Fish limps Utg, 1 more guy limps, I make it 55 with 68ss, folded around to Utg who makes it 155. I call and v r heads up to the flop. Stacks are 2600 deep.
Flop is K79hh and 1 spade. He checks, I bet 200, he makes it 400. His hand is face up here as kings. I elect to call. Turn is As. Gives me a fd and open ended. He bets 400 again, I call. River is the 6h. So the board is k79A6 3 hearts on the river. He checks, and I elect to jam. He eventually calls with set of aces.

Thoughts?
