Intermediate Jump Overcalls

Home > Bidding > Intermediate Jump Overcalls

Intermediate jump overcalls show a 6-card suit and 11-15 points at the two-level of bidding. Obviously they are intended to be more contructive than weak jump overcalls. Responder's available bids are:

2NT Artificial and forcing (see below).

New suit Natural, nonforcing. Usually denies 2+ cards in support.

Single raise Preemptive. Partner is expected to pass.

Double raise Natural, signoff. May be strong or preemptive.

The responses to the artificial 2NT query depend on a partnership's agreements. The Ogust set of conventional responses works well; if not playing Ogust, however, a three-level new suit can show a control (ace or king).
