Shakari11: checks
Trolleur: bets $17.10
jimmy lee: folds
Shakari11: raises $51.30 to $68.40 (for some reason I got this feeling that he had an awfully big range here.)
Trolleur: calls $51.30

*** TURN *** 9[img]/images/graemlins/heart.gif[/img]
Shakari11: bets $78
Trolleur: calls $78 (Now I just called here because I felt that if I raised all in, I'd only get called if I was truly beat. However, if I didn't hit a full house, on river, I knew I was going to be squirming if he bet)

*** RIVER *** blanks out 7[img]/images/graemlins/heart.gif[/img] - and I'm def squirming when he bets.
Shakari11: bets $309.80
