we don't know how exactly they select the moves to examine. What they certainly do know is that they don't examine

How do we know this? We don't. We know that they are not concious of the operation going on -- but neither are we concious of the operation of walking. This does not mean that walking somehow occurs without some form of decision making. Whether this decision making is subconcious, proto-receptors, muscular memory, etc it does occur and is still a set of heuristic rules for what to do.

These rules are easily observable in a computer as well as the processing of them. Just because you don't know everything doesn't mean you cannot exclude everything. Suppose I know X was in a house. I don't watch the house, but I do watch the road going south from the house. Now, X is no longer in the house. According to your reasoning saying "I don't know where X went, but I know he didn't go south" is not a proof or reasonable support, but merely naysaying of something, because I don't know where X went

No, you have proof that X did not come south. You do not, in any way at all, have proof that no heuristically based decision making process is going on when a grandmaster immediately prunes his decision tree. You simply have the statement that you don't know what happens.
