Editing Stayman convention (section)

==Non promissory game forcing Stayman==

This allows responder to find exact shape of 1NT opener. Developed for use with weak 1 NT opening. Relay bids over opener's rebids of 2{{Diams}}, 2{{Hearts}}, 2{{Spades}}, 2NT, 3{{Clubs}}  allow shape to be defined further if attempting to find 5-3 major fits. Advantages are responder's shape, which may be any distribution, is undisclosed, and responder is able to locate suit shortage holdings not suitable for no trumps.

Responder's rebid of 3NT denies 4 card major); 2NT invitational hand with both 4 card majors (opener's rebids: no bid no 4 card major 12-13 HCP,  3{{Clubs}} 4 hearts 12-13 HCP, 3{{Diams}} 4 spades 12-13 HCP, 3{{Hearts}} 4 hearts 14 HCP, 3{{Spades}} 4 spades 14 HCP, 3NT 14 HCP no 4 card major).
