31. f4 |
Time to displace the bishop with the pawns! | |||||

|
31... Rg7 |
I thought f5 would have been better, since there's a neat little trick in the following line: 31...f5 32. exf5 Bxf5 33. Rd5! Rxg2+!? 34. Kxg2? Be4+! 35. Kg3 Bxd5 and black is still worse, but has some hope to draw the endgame. However instead of 34. Kxg2?, Kf3! keeps white's strong advantage. | |||||

32. f5 |
Driving back the bishop. | |||||

32... Bg8 |
Only move, so as not to interfere with the rook. Notice white's control of all the squares on the a2-e6 diagonal. | |||||

33. Bc6 |
White voluntarily gives up control of c4, because what can black's bishop do there? All black's pieces are tied down to the knight, and the king can't move out of the pin without dropping the knight, so white is free do to do what he wants. Black is not quite in zugzwang, but can't make any moves that improve his position. | |||||

33... Re7 34. b5 |
Simple - promote the pawn and win. | |||||
| | ||||||
|
34... Bf7 35. b6 |
With Rc7 and b7 to follow... | |||||
| | ||||||
|
35... Kf8 |
35...Bh5 wouldn't help any after Rd2 - again the bishop has no useful squares. But now there aren't enough defenders of the pinned knight. | |||||

36. Rdxd7 |
And black resigns, as soon the b-pawn will promote. Thanks to my opponent who defended well, and made me search for the right continuations. A crazy game, showing the importance of active pieces and also pins. Hope you enjoyed. Please comment and rate, and let me know what you liked and didn't like. | |||||
