~2/1: What does 1D-2C Mean?

1. A game-forcing 2/1 auction that either does or does not deny a 4-card major, depending on partnership agreement. If the partnership holds an 8-card fit in a major, it can be found in subsequent bidding.

2. A game invitation denying a 4-card major and initiating a show of stoppers in the majors (and point counts) in a 3NT try. The fallback contract may be in either minor and at any level (3 or above).

3. A game invitation without denying a 4-card major.

The choice of options depends on your partnership’s bidding philosophy. Duplicate scoring methods place an advantage in finding a fit in a major suit or in NT. For those reasons, it is rarely correct as responder to bypass a 4-card major. There are also strong reasons for playing 1D-2C as an invitational bid with emphasis on exploring for a NT game. For these reasons, we recommend option 2.

    Joan and I play 2/1 over a 1D opener and use the first definition above. We also play a short club opener and therefore a 1D guarantees 4 cards. we check the blue 0-2 for clubs on our convention card and the 4 for D and then alert the club opener. In 2C/1D we also play a short C response and alert it, “could be short.” Is this a legitimate approach for a 2C response with 2cards in clubs? Less than 2 cards?
