb4 Bb1 would have won for Black!
32. Qc7! A great move. Kamsky has two minutes left.
32... Rc8? The final mistake. Topalov's strategy has worked yet again, and this time it has decided the match!
Necessary was 32... Bd3!! 33. Rxc4 bxc4 and because of the mating threat White has to go for 34. Qxb8+ Rxb8 35. f3 Rb1+ 36. Kf2 Rxa1 37. d7 h5 38. d8=Q+ Kh7 39. Bf6!! gxf6 40. Qe7+ draw!
33. Qxc4 Rxc4 34. d7 Bb1 34... Rd4 35. d8=Q+ Rdxd8 36. Bxd8 Bb3 37. Be7 should be winning too.
35. Rd1 Kg8 36. d8=Q+ Rxd8 37. Bxd8 Bc2 38. Rdc1 b4 38... Bb3 39. Rxc4 Bxc4 40. Be7
39. Rxa2 b3 40. Ra8 Kf7 41. Rb8 End of the timetrouble for Kamsky. He's lost, but can't make himself to resign yet.
41... Ke6 42. Re1+ Kd5 43. Be7 Ra4 44. Bf8 Ra7 45. h4 Kamsky resigned. It's Topalov playing Anand - the second World Championship Match for Bulgarian, and so it will be the world's number one against the world champion!
