- What?: The 2D response to 1NT is "Stayman for hearts" and asks if opener has four+ hearts or not.
- For who?: Mainly for people playing that the transfer to hearts can be a four card suit if invitational.
- Hand types?: Responder can have a normal Jacoby transfer hand (5+ hearts, any strength), or invitational values with 4 hearts, or an invitational hand without a major.
- Why?: Balanced invites without a major can be excluded from 2S/2NT.
1NT-2D;
2H = Not four hearts.
...2S = INV with 5 hearts (additional meanings possible, if desired).
...2NT = INV with less than 5 hearts.
...3C+ = 5+ hearts.
2S = Four+ hearts, accepts an invite with four hearts.
...2NT = Re-invite, less than four hearts.
...3D = Re-transfer. Could be weak.
...3NT = To play.
...Others = GF, sets hearts.
2NT = Four+ hearts, not accepting an invite with four hearts.
...Pass = Had the balanced invite.
...3D = Re-transfer.
...Others = GF sets hearts.
Unfortunately there are several cons to the method:
- If opponents interfere opener can not know if responder has hearts or not

- Gets us the the three level as soon as there is a 5-4 heart fit. Some people always super-accept with four though. A solution could be to deny four hearts if holding 3-4-3-3 (but then risks missing 4-4 heart fit).
- Reveals if opener has four+ hearts or not, even if responder isn't interested. Better than playing four way transfers though, where 2C Stayman has to be bid with invitational hands and no major.
Again, the upside would be to not have the "invitational, no major" elsewhere, which can be useful.
