OK...let's do a flush draw. You have T [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/diamond.gif[/img], board is A [img]/images/graemlins/diamond.gif[/img]Q [img]/images/graemlins/spade.gif[/img]4 [img]/images/graemlins/diamond.gif[/img]2 [img]/images/graemlins/heart.gif[/img].

There are 9 diamonds left in the deck and 46 unknown cards. So you have a 9/46 chance of hitting.

Your friend is confused about counting outs because your opponent might have one of your diamonds?

OK...he MIGHT have one of your diamonds. He MIGHT have two of your diamonds. He MIGHT have none of your diamonds. You have no idea what he has, so you just have to count the cards your opponent has with what is left in the deck.
