Multi 2 diamonds

Multi 2 diamonds, or simply Multi, is a contract bridge convention whereby the opening bid of 2 shows multiple types of hands, which always includes a weak-two bid in either major suit, while the additional meaning may be a strong balanced hand (commonly 20-21 high card points), or a 20-22 three suiter. The inherent ambiguity as to both suit and strength makes it a powerful and popular convention capable of seriously disrupting the opponents' bidding.
