Pseudo legal moves are all moves except those that put a king in check. Essentially, these moves are legal based on geometry and not on game check rules. After the pseudo moves are generated, they can then be filtered afterwards by applying chess rules to them.

Pseudo legal moves include the following:

  • pawns: quiets, doubles, captures, promotions, en-passant

  • knights/king: from attack / move caches

  • sliders: generate moves from ray scanning

  • castling: if squares empty + not attacked
