Rules of Avalanche Chess
All rules from normal chess apply, except that every turn has two parts. First a normal legal chess move, then one of the opponent's pawn is pushed one space forward (towards yourself).
A few extra rules are needed to clarify how certain situations are handled:
- The first part of the move must be a legal move. You may not place your king in check and then use the pawn push to get out of check.
- The second part of the move (the pawn push) is omitted if there are no pawns which can be pushed.
- If a pawn is pushed such that it places the player's own king in check, he loses the game immediately, since his king would be captured on the next turn. This applies even if he mates his opponent on the same turn, since his king would be captured first.
- If a pawn is pushed onto the last rank, the owner of the pawn decides what piece to promote it to. If the promotion results in check, the game is over according to the previous rule, since the king would be captured.
- There is no en-passant capture.
