Call turn w/ 2 pair when obvious draw hits?

[rathsa22]

CO is unknown, just sat down. SB is LPP after 50 hands, nothing really out of the ordinary.

Preflop: Hero is Button with 2[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/diamond.gif[/img].
UTG calls, <font color="#666666">5 folds</font>, CO calls, Hero calls, SB completes, BB checks.

Any arguments for a raise here after 2 limpers?

Flop: (5 SB) 8[img]/images/graemlins/club.gif[/img], 2[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, BB checks, UTG checks, <font color="#CC3333">CO bets</font>, <font color="#CC3333">Hero raises</font>, <font color="#CC3333">SB 3-bets</font>, BB folds, UTG folds, CO calls, Hero calls.

At this point, I put the SB on a flush draw, A8, or a set.

Turn: (7 BB) 7[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">SB bets</font>, <font color="#CC3333">CO raises</font>, Hero folds, SB calls.

I would have called one bet here, but I'm only getting 5:1 after the raise -- and not closing the action.

River: (11 BB) K[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
SB checks, <font color="#CC3333">CO bets</font>, SB calls.

Final Pot: 13 BB
