A lot depends on the era you're talking about, for computer chess. It used to be that forcing a chess computer out of its "book", so that it had to start relying on move-tree searches much earlier in the game when that tree is still monstrous in size, was a good or at least OK tactic. As the computers got better, and as more effort was put into anti-anti-computer tactics, it stopped being useful, but to say that this is "not at all" how computers have played chess is incorrect.
