My experience is that when the key move of a deep 'tactic' is played (the sac), the computer will find the next moves pretty easily, probably with negative eval at first, but climbing on every ply it searches. This is why openingbook-sac's are that dangerous.

This is just not true. Another area where the GM is superior, is in the endgame. I've seen many endgames played by computers that makes no sense at all. Humans can really easily beat computers here. As long as they stay out of the tablebases :-) Richard.
