Hmmmm, there's no way I was right about the CO now. He didn't have the set, otherwise he would have certainly reraised the turn.

Time to rethink:
He's a tight player.
He limp-called pf (which led me to believe he had a mid-pp)
Check the flop.
Bet the turn, which could have meant a number of things.
Thought and called a raise, which means he did not have a made hand to protect against the numerous draws, rather he had a weak hand or was on one of those draws himself.
The river is a brick.
There's nearly 10k in the middle.

I'm taking a stab at this pot. Bet 3,500$, trying to make it look like I have a hand and want a call.

If he has 77-88-TT, in line with my PF read, a tight player will probably muck it, unless he has a read on me.
if he has AJ himself or some other hand for a missed draw, I would expect a fold as well.
