Progressive Mutation Chess

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

Mutation chess played progressively. This is the popular way to play Mutation Chess. Remember that a queen move to an empty square, or capturing a queen, is illegal if it gives check. This is Scotch-style progressive chess, so a check ends your turn. You must get out of check on the first move of your series.
