Major Suit Inquiry

Allows 2NT Opener to have a 5 card major. Also allows Responder to find all fits with 5-4 in the majors (contra Puppet). We can also show one 5+ minor suit, either with or without a 4 card major.

Responder bids 3♣ with:

One or two 3 card majors.
One or two 4 card majors.
4-3 in the majors
5-4 in the majors
Any of the above with a minor suit
(Optional) a minor one-suiter

With one or two 5 card majors, use Jacoby transfers. Responder's 5-3 in the majors cannot be handled; choose the lesser evil of a Jacoby transfer (showing 5-2) or 3♣ (showing 4-3).
