[ujahqdkr] Postgame analysis for chess anti-cheating

Identify the computer-like moves, either automatically using machine learning, or using other people overseeing the game.

After the game, or even during the game immediately after the suspect move, draw the player aside and have him or her explain the reasoning for the move.

Perhaps ask, why not this move instead, which looks attractive to humans but conceals a trap.  The player should be able to explain the trap having seen it.
