Since Java is no longer supported in most browsers, our Java applets probably will not run unless you install an extension that will run them. We recommend installing the CheerpJ Applet Runner extension on Edge, Chrome, or another Chromium browser. If your browser still does support Java, and you're not using this extension, make sure this site is listed in your Java exceptions list. You should find this in the Security tab of your Java control panel.

Chess Variants

After you move, you designate an empty square that the opponent may not occupy. The program requires you to do this. The same player may not designate the same square on three successive turns. D. B. Pritchard, 1989.

There is another version in which the barred square may not be crossed. I do not know whether it is lawful to escape check or mate simply by barring a square.

These are simple illustrations rather than strong opponents.
