NO TRUMP BIDDING
a. Strength ‑ High cards points only (never distribution) are counted. The presence of a
5-card suit is worth one point, and the presence of tens can also be taken into
account. The system is based upon 26 HCP's = Game, 34 HCP's = Small
Slam, and 37 HCP's = Grand Slam.
b. Distribution ‑ Only balanced hands; i.e., no voids, no singletons, and not more than one
doubleton, qualify. (Examples: 4‑3‑3‑3, 4‑4‑3‑2, 5‑3‑3‑2)
(1) The 5‑card suit is rarely a Major suit.
(2) Distributional exception: (5‑4‑2‑2) Where the two doubletons are Major suits
headed by an Ace or a King (Example: KX AX KJXX AQXXX).
c. Location Of Strength ‑ The concentration of honors, presence of any tenaces (AQ, KJ, etc.),
or the holding of a worthless doubleton are rarely considered.
