Quatrochess is a chess variant for four players invented by George R. Dekle Sr. in 1986.[1][2] It is played on a square 14×14 board that excludes the four central squares. Each player controls a standard set of sixteen chess pieces, and additionally nine fairy pieces. The game can be played in partnership (two opposing teams of two) or all-versus-all.
Quatrochess was included in World Game Review No. 10 edited by Michael Keller.[3]
