3NT

Gambling 3NT. Opener has a completely solid 7-card minor with nothing outside.

Responses

If 3NT seems unlikely, responder can remove to 4C, for possible correction.

Partnerships may also adopt 4D as a shape enquiry. opener will rebid 4NT with no singleton or void, a major to show a singleton or void in that suit, or game in his minor to show a singleton or void in the other minor.
