NL25: JJ bluffed out on the river??

[King Car]

Villain's 3rd hand at the table. Saw him play one hand, after posting he called a 4x raise with J3 and proceeded to call down an u/i AK on all streets after flopping a 3.



Is this a worst hand enough of the time to make a call profitable???


Weak fold??

Looks good to me.

His preflop calling range is huge, based on the hand you described, so he could easily have a four in his hand, calling you down on the flop and turn. I don't think he has just a pair of kings here, as he would likely check-call the river.

You need to be have a winner roughly 1/3 of the time on the river, so it's close, but I still lean towards folding.
