| Response | Meaning |
|---|---|
| A simple raise | Shows 3 or 4-card support and approximately 6-13 points (insufficient values for a game contract). It is preemptive and completely non-forcing. |
| A jump raise | Usually shows a weak, preemptive hand (with at least 4-card support). It is also common to make a 4 / jump raise with 5-card support regardless of strength. However, a major suit jump raise may also be made by a strong hand that believes the game contract will succeed. |
| A new suit | Natural and non-forcing, typically showing a 6-card suit and denying support for partner’s suit. |
| 2NT | Ogust |
| A cuebid of an opposing suit | Usually played as a forcing raise with interest in game. With a minimum hand, overcaller can rebid his suit at the cheapest level. With a strong hand, overcaller can bid game or a side suit ace or king. |
