"REBUY!"

[LearnedfromTV]

Pokerroom 10K guaranteed. 20+2. Unlimited rebuys. Second level in the rebuy period. I've already cut my 3000 (rebought immediately) in half and doubled it back, first with straight v flush, then set v overpair. Villain rebought to start and hasn't done much since.

PRE-FLOP
2 limpers to Villain, who raises to $325 (!), fold, fold, Hero calls (?). Everyone folds. We're headsup.

Hero bets $550, Villain calls $550.

The combination of the too large preflop raise and then just the call on the flop leads me to think there's a good chance he doesn't have a big pair, but to be honest I'm a little confused.

I have ~2500 left, Villain has ~2300.
Now what?

I chose what i think is the best turn line but I want to hear a few opinions before I post it and my reasoning.
