Pre-flop: (10 players) Hero is CO with J[img]/images/graemlins/heart.gif[/img] A[img]/images/graemlins/spade.gif[/img]
UTG (poster) checks, 5 folds, <font color="#cc0000">Hero raises</font>, Button folds, SB calls, BB calls, UTG folds.

Flop: J[img]/images/graemlins/club.gif[/img] 6[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/club.gif[/img] (7SB, 3 players)
SB checks, BB checks, <font color="#cc0000">Hero bets</font>, SB calls, <font color="#cc0000">BB raises</font>, <font color="#cc0000">Hero 3-bets</font>, SB calls, BB calls.

Turn: 5[img]/images/graemlins/spade.gif[/img] (8BB, 3 players)
SB checks, BB checks, <font color="#cc0000">Hero bets</font>, SB calls, BB calls.

River: 8[img]/images/graemlins/club.gif[/img] (11BB, 3 players)
<font color="#cc0000">SB bets</font>, BB calls, Hero ???

I typically call here HU (which is standard), but do I have a hand to overcall (especially given SB's calling station donk and BB's solid style)?
