If u put a player on a possible draw here (the flop) ... should u be 3-beting? or wait for a turn check raise when a blank hits? well thats what i was going to do but when the 3rd flush card dropped I didn't know how to play it and called down like a bum. Would i be right in thinking this turn is the perfect candidate for a bet/fold?
