Openings
| 1♣ | 11–23, 2+♣ |
| 1♦ | 11–23, 4+♦ |
| 1♥♠ | 11–20, 5+# |
| 1NT | 15–17, 2–5♠, 2–5♥, 2–6♦, 2–6♣ |
| 2♣! | 21+, (5+♠♥ or 6+♦♣ or 24+) |
| 2NT | 21–23, 2–4♠, 2–4♥, 2–6♦, 2–6♣ |
Prefer 1♦ to 1♣ when holding (xx)45 because there is hardly any way for a 1♣ opener to show 4+♦ however strong. This canapé deviates from standard natural bidding.
The ACBL Basic Chart forbids a natural 2NT from bearing a void or a singleton < Q. Thus, 1♣♦ have to handle strong hands which are disqualified from 2NT and lack a rebid after the 2♣ opening.
Basic+ agreements, optional
The agreements in this section requires the ACBL Basic+ Chart.
Off-shape 2NT
Basic+ allows all very strong 2-level openings.
| 1♣ | 11–20, 2+♣ |
| 1♦ | 11–20, 4+♦ |
| 2NT | 21–23, 0–4♠, 0–4♥, 0–6♦, 0–6♣ |
Preemptive 2NT
Basic+ allows 2NT to show 5+ 4+ minors. The unusual 2NT is therefore permitted.
| 1♣ | 11–20, 2+♣ |
| 1♦ | 11–20, 4+♦ |
| 2♣! | 21+ |
| 2NT | 4–10, 5+♦, 5+♣ |
