 |8×4 version of Alice chess
}}

Black starts out on board '''B'''; transfers are optional; non-pawn pieces may make ''zero'' moves (and may capture in so doing); a king is checked when an opposing piece sits on the king's zero square; mate must cover the king's ability to flee via a zero move. By Jed Stone (1981).

Parton also introduced a smaller, 8×4 version of Alice chess (see diagram). He also observed that Alice chess can be played using ''three'' boards instead of two. (Players then having a choice between two boards when transferring pieces.)

Alice chess rules can be adopted by practically any other chess variant too, by simply doubling the number of gameboards in the variant and applying the piece transfer policy (for example, [[Raumschach]] using two 5×5×5 boards).
