That's not a lot of missed 3NT. It's a few where it has play, plus you will get to a load more that have zero chance.

♠xx ♥Qx ♦Txx ♣KQJxxx is not a preempt opposite a 1♣ opener. It's good mixed raise. Why would you get to loads of 3nt with zero chance ? Partner should be mindful that a mixed raise can be on ♣ length or a distributional hand with minors, so he won't be trying for 3nt on hands with lots of high cards unless they included Aces as in my examples.

I think you are confused. Where did I say this hand was a preempt? For me it is a down the middle 3♣ bid. Preemptive raises to 3m in comp are for children.

I would estimate that the chances of 3nt making opposite a weak NT are less that 1 in 10, so inviting just does not stack up. Cue should invite 3NT opposite decent 14s and good 13s - not the absurd perfectos you gave. But you are are arguing against the world - everyone who has expressed an opinion thought East was crackers, and not just because of the final pass. This just ain't a good raise.
