You are on the backup site for Chessvariants.com. Any posts, moves, or other changes you make here will not be permanent, because the pages and database from the main site will be backed up here every midnight EST. Additionally, things may not be working right, because this site is also a testbed for newer system software. So, if you are not here to test, develop, or merely read this site, you may want to change .org to .com in the navigation bar and go to the main site.
Recent versions of Chrome, Firefox, and Edge do not support Java. Internet Explorer and Safari should still support it. Besides that, recent versions of Java will block this script unless you add https://www.chessvariants.com to your Java exceptions list. You should find this in the Security tab of your Java control panel.

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.
