Responses to a Simple Overcall

New suit:

    Check the box that best describes your agreements if partner bids a new suit in response to your simple overcall.

    Forcing:

    Check if new suit is forcing in response to an overcall. If sometimes forcing, sometimes not (other than by passed hand), do not check the box but be ready to answer questions.

    Check if the response is constructive but not forcing.

    Check this box if the response is non-forcing and also is not constructive. For example, check this box if you are likely to bid 2 with KT9xxx on an auction of
    1 - 1 - Pass - You.

Jump Raise:

    Check whichever box describes your agreement.

    Forcing:

    Check this box if a jump raise in the overcalled suit is forcing to game.

    Inv.:

    Check this box if a jump raise in the overcalled suit is invitational to game.

    Weak:

    Check this box if a jump raise in the overcalled suit is preemptive, and just shows length in your suit. Remeber that this treatment requires an alert.

Other:

    On the blank line at the bottom of the Simple Overcall section, list any other conventions/treatments that you play in response to a simple overcall.

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