Machine vs Man

A computer could be programmed to handle the extensive mathematics of a Poker game. But the psychological complexities are another matter. A system figured out by computer can beat Blackjack because there the dealer has no options. He has to stand on 17, he has to hit 16.
A computer could play fair to middling Poker. But no computer could ever stand face to face with a table full of people it had never met before, and make quality, high profit decisions based on psychology.
To do that requires perception and judgement. It requires a human mind.
The way I accumulate knowledge of a particular player is by listening to him, and looking at him, instead of talking.
