The casino gambler who wandered into the poker room is not folding two pair. Not on the flop, not on the turn, not on the river. He "had two pair, what was I supposed to do?"

Why they do it

This player treats poker like a slot machine. Once he connects with the board he's committed. There's no folding range once he has a piece. He's not thinking about what you have - he's thinking about what he has.

The adjustment

Get it in fast with your strong hands. Don't slowplay trying to build a pot - he'll build it for you. Just make sure you have the goods before you go to war.

What it's worth

Slowplaying a set against this guy and losing value because the pot stayed small is a session regret you don't need. Play fast. Get paid.
