Bergen Over 2NT

One-Suited Hand:
    Double = one-suited hand. Partner bids 3.

Two-Suited Hands (at least 6-5):

    3 = Clubs and any other suit
    3 = Diamonds and Hearts/Spades
    3 = Hearts and Spades

    Partner passes with a fit or bids the next higher suit to ask overcaller to show his 2nd suit. If the next higher suit is overcaller's second suit, he will pass; otherwise, he bids the 2nd suit.

    If the overcall is doubled for penalty, a redouble by responder is S.O.S, asking overcaller to bid his second suit.
