I did not claim that it is wrong that 2457 player can calculate things better than me but it does not mean that I cannot have an opinion that something is impossible to calculate for humans because the number of lines to prove it with a computer is too high. It does not mean that the decision of the human to sacrifice was wrong decision. Chess is a practical game and decision to sacrifice for the reason: "if I can not see defence for the opponent then there is a good chance can be correct practical decision and tal is known to play sacrifices based on this reason and the fact that part of them were in theory wrong does not change the fact that it was good practical decision to play them.
