What's Wrong With This Statement?

[Brineboitano]

One thing I don't understand: if you're including the slight possibility that you will win an uncontested pot after it checks around twice, why do you NOT include the possibility that someone who you might have bluffed out will then bet you out of the pot after you check? Depending on the game, the probability of being bet off the hand by somene elses bluff might outweigh the possibility that you draw to the best hand.

You make a good point about not simply making a play because it has positive EV, but there seem to be too many factors to this problem to make the answer completely straightforward.
