    Title has a typo: generic -> genetic

    I'm a terrible chess player, which I don't mind. But a side effect of this is that I cannot find decent chess problems. Forget a mate three, I'm at the level where I miss obvious forks. Problem is, there doesn't seem to be a decent size collection of such problems. You'd expect there to be quite some demand for it. Maybe I should try to create a few with this system.

    For easy of copy-pasting, the FEN for the puzzle with the abundance of knights is

      N1n1NN2/qNN5/5NK1/1n1nNnNN/n1Pn4/kn2n1NN/nRR1nn2/3nn1Nn w - - 0 1
    I guessed the first move right, but calculating the continuation was too messy for me.

    I'm curious why he sets Stockfish depth to 10 when he's looking for mate-in-3 puzzles. Surely 3 is all he needs?

    See also generation of a chess variant's puzzles, which is much more thorough & gets much better results by throwing the kitchen sink at it: https://samiramly.com/chess

    Can someone skilled in the art tell me where can I learn more about generating those puzzles? Are puzzles on chess.com hand-crafted, or are they generated with an algorithm?
