27. Qa6
|
The f1 square had to be defended, or black threatened 27. ... R5f1 28. R(any)xf1 Rxf1 29. Rxf1 g2 , winning. |

|
|
|
27... Rg8
|
Now g2 needs to be defended, or 28. ... g2 29. Rxg2 Qxg2# is checkmate. |

|
|
|
28. Qe2
|
White's best defensive move (the other option was Rg2). |

|
|
|
28... Re8
|
Another nasty pin. But possibly the winning move was Re5, since after 29. Qf3 (the only way to defend g2 and e3 while stepping out of the pin), Rxe3 wins. |

|
|
|
29. Qd3
|
This is a good move, since there's no more mate threat on g2, and this is an effective pin of the Rf5 to the queen and king. |

|
|
|
29... Qh5
|
Threatens mate on h2, but this is easily defended by Rg2. Black may win a pawn again, but the pin on the Rf5 is more important than he thinks. |

|
|
|
30. Rg2 Rd8
|
? After all of black's play, this move costs him everything. Black thinks he's going to get a great discovered attack on the queen after Bc7 or Be7, but in reality, he's just stepped INTO a brutal pin. And this is because... |

|
|
|
31. Bxc5
|
! The rook on f5 is stuck, and a recapture with the bishop would leave the rook on d8 hanging! At this point, I thought Bc7 offered black the most chances, but he chose to go to an inferior endgame with... |

|
|
|
31... Qf3
|
? Perhaps overlooking that after exchanges of the queens... |

|
|
|
32. Qxf3 Rxf3 33. Bxd6
|
...white can exchange off the two minors... |

|
|
|
33... Rxd6 34. Rxg3
|
And win another pawn, giving him a decisive endgame advantage. |

|
|
|
34... Rf2
|
Black fights on for 25 more moves, and white almost blows it AGAIN, but right now white has a huge edge, and, in fact, threatens mate with his next move... |

|
|
|
35. Rag1
|
But this is easily parried and is unproductive for white. |

|
|
|
35... h5 36. Rg3g2
|
Getting the rook off of the second rank... |

|
|
|
36... Rxg2 37. Rxg2 Rd1+ 38. Rg1 Rd2
|
Where it's replaced by his brother. At this point, I should have remembered my endgame principles, put the rook behind the c-pawn, and just marched to victory. Instead, I made it... er... exciting. |

|
|
|
39. Rb1
|
? Why would I want to hold on to a second pawn? If I played Rc1 here and just started pushing, black could've played Rxb1, Rxa1, Rb1, and pushed the a-pawn all he wanted -- I would've gotten there first. |

|
|
|
39... h4
|
Still not too late for me to play Rc1... |

|
|
|
40. a4
|
Geez, it's like I'm trying not to win. |

|
|
|
40... Rc2
|
Well, black knows what to do. The best place to put a rook is behind a passed pawn, no? |

|
|
|
41. Re1
|
"threatening" Re7 , forking king and pawn. Do I even realize that if black plays h3 and I move the rook, Rc1 is checkmate? |
