FOUR PLAYER CHESS

The board and opening setup The board consists of an 8 by 8 board, with at all four sides an extension of size 8 by 3 added. The board is checkered, with a black square in the left-most corner(s). Each of the four players has a normal set of pieces, in four different colors, clockwise: black, yellow, red, white (drawn in different colors in the picture below). Note that the queen is always on the left side of the king in the opening setup.

Rules of the Game Each player sets up normally in his 2x8 sections.

Rules of the Game Squares such as C2,B3 are NOT considered diagonally adjacent.

Rules of the Game Pawns move away from their starting sides and promote when they reach the opposite end. (e.g. white promotes on row 12 and A10, B10, K10, L10).

You must move out of check if possible (even if other player is in check). Move king, or eliminate "threat", or block.

If you can not move out of check, then you must PASS.

If you may not move, you must PASS.

If a player A takes player B's king. B loses If a player A takes player B's king. B loses. The 2x8 section of board belonging to B is removed. All pieces on it are removed. (if there are kings on it, other than A's, then they lose as well, and remove their 2x8 sections, and so on ...). Player A can replace any missing pieces in a starting square of his for such a piece. B's remaining pieces remain on the board as inert obstacles. They do not move, nor do they threaten check, but they may be captured.

En passant captures are possible by any of the 3 following players after a player advances a pawn 2 spaces. So after pC2-C4, pB3-D3, nB5-C3 ... the move ... pD4xC3 takes both pawns and the knight!

Play is clockwise. Last remaining player wins.

When a pawn reaches the last rank of his partners row (or one of the other four fields where the edge of the board obstructs its move), then it reverses direction, and moves further in the opposite direction. When it again would reach the last rank, it again reverses direction, etc. When a pawn's move is obstructed by a pawn of its partner, it can leap over it, provided the square it moves to is vacant. This is possible, even when both pawns move in the same direction. (Mark pawns going in the opposite direction to keep track which direction they are going.) When a player is checkmated, he may not move, and he must pass his turns. His pieces remain on the board, and may not be captured. These pieces do not give check.

A mated player can be released from mate, either by his opponents, or (more commonly) by his partner. When a player releases an opponent from mate, he may not do this by capturing one of the pieces of the mated player. The team that checkmates both opponents wins the game. All other outcomes (except of course when a team resigns) are a draw.
