Chakra (chess variant) in "100 Other Games to Play on a Chessboard" (1983, 2002) by Stephen Addison. Chakra is played on a standard chessboard and has many of the standard play conventions as in chess, including check and the winning objective, checkmate. Stalemate, as in chess, is a draw. The king in Chakra is named "emperor". Each player starts with 16 pieces: 1 emperor, 1 empress, 1 samurai, 1 monk, 2 monkeys, 2 courtesans, 2 chakras, 6 swords. The emperor, empress, and monkey perform identically to their chess counterparts (king, queen, and knight, respectively). The others are governed by special fairy rules. There
Hridayeshwar Singh Bhati can play. Bhati's multiplayer design employs all the standard chess pieces and their moves. Individual armies are distinguished by colour. Each player starts the game with the same number and types of pieces as in standard chess. Non-pawn pieces start in their normal positions on the (the 8×1 extensions at the board perimeter), with queens always placed to the left of kings. Pawns are placed on the rank in front of the pieces as in standard chess. Red squares cannot be occupied or passed through when moving or capturing. The multicoloured central area can be passed through but not occupied.
