Villian is pretty loose and will go to river with low pocket pairs on previous hands I observed.

Preflop: Hero is MP1 with Q[img]/images/graemlins/club.gif[/img], K[img]/images/graemlins/diamond.gif[/img].
UTG calls, <font color="#666666">1 fold</font>, <font color="#CC3333">Hero raises</font>, MP2 calls, <font color="#666666">1 fold</font>, CO calls, <font color="#666666">3 folds</font>, UTG calls.

I think this raise is standard. My hand is probably way ahead of the garbage these guys go to river with.

Flop: (9.50 SB) T[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/heart.gif[/img], J[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>
UTG checks, <font color="#CC3333">Hero bets</font>, MP2 calls, <font color="#CC3333">CO raises</font>, UTG calls, <font color="#CC3333">Hero 3-bets</font>, MP2 folds, <font color="#CC3333">CO caps</font>, UTG calls, Hero calls.

Turn: (11.25 BB) 7[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(3 players)</font>

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

Bet and called a raise. Probably same hand or villian has a set. Thanks for any thoughts on this one.

Final Pot: 23.25 BB
