anybody know the game Challenge?

this is the greatest game, everybody posts a fixed amount, posts 3 cards. there's 4 rounds-- 1,3 are low rounds, 2-4 are high, if you think you have the best hand that round, you place out 2 of your three cards face up, and others can declare "challenge." or they can "rechallenge you." and double the bet.
