Weak Two opening bids.
Weak Twos are opening bids that show 5-10HCP and six cards in the bid suit.
  • By opening 2 you make it harder for the opps to find a fit in one of the other suits.It acts as a preemptive bid.
  • For a weak 2 to be most effective, and less risky, it is important that the opener.
      has concentrated strength in his six-card suit .
      does not have a side four-card major,.
      adapts his strength to the vulnerabilities.

    Responses to a 'weak Two'
    there are 4 types of rebid after a 'weak two':
       A simple raise shows 3 or 4-card support and approximately 6-13 points (insufficient values for a game contract). It is preemptive and completely non-forcing.
       A jump raise Usually shows a weak, preemptive hand (with 4-card support) or 5 cards and almost nothing. But it may also be made by a strong hand that believes game will make.
       A new suit
      Natural and round forcing, it shows at least a 5-card suit and denies support for partner's suit.... However, some pairs prefer to play a new suit as natural and non forcing..

       2NT
      Strong, artificial forcing bid. Opener is asked to show a feature in a side suit, i.e. an ace or king, by bidding that suit at the three level. The objective being to assess if a game is makeable and to choose a suit or NT contract.
