Most of my games aren't this close, nor do they usually get down to an interesting endgame. I was definitely outplayed by my opponent, but know I could have done better...

 

 

 

 

 

 

 

After move 25 or so, was there any chance for me to win? Should I have tried to push for a draw? How would I have done that?

Also, I don't think the opening followed any main line, but are there any major flaws on either side?

In the opening, white gives up a pawn for a lead in development and active pieces. Such a trade off must be taken advantage of quickly. The material advantage is more permanent, while the lead in development is an advantage that can easily be lost.

 

The move 13. h3 is too slow for this kind of position. White should try something like Ne4 or Rf4, though honestly, white probably doesn't have compensation for the pawn.

 

Instead of 10. Nc3, I prefer 10. Bxc6. 

one thought: i think on move 25 you could have won a pawn by doing 25bxf7.  he can't take it with his rook or you'll mate him with your rook.  it might've been a different game after that with probably a stalemate

40. Kh2.  Your king should go the other way. It's your only chance.

 

42. g4. You give your opponent a passed pawn that severely limits the flexibility of your king. 

Yeah, in chess you spend most of your time worrying about the King, but in the endgame it's a really strong peice. You needed to get your King out/cetralised when there was only bishops on the board. The endgame is like any other part-you need to get you peices working together, you'd had more of a chance using your King and Bishop as a pair, rather then distant friends.

 

I'm no expert-just my thoughts.

 

Cheers min, good post.

7 Qd5 seems to win a piece--if 7... Bxf2+ 8 Kh1.  Also, it looks like 9 Qd5 was on:  9... Ng5 10 Nxg5 Qxg5 11 Rxf7 Qxe3+ 12 Kh1.

You were lost, but could have hoped for a draw with something like this on move 37.  It's not forced by any means, but would be a worthwhile swindle attempt.

I thought of 7. Qd5, too
