Deceptive plays have value when being deceptive prevents your opponent(s) from defining your hand and therefore playing correctly against it. There is no point in being deceptive if your opponent can't read the situation anyway or would play incorrectly even if he knew your holding. That might be due to a lack of your opponent's hand reading ability or deficiencies of his play knowledge; but it is also becomes [sic] the case when your hand range widens and even quality hand readers wouldn't be able to narrowly define your hand.
