So I've played this game recently and I find it very interesting. The game was not perfect whatsoever, but there is a lot to learn from this game.

I played black and white resigned after reaching the end game and he did not feel like playing with a pawn down.

 I hope this game will be helpful as it was for me.

I'm rated much lower than you but after Ra1 isn't Black's extra pawn useless?

E.g.: 29. Ra1 Ra8 (and the black rook is tied to the defence of the pawn) 30. Kf3 Kg7 (and then white just fights till the end since the rooks are turned off)

I dunno lol I'm only rated 1200 you'd know better than me. =p

Best play according to computer analysis (rybka engine): 29. Ra1 Ra8 30. Ra5 Kg6 31. h4 Rh8 32. Rxa5 Rxh4 and black should be able to keep the advantage.

 The situation when white resigned is absolutely playable, but white chose differently.
