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.

Russian Progressive Chess

If you had a Java-capable browser, you could play Russian Progressive Chess here.
Keys "s"=save "l"=load "b"=back once

White plays one move, then Red plays one move. White plays two and then Red plays two. And so forth. On each odd-numbered turn except the first, your last move must move one of your opponent's pieces. Move a difference piece of your own each time as long as you can.
