Anyone let this go?

[PlayerA]

This was from UB and I didn't cut and paste the hand history. So, I'm going from memory. It's a .50/1.00 and is loose and passive. I'm in the cut-off with KTxx (other cards irrelavent). A couple of limpers ahead. I limp. Button limps. I have about $100, the button has about $140.

The flop is KTx (where is the x is a little uncoordinated card). Checked to me. I bet the pot (5 or 6). Button calls, all others fold.

Turn is T. I pot. Button calls.

River is Q. I bet about half-pot and get raised. I call.

Of course, he had the KK.

This is a situation that does come up from time to time. I've been on both sides of it. Anyone here play differently or get away from this hand?
