Main objective is not to reveal the shape of the concealed hand (opener) on typical auctions; hence opener must rebid 2
with or without a 4-card major, then responder (usually dummy) describes. Showing a 5-card major over Stayman is optional; i.e., opener may suppress with notrump-oriented values. Responder’s rebids are artificial and specialized.
Details
The 2
response to 1 NT is a modified version of “puppet” Stayman. Responder must have at least game interest unless he is able to pass opener’s rebid of 2, 2
or 2
.

After interference:
All doubles or redoubles by either player are for penalty.
If responder’s L-H-O doubles 2 or bids 2, the structure is unchanged (assuming no further enemy bid). Opener should make his normal rebid or pass, double or redouble. If responder rebids 2 it is to play (he would have passed 2 ).
If either opponent bids 2 or higher (after the Stayman 2 bid), the structure is off and the bidding reverts to a natural style. If opener cannot make his normal rebid, he should pass or double. If responder bids a major suit, he shows 4 cards in that suit (3 could be both majors after a 3 or 3 overcall); this is invitational at 2 or forcing at the 3 level. Opener may raise, return to notrump, or show the other major if appropriate.

After a 2 NT opening:
The use of puppet Stayman after 2 NT is almost identical to after 1 NT, although any bid that commits the partnership past 3 NT with no assured major fit promises slam interest.
