The player with the red pieces plays with the player with the yellow pieces, and the player with the green pieces plays with the player with the black pieces. Opening setup Players have each one king, one elephant or rook, one knight, one boat, and four pawns. The opening setup is displayed below. Pawn g1, g2, g3, g4. The king , rook , and knight move as in usual chess.
Pawns move as in usual chess, but have no initial double move, and more complicated promotion rules.
Pawns move in the expected direction, i.e., every pawn must move 6 times to get to their final rank. There is no castling. The boat jumps two squares diagonally. All pieces take as they move, with one addition special case, called the triumph of the boat . When a boat moves to form a square of four boats, then he takes the other three.
