Replacement for gambling 3NT?

[phil_20686]

I have never heard of anybody play it as a solid major.

 

For a while our system notes had it as the equivalent of 8 solid. E.g. AK to eight and an ace, or KQJ to 8 and an ace. Not quite so restrictive, but not so far away.

 

Then we moved to more flexible definitions based on what we thought a 4M opener looked like depending on seat and vul.

I typed the wrong thing and have edited the post to reflect what I meant to write. A 3NT opening as a solid major is also a possibility though and I am reasonably sure that at least some experts play it. As I recall, one of the benefits of the method is incredible accuracy in slam auctions (down to side jacks) at the cost of frequency (in comparison with the strong 4M opening option).

 

To add another possibility which does not look to have been mentioned: Magnusson - Ingimarsson are playing their 3NT opening as 6+m, 5+M (in addition to including this hand type in their 2♠ opening and including some 6+♦, 5+M hands in their 3♣ opening).
