Three player chess is a family of chess variants specially designed to be played by three people. There are many variations of three-handed chess. They usually use some non-standard board, for example, hexagonal or three-sided board connected in the middle in a special way.
Three-player chess (and other games) variants are the hardest to design fairly, because the imbalance created when two gang up on one is usually too great for the player to withstand. Some versions avoid this problem by deciding victory such that the third player loses as well as the checkmated player, leaving the player who delivers checkmate first to be the victor.
