cold callers driving me nuts.

[bigalt]

I've been really stuck with what to do about people calling behind me, playing the hand as the aggressor OOP.

Example:

Hero has ATo in MP.

preflop:
EP folds, Hero RAISES, CO folds, Button calls, blinds fold.

Flop: J 6 2 rainbow
Hero BETS, Button calls

Turn: 5
Hero ???

I am running into this situation a LOT at the baby limits I've been playing. What kinds of villain tendencies would encourage you to take what line?

are our only two decisions bet/fold and check/fold?
