My thoughts:
pre-flop is standard
flop, to deny flush chasing I should raise more, but I am WA/WB more often so I am comfortable with this
turn, this screams made flush to me, but I call because the bet sucks and I can fill up
river, horay I fill up... WTF is he doing? I suddenly worried about a bigger boat so I call. In retrospect I should only worry about 77, 88, 78 therefore push all my chips in. agree?
