say that in reality, the computing power does not depend on the status of each, and it is true. What happens is that the stronger players are better able to rule out moves that you know are wrong, allowing them to reduce potential arc at each position, allowing them to increase the depth of calculation. In contrast, the weaker players are forced to calculate a potential arc wider and therefore more difficult to calculate. So, your computing power has much to do with how many sequences have already memorized precomputed so to speak. In these "sequences" and we call tesujis precomputed in Japanese, Korean haengma (행마), and are extremely practical. But this series of little tricks have a small problem. Often, we got used to recognize the positions in which they can apply tesujis but sometimes we overlook the fact that certain sequence should not work for the enemy if it works because of a stone that we are not taking into account, which usually lead to disaster. I will give you an example:

5 th round of the Barcelona tournament this year. I'm white. My opponent, a French 2d which had already played earlier in Paris. White has just played just 1 to reduce the influence of black when it strikes with 2.

tesuji standard starts to cut the target area, without paying much attention to the marked stone, which seems to have no influence on the sequence.

Jumping in A, black bears in mind this sequence, which is clearly favorable for black. Because white can not cut into 1, as evidenced by this sequence, the situation seems to favor black, but ...

Black has not taken into account the effect that the marked white stone is in the sequence, and is surprised by the movement of white 1. Up to 5, black is captured. Yes, I know, the fight seems complicated. I invite you to try for yourself. Sure you will reach the same conclusion we reached my opponent and me.
I leave the whole game if you want to see. Obviously, it is commented.
