The Chess Variant Pages

Too Many Bishops

Dr Cliff Pickover wrote a large number of books. In his book Mazes for the Mind he describes, amongst many other things, a number of chess variants. One of them is the game described below. Pickover's website can be found at


In addition to the usual rules of chess, each player receives every turn an additional bishop, put on the board on a square of his opponents' choice. I.e., before a player makes a normal move, his opponent places a bishop on an empty square to his choice.

Check is ignored, and the game ends when a player captures a king. The game also ends (in a draw) when a player is unable to move, or when a bishop must be placed but there is no empty square left.
