Tartan Two-Bids

These two-bids were conceived by Mr. Hugh Kelsey and Mr. Tom Culbertson. The essence of the concept is: 2 Hearts and 2 Diamonds are Multi openings, which become clear after a series of relay responses. See the following chart for the general partnership understanding, which has been varied over the years:

Opener Responder Meaning
2H The meaning is yet to be determined
2S Relay or cheapest bid
2NT Shows 21-22 high card points and balanced holding
3C Shows normally 5-5 in Hearts and Clubs
3H Shows normally 5-5 in Hearts and Diamonds
3H This rebid by the opener and all higher rebids are considered Acol Two bids showing Hearts (16+HCP)
2S The meaning is yet to be determined
2NT Relay or cheapest bid
3C Shows Spades and Clubs, 5-5 distribution, and 6-10 high card points
3D Shows Spades and Diamonds, 5-5 distribution, and 6-10 high card points
3H Shows Spades and Hearts, 5-5 distribution, and 6-10 high card points
3S This rebid by the opener and all higher rebids are considered Acol Two bids (16+HCP)

Some partnerships have the understanding that an opening also of 2 Hearts is understood to show also a 5-card Heart suit and an unnamed (not unspecified) 5-card Minor suit, an unbalanced holding, and only 6 to 10 high card points as with the 2 Spades opening. This is by partnership agreement.

It is also possible that a 2 Diamonds opening could be Roman Two Diamonds showing a strong three-suiter, but this is by partnership agreement.
