Oct-28-11  Crazychess1: What a grand draw! I was rooting for Anand the whole time!
Feb-12-12  reisena23: Only CG to provide us draws as good or even better than victories!
Feb-17-12  kia0708: Anand-Topalov 2005 was 23rd Century Chess.
I hope Anand-Gelfand won't be called 10th Century.
Feb-17-12  LaFreak III: 20.Rxd4 e5
21.Rxd5 Qc8
22.Nc4 exf4
23.Nb6 Qc6
24.Nd4 Qxb6
25.Rxd7..
I don't know if my line is correct, and I can see here that 26.Re1 is the next move.
Feb-26-13  voyager39: Topalov - Anand games can by themselves constitute a Chess Tactics Bible.
Sep-21-13  PawnJockey: I believe that 42: A7 is the way forward for white.

The threat of a pawn on the 7th would require careful and constant attention from black.

It would prove advantageous in the event that black actually manages to make good on his identical threat by queening the H pawn.

Oct-29-13  harshvk5: Am I the only one who doesn't get this game?
Wild tactics!
Jul-23-14  Garech: Gotta be one of the greatest draws of all time!

Excellent draws like this one deserve a 1-1

Mar-07-16  Alexandro: What would happen if Topalov hadn't decide checking perpetually, would he win or lose? Only a curiosity!!!
Jul-30-17  leroquentin: wow! the best game I ever saw!
Jul-30-17  ChessHigherCat: Topalov obviously played 16..f6 in preparation for Bf5, but I thought Bf5 is not that bad for white, because of 17. Qd3 Nf2?? 18. Qg6+ Ke7 19. Be3!!! threatening Bc5# and at least winning N on f2.

Anyway, I was floored when Anand played Bd3 and took away his only escape square because he had figured out how to get 3 pieces for the queen.

When these guys were in their prime they made Stockfish look like a clunky Olivetti word processor!

Sep-20-18  Boomie: <RandomVisitor: A final look at 42.a7!>

I doubt there will ever be a final word on this game, but 42. a7 looks golden. I took a swing at it 3 days after the game (Anand vs Topalov, 2005 (kibitz #19)). Today I'm using more powerful engines so it's worth trying again.

42. a7 Re2 43. Rd3 h2 44. Rh3+ Kg6 45. Nc4 (3.82/39 Stockfish 8/64)

It looks like the pieces were dropped on the board from a high place.

Although this is the kind of position where the engines shine, I don't fully trust the evals. However the eval climbs after each increase in depth. So we can cautiously say that white is winning. But remember that after the queen sac, the engines have black winning. Actually it's white who has all the winning chances. So even here, the engines might be fooled.

In any case, it was humans who had to play it. History's greatest tacticians could probably make it to the full point. And these two guys certainly qualify for that club.

The continuation is a challenge to understanding. What do these moves mean?

45...f5 46. Kb2 (This is the only winning move according the The Fish. How would a human find it?) 46...Re4 47. Nd2 (Again the only winning move.) 47...Ra4 48. Rxh2 (4.85/36)

Soon black will have to give up the exchange for the a7 pawn. Else the queen is condemned to a blockading role.

  plang: A few months earlier at Linares Topalov had played 12..d5 against Anand and White had gone on to win; here he varied with 12..Bd7 which was no surprise to Anand as Cheparinov had recently played the move. In that game against Rodriguez at Dos Hermanas Cheparinov had played 16..Qa5; 16..f6 was Topalov's improvement.

Anand after 17 Bd3!?:
"Since Black's threats are quite serious, White must take drastic action to eliminate Black's knight on e4. I felt that the three pieces should be reasonable compensation for the queen."

Anand was critical of 26..h5? recommending 26..Bxg6 27 Nxg6..Rh7 28 Nh4..Qd7 29 h3..h5 with advantage to Black. In this fascinating back and forth game White's last chance to play for a win was 47 Bb6!..f4 48 a7..Kg6 49 Bc5.
