The Commodore piece was invented in 1936 by
The Commodore is a very interesting piece for the tactician. Positionally, too, it could be quite dangerous because one can sometimes sacrifice a Commodore for a light piece (Knight or Bishop) to achieve positional ends. In the middlegame the Commodore is more valuable than a Rook, due to its dangerous tactical capabilities. But in the endgame it is less valuable than a Rook. An obvious case is the endgame King + Commodore vs. King, while it cannot give mate to the enemy King.
The following preset makes a good validity check of Commodore moves, etc. Moves are automated, including castling and the 'en passant' move. Pieces can be moved by pointing and clicking. When promoting a pawn, it will automatically turn into a Queen. Should you prefer another piece then you must type it manually (e.g., add N a8; capture a7). (If you wish to promote to a Commodore you must use the internal syntax Q1.) Use small piece-letters for black. E-mails to your opponent are generated, but you can play online by intermittently pressing the browser's update button.
You can download a Zillions implementation here.
