Got it. Couple of more problems, though

I made the correction you gave me, and it solved that problem.

I just found two more (I should have kept testing yesterday but had to logoff)

White: a1=r b1=n e1=k
Black: (none)
Move e1-c1 OK (should be illegal: White knows there is a knight there)

White: a1=r e1=k
Black: g6=b
Move e1-c1 OK (should be not possible: White does not know about bishop)

I updated "Driver plus real code" with the correction and a slight change to the driver. Please do me a favor, use "Driver plus real code" to fix the problem and when you're finished, post the result as a new thread entitled "Logic module" or whatever. I will remove references to the integrated demo from the status and refer to the new thread instead.

Thanks!
