  • Inverted Minors
    Inverted Minors Theory The Inverted Minor treatment is a virtually integral part of the Two-Over-One Game Force system, but it can be employed in many systems. The underlying principle, as in 2/1, is that the bidding should be escalated quickly with weaker, pre-emptive hands, and that the bidding be kept low on strong hands in order to properly investigate the proper game or slam contract. General Treatment A jump raise of partner's opening 1-level minor suit opening (suit of 3+ cards) is a pre-emptive bid and promises 5+ card support and a limited hand (less than 9 support points). It strongly discourages further exploration of game contracts (except by a very strong opener). A single raise of partner's opening 1-level minor suit opening is a strong bid; it is forcing to (at least) three of that minor and is strongly suggestive of a game in either NoTrump or in the suit. It is an unlimited bid. If the partnership agrees, a jump shift into the other minor suit may be used as a limit raise of the suit opened ("criss-cross"). A sequence of 1♣ - 2♦, or a sequence of 1♦ - 3♣ would then promise 5+ card support for the suit opened and 9-12 support points. It says nothing about the suit bid. In this case, the single raise is reserved for hands that contain a full opening hand. This permits a better distinction of the ultimate contract. Inverted minor raises are not used when the opponents overcall (or double) the opening bid.
