Chess for 3 has sought to incorpore the same spirit as classical chess (for two players); hence, strategy, logic reflexion remain the essential elements of the game. Unlike games of chance, classical chess was conceived so that two players could oppose their reflective capacities in a competitive way on a board of 64 squares.

To introduce a third player demands an expansion of the traditional board (i.e. 64+32=96 squares) and requires also a change in the rules. The rules of the new game must insure that each player has an equal chance of winning. In order to maintain the interest of serious chess players, the new rules must also avoid the possibility of two players joining forces against one.
Indeed, the principle of  "Chess for three" is to give one player the possibility of using his numerical disadvantage (in terms of points) as a strategic force.

Being inspired by the notion of sacrifice in classical chess, this elementary principle gives the weakened player new power.

A weakening in terms of points (3 are diplomacy or sympathy of one player for another, are of no use on the "Chess for three" set. Chances are equal for each player; strategy can only be used on an individual basis. The rule of non-aggression at "Chess for three" repositions the players and so a balance is found, because it is not two against one but one against two.

Rules of "Chess for three"
The chess-men are placed on the "Chess for three" board in the same way as in traditional chess, except that each of the three kings are placed on the black square on the right of the queens. The three players are placing in an attacking position. White, Brown and Black are the colors of the chess-men and their respective territories. The turn is played counter clock-wise. Order of play is White, then Brown, then Black.
The game ends at the first checkmate or the first stalemate. Therefore there are always three players in a game of "Chess for three" .
The player who holds simultaneously the other two in check wins. This double check has the value of a checkmate.
There is a check-and-stalemate in 2 cases: when you checkmate simultaneously the two other players and when you checkmate one player and check the other one in the same time.
There is a stalemate when the pieces of 2 players are necessary to checkmate the third one. There is a checkmate only when one player pieces are sufficient to obtain the checkmate. No piece of the third player has to be necessary to obtain it.

Rules on non-aggression in "Chess for three"
Rules of non-aggression is based on the value of the chess-men and the principle is that you are not allowed to take any chess-man on the territory of the player who stands 3 points late except if the attack is directed against the king.
More precisely, a player who has lost 3 points or more will not be able, on his territory, to have one of his chess-men be taken by a player who is 3 or more points ahead of him except if the attack puts him in a check position.


White has lost 2 points, Brown 4 points and Black 5 points.

There is 1 point difference between Red and Black: Brown and Black can capture each other, freely, with no restriction.

There are 2 points difference between White and Brown: White and Brown can also capture freely with no restriction.

There are 3 points difference between White and Black: Black must obey the rule of non-aggression versus White; Black can capture White, but White cannot take any Black chess-man on Black territory, except if the attack puts the Black king in a check position.

Value of chess-men
  • The¨Pawn is worth 1 point i.e., 8 pawns= 8 points
  • The Bishop is worth 3 points i.e. 2 Bishops= 6 points
  • The Knight is worth 5 points i.e. 2 Knights= 6 points
  • The Rook is worth 5 points i.e. 2 Rooks= 10 points
  • The Queen is worth 9 points i.e. 1 Queen= 9 points

Total = 39 points

How the pieces move

  • The King
The king is the most important piece, but is one of the weakest. The king can only move one square in any direction - up, down, to the sides, and diagonally. The king may never move himself into check (where he could be captured).
  • The Queen
The queen is the most powerful piece. If moved she can move in any one straight direction - forward, backward, sideways, or diagonally - as far as possible as long as she does not move through any of her own pieces. And, like with all pieces, if the queen captures an opponent's piece her move is over.
  • The Rook 
The rook may move as far as it wants, but only forward, backward, and to the sides. The rooks are particularly powerful pieces when they are protecting each other and working together!
  • The Bishop
The bishop may move as far as it wants, but only diagonally. Each bishop starts on one color (light or dark) and must always stay on that color. Bishops work well together because they cover up each other’s weaknesses.
  • The Knight
Knights move in a very different way from the other pieces – going two squares in one direction, and then one more move at a 90 degree angle, just like the shape of an “L”. Knights are also the only pieces that can move over other pieces.
  • The Pawn
Pawns are unusual because they move and capture in different ways: they move forward, but capture diagonally. Pawns can only move forward one square at a time, except for their very first move when they can move forward two squares. Pawns can only capture one square diagonally in front of them. They can never move or capture backwards. If there is another piece directly in front of a pawn he cannot move past or capture that piece.

Particular Rules

Pawns have another special ability and that is that if a pawn reaches the other side of the board it can become any other chess piece (called promotion). A pawn may be promoted to any piece (except pawn of course :) ). [NOTE: A common misconception is that pawns may only be exchanged for a piece that has been captured. That is NOT true.] A pawn is usually promoted to a queen. Only pawns may be promoted.

En Passant
The last rule about pawns is called “en passant,” which is French basically means “in passing”. If a pawn moves out two squares on its first move, and by doing so lands to the side of an opponent’s pawn (effectively jumping past the other pawn’s ability to capture it), that other pawn has the option of capturing the first pawn as it passes by. This special move must be done immediately after the first pawn has moved past, otherwise the option to capture it is no longer available.

One other special rule is called castling. This move allows you to do two important things all in one move: get your king to safety (hopefully), and get your rook out of the corner and into the game. On a player’s turn he may move his king two squares over to one side and then move the rook from that side’s corner to right next to the king on the opposite side. In order to castle, however, it must meet the following conditions:
  • it must be that king’s very first move
  • it must be that rook’s very first move
  • there cannot be any pieces between the king and rook to move
  • the king may not be in check or pass through check
Notice that when you castle one direction the king is closer to the side of the board. Here is also a little bit different from classic chess, people who are familiar will notice it. That is called rightside . Castling to the other side, through where the queen sat, is called castling leftside. Regardless of which side, the king always moves only two squares when castling.

Check, Checkmate and Capture
As stated before, the purpose of the game is to capture opponent’s king. This happens when the king is put into check and cannot get out of check. There are only three ways a king can get out of check: move out of the way (though he cannot castle!), block the check with another piece, or capture the piece threatening the king. If a king cannot escape checkmate then you miss your turn and wait. It is also possible the other player to save you. The chance to do it is big, because only the player who capture the king is winner. If not so, the king is captured and the game is simply declared over. The player who captured the king is the winner.

Occasionally chess games do not end with a winner, but with a draw. There are 5 reasons why a chess game may end in a draw:
  1. The position reaches a stalemate where it is one player’s turn to move, but his king is NOT in check and yet he does not have another legal move
  2. The players may simply agree to a draw and stop playing
  3. There are not enough pieces on the board to force a checkmate (example: a king and a bishop vs. 2 kings)
  4. A player declares a draw if the same exact position is repeated three times (though not necessarily three times in a row)
  5. Fifty consecutive moves have been played where neither player has moved a pawn or captured a piece.
