| No-trumps | to play |
| Any raise | to play and possibly pre-emptive, unless Minorwood |
| Cue bid of the opposition's last-bid denomination | Unassuming Cue Bid, promising a solid raise, but only if opponent's bid can be expected normally to contain 3+ cards and/or has been supported by their partner. This overrides the "probe for 3NT" meaning, which doesn't apply as a direct response to partner's overcall. |
| Cue bid of any other denomination | natural, showing a good suit there despite the fact that the opposition had previously bid it. |
| Jump cue bid | splinter, again not a "probe for 3NT". |
| New suit | forcing if the next hand passed |
| Jump shift | fit-jump, forcing. Shows trump support with a side-suit, at least 5-4, ostensibly not strong enough for game but might also be a stronger hand that's interested in a higher contract and is planning to keep bidding. |
| 1NT | Natural and invitational, expected to be a useful intermediate hand or equivalent. Might also be stronger and downgrading for shortage in partner's suit. |
| 2NT | Natural and invitational, showing values appropriate for what's expected from partner's bid at the position and vulnerability. |
| Jump to 2NT | Natural and invitational, showing a solid opening hand with further valuable features, e.g. either a useful holding in partner's suit or additional high-card strength. |
| 2NT over a weak jump overcall | Ogust |
| Unnecessary jump shift up to Splinter Level | Splinter, agreeing partner's trump suit and showing a small singleton or void. Splinters are normally game-forcing, but if two of them were available then the lower is merely invitational, e.g. 1C 1S 3D/4D are both splinters, since 1C 1S 2D would have been a reverse. |
| 4NT | RKC Blackwood |
| Jump shift to Blackwood Level | Exclusion Blackwood |
| Jump shift to Grand-Hunting Level | Complete two-suiter. If the partnership had previously bid more than one suit and so there's ambiguity about which suits are being promised, then the other one is the first-bid suit of the player who just jumped. |
