Normal chess where both sides may cheat, at the risk of getting caught.
How to play
Normal chess, but you may cheat: besides legal moves (dots), you can move any piece to any square within 2 steps that isn't yours (red dashed rings) — you just can't capture the king, give check, or leave your own king in check. Each cheat has a 40% chance to be caught: the move is undone and you lose a random piece. The bot cheats too; the referee catches it 30% of the time, and you can press Accuse! right after its move — right and it loses a piece, wrong and you lose one. Checkmate wins.
