"Surprisingly, by move 16 Deep Thought had a chance to make a sacrifice that would have placed Anatoly under tremendous pressure. Had the game been played with a regular time control, then Deep Thought would have made the sacrifice. The 3-workstation version of the program that played Garry potentially could find the sacrifice within the game time, assuming that we had got it working for the match. It is amazing how a minor difference could have changed the history dramatically. Since Deep Thought could not find the sacrifice over the board, it played the second best move and Anatoly obtained a slight edge."

Are they missing something, or is there a mistake in the book?
