Intermediate Jump Overcalls
Intermediate jump overcalls are more constructive than weak jump overcalls. A jump overcall at the 2-level shows a 6-card suit and 11-15 points. A jump overcall at the 3-level shows a 7-card suit and 11-15 points. Responder's available bids are:
| 2NT | In response to a 2-level jump overcall, 2NT is 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).
