I just remembered. When I had Windows 3.11 I had Chessica and CM4000
installed. And I was able to play the two against each other. I would
just leave them both booted. After one program made a move I'd just hit
alt-tab and up pops the other program. No problem. In the beginning
CM4000 would always beat Chessica very easily, even when CM was moving
at less than 10sec a move and Chessica took about 3 minutes. What is
strange {after writing a nasty letter to the seller) that when I reduced
the hash in Chessica it played very much better. The lower the hash, the
better it played! I don't know. It might have had something to do with
the Window 3.11 memory. Other programs worked well also. Fritz4 would
not want to calculate, but you could move manually without analysis. I
think I was able to  use Genius also.  Anyway, it is possible with some
programs.
