| Buddy Revell: Zugzwang and, to add insult to injury, mate in a few moves. |

| GMNick: Good maneuvering by black to force the zugzwang and win a good endgame. |

| wouldpusher: 20. ...  xc1 gave Black the advantage of a Bishop pair, which he used to press his advantage until the endgame. |

| piever: I don't know what is Piza's rating, but against a 2647 rated player I would have taken the draw at move 6... |

| PinnedPiece: If not 59 NxF2, then 59...Bb8 game over. |

| Mizerak: What am I missing? Even after the h3 pawn falls, doesn't White just keep the king on h1 and the bishop on the h1-a8 diagonal? Black cannot trade white bishops, as the rook pawn is the wrong colour. I realize there may be something simple I am missing - I just want someone to point it out. :-) |

| Mizerak: Ah. Black gets the pawn to h3, and brings the bishop to g2 via f1. Never mind. :-) |

| Nimzoholz: 70. Bf1 hoping for Kxf1 stalemate is a pipedream. Black has much better with 70...Bb7+ and mate is in 1 move. |

| kevin86: An unusual ending!
In the fullness of time,black will
1 capture the pawn at h3
2 move the bishop to f1
3 move the pawn to h3
4 mate after  g2+ xg2 hxg2#
And time is approaching its fullness.
White can only hasten the process-not defer it. |

| SuperPatzer77: Why White resigns is because White is in a complete zugzwang. 70. Bc6 Bxh3, 71. Bb7 Bf1 (getting the Black h-pawn to h3), 72. Bd5 h3, 73. Ba8 Bg2+, 74. Bxg2 hxg2# 0-1. If White tries to save the White h-pawn with 70. Bf1, Black declines to capture the White Bishop at f1 because of stalemate and then forces checkmate with 70...Bb7+. |

| Magic Castle: <Mizerak:> yup. Its mate by pawn afterwards. |

| ajk68: 30. Rd2?
Trading down into an endgame against a bishop pair with pawn imbalances on both wings. It would be interesting to see if white can hold after move 30 with accurate play, but this is way beyond me. I would be interested if 47. Ba6 would work. White would go down a pawn but enter into an opposite color bishop endgame. |

| Jimfromprovidence: White should draw with 45 Bb7, limiting black's endgame mobility as displayed in the text by forcing the white bishop exchange. (Black must exchange or lose the a pawn.)
click for larger viewAfter 45... Bxb7+ 46 Nxb7 below, it does not appear that either side can make additional progress.

| Manic: <Jimfromprovidence> Doesn't white's knight vulnerable position leave black at least a small advantage after 46...Bb6, where if 47.a4 then 47...a5 and now sooner or later white will have to try and free the knight with b4, giving black a passer. |

| sleepyirv: I'm missing the logic behind 35. Ba8. Is it out zugzwang? |

It sure looks like a drawn position, doesn't it?

| Manic: <Jimfromprovidence> Yeh sorry I forgot that white could play b4 to free the knight. |
