Four-player chess (also known as Four-handed, Four-man, or Four-way chess) is a family of chess variants typically played with four people. A special board made of standard 8×8 squares with an additional 3 rows of 8 cells extending from each side is common. Four sets of differently colored pieces are needed to play these variants. Four-player chess follows the same basic rules as regular chess. There are many different rule variations; most variants, however, share the same board and similar piece setup.
The Cox-Forbes theory of the origin of chess asserts that a four-player version was the earliest form of the game. A description of a four-player chess game is found in an Indian text written c. 1500. The Tithitattva of Raghunandana describes such a version, which continued to be played into the 20th century.
The first documented example of a modern four-player chess system was written by Captain George Hope Verney in England in 1881.
The most common form of play is two vs. two in which allied pieces cannot eliminate each other, but help the others in defense and offense. The allied players sit across from each other and help checkmate the people to the left and right of them. The game is over when both opposing kings are checkmated. If only one can be checkmated, the game is a draw.
Singles is substantially harder than team play. In this method, each player can attack any of the other three players and vice versa. Once a player is checkmated, the checkmated player can either remove their pieces from the board, or the player that checkmated can use the remaining pieces during that player's turn. Play continues until only one player remains.
Common game rules
- Players can only move their chess pieces on their turn.
- If a player is placed in check, that player must wait until their designated turn before that player can respond to the threat. However, in most variations, in the event a player's move places an opponent in check at the hands of another opponent (for example, by moving his knight so as to expose one opponent's king to another's rook), the second opponent is forbidden from capturing the first's king until he has a chance to deal with the check. Some variations prohibit moves that would cause one opponent to be in check at the hands of another. These restrictions are intended to discourage collusion between players, as further discussed below.
- Pawns move forward only, unless attacking in a diagonal forward manner.
- In the event a pawn reaches the King's row to the left, right or directly across, that pawn shall receive all the privileges of a pawn reaching King's row during a traditional chess game (i.e. promoting to a queen (most commonly), a rook, a bishop, or a knight).
- It is illegal for two or more of the players to team up (by combining their pieces) against one, unless stated before the game starts or unless the game is team based. Because collusion can be difficult to detect and/or prove, most variations place restrictions like those discussed above that are designed to inhibit players from coordinating their moves to checkmate other opponents.
