A WSOP Main Event Hand

[slickpoppa]

I've been meaning to post this one for a while, here it is:

250-500 blinds, 50 ante. It is about 1:45 in the morning and we are playing until 2:30.

I have about 18,000 and I have tight table image. I have only played one hand to a showdown and it was when I took out a small stack with QQ.

I get KcJc in UTG+1 and raise to 1500. This is a marginal hand for EP, but I raised since play was tightening up because it was late and getting close to the second day.

It is folded to the BB who calls. I don't have much of a read on the BB other than that I suspect he is loose passive. He has about the same number of chips as me.

The flop is K T 5, all hearts.

BB checks, I bet 2500, he calls.

The turn is 4, not a heart.

He checks, I...? (There is ~9,000 in the pot and I have 14,000 left)
