Preflop: Hero is CO with A[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/club.gif[/img].
UTG folds, <font color="#CC3333">UTG+1 <font color="#A500AF">(LA-P)</font> raises</font>, MP1 folds, MP2 folds, MP3 <font color="#A500AF">(LP-P)</font> calls, <font color="#CC3333">Hero 3-bets</font>, Button folds, SB calls, BB folds, UTG+1 <font color="#A500AF">(LA-P)</font> calls, MP3 <font color="#A500AF">(LP-P)</font> calls.

Flop: (13 SB) 5[img]/images/graemlins/club.gif[/img], 3[img]/images/graemlins/heart.gif[/img], 6[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, LA-P checks, LP-P checks, <font color="#CC3333">Hero bets</font>, <font color="#CC3333">SB raises</font>, LA-P calls, LP-P calls, Hero calls.

Turn: (10.50 BB) 7[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">SB bets</font>, <font color="#CC3333">LA-P raises</font>, LP-P calls, Hero folds, SB folds.

At this point I had someone betting this board, the LA-P raising it and the LP-P cold calling. The LP-P I could care less about, but the bet and raise concern me. What do you think??

River: (15.50 BB) T[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">LA-P bets</font>, LP-P calls.

Final Pot: 17.50 BB
