I have a deal like this: S: Kx H: AKxx D: AQJxxx C: A We play 2/1, if the bidding goes as following: 1D-1S 2H-2S my partner's 2S only promise 5+cards and 5-9HCP; How can i show my extra values, slam interest and try to find best contract, or i have better treatment than this reverse bidding process to describe my hand?
