Hey guys, here's a link to my game I'd like you to take a look at:

As you can see, it remains pretty equal until the later parts. The thing is, I'm nearly positive there wasn't a single move/blunder that lost it for me (the 2500 rated computer analysis confirms this). Where, in your opinion, did I go wrong?

From move 31, where I went down a pawn due to white's fork, was a draw possible?

Thanks 

After 28. Nxc8+, the computer gives +.99. 

But taking the bishop guaranteed he'd be up a pawn after 28...Rxc8 29. Rb7+ and the pawn fork, so I can't blame him for doing that. 

First off 13. f4 was a mistake.  It allows the imprisoned bishop on g7 to see the light.  13...exf4 14. Bxf4 Ne5 is a dream come true  for black.  White played a pawn break for him.  I can't fathom why a 2500 computer would miss it.  Looks pretty obvious.  Bh6 wasn't the losing move, but it sure missed a chance.

Also, I don't think a draw was possible after move 31, two passed pawns and an active rook.  

After blacks 35 a4, have a look at Bb5 ch, i think you are winning. If the king moves to d8 you take the f pawn, black takes the c pawn and you take the h pawn threatening rh8 ch to win his rook . havent sight of board now but look hard at bb5ch.

If his king moves to the K side you push the d pawn fast!

I reckon a draw was very much possible if you kept that annoying knight out of b6. That was a real thorn in your side in the ending here. Just 24...Bd7 would have held down the fort I suspect. It's always sad to give up a bishop in the ending but there was very good reason here.

Before that it looks like White is going to lose something after 13...exf4 because your bishop is now hitting the c3 knight. You should be happy just to open that diagonal just on general principles but you would have won some material too.

On move 16 your choice was fine, but again exf4 looked better. You would get a pretty superb post for the knight on e5 in that case and possibly the g pawn could advance and those connected pawns could deliver some grief.

Thanks Pad, that helped
