its a tuff situation were u positive ur hand was best on the flop? thats wat im thinking. u might not of even been best on the flop. well if u thought u were best on that flop u gotta bet more i dont see y u would wanna slow play it wen ur hand is so vulnerable....

mayb he turned a sf on the turn? 34s mayb he had a sf on the flop? 78s

anyway mayb had k9 or a9 or sumtin n u didnt pay enough for him to draw wen u had the best hand
