Were there any chance to win this game and how? Thank you.

I'm guessing the time controls were pressing, particularly on move 37. An idea a bit earlier may have been to keep the c pawn by preparing its advance a bit better, instead of exchanging this pawn a pair of rooks and the a pawn. at that stage with the bishop advantage it should have been easier to pin black down and force concessions than you found on the fateful 37th. Good game overall.

You threw away your c pawn and you threw away your dark-squared bishop. Any number of moves could have prevented either or both. You need to work on your understanding of piece-trading situations. On move 31 you initiated a trade that resulted in a loss of material (a rook and a far-advanced pawn for a single rook). Sometimes we are forced into trades where we lose material, but there is rarely a reason to initiate such a trade (unless you have calculated that the sacrificed material will give you some sort of advantage). You do the same thing to even worse results on move 37, when you give away your bishop (bishop and a rook for a single rook).

I recommend you play through this game with any good chess analysis program and see what its suggestions are starting at move 25 or so. I use Shredder for the iPhone.

I believe that endgame could be won for White. Either 37 g4 or 37 h4 look promising, but I think the most clearcut is the latter (fortunately, you have the right-color rook pawn).

37 h4 gh 38 gh his problem is that any move to attack the h-pawn will allow you to play Bxf6 protecting it. 37... f4 meets with 38 hg Kxg5 39 gf+; and his only tempo move (37... Rf8) should lose to 38 hg Kxg5 39 Bd2+ followed by Bf4 (then you walk your king in there, and he can only wait for the end to come, having no play at all).

That leaves us 37... g4+ 38 Kf4. Now, normally 38... Re7 would be a hideous threat (mate in 1!), but his position is so tied up that he falls apart before your king ever gets into real danger. So what can he do there? Not much else besides the temporizing 38... Rf8; after which you can whittle down to a won pawn ending via 39 Rxf6+ Rxf6 40 Bxf6+ Kxf6 41 h5 (41... Ke6 42 Kg5).

Thank You for analyzing.
