Many GMs disagree with Kotov's tree of valuations, as it is simply an impractical way of playing. Obviously, you need the calculating ability, but it should be turned only a few times a game.
Instead and this is common to all chess players, most good moves are just immediately obvious. (see Gladwell's Blink, which is true for chess at least).
It has been said, that in a regular chess game, GM might have to have a think 2-3 times a game(see Anand in top form), IM 5 times, an FM 10 times.
As an FM I have to concur with this. When playing a GM, I invariably make a mistake when I start running out of time, as my store of "obvious" moves is much smaller than GMs.
Perhaps I have only 10k positions stored in my RAM, and GM has 100k.
On the other hand when playing say a candidate master, I see them think long and make a mistake, which seems obvious to me immediately.
Still there are players who are more of a calculating type(see Shirov, Kasparov), and some who are less(say Botvinnik, Karpov).
