Check your opponent 3 times to win the game.
- All the Laws of FIDE chess apply. In particular, a move is legal if and only if it would have been legal in FIDE chess.
- If you make a legal move that puts your opponent's King into the third check, you win.
The winning move has to be legal, e.g. you can not give the third check while in check. Checkmating your opponent is still a legal way to win.
A move is considered to give ONE check if the King is threatened, regardless if multiple pieces are giving the check (in the event of a double check).
