5/10 with 200 BB stacks, 2 pair becomes a pure bluff

[Jonny]

Villain in this hand is LAG preflop, and hasn't really been out of line postflop so far. I know he will autobet the flop here.

Preflop: Hero is SB with T[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/spade.gif[/img]. Hero posts a blind of $5.

Hero checks, <font color="#CC3333">CO bets $70</font>, <font color="#CC3333">Hero raises to $200</font>, CO calls $130.

Dangerous board, he will autobet, I think this street is standard. I want to take it down now.

<font color="#CC3333">Hero bets $350</font>, CO calls $350.

Plan here is to try and get him to fold overpair, my plan is to check/fold if called here.

Change of plans. I have him on overpair with a heart after his turn call. I figured I was representing either a flush or Jacks up on the turn. No way he can call here. Or can he?
