Pre-flop: (6 players) Hero is UTG with J[img]/images/graemlins/heart.gif[/img] A[img]/images/graemlins/diamond.gif[/img]
<font color="#cc0000">Hero raises to $1.75</font>, 2 folds, SB calls.

Flop: A[img]/images/graemlins/spade.gif[/img] J[img]/images/graemlins/spade.gif[/img] 9[img]/images/graemlins/heart.gif[/img] ($4, 3 players)
SB checks, <font color="#cc0000">Hero bets $3</font>, <font color="#cc0000">SB raises to $6</font>.

His C/R was instant. He is 28/10/.44/72 hands
Is this a call to let him lead turn into me, or a raise due
to the draws on the board?

thanks
