The form of 3C Puppet Stayman used over 1NT opening bids described by Justin
Lall (and congrats to him for winning the Nail Life Master Pairs in Seattle
yesterday) at
http://justinlall.com/2011/09/07/puppet-stayman-after-a-1n-opener/
which he credits learning from Joe Grue does a great job of hiding
information from the defenders by not giving away needless information about
the 1NT opener's hand when responder has a game forcing hand with minimal
slam interest.
The major features of this form of 3C Puppet Stayman over 1NT are:
1. Opener can only bid 3D (denying a 5-card major) or 3 of a major showing
a 5-card suit. 3NT is NOT an allowed response.
2. Responder uses 3C Puppet Stayman with ONE 4-card major. Responder uses
regular 2C Stayman with TWO 4-card majors.
One question asked about this method is how you find your 8-card fits when
responder is 3-5 (3 spades, 5 hearts) or 5-3 (5 spades, 3 hearts).
I have invented a solution to this problem thanks to the use of this form of
3C Puppet Stayman that Justin has described. An additional benefit is that
the 1NT opening bidder will be declarer in all cases.
The two auctions 1NT-2C-2H-3NT and 1NT-2C-2S-3NT cannot theoretically occur
because responder would have bid 3C Puppet Stayman with a single 4-card
major. We can use these two auctions artificially to show 3-card support
for opener's major with 5 cards in the other major.
But what if opener bids 2D denying a major? Then you fake a Smolen bid,
jumping to 3 of your 3-card major, and in the process showing five cards in
the other major, which is the only suit at that point in which you can have
an 8-card fit.
In summary,
1. With 3-5 in the majors, use regular 2C Stayman and here are your three
auctions:
(a) 1NT-2C-2D-3S (shows five hearts via fake Smolen)
(b) 1NT-2C-2H-4H
(c) 1NT-2C-2S-3NT (choice of games with 3-5 majors)
2. With 5-3 in the majors, you use regular 2C Stayman and here are your
three auctions:
(a) 1NT-2C-2D-3H (shows five spades via fake Smolen)
(b) 1NT-2C-2H-3NT (choice of games with 5-3 majors)
(c) 1NT-2C-2S-4S
Here is a table of the responses I have constructed for several major suit
distributions held by responder when he holds a game forcing hand without
slam interest after partner opens 1NT:
One or two 3-card majors
3C, then raise opener's 5-card major to game or over 3D bid 3NT
One 4-card major (possibly with a 3-card major)
3C, then over 3D bid the 4-card major you do NOT hold
3-5 or 5-3 majors
2C - 2D - 3 of your 3-card major (faking Smolen to show your 5-card
major)
2C - 2 of your 3-card major - 3NT (artificial) showing the 3-5 or 5-3
majors
2C - 2 of your 5-card major - 4 of the major
4-4 majors
2C, then raise opener's major to game or bid 3NT
4-5 or 5-4 majors
2C, then Smolen over 2D or raise opener's major to game
4-6 or 6-4 majors
2C Stayman, then raise opener's major to game or over 2D use delayed
Texas; or use Texas directly and give up on the possible fit in the other
major
5-5 majors
Transfer to 2S and bid 3H; OR
Use 3D, 3H, or 3S to show a 5-5 majors game force
You can also show hands with some slam interest that are 5332 type shape
with a long minor and also 4432 type shapes with one 4-card major and one
4-card minor by first starting with 3C Puppet Stayman. You can learn more
about those at the end of Justin's description of the convention.
