Bergen Raise


This is a set of bids designed to show responder's hand strength and trump length in response to an opening bid of one of a major. (Something like 1-2 means raise in opener's major)

With exactly 3 trumps:

    6-9 HCPs = 1-2
    10-12 HCPs = 1-1N (artificial) then rebid 3
          (Bidding 1N and not rebidding 3 shows <10 points.)
    12-15 HCPs, balanced (with 3 trumps), stoppers in all side suits = 1-3N

With 4+ trumps:

    0-6 HCPs = 1-3
    7-9 HCPs = 1-3 (artificial) -- raise in opener's major
    10-12 HCPs = 1-3 (artificial) -- raise in opener's major
    12+ HCPs, hidden singleton/void = 1-3 other major
      Opener bids the next higher suit to ask responder
      to identify the suit with the singleton or void.

      Examples:

      After 1-3 (artificial: some singleton/void), 3 (artificial: asks what suit).

        Responder bids up the line:
          3N = Club shortness,
          4 = Diamond shortness,
          4 = Heart shortness.

      After 1-3 (artificial: some singleton/void), 3N (artificial: asks what suit).

        Responder bids up the line:
          4 = Club shortness,
          4 = Diamond shortness,
          4 = Spade shortness.
