I haven't heard of any such programs, because it would take a sophisticated algorithm to correctly distinguish which positions are similar or not - even slight changes in piece placement or pawn structure can change a whole position.
What I try to do is, after each game, try not to make the same mistakes I made again, and really analyze it carefully to drill it into my head.
OK, but I'm sure a program could find identical positions in which the same mistake was made, if not positions that are structurally very similar. The idea is that there are some positions in which I routinely make the same blunder, and fixing those are a higher priority than analyzing a unique mistake I made only once in an individual game.
Well for starters it helps if you do not resign games after 5 moves to deflate your rating. That gets you banned.
So I've played over 10000 games on chess.com and now have a rich database of games that tells the story of my chess playing abilities- the openings I've tended to play, the style I've used in the middlegame, and the endgames I've mastered. Rather than analyze each game individually, however, I would like to run a computer analysis of the entire pgn archive that will recognize positions where I have made the same mistake in the same position in multiple games (such as falling for the Elephant Trap multiple times). I'd also like to know the frequency at which I play certain openings, for example, what percent of my games are Queen's Pawn Opening vs King's Pawn Opening vs English Opening. Are there any free computer programs available that I can easily use or download that can do this for me?
