  Ron: <jeremy24: Is this endgame truly a win for white?>

Yes, both sides have same color bishops while White has a two pawn advantage.

This is an excellent game by Topalov, his style of play at its best.

Nov-14-07  aazqua: Of course that doesn't prove it's a win at all. After c3 g4 c2 bb2 bd2 h4 c1 bc1 bc1, white has 3 connectors half way down the wing but is about to lost his qr pawn leaving black free to race for the goal. I guess the three pawns are far enough advanced that they can be forced through before the black pawn. >

Nov-14-07  ikipemiko: Truely a gem produced by Topa!
I wonder where did Nisi go wrong?
Nov-14-07  chessmoron: 45...f5+! would have made it a draw.
Nov-14-07  ikipemiko: 45 ..f5 will lose quicker
Nov-14-07  Mateinonenik: <45...f5+! would have made it a draw.>No wonder you call yourself "<chessMORON>"
Nov-14-07  fromoort: Isn't 45...f5+ illegal?
Nov-14-07  ivan999: its not illegal but losess almost immediately.
Nov-14-07  chessmoron: YiKES! 42...f5+!
Nov-14-07  efrain chavez: White is two pawns up indeed, but its also about to lose the bishop for the c black pawn. After loosing the bishop, the black "a" pawn promotes in 8 moves. I do not see how the three white king side pawns can combine to do so against the black bishop in c3 and the black king in f8 in less than 8 moves... As black I would have surely played on a few more moves. I think it IS a draw.
Nov-14-07  ivan999: you must be kidding efrain chavez, the white bishop can stop the pawn from promoting.
Nov-14-07  Alphastar: Actually white will promote first: 51. ..c3 52. f5! c2 53. Bg5 with f6-f7+ and Bh6+ followed by queening,

or 52. ..Bd2 53. Be7! and again f6-f7-f8 is killing for black.

Nov-14-07  ivan999: Analysis by Fritz 9: final position

1. (2.71): 1...Bxa5 2.f5 Be1 3.Bg7 Bh4 4.g4 a5 5.Bc3 Be7 6.g5 2. (3.42): 1...Bg3 2.f5
3. (3.15): 1...Bb4 2.f5 Bxa5 3.g4 Bd2 4.h4 c3
4. (3.15): 1...Bd2 2.f5 Bxa5 3.g4 Bd2 4.h4 c3
5. (3.15): 1...Bf2 2.f5

Nov-14-07  efrain chavez: 52...c3 54 f5 Bd2 55 g4 c2 56 Bb2 c1(Q) 57 Bxc1 Bxc1 All that is forced. Now white has no bishop to stop the black "a" pawn. For instances 58 g5 Bd2 59 f6 Bxa5 60 Kf5 Bc6 61 g6 a5 and?? black is winning here. I must be missing something. Mr Fritz does not consider 52...c3 at all, why?
Nov-14-07  ivan999: Analysis by Fritz 9:

1. (8.34): 1...c3 2.f5 c2 3.Bg5 Bh4 4.Bc1 Kh8 5.f6 Bxf6 6.Kxf6 Kg8 7.g4 Kf8 8.Ba3+ Kg8 9.g5 c1Q

Nov-14-07  ivan999: In your line after bd2 white has bishop e7 and mate is coming. Black has to sacriface its bishop to stop it.
Nov-14-07  chessmoron: <ivan999> Forget him. What does 42...f5+ evaluate?

Nov-14-07  ivan999: strangely, it seems like f5 is black's most accurate move. 1. ² (0.47): 1...f5+ 2.Nxf5 c3 3.Bxc3 Rxc3 4.Ne7 Rc5 5.f5 Rd8 6.g3 Rxa5 7.Qf7 Ra4+ 8.Kh5 Bf2 9.Nc6
Nov-15-07  virginmind: yeah, 42...f5 is very hard to see/accept as good for a normal player, because it immediately losses a pawn and a normal player is not fritz 9 to forsee that continuation in your line. or maybe nisi did notice it and still thought the game is lost?
Nov-15-07  whiteshark: So, where went Nisipeanu wrong ?
Nov-15-07  ivan999: If I am not wrong, Nisi was in a time trouble so seeing f5 might have been hard.
Nov-15-07  whiteshark: Grabbing the ♙e4 in his move 26 was a superior mistake by black as it opens the e-file for ♖e1, throwing away 2 tempi and brings the black ♕ in danger.

Instead the counter-attack <26...♖d3> was a better idea and should grant for rather equal chances.

Interestingly, Speelman doesn't seem to know the time control used in this tourney (120 minutes to finish +30s/move), as he writes:

<40 Kg3 Rd3+ Reaching the time control <!> in a real mess. It's more than possible that Topalov wasn't certain how many moves had been played after such excitement but in any case his 41st move was a mistake.>

Oct-01-08  Poisonpawns: Topalov didn't even have to take this to an endgame:His missed some clear tactical shots. 32 N4f5! Qd7 33 Bxg7+ Nxg7 34 Qf6 Rg8 35 Rad1 White should win quickly.

36 Ng3! Nxg3 37 fxg3!Rf1 38 Qe4
