Reading David Collier's excellent "Stayman v. Keri" blog entry (click on had me puzzled why nobody I've run into yet is playing Jeff Rubens's Inverted Stayman.

Inverted Stayman gets the partnership to 2M on 5M invite hands, but, in contrast to Keri, frequently has opener play the contract if that's the landing spot. Inverted Stayman works perfectly with the 5-4/4-5 major invite hands, unlike most other approaches.

Here's a simplified version of the ETM 06 Notrump structure (for the uber complex structure please click on using the terrific Inverted Stayman.


2C: Inverted Stayman, with all invites except 5-5+ in minors.
2D/H: Transfer, signoff or game force, can be just 4 card major if game force.
-- Responder's rebid of 2NT shows a 4 card major, or flat with 5, game force.
2S: Both minors, with a major suit singleton/void if less than a slam try.
-- Opener bids best minor if would decline a game invite, 2NT if would accept.
2NT: Transfer to Cs, signoff or game force.
3C: Transfer to Ds, signoff or game force.
3D: Game forcing Stayman.
3H/S: 4 in other major, singleton/void in bid major, game forcing.
4C: Transfer to Hs.
4D: Transfer to Ss.
Games: To play

2D: Any maximum, or minimum without a 4 or 5 card major.
-- non-jumps natural invites – opener will now show major if maximum
-- 3H/S: natural slam try with 4 card or longer major
2H/S: 4 or 5 cards in other major, fewer than 4 in this major, minimum.
-- Responder places contract
2NT: Both majors, minimum.
3C/D: Both majors, maximum, does not like bid minor (would pass invite in it).
3NT: Both majors, likes all suits.

    Hello Glen
    Thanks for all of this! It makes interesting reading... I have been through the etmnt06.pdf trying to understand the inverted stayman.

    The one thing (so far) that I'm not understanding is your use of the term constructive. Given that opener is limited by the 1NT range. (I'm assuming some 3 point wide range 10-12 12-14 15-17 etc.) What is the difference between constructive and invitational hands for responder.

    In the NT06 methods, constructive was meant in terms of being less than an invite, but close and therefore would have decent play for game opposite a good fit and a maximum. For example:

    S: x
    H: Kxxxx
    D: xx
    C: Kxxxx

    With constructive shapely hands launching via 2C, opener does not super accept the transfers to the major unless fit + shape + not soft values.
