Could I have won this game?

This is a team match game where I made an early blunder, and struggled back to a fairly equal position. I had an extra pawn in the endgame, for his extra bishop, and I felt there should have been some way to convert it. I am talking specifically from about move 45 onwards. Thoughts? 

Any analysis would be greatly appreciated.

this is a hopeless draw...unless white plays horribly.

I am aware of that. I meant before then. If I had thought I could win at that stage I wouldn't have agreed a draw.

Well for a start 35...e4 equalized

What after 36. Bxe4?

After Rc2, his bishop is hanging...

No, I don't see a win. Ignoring the mistakes White had made earlier on, recapturing the pawn with the h pawn would have made White's life easier on move 42. Retaining the rooks may have given White better practical chances of a win, and on move 45, his best chance for a win would have been h4 (hoping that you would make some horrible mistake and allow him to trade the h pawn for your g pawn, which would have given him good chances (obviously if he trades off the other pawn it would be a dead draw due to the wrong colored bishop).

anyone smart would offer a draw

i would have killed the pawn

Be like what, exactly? I am perfectly aware that losing a piece is a loss with good play. I asked if there was a way to win, and I was told there wasn't. I don't think I know it all, and you are rather hasty in jumping to conclusions like that with zero evidence to support them. I asked for help, you gave it, I wasn't sure about your statement, so I pointed out that what you said was wrong. If I don't understand why a move is better, I will ask, that is how one learns, after all. If you are feeling insulted, you have abnormally thin skin.

There was only one post which addressed my question, by Electric Eel, which I was grateful for. You have done nothing but insult me without reason. I never expected praise, I wanted to know if there was something I could have done, except hanging the piece obviously, to improve my chances. Telling me which moves are bad is of very little use to me unless you can help me by pointing out better alternatives.

I am not good enough to see why 32.Rc2 is better for white, hence I didn't notice you meant it as opposed to 31.Rc2. 

29....dxe4?

just push d5 and you do have 2 connected passed pawns.  WHether or not they win does not matter it is the only practical chance of winning

Thank you, you are probably right. Looking at that now I have no idea why I didn't play it in the game. 

One needs pretty special position that three pawns win against bishop and two pawns. The correct question should be: can white win from move 45 onwards. I believe he could have won after 50... e3? by playing 51. f3!. After that white's king can penetrate using zugzwang. Here's how:

Well, for starters I didn't really like 14 ..., 0-0.  14 ..., Ke7 would have left your king closer to the center, and with the pawn phalanx it really wouldn't have been dangerously exposed.  And second, I think your best winning chance was after 29. Bc6 when you could have replied 29 ..., e4 giving yourself two connected passed pawns.  I'm not sure if it would have been enough to win, but the connected pawns are a lot more dangerous than the isolated passed pawn you wound up with.  And again, it would have helped if your king was closer to the center.

There's no way to win. The Bishop won't ever have to leave the h5-d8 diagonal, so once the pawn moves up, the game's drawn.

Thank you to everyone for their analysis.

tonydal, I have no doubt you are correct, but I always like to aim high :)

sedan, thank you for pointing that out, I think I have it hardwired into me that I should castle, though perhaps it is not always right.

Shakaali, I'm glad he didn't do that. However, what other move do I have available that I should do instead of e3?  

Computer analysis (2000 strength, so not as good as tonydal) says I am slightly ahead before dxe4, but that I am slightly behind after that.

Here is the analysis.

That's a good question... I actually only seriously analyzed e3 because I had a hunch that after f3 white should win (if white only has h-pawn left it may well be impossible since the promotion square h8 is of "wrong color"). Thus the question mark. Looking at it now I don't know if a move like 50... Kc4 is really any better. Actually without any further analysis I can't see any reason why white still couldn't win by similar methods: ie. by bringing the bishop to f1-a6 diagonal to control e-pawn and then try to penetrate with king.

As pointed out by others this is bit tricky ending so I didn't want to spend too much time analysing it but my intuition tells me that white should probably win.

after 51 Kxe3 it's a book draw.
