Extract from the White Book: Section 172 Level 5 Permitted Conventions [C3+L3] 171
172.3 Brown Sticker Conventions & Treatments |
||
| Brown Sticker Conventions and Treatments may not be played, unless they are permitted at EBU Level 3. The following conventions or treatments are categorised as 'Brown Sticker': | ||
| (a) | Any opening bid of two clubs through three spades that: | |
| (1) | could be weak (may by agreement be made with values below average strength) | |
| AND | ||
| (2) | does not promise at least four cards in a known suit. | |
| EXCEPTIONS: | ||
| (1) | The bid always shows at least four cards in a known suit if it is weak. If the bid does not show a known four card suit it must show a hand a king or more over average strength. ( Explanation: Where all the weak meanings show at least four cards in one known suit, and the strong meanings show a hand with a king or more above average strength, it is not a Brown Sticker Convention.) |
|
| (2) | A two level opening bid in a minor showing a weak two in either major, whether with or without the option of strong hand types, as described in the WBF Conventions Booklet, is not a Brown Sticker Convention. | |
| (3) | AKQxxx(x) in a single suit is not a hand which is below average strength | |
| (b) | An overcall of a natural opening bid of one of a suit that does not promise at least four cards in a known suit. | |
| EXCEPTIONS: | ||
| (1) | A natural overcall in no trumps | |
| (2) | Any cue bid suit that shows a strong hand. | |
| (3) | A jump cue bid in opponent's known suit that asks partner to bid 3NT with a stopper in that suit | |
| (c) | Any 'weak' two-suited bids at the two or three level that may by agreement be made with three cards or fewer in one of the suits. | |
| (d) | Psychic bids protected by system or required by system. | |
| (e) | None of the foregoing restrictions pertain to conventional defences against strong, artificial opening bids or defences against 'Brown Sticker' or HUM conventions. | |
