Setup: Normal except also have an extra, empty board (called the zombie board).
Gameplay: When a piece is taken off of the normal board, it is placed on the zombie board on the corresponding spot where it started. If there is a piece on its spot then that piece leaves the board.
Once the normal board has a checkmate, move the kings to the zombie board and leave all remaining pieces untouched on the normal board.
To win: The normal board must be in a state of checkmate and then the player who achieves checkmate on the 2nd board wins. The player who was in checkmate on the first board doesn’t affect who wins.
The winner on the normal board gets to move 1 extra piece to the zombie board.
The winner on the normal board gets to choose where the king is placed on the zombie board.Pieces moved to the zombie board can be place wherever desired
