50 NL - Top pair against a Limp Caller's 3 barrel

[TheBobn]

Villain is Heiko62, Villain is 55/15, i have about 200 hands on him, this is his 52nd hand at the table, he was running pretty hot from what I'd seen
Agg of: 2.47/1.38/7.25

My image: I've been fairly active at the table preflop, although I don't have numbers, id guess between 18/16 and 24/22, with moderate aggression, the table was very station-y and I was only cbetting flops I hit or intended to two barrel against certain villains.

My comments on the hand: This is either 33, 44 or 66 or air, I think its unlikely he shows up with a better king after limp calling from the CO.
He also shoved the river pretty quickly. I'm not too happy about calling the flop and turn and folding the river, I feel like the decision should be made on the turn given the fact that the decision is still difficult on a river blank.

Anyways, any comments appreciated.
