Preflop: Hero is dealt Q[img]/images/graemlins/heart.gif[/img] A[img]/images/graemlins/spade.gif[/img] (6 Players)
UTG calls $2.00, 2 folds, <font color="red">Hero raises to $9.00</font>, 2 folds, UTG calls $7.00

Flop: ($21) 5[img]/images/graemlins/spade.gif[/img] 5[img]/images/graemlins/diamond.gif[/img] 3[img]/images/graemlins/spade.gif[/img] (2 Players)
UTG checks, <font color="red">Hero bets $14.00</font>, <font color="red">UTG raises to $32.00</font>, Hero calls $18.00

<font color="blue">i called his check-raise because i didn't give him credit for a real hand (would he check-raise trips?). i put him on a flush-draw, maybe a small overpair against which i have six outs.</font>

Turn: ($85) A[img]/images/graemlins/diamond.gif[/img] (2 Players)
UTG checks, <font color="red">Hero bets $55.00</font>, UTG calls $55.00

<font color="blue">i valuebet because i guess he has a flush draw. and now i beat any overpair he might have had.</font>

River: ($195) 6[img]/images/graemlins/spade.gif[/img] (2 Players)
<font color="red">UTG bets all-in for $106.40</font>

<font color="blue">this sucks. but the pot odds are 2.8:1 and it's weekend - people bluff a lot, and possible flushes are a convenient spot to bluff...

can i call this?
should i just shove the turn?</font>
