UTG had 5[img]/images/graemlins/heart.gif[/img] 2[img]/images/graemlins/club.gif[/img] and LOST (-$0.75)
BB had K[img]/images/graemlins/heart.gif[/img] 7[img]/images/graemlins/heart.gif[/img] (a pair of Sevens) and LOST (-$19.20)
sirklas had A[img]/images/graemlins/diamond.gif[/img] A[img]/images/graemlins/club.gif[/img] (a pair of Aces) and WON (+$18.75)

My image at this tables was a 24/17/3.1 .
BB was a 34/14/4

He had been very loose in the last hands and made some mistakes. When the 9 [c] appeared on the turn, Flush and Straight were possible, and I was angry to bet. I was surprised that BB checked before me. When I considered his stats, I put him on a pair or on a FD or SD on the turn. I indicated his IACR as weakness and called.

I would like to know your oppinions on this move and how I played that hand.
