> I mean, much of the video talks about how it's impossible to calculate all the future moves like in chess, yet move 37 of a possible ~300 move game is called out as genius, and move 78 is a God Hand.

Every move is a choice of ~300 possibilities, and you need to calculate far ahead to know if it's a good move or not, so the number of choices you have to explore is much greater than what it seems.
