Idea: Personal Puzzles or Filtered Puzzles

I think it would be neat if there was a feature that created puzzles from your own historical game positions. I like that the puzzles come from other real games; however, if there were a way to study all of the positions where I missed punishing my opponents blunder in my own games, then I would be able to study puzzles and improve my game based on my own play style.

Alternatively, maybe there could be puzzle filtering. I might want to study puzzles that occurred in QGD or QGA openings or French openings. That would be neat as well. Some of the puzzles are less relevent to me as a player because I don't play those lines, so I don't see those positions in my own games.

Although not exactly what you are talking about, lichess does offer "learn from your mistakes" when you are analyzing your game, and effectively gives one move puzzles that you failed during the game.

Correct. I have used the "learn from your mistakes" feature. I agree it is a good feature. It is not quite what I am looking for. I enjoy solving many puzzles in a single session. If they were puzzles from my own games or filtered to my opening book, then that would be more helpful to me.

@tailuge wow. I got discouraged for like 3 seconds when I saw so many of my blunders on the screen at the same time. It feels like a list of my sins. This is a really helpful tool. Thank you!
