Minor Suit Stayman - The Minor Suit Stayman conventions has several
variations, usually complementing treatments to handle minor suit transfers,
minor slam try, etc. Two sequences typically initiate Minor Suit
Stayman, responder's Spade bid in reply to partner's opening 1 Notrump:
1N - 2S;
2N - 3S;
Note: 1N - (overcall) - ? Minor Suit Stayman is "off"
when opponent overcalls
The responder generally uses these sequences to show length in the
minor suits - 4 or 5 depending on partnership agreements and
responder hand type; the responder
always denies a 4 card major. The Minor Suit Stayman is useful
to describe four types of responder hands:
1.
Minor suit signoff to play (Club-Diamond bust, with 5-5 or more in minors)
2. Transfer to 3C with a Club bust (in contrast to Four
Suit Transfers)
3.
Long Diamond suit to play at 3 level (Diamond bust)
4.
Slam interest in the minors (some play 4-5/5-4 in minors, other prefer 5-5),
possibly with a singleton or void in a major suit
|
1.
Minor suit signoff to play (Club-Diamond bust, with 5-5 or more in minors) |
|
1N - 2S;
2N no support
3C Club support
3D Diamond w/o
Club support
1N - 2S;
2N - 3C;
P/3D |
After responder bids 2S,
opener bids the lowest 4 card minor or bids 2N lacking support.
Notice the similarity to regular Stayman; with the regular Stayman, opener makes a neutral bid (2D
with Stayman).
In the case of Minor Suit
Stayman, opener's neutral bid is again the lowest step, 2N after
responder's 2S asking bid to deny 4 card support.
Responder then rebids 3C,
permitting opener to Pass or correct to 3D with better
Diamond support. |
|
2. Transfer to 3C
with a Club bust |
|
1N - 2N;
3C |
Responder's 2N bid
forces opener to bid 3C; responder Passes indicating a Club
bust |
|
3.
Long Diamond suit to play at 3 level (Diamond bust) |
|
1N - 2S;
any- 3D |
Responder's 3D rebid is always a sign off showing a Diamond
bust, opener must Pass. Thus, if opener rebids 3D,
responder simpy Passes. |
|
4.
Slam interest in the minors (some play 4-5/5-4 in minors, other prefer 5-5),
possibly with a singleton or void in a major suit |
|
1N - 2S;
3C/D - ?
3H/S |
When responder rebids above
3D, responder implies a fit with opener's rebid suit and
responder's rebid suit shows a singleton or void with strong slam
interest. Opener may attempt to signoff in 3N or
initiate slam Ace-asking bids with extras. |
|
1N - 2S;
2N - ? |
If opener denies minor card
support, responder may use other tools to explore slam such as Gerber
Ace-asking bids or Quantitative Notrump bids. |
