You are P2 and opened with Two. P3 bid One, and P4 and the Forehand passed, so the bidding comes back to you.

Do you pass, say "I hold" and take the One, or bid Solo three?
Answer
Pass. Standing is legal here, because P3 sits after you, but holding means that you play One. You hold six Taroks with two big ones, the Skus and the XVI: that meets the test for Two, and One asks for one big Tarok more. Hold only a contract your cards meet.
Rule: Climb to Two, One or a Solo only as your Tarok count climbs past five and then six, one extra big Tarok per rung as the price of one fewer talon card.
