Live - NL200 - 88 from SB

[Spurious]

I am not a regular at this game, as a matter of fact i played there the first time.

The hand:

NL200(max. BI 200) - 8handed

Everyone got at least 70BB (cant remember the exact numbers).

UTG (weak player, limped a lot and folded to a raise) limped, MP (mixed it up between limping and raising, not a tricky player) limped, BTN limped (he was shortstacked and rebought twice for the minimum), I wake up with 88 from SB.

I raise to 12. I decided to raise because raises were respected and players often limp/folded. I was OOP but i thought i might take it down right here or HU with a Cbet.

BB (sat down recently, didnt know much about him at that point) called my raise, UTG and MP as well, BTN folded.

The flop comes (Pot: 50$):
7 [img]/images/graemlins/spade.gif[/img] 3 [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/spade.gif[/img]

I bet out 30$, BB calls, rest folds.
I bet out because i thought i might have the best hand here and the flop missed most hands.

Turn (110$): 5 [img]/images/graemlins/diamond.gif[/img]
I bet out 40$, and BB calls again.

Now i start to wonder what hand he could have. Since the board is extremely drawy he could have a FD.

River (190$): J [img]/images/graemlins/diamond.gif[/img]
I decide to check, and he almost instapushes with his last 65$. I think for a minute and fold.

I think folding was correct, but what hand could he have?
77-TT(JJ) might play that way. Maybe A7s.
