Avalanche chess

Avalanche chess is a chess variant designed by Ralph Betza in 1977. After moving one of your own pieces, you must move one of your opponent's pawns forward one space.

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.
