| Puppet Stayman 
    - Used by responder with at least invitational values to discover whether opener's
Notrump bid may consist of a 5 card major suit.   In the sequence:  2N - 3C  
responder's 3C bid
behaves similar to the Stayman convention, but promising at least a 3 card major 
suit and at least game invitational values.  Using Puppet Stayman, responder 
can no longer use treatments like Garbage Stayman to show a bust hand short in 
Clubs since opener may jump directly to 3N with a good hand lacking major 
support.  Note: some extend Puppet Stayman to opener's 1 Notrump (1N - 2C) 
as well.   However others object to that treatment believing the often 
verbose bidding sequences reveal more information to defenders than the supposed 
benefit discovering a 5-3 major suit fit.  Using Puppet over opener's 1 
Notrump bid also permits defenders to Double artificial bids during the 
bidding, either for lead direction or possible sacrifice bids. Classic 
Puppet Stayman over 1 Notrump: Note: Several 
variations of Puppet Stayman are in use.    Method 1: Over Opener's 
1N
or 2N
 bid, some play responder's 2C or 3C should be used when 
holding a 3 card major to find a possible 8 card fit when opener 
holds a 5 card major. If opener does not bid the anticipated major, responder 
signs off in 3N as:  2N - 3C; 3D - 3N.
 Using this method, 
Responder bids 4D to show both 4 card majors:   2N - 3C; 3D - 4D.
 Method 2 - 
classic treatment: Unlike Method 1 
above, responder's 3N rebid promises  both 4 cards majors.  So 
in the sequence:   2N - 3C; 3D - 3N
 Opener may correct to a 4 level 
major suit game when holding 4 cards in either major. 
  
    | 1N - 2C;2H/S
   | If 1 Notrump opener has a 5 card major, opener may rebid the 
    major if responder makes a Notrump response.  With 3+ cards in opener's 
    5 card major suit, responder bids game, etc (may be slam-going).  
    Otherwise, responder makes appropriate Notrump bid. |  
    | 1N - 2C;2D
 | 
    If the 1 Notrump Opener has 4 cards in a major but no 5 card major, opener begins by bidding 
    2D |  
    | 1N - 2C;2N
 | If 1 Notrump opener does not 
    have a 5 or 4 card major, opener bids 2N. |  
    | 1N - 2C;2D - 2H/S
 | 
    If the 1 Notrump opener has 4 cards in a major, opener begins by bidding 
    2D. Next, responder bids 4 card major not held by the 
    responder (Smolen-like); this allows the stronger opener to become declarer.  
    Opener may now invite or force game in the other major with the 
    appropriate fit; otherwise, opener may make the appropriate Notrump 
    response. |  
    | 1N - 2C;2D - 2N
 See Note: | After the 1 Notrump opener 
    promises a 4 card major, the responder bids 2N to promise both 4 card 
    majors.  
     Note: alternative treatments 
    exist for partners that use 1N - 2N for other purposes (Minor Suit 
    Stayman or Four Way Stayman); those players must use the 1N - 2C; 2D - 2N 
    to show an invitational hand.  The alternative treatment may substitute
    3C or 3D in place of 2N to show 4-4 in both majors 
    (others may reserve minor suit rebids to initiate slam invites in the 
    respective minor suit). |  
    | 1N - 2C;2D - 3H/S
 | 
    When the opener shows a 4 card major and the responder has 4 cards in one 
    major and 5 cards in the other major, the responder bids the shorter 
    4 card major at the 3 level - thus allowing the stronger opener to become declarer. |  
    | 1N - 2C;2D - 3N
 | When responder does not have a 
    4 card major, responder signs off in 3N (implying opener does not have a 5 
    card major where responder does not have a 4 card major) |  Classic 
Puppet Stayman over 2 Notrump: Some prefer to play Puppet Stayman only after opener's 2 Notrump 
bid. After Responder 
bids 3C (showing game forcing values), Opener bids 3 in the major suit 
with a 5 card major, 3D with a 4 card major, otherwise 3N.  
  
    | 2N - 3C;3H/S
   | If 2 Notrump opener has a 5 card major, opener may rebid the 
    major if responder makes a Notrump response.  With 3+ cards in opener's 
    5 card major suit, responder bids game, etc (may be slam-going).  
    Otherwise, responder makes appropriate Notrump bid. |  
    | 2N - 3C;3D
 | 
    If the 2 Notrump opener has 4 cards in a major, opener begins by bidding 
    3D |  
    | 2N - 3C;3N
 | If 2 Notrump opener does not 
    have a 5 or 4 card major, opener bids 3N. |  
    | 2N - 3C;3D - 3H/S
 | 
    If the 2 Notrump opener has 4 cards in a major, opener begins by bidding 
    3D. Next, responder bids 4 card major not held by the 
    responder (Smolen-like); this allows the stronger opener to become declarer.  
    Opener may now bid game in the other major with the appropriate fit; 
    otherwise, opener bids 3N. |  
    | 2N - 3C;3D - 4C/D;
 | After the 2 Notrump opener's 
    3D promises a 4 card major, the responder may bid 4C/D to promise 
    both 4 card majors; some play 4C is slam invitational while 4D 
    only shows game-going values (slow shows, fast denies).  Playing this 
    treatment, opener can pre-accept bidding 4D to showing Hearts 
    or 4N to initiate slam ask in Spades.  Not 
    surprisingly, some creative folks reverse the meaning of 4C and 4D. |  Simplified 
Puppet Stayman over 1 Notrump: An alternative treatment is the simplified Puppet Stayman 
convention, credited to Marty Bergen; responder promises game-going values using this method. 
  
    | 1N - 3C; | Like its 
    big brother, the 3C Puppet Stayman asks opener to bid a 5 card major 
    or bid 3D holding a 4 card major. |  
    | 1N - 3C;3D
 | 
    If the 1 Notrump Opener has 4 cards in a major, Opener begins by bidding 
    3D |  
    | 1N - 3C;3N
 | If 1 Notrump opener does not 
    have a 5 or 4 card major, Opener bids 3N. |  
    | 1N - 3C;3D - 3H/S
 | 
    If the 1 Notrump opener has 4 cards in a major, opener begins by bidding 
    3D. Next, responder bids 4 card major not held by the 
    responder (Smolen-like); this allows the stronger opener to become declarer.  
    Opener may now bid game in the other major with the appropriate fit; 
    otherwise, opener bids 3N. |    |
