2 limpers to me, I'm in MP with 66, I limp, button calls, SB calls, BB checks.

Flop: [6h Jh 10c]

Checked to me I bet, folded to button who raises, folded back to me I 3-bet, button calls. I suspect he's on some kind of draw either hearts or straight.

Turn: 3h
Great hearts got there.....

Here we go, I bet, he raises...super, I'm pretty sure he has hearts....I called.

River was a blank. I check called on the end to see his Kx hearts.

Did I play this ok? I wondering if I should have done anything differently.
