I like the new Lichess puzzles. I am always hoping to see one of my games turned into a puzzle.
Well, I never had one from my games pop up randomly, but I saw that there is one. There is a section in the puzzle meny called "Puzzles from my games" where they are listed if they exist.
No puzzles are there from my games
Oh wow. I have four puzzles, two originating from embarrassing mouseslips (unsurprisingly). I remember all of those games.
There are 93 puzzles from my games. I never encountered them accidentily n the normal training program, though.
You find them on lichess.org/training/of-player
