Multi 2 / NF Multi 2

Although it has all the properties of a brown sticker convention, in many countries and in the WBF regulations this bid is an exception. It has earned this by popularity, not because it is so easy to defend. The options that are included in the Multi vary, although the following 5-way treatment is popular in Holland:
  • Weak Two in /
  • Strong NT
  • SemiForcing in /

    Further Bidding
    2 (over 2): Negative or invite for only See below
    2 Invite for only, or weak 4+ See below
    2NT Invite or better, strong relay See below
    3/ Natural, constructive, not forcing
    3/ Pass or correct
    4 I want to play in your major Opener bids suit below major
    4 Bid your major


    There is also a non-forcing Multi. An opening bid of 2 shows a weak two in either major! Responses are as above, only after 2 (pass) we have to guess what to do. This version is Brown Sticker, except in Germany where a translation error resulted in this approach being legal.

    The responses 2 and 2

    Over 2, opener now shows his hand naturally:
  • Pass: Weak Two in
  • 2: Weak Two in
  • 2NT: Strong NT
  • 3: Semiforcing
  • 3: Semiforcing

    • With 2, partner has given a positive response for only.
    Partner may also have a weak hand with 4 or more , in which case there are two reasons for bidding 2:

  • If partner has a strong balanced hand, partner should play a -contract if we have a fit.
  • If partner has a weak two in , he may preempt opponents ignorant of your weakness.

    Opener passes with a weak two in , and may accept the invite with a weak two in :

  • 3: Minimum weak two in
  • 4: Maximum weak two in

    The relay 2NT

    Opener now shows his suits and strength in the following way:

    2 - 2NT - ?
    3 Minimum weak two in 3 is to play, 3 slam-going with fit
    3 Minimum weak two in 3 is to play, 3 slam-going with fit
    3 Maximum weak two in (!) Any non-game bid is slam-going
    3 Maximum weak two in (!) Any non-game bid is slam-going
    3NT AKQxxx in a major

    Bidding after interference

    If opponents double or Multi, pass suggests 5+ and willingness to play there. Redouble shows tolerance and a strong hand that is eager to double for penalty. The rest stays the same.

    If they overcall 2 or 2, double shows 3-card support for the other major. If opponents have stumbled into opener's long major he will pass the double.

    After higher interference double is for penalty, and a major is pass or correct.

    Interference after 2 NF Multi:

    2 (dbl) pass = pass or correct, rdbl = pass even if you have
