This kind of thing is usually caused by a parsing error that is due to a simple syntax error. To find out what it could be, I added "list;" to the end of your Pre-Game code and clicked Run. At the end of the first listing, I got this:
907 remind "Enter third leg of move or press Pass;
gosub legalmoves2 KING 2;
continuemove;
elseif sub stalemated king:
endif;
;end;
So, it looks like your remind statement is missing a closing quotation mark. However, looking at your actual code, I don't see it missing.
I would recommend the general debugging technique of cutting or commenting out sections of code to determine which code is causing the problem. If you cut code, paste it back in before cutting more, so that you can later paste back in all that you cut out.
