Preflop: Hero is CO with Q[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/diamond.gif[/img].
UTG calls, UTG+1 calls, <font color="666666">2 folds</font>, <font color="CC3333">Hero raises</font>, <font color="666666">1 fold</font>, SB calls, BB calls, UTG calls, UTG+1 calls.

if I were MP3, I would just call. in CO, I raised to buy the button, should I just let him and the blinds come along?

Flop: (10 SB) Q[img]/images/graemlins/heart.gif[/img], 5[img]/images/graemlins/diamond.gif[/img], 2[img]/images/graemlins/diamond.gif[/img] <font color="blue">(5 players)</font>
SB checks, BB checks, UTG checks, UTG+1 checks, <font color="CC3333">Hero bets</font>, SB folds, BB calls, UTG folds, UTG+1 calls.

Turn: (6.50 BB) 6[img]/images/graemlins/diamond.gif[/img] <font color="blue">(3 players)</font>
BB checks, <font color="CC3333">UTG+1 bets</font>, <font color="CC3333">Hero raises</font>, BB folds, <font color="CC3333">UTG+1 3-bets</font>, Hero calls.

Should I cap? If I had KJ or KT there is room for another face card flush that I beat.. but not with QJ. I'm not sure how well the flop bet 'disguises' my flush in other players' eyes.

River: (12.50 BB) 3[img]/images/graemlins/heart.gif[/img] <font color="blue">(2 players)</font>
<font color="CC3333">UTG+1 bets</font>, Hero calls.

Final Pot: 14.50 BB
