| Dec-14-14 | | drunknite: more B endgames. I think Nimzo makes the right calculation on move 65, then he gets carried away with move 66. I think if he just 66 Kf4 and takes the pawn next move it is fine, the K is in good position, for the B action (not sure how well theory was at this pt. the famous Yates/Capablanca game was years later). Finally on move 72 he takes a wrong turn there, isnt it 72 Ba5, then then 73 Bc3+ to save it? am going pretty quick here so maybe double check. |

By move 72 it's a tablebase win for Black. 72. Ba5 b3 73. Bc3+ Kd5, followed by ...Kc4 etc. |

<66. Kf4 and takes the pawn next move>
66. Kf4 Bxb4 attacks the bishop. After it moves, 67...Kd3. |

| Jan-08-16 | | JohnBoy: <whiteshark> - Your sample line is pretty clearly not in blacks best interest. Better is 15...gf5 so that white must, at the very least, have a response to the threatened ...f4. |

| Aug-27-19 | | zydeco: 57.c5 is insane. 57.Be3 should draw pretty easily. |

<57. Be3 should draw pretty easily>
It might be a draw, but at least it doesn't look easy to me. And yes, I tried making the move on the display and hitting the engine button, but remain unconvinced of the easiness. |

| Aug-28-19 | | zydeco: <beatgiant> White can just shuffle the bishop between e3 and d2. Then when black plays ....Bg5 white takes the pawn on c5, black takes on e4, white takes on g3, then trades off the b pawn for the c pawn and sacrifices the bishop for the e-pawn. A sample is:
57.Be3 Bd8 58.Bd2 Be7 59.Be3 Bg5 60.Bc5 Kf4 61.Bxb4 Kxe4 62.Bd6 Kd4 63.b4 followed by 64.Kxg3. A key point is that after 60....Bd2 61.Bf8! black's king can't cross to f4 because of 62.Bh6+ winning the bishop. |

Yes, but I think your line is pretty tricky to calculate over the board. In the following position after Black's move 61 in your line: 
click for larger viewWhite has to find your <62. Bd6!> because the obvious 62. Kxg3? Kd3 looks close to winning for Black. But with 62. Bd6 Bf4 63. b4, White's queenside play comes just in time to save the game. And I will admit that I did not see that at first look. So either it is easy and I'm a weakie, or it's not easy and you're a lot stronger than me - take your pick. |

| Sep-05-19 | | zydeco: <beatgiant> Agreed. It's not actually so simple. But it's almost always a horrible mistake to put pawns on the same color square as the bishop in these endgames. |

<15.exf5!> would have given White a clear advantage, e.g. <15...Bxf5 16.Nxf5 gxf5 17.gxh6 Bxh6 18.Rg1 > JohnBoy: <whiteshark> - Your sample line is pretty clearly not in blacks best interest. Better is 15...gf5 so that white must, at the very least, have a response to the threatened ...f4.> JohnBoy's comment looked quite right to me, but after 15.ef gf 16.Nh4! f4 17.Ne4 fe 18.fe SF10 has a +6 evaluation. White just rolls his heavy pieces over and Black is too snarled up to do anything about it. Incidentally, after 15.gxf6 the evaluation swings to about -1. That's a huge shift for a move that doesn't blunder a piece. |
