Uri gave one good answer to your question already IMHO. There are others: I don't think Kramnik would work out "hooked" games like 2100 rated amateurs looking for book holes in the first place. When he reaches a position he judges as clearly superior for him he will stop at some time, he has good reason to be confident in his general abilities. Yes, I do believe he had this exact position on board in preparation (because of ultra-fast early play) and taking a longer time for a key move is of no relevance. I remember a few games Karpov-Kasparov commented by both where both mentioned what they had on board in preparation. And while they had worked the lines out all in advance, they took a long time at several points, making sure their preparation was right, looking for even better ways to make progress, thinking about possible surprising moves by their opponent etc. Or think of today's endgame. Did you notice just _how_ slowly Kramnik played those really simple final moves? I don't know how to avoid to sound as if I made an accuse here. This is not my intention at all - believe it or not.
