This was probably the first chess variant, ever implemented on a computer.
The applet checks legality of moves according to the variant, except that
promotion is only to queen. (There is no castling and pawns never move more
than one square.)
Right click on the image to go back to the original setup.
- To make a move, first (left) click on a piece, and then on its destination square.
- To deselect a piece, (left) click again on the selected piece.
- To castle, (left) click on the king and then on its destination square.
The rook moves automatically with it.
- To go back to the original setup, right click on the board.
- The applet checks legality of the moves, including check (with a few exceptions:
see `known bugs'). Also, it enforces that white and black
alternately make a move, white starting the game.
- The applet does not determine stalemate or mate, draw by repetition, or draw by the
50 moves rule.
Version
This is version 0.03.
