Please remember that EMBC Monday night bridge only allows Level 2 systems.
This item addresses the question "What does Level 2 mean'.
It has been updated with the Blue Book changes (1-9-2022).
One Level Opening Bids
A one-level opening bid in a suit must either show 11+ HCP, or show 8+ HCP and satisfy the Rule of 19. An opening 1NT must be non-forcing. It may show any agreed range with at least 10 HCP, with no singleton or void and no 7-card suit. Within those constraints, any common English system may be played e.g.:
• Natural one-level openings (such as Acol), including the possibility of a three-card minor suit opening on some balanced hands
• Five-card majors with better minor or a short club suit
• A strong club, possibly with a nebulous 1D opening (e.g. Precision, Blue Club, Nottingham Club). The 1C opening must, by agreement, satisfy
(a) any hand of at least 16 HCP
(b) any hand of as few as 13 HCP in any two suits totalling 10+ cards
All standard responses are permitted, but (apart from negative responses to a Strong 1C opening, or a catch-all 1NT response) artificial weak bids in response to a one-level suit opening are not allowed. This means transfer responses to a short club opening are not permitted.
Two Level Opening Bids
Any opening that shows 4+ cards in the suit opened is allowed (e.g. Acol Twos, Lucas or Weak Twos, a Precision 2C opening), as is any meaning or meanings showing a hand conforming to 16+ HCP or 13+ HCP in any two suits totalling 10+ cards (e.g. Benjamin 2C and 2D openings).
A two-level opening showing a three-suited (4441, 5431 or 5440) opening bid including length (three or more cards) in the suit opened is also allowed. Alternatively, two of a suit may show a three-suited opening bid short in the suit opened (such as the Precision 2D opening).
‘Multi’ style openings are not allowed. Neither is a 2NT opening bid showing the minors.
