Round one, seven players. Your hand: Skus, XXI, XX, XIX, XVIII, XVII.
Do you call Solo, or wait for the Dapp?
Answer
Call “Solo!”. For a Solo you should hold three or more Taroks from the XV up. You hold six, and they are the top six cards of the deck: nothing can beat any of them, so all six tricks are yours exactly as dealt. The Solo column always has the highest value, a Solo cannot be Challenged, and the untouched Dapp joins your pile at the end, pips and all. Waiting for the Dapp trades all of that for an exchange you do not need, and an earlier player may claim first.
