Your group plays Kontra and the Valat. P1, the Forehand, plays the Call, calls the King of Clubs and announces the Valat. You are P2, and the Skus is not in view.

You kontra only an item you can be sure must fail. Do you say Kontra on the Valat?
Answer
Kontra. Only the Skus beats your XXI, and only the Skus and the XXI beat your XX. The Skus can take one of them, in one trick; the other one then wins a trick for your side, so the Valat must fail. The failed announced Valat gives each Defender 8 Victory Points, and 16 after your Kontra.
Rule: A player who does not believe a contract or an announced bonus will succeed says Kontra, and it pays double (×2).
