Do you say Kontra? You kontra only an item you can be sure must fail.
Answer
Do not say Kontra. The Moon loses only to the Skus, but it is your only Tarok: if the Forehand leads the Skus to the first trick, the Color Rule makes you play the Moon under it. Your Kings win only if their suit is led and nobody trumps, and the Declarer chooses every lead, so nothing in view proves the Valat fails.
Rule: If you believe that the Declarer will not deliver the contract, you may say Kontra; here you say it only when the cards prove it.
