Find a win for black?

I wouldn't call the King's Gambit all that unusual...

The fourth move by Black is a poor move.

Are you sure your opponent was 2000+? You must have been playing very short time controls.

I'm not going to comment on the messy middlegame, but there is a definite win after her twenty-fourth move - check the move list after this move; see below:

 You had an advantage in pawns.

Lucky for me my opponent was suffering some illness... allergies clouding her mind I bet!

Thanks for your input!

Kf1 looks really bad, but in reality it is ok. 4. .. Bc5 isn't good because of the reply d4, i like 4. ..Nf6 better.

on 12. dxe5 white misses a forces win. White should play

12. Rxa5 Pc6

13. Rc5 and wins.

i Don't like 15 .. Bxf3 because with the trade you are actually helping white. A better idea is Nc6 developping the pieces and then maybe Re8. You loose the pawn on c7, but you shouldn't care too much. Your pieces are active and the white king is still in the middle...

32. .. f4 is a blunder, Ne4 should be played.

About the end game, this is a typical example where the bishop pair is really strong, the extra pawn for black doesn't matter.

At least my 2 cents...
