MINOR OPENINGS

Expected Min. Length

    Mark the expected minimum length for one-level minor openings. It is good to make helpful notes if you have specific understandings, such as:

    • 1 is opened with 4-4-3-2 distribution (exactly).
    • If your 1 opening is part of a big club system and promises 0+ or 1+ diamonds.

    If you open 1 with 3-3 in the minors, opening 1 with a three-card suit only if the distribution is 4-4-3-2 exactly, check the 3 box but write an arrow pointing to 4 for the 1 opening, noting that 1 normally shows 4+ diamonds.

    If you play that 1 or 1 shows 5+ in the suit, check the other box and write "5+" or whatever applies adjacent to the box.

 

    RESPONSES to One of a Minor

Double Raise:

    Check the box that applies:

Force

    If playing strong raises

Inv.

    If playing invitational (limit) raises

Weak

    If playing preemptive jump raises

After Overcall:

    List here what a double raise is after an intervening overcall. Fill this in if a double raise is different after a competitive bid by an opponent. See Over Opp's T/O Double if the intervening call is a double.

Forcing Raise:

    If a forcing raise is something other than a double raise, check the appropriate box:

J/S in the other minor (Jump Shift)

    Check this box if you use Jump/Shift in the other minor
    (1-2 or 1-3) to show strong support for opener's minor. If you have an agreement about the minimum length that this bid would show, write that on the same line, next to the box.

Single Raise

    Check this box if playing inverted minor raises so that 1-2 or
    1-2 shows a strong raise of opener's minor. Again, indicate any agreements as to minimum expected length.

Other:

    On this line write any other special agreements you have for showing support for opener's minor opening.

Frequently bypass 4+

    If your style is to bid suits up the line, do not check this box. If you may systemically bypass a diamond suit to bid a four-card major, check the box and be prepared to answer questions about your specific tendencies in this area, if you have any agreement.
    If 1-1 is something special, write in the line to the right of Other at the bottom of this section.

1NT/1:

    Put in the applicable HCP range.

2NT:

Forcing

    Check this box if a 2NT response to one of a minor is natural and game-forcing

Inv.

    Check this box if 2NT is invitational and also fill in the point range.

3NT:

    For a natural 3NT response, indicate the point range.

Other:

    Use this line for any other conventions or treatments that you use in response to a one-of-a-minor opening bid.

The above is the official ACBL convention card guidelines as of Sep 2000.
