The GUI would be different. The opening book typically supplies 15-20 moves. That is typically 50% of the _entire_ game, since most games are decided by move 40 (perhaps leaving some mop-up to go of course). Isn't 50% a major contribution? Isn't using that in more than one engine very much like using the _same_ engine for half of the game??? >> >> >>>>Of course ICCA can't send you to jail if you break their rules :-) But they can >>>>chuck you out of their tournament.
