You are on the backup site for 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.

Fischer Random Chess

D. Wheeler on Fischer Random Chess and Full Chess. This applet follows Wheeler's castling rules which he says are standard, i.e., kings can castle across occupied squares. This seems to be still under discussion (7/23/03) as Wheeler confirms.

Full Chess is the same game but with no castling across an occupied square.

7/27/04: There now seems to be agreement that true "Fischer Random Chess" does not allow a king's leap, as this applet does.
