Live 200NL OOP Set w/ Tricky Turn

[Tablerat]

Main villain in hand is somewhat loose and passive, but does not get too out of line. My image is tight, straightforward.

I have 77 in MP. My stack ~ 350; villain covers.

EP shortstack raises to 20, I call, villain on button calls.

Flop: A [img]/images/graemlins/club.gif[/img] 7 [img]/images/graemlins/spade.gif[/img] 9 [img]/images/graemlins/spade.gif[/img]

PFR bets 25, I raise to 100, button stalls for about 30 seconds and finally calls (I expected a fold and did not think he was acting.). PFR calls all-in (I wasn't concerned about PFR - for some reason put him on an ace the entire hand).

Turn: 6 [img]/images/graemlins/club.gif[/img] (Pot is ~360, I have 230 left)

So, I'm first to act against button, with one player all-in.

The reason I'm posting this is b/c I was 90% sure I was ahead on flop, but felt button was drawing based on his behavior. No clue which draw though on flop (with his wide range esp. on button)!? So now the turn completes one draw and brings another. I was confused as how to play OOP. Thoughts?
