Triune Chess

By Sergey Sirotkin

Introduction

If you have three players, but only a single regular Chess set, you can take turns playing one pair, then another, etc. However, someone is always sitting out. Triune Chess is a scheme that allows all three players to play at the same time.

Rules

The game is played by the usual rules of orthodox chess, except for who moves which pieces. The sequence of turn and color is as follows:

Turn     Player A   Player B   Player C

 1.       White      Black      White
 2.       Black      White      Black
 3.       White      Black      White 
 ...      ...        ...        ...

Turn       White        Black

 1.       Player A     Player B
 2.       Player C     Player A
 3.       Player B     Player C
 4.       Player A     Player B
 ...      ...          ...
