Seven players, round one, and you speak second.
Your hand
What is your plan for this hand?
Answer
Pass now, and pass again in round two. Four Taroks look worth a rebuild, but the XVIII is a trump stop only with four other Taroks beside it, and you hold three, so you have no trump stop. Without a trump stop, pass. You hold one Tarok from the XV up, so a Solo is out too.
Rule: With a trump stop on the ladder, the trump-stop duty can force you to bid, and that is also the hand worth claiming voluntarily, because the twelve-card exchange rebuilds the hand around the trump stop; without a trump stop, pass.
