Would really like to see the 2NT hand. This opening after P-P-P is very dangerous. 2NT played with a dead dummy is odds on to be down one or two or on a bad day more. So we must assume the 2NT is very close to the ole fashion Goren Demand 2C bid promising 5+ sure tricks. West very likely had a 3C preempt and for some reason did not make it at his first turn to bid. West will have the missing honors in the club suit and most likely a 9 or 10 card fit with east and I'm guessing west started with 8 club cards had a cramp and could not get the 5c card to the table. So we could be dealing with anything here from a DBL and set to an easy save in 6 of a Major. I will side with the other entries here because we probably are playing against a pair we haven't seen before. And, at the 6/7lvl if it is a bad slam you will gain most Matchpoints by playing good defense without adding in the DBLE. Pass is a real good choice. Now for the however. to be a non stoppable slam, east has to hold both the A Q or the A10x of clubs and must be able to communicate with the west hand in order to run a finesses; barring that you are guaranteed two trump tricks if nothing else. So no one can complain if you go for the Matchpoints and DBLE. That's at Matchpoints or maybe BAM or IMPs In any team event. Pass is very solid and very required. The potential loss in a team event far out weighs any possible gain.
