Pre-flop: (5 players) Guruman is SB with 7[img]/images/graemlins/club.gif[/img] A[img]/images/graemlins/club.gif[/img]
2 folds, <font color="#cc0000">Button raises to $1</font>, <font color="#cc0000">Guruman raises to $2.25</font>, BB folds, Button calls.

Flop: J[img]/images/graemlins/club.gif[/img] 2[img]/images/graemlins/club.gif[/img] Q[img]/images/graemlins/diamond.gif[/img] ($4.75, 2 players)
<font color="#cc0000">Guruman bets $3</font>, <font color="#cc0000">Button raises to $9</font>, Guruman...

so I should be repping a pair most of the time with this line, but button's raise signals that he's committing himself here. I clearly can't continue unless I have fold equity on a push because I don't have immediate odds to draw to the flush. Also, villain could be making a play with a worse flush draw.

Easy fold?
