A chancellor (also known as empress, marshal, knook or elephant in is a fairy chess piece that is a combination of the rook and the knight. Although it cannot jump over other pieces when moving as a rook, but may be considered to do so when moving as a knight. The chancellor is one of the most popular chess variant pieces, like the archbishop.


The chancellor is one of the earliest described unorthodox pieces and has gone by a number of names since it was created by Benjamin R. Foster in 1887 in St Louis.

The piece appears in many fairy chess variants, for instance the more popular Capablanca Chess and Gothic Chess.


Movements of the chancellor.

The chancellor is closely equal in strength to the Queen, despite the queen usually getting the upper hand in the endgame (with few pieces remaining). However, the chancellor can achieve a draw more easily because of the greater number of check possibilities. Usually, trading a queen for chancellor is considered bad trade, but the difference might be hard to exploit with several pieces remaining on the board.

Depending on the board size (in this case 10x8), the queen is assessed to be about 1/2 points stronger than the Chancellor, essentially meaning 1/16 (theoretically) more powerful in most practical circumstances. Queen: 8.8 Chancellor: 8.3
