Drawing at a flush is one of the most tempting money sucks in all over poker. Even when you hit four of the same suit on the flop, more often than not you will miss your card on the turn. You will then have to face another bet (if your opponent is properly representing his hand) and pay further odds to make your hand. When the river comes and still does not complete your flush (again, which is more often than not), you will often be faced with the decision: let the hand go with your missed draw, or try to win it another way: by bluffing.
It can be difficult to figure out if you have any chance at all of making your online poker opponent lay down on the river. If he has been betting all along you usually will have to give him credit for a hand, especially if he is a solid player. If he suddenly slows down on the river and is a timid player it might be worthwhile now and then to try to fire off a bet in hopes that that will be enough for him to forgo the hand.
Ultimately, you have to weigh your odds of how often your online poker opponent will lay down versus how much you stand to gain if you make him do, and also considering how much your bet to make him lay down will cost in the event that he decides to stick around.
