This is another one of my games in which i have won due to the advantage of one or two pawns

Well mijfil, you played well, but 2..f6 was a blunder. This is one of the oldest tricks in the books. You play Nxp pxp Qa5+ and go from there. Black is certainly doomed after 2..fg

Just for future reference.

Fil! You missed the Damiano's defence trap, after all the times I told you to look out for it! I might as well disown you right now , but nice work anyway

That game should have been drawn if black simply captured the last pawn with his bishop

Agreed.   I was going to say that you didn't win with the advantage of one pawn, but by bad endgame defenses.
