Well, first of all there would be a big difference as Shredder would be running on at least 4 fast processors if not 8 or more. Also in that case it will be using a specific secret book to avoid Kasparov to know in advance what Shredder would play and specifically made for that match. All this together would make a big difference as the CB version is commercial and does include weaker variations to have a more variable moves/lines selection. This is a specific commercial need which weakens the program in some games and if the opponents know what the program would play Shredder would be handicapped by this.
