PUPPET STAYMAN

After partner opens 2NT, 3 ♣ begins an inquiry regarding possible Major suit fits. Responses are as follows:
3♦ = I do not have a 5 card major, but I do have 4 cards in at least one of the majors.
3♥ = I have a 5 card Heart suit.
3♠ = I have a 5 card Spade suit.
3NT = I don’t have any Major longer than 3.
Once responder learns of the existence of an unknown 4 card Major (via 3♦), he bids as follows:

3♥ = I have 4 Spades.
3♠ = I have 4 Hearts.
3NT = I am not interested in 4 card majors – this is "to play". In this case, Partner was testing to see if Opener had a 5 card major and would have played in a 5-3 fit.

Other holdings by responder after the 2NT opening bid.

Responder with a 5 card major will show it via a transfer sequence.

3♦ /♥ ..........asking for transfer to ♥/♠

Responder with 5 Spades and 4 Hearts

Bids 3♠ over 2NT. This specifically shows a holding of 5 Spades and 4 Hearts

Responder with 5 Spades and 5 hearts

bids 3♥ over 2NT, and then bids 4 ♥ over the forced 3♠

Responder with 5 Hearts and 4 Spades

bids 3♦ asking for transfer to 3 ♥, and then bids 3 ♠ over the forced 3♥ response.

These last 2 sequences shows the difference with holdings of 5/4 and 5/5 in the majors, and avoids the danger of playing 4♥ on a 4/2 fit
