I’m not sure I get the question. In poker you don’t announce your cards and don’t reveal your hand until the end of the round. Though part of the game does involve deception, as trying to make the other players think you have a better hand than you actually do is a common tactic. This itself is a gamble, however, as it often involves risky bets that will hurt you if another player “calls your bluff” (re: raises the stakes by betting even more). However there’s no lying about your cards, as you never actually say anything about your cards.
