Classification of the bidding systems in contract bridge
March 25, 2009Written by nicolae
English
Natural systems in general have the following features:
Level-1 suit bids denote at least 4 or 5 cards in a major suit, and 3 or 4 cards in a minor suit, with strength of about (11)12-20(22) high card points. The suit bid is generally the longest. The former criterion inflicts further classification into four-card major and five-card major systems.
Bid of 1NT always presents a balanced hand in a narrow high card points range. The common ranges are 15-17 or 16-18 HCP ("strong notrump") and 12-14 ("weak notrump").
Bid of 2♣ typically presents a very strong hand (23 HCP up).
