Rules are as normal chess except for the following. After you move one of your own pieces, you must move one of your opponent's pawns one space forward toward you. If none of the opponent's pawns can be moved, then that part of the turn is skipped.
- You cannot use your opponent's pawn to capture.
- You cannot move your opponent's pawn two spaces forward.
- If you move your opponent's pawn to promotion, then your opponent chooses to what piece it promotes.
- If moving an opponent's pawn gives check to you, then your opponent wins the game immediately, even if you mated your opponent previously that same turn.
- A player in check is not required to get out of check until the end of that player's turn.
