[2p2J]

Standard play pf. I like a continuation stab on the flop after he checks, hes showing weakness after limping pf. If he calls a bet your probably behind most of the time. If he checks again on the turn you have a weird spot hitting the ace. In this type of situation are you looking to play a medium sized pot or large pot? Depending on how confident you are in your hand I would base some of your action off that. When I first looked at this hand his line didn't make since but if I were to put him on a range it would be J10, 77, and the least likely 55. In any case a fold isn't bad here with one pair.
