Courchevel is a variant of Omaha. What distinguishes him is the flope of a single card that is returned after the blind, and the fact that each player receives 5 cards initially.
Indeed the first flop card is turned up and the first round of betting occurs only after seeing it. The game then continues as a classic Omaha. The two remaining cards forming the flop are turned up after the first round, then are turned up the last two cards. It can be used teo cards from the flop.
