In Left-Right Chess there are 7 piece types. Pawns, Bishops, Rooks and Kings are used, as in chess, and there are 3 other piece types:

Moves of unicorn:

Moves of left:

Moves of right:

Moves of flag:


Pawns can promote to any piece type in the setup, except for a king. They can initially advance 2 or 3 steps, rather than just 1 step, if unobstructed. Capturing en passant, is allowed, even if the pawn took a triple step. The capturing pawn would land on the square that is diagonally in front of it on the same file as the enemy pawn that just moved. Here's a link to Omega Chess, which has very similar rules governing legal pawn moves; note the examples of en passant captures: Omega Chess

There is no castling in Left-Right Chess.

Stalemate is a draw, as in chess.
