A quick take: > reasonable possibilities are too many to analyze, one is forced to pretty much guess. You could say the same thing about chess, but an experienced player wouldn't, because they know which candidate moves are reasonable and which lines to delve into through intuition shaped by experience. Similarly, you might say the same about poker. The possible hands your opponent has are actually quite large, but a…
> You could say the same thing about chess No, chess is on the opposite side of the spectrum! In chess, at all times you have perfect knowledge of the entire state of the board; in poker, you know 2 cards.
That is because although chess appears to be a game of perfect information, it is impossible to calculate anything but a small fraction of possible future game states in a limited time. So skilled chess players must make educated guesses as to which lines are worth calculating, whether their opponent has already studied the current line, and what moves to play to get them out of their memorization.
This is effectively a game of limited information where solid Bayesian reasoning wins, just like poker.
