Opening bid of 1 of a suit, followed by raises in the same suit
When supporting partner’s suit with an 8 card fit, add 1 point for a doubleton, 3 for a singleton, 5 for a void.
SINGLE RAISE (e.g. 1H to 2H)
A single raise by Responder shows 6-9 points with 4 card support. In the Minor suits it generally denies having a 4 card major.
| Opener's rebids | Responder's rebids | |
|---|---|---|
| Pass if minimum | ||
| 3 of same suit | Pass (minimum), Bid game (maximum) | |
| 4 of same suit | Pass or raise to 5C, 5D | |
| 2NT 17 - 18 & only 4 card support | Pass, 3NT, 3 or 4 of suit | |
| 3NT 19 - 20 & only 4 card support | Pass or 4 of suit | |
| New suit - a "trial bid" requesting help in that suit | ||
DOUBLE RAISE (e.g. 1H to 3H)
A double raise by Responder shows 7-10pts with 5 card support & shape, or 11-12pts with 4 card support.
Opener will Pass if minimum, or bid game in suit or NT
TRIPLE RAISE (e.g. 1H to 4H)
A triple raise by Responder shows exceptional trump support & shape, low honour count (say 5-10 HCP).
Opener will Pass, or with a strong hand investigate a slam with Blackwood (4NT - see Table 13).
Note: With 16+ points, Responder should consider a jump shift in a different suit - see Table 7.
