ALICE is one of the top 20 played chess variants in NOST and David Pritchard in his Encyclopedia of Chess Variants recommends it as one of the best variants. Personally, I think it is one of the few variants that has that 'neato' quality to it; one of the most fun to play variants.
The standard game of ALICE Chess is played using two boards, A and B. All pieces move as in standard chess. The normal array is on board A; board B starts empty.
The starting setup:
Board A Board B +---+---+---+---+---+---+---+---+ +---+---+---+---+---+---+---+---+ 8 | R | N | B | Q | K | B | N | R | | | | | | | | | | +---+---+---+---+---+---+---+---+ +---+---+---+---+---+---+---+---+ 7 | P | P | P | P | P | P | P | P | | | | | | | | | | +---+---+---+---+---+---+---+---+ +---+---+---+---+---+---+---+---+ 6 | | | | | | | | | | | | | | | | | | +---+---+---+---+---+---+---+---+ +---+---+---+---+---+---+---+---+ 5 | | | | | | | | | | | | | | | | | | +---+---+---+---+---+---+---+---+ +---+---+---+---+---+---+---+---+ 4 | | | | | | | | | | | | | | | | | | +---+---+---+---+---+---+---+---+ +---+---+---+---+---+---+---+---+ 3 | | | | | | | | | | | | | | | | | | +---+---+---+---+---+---+---+---+ +---+---+---+---+---+---+---+---+ 2 |[P]|[P]|[P]|[P]|[P]|[P]|[P]|[P]| | | | | | | | | | +---+---+---+---+---+---+---+---+ +---+---+---+---+---+---+---+---+ 1 |[R]|[N]|[B]|[Q]|[K]|[B]|[N]|[R]| | | | | | | | | | +---+---+---+---+---+---+---+---+ +---+---+---+---+---+---+---+---+ a b c d e f g h a b c d e f g hThe rules are very simple. In turn, each player makes a single move on either board following these three rules:
There are less played variations of ALICE Chess. One variation is to simply have all Black's pieces start on board B. Another, MS. ALICE Chess, allows 'zero' moves. To make a zero move, simply transfer a piece to the same square on the other board. Kings may not zero while in check.
Parton also suggested a smaller version, played on two 4x8 halves of a single board:
