Preflop: Hero is SB with 9[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/diamond.gif[/img].
<font color="#CC3333">UTG raises</font>, <font color="#666666">5 folds</font>, CO calls, <font color="#666666">1 fold</font>, Hero calls, BB calls.

Flop: (8 SB) 4[img]/images/graemlins/heart.gif[/img], 2[img]/images/graemlins/club.gif[/img], 7[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>
Hero checks, BB checks, <font color="#CC3333">UTG bets</font>, CO calls, <font color="#CC3333">Hero raises</font>, BB calls, CO calls, <font color="#CC3333">Hero 3-bets</font>, BB calls, CO calls.

The UTG went all in, (my raise looks confusing)I 3-bet, hoping to drive players out and maybe win a side-pot even if UTG has a higher PP.

Turn: (10.12 BB) 6[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(4 players)</font>

River: (13.12 BB) 5[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">Hero bets</font>, BB calls, CO calls.

Final Pot: 16.12 BB

Should I have checked the river? It sure doesn't look like I'd be good.
