40. Nd7+
If you answered 40.Nd7+ or noticed the fact that Black is currently in a zugswang, then congratulations. A very interesting variation happens if White plays a waiting move such as 40.Kg2! Black cannot avoid to lose a piece. Sample lines: 40.Kg2! Bg7 (40...g5 41.hxg5 fork)(40...Re7anywhere 41.Rxe8+)(40...Rf5 41.Nxg6+ fork)(40...Kg7 41.Rxe8 Rxe8 42.Rxe8) 41.Ng5 and there are too many threats to deal with. The move I played, 40.Nd7+, also wins. Black can't take the knight: 40...Rxd7 41.Rxe8+ Kg7 (41...Kf7 42.Ne5+ Kg7 43.Rg8+ Kh7 44.Rh8+ Kg7 45.Rag8#) 42.Rg8+ Kf7 (42...Kh7 43.Rh8+ Kg7 44.Rag8+ Kf7 45.Ne5+ Ke7 46.Rh7+! with mate to follow) 43.Ne5+ Ke7 44.Rge8+ Kd6 45.Ra6+ with mate to follow. Anyway, 40.Nd7+ at least forks the king and a rook.

40... Kg7 41. Rbxe8
Black still cannot take my knight. I could have played 41.Nxf6 first instead but I thought my knight has more value than his rook.

41... Rxe8
Black avoids the trap once again, but he is still lost.

 
42. Rxe8 Rf7 43. Nfe5 Rxd7
43...Rf5 44.Rxe6 isn't much better.

 
44. Nxd7
The rest is just technique.

I finally snatch the a pawn.

 
49... Bh6 50. Ne5 Bf8 51. Ra8 Kg7 52. Rxf8
I trade Black last remaining piece to simplify the endgame.

Black resigns, as he can't stop the promotion. Feel free to comment and rate!
