  Oxspawn: I got it right. Amazing. Never would happen in a game, where I would play my 'good' move and then watch the roof fall in.

  perfidious: My first thought was also 44.b7 Nxb7 45.c7, leaving a tough row to hoe.

The interpolation of 44.Bb3 puts things aright and leaves Black without resource.

  OhioChessFan: The theme is the overworked piece. The d5 Bishop is necessary to stop the advance of the Pawns, but unfortunately is on the same diagonal as the Black King. Bb3 puts the question to the Bishop and he can't answer all his obligations.
Nov-28-12  Doktorn: This kinda jumped right at me. End games is very intuitive for me. I first looked at 44. b7 but saw that 44. ... Nxb7 45. cxb7 Bxb7 at least secures a draw. So then I tried to open the way for the pawns and 44. Bb3 was obvious to me.
Nov-28-12  prbprb2: Why does black allow white to recapture the pawn so easily on move 23? I can't tell what is going on there. Does he need to secure the d file?

Me too. Usually by Wednesdays I need some time, but this one I could have blitzed. There are some Wednesdays with tactical shots everyone else sees at once that are majorly hard for me, but the endgame puzzles are really easy. I assume GM's find all types of positions that intuitive.

Nov-28-12  Razgriz: Well pushing the pawns was the general plan but blacks dark squared bishop made it difficult. Okay sacrifice something to take it out.
Nov-28-12  dumbgai: I had something similar in one of my own games (position after black's 41st move):

I found 42. Bc4 and soon won.

Nov-28-12  absolutezero7: This one didn't seem so easy to me.
Nov-28-12  Bengambit: Ok,44.Bb3 is cool. The b6 to b7 then to b8 pawn cannot be caught.
Nov-28-12  lost in space: Got that one quicky
Nov-28-12  LIFE Master AJ: I was quite puzzled at first. Neither Pawn push looked good, the immediate b7, is foiled by NxP! when White loses both of his remaining Pawns.

Finally, it occurred to me that Bb3! was good, Black cannot take ... but apparently there was nothing better ... as White plays b6-b7, getting a new Queen.

  Jimfromprovidence: I also appreciated 43 b6, which as in the puzzle position, looks like the only winning move as well.

This could make for a great endgame puzzle, because if black follows with 43...Bxc6 then after 44 Bxc6 Nd6 45 Bxd6 Kxd6, you end up with this position.

This could turn into this amazing winning position, with black to play.

  kevin86: I delayed the bishop move and made an error:

44 b7 ♘xb7 45 ♗b3 and black escapes by ♘d6.

Nov-28-12  James D Flynn: Black is a pawn up but Whites pawns are advanced and his b pawn could Q in 2 move if either his B or N could be diverted from covering the b7 square 44.Bb3 Ke7(if Bxb3 45.b7 and Queens) 45.Bxd5 g5(if Kd8 46.Bxd6 and the b pawn queens) 46.c7 Nc8 (ifKd7 47.Bxd6 and either pawn queens) b7 and the b pawn queens.
Nov-28-12  francis2012: kekekekeke I solved it! ♗b3!! a shocking sac that leads to promoting one of the pawns of White into ♕.
Nov-28-12  ajax333221: I am running some heavy things on my PC and at the moment I can't analyze with chess engines, but 44.b7 don't look bad at all:

a) 44...Bxc6 45.b8=Q Bxa4 46.Qb6

b) 44... Nxb7 45.c7

  Jambow: Ok deflect the Bishop pretty quick to see but my haste has caught me out lately too.
Nov-28-12  dumbgai: Yeah, 44. b7 Nxb7 45. c7 (instead of cxb7??) wins as well.
Nov-28-12  C4gambit: 44.b7 Nxb7 45.c7 should win
Nov-28-12  stst: objective is to rush to promote a pawn:
44.Bb3 BxB
45.b7 Nxb7
46.cxN Bd5
47.b8=Q
The rest should be piece of cake.
Nov-28-12  stst: Despite the other comments, the game proceeds exactly as I proposed: NOT b3 to start, but to divert the B first, hence 44.Bb3 ....
Nov-29-12  stst: <I am running some heavy things on my PC and at the moment I can't analyze with chess engines, but 44.b7 don't look bad at all:>

Chess engines may not be bad at all, but certainly is NOT GOOD for training one's brain. Brain work first, engines the last.
b7 to go first is NOT good for this one.

Nov-29-12  dumbgai: <stst> How is 44. b7 not good? Many people have pointed out the easy win with 44. b7 Nxb7 45. c7. It doesn't take a computer to see it.
