I saw this chart one time that had the probability a guy is bluffing compared to his age. I saw a pot this week where a young hot shot didn't last so very long.

He sat down for $500 and played super tight, thinking chip tricks had something to do with the game.

Finally he caught AK and raised and caught a few callers. It came A, 10, 3 rainbow. A guy who all the regulars are totally certain bets only the near nuts leads off with $150. This guy never bluffs. He does not bet on a single pair. He is the world's tightest calling station. The young guy moved all in and ran into A,10.

It is hard to lay down a fifth street bet when you cannot put them on a hand. Sometimes you have to just think they must know what they are doing.
