Which card makes sure the team wins this trick?
Answer
The XVI. You have no Club, so you must play a Tarok, and the Dapper’s XIV is winning. The XVI beats it, and only teammates play after you, so the trick is the team’s. With the XI you hope that P5 or P6 trumps higher, but either of them may still hold a Club and have to follow suit.
Rule: You must play a Tarok. You don’t have to win the trick, but you may not play another color suit.
