These original opening bids have gained enormous popularity of the followers of the Precision bidding system, which was devised by Mr. Chung Ching Wei (aka Charles Wei or C.C. Wei), of Taiwan, during the 1960s and early 1970s, and which proved quite successful as employed by the team members of the Taiwan (Republic of China) teams Bermuda Bowls during the years 1969 and 1970. Mr. Chung Ching Wei was born July 12, 1914 and died on February 20, 1987. Mr. Chung Ching Wei was born in Sheng County, Zhejiang Province, China.

Note: In the year 1965 Mr. Chung Ching Wei devised, developed, and originated the China Bidding System, which eventually became designated as the Precision Club Bidding System. It was after the initial success of this bidding system, placing Runner-Up in the Bermuda Bowl in the year 1969, that the famous Italian Blue Team adopted the principles and features of this bidding system. The employment thereof maintained their dominance and supremacy at the international tournaments for a period of approximately twenty years.

     

Note: Taiwan followed the Italy in winning Second Place at the Bermuda Bowl tournament in the year 1969. Team members included Frank Huang, Patric Huang, C. S. Shen, K. W. Shen, Kovit Suchartkul, M. F. Tai, Chung Ching Wei (npc).

Note: Taiwan followed the United States winning Second Place at the Bermuda Bowl tournament in the year 1970. Team members included Conrad Cheng, Elmer Hsiao, Patric Huang, Harry Lin, M.F. Tai, David Mao (npc).

His wife, Katherine Wei, with the assistance of several bridge experts such as Mr. Ron Anderson and Mr. Terence Reese were successful in promoting the Precision Club bidding system. The approach became a very popular bidding system in the United States and the concept soon became varied, modified, altered, and extended to the extent that the only thing all agreements still had in common was the 1 Club opening bid. Such variations were often devised to meet specific scoring formats such as match point scoring.

Note: The team members of the famous Blue Team of Italy, long time favorite at international tournaments adopted the Precision Club bidding system or rather the fundamental concept of the approach. Modifications were made for adjustments, particularly by Mr. Benito Garozzo and Mr. Giorgio Belladonna, which then became known and designated as Super Precision.

The book illustrated below was authored by Mr. Chung Ching Wei and edited by Mr. Terence Reese. ISBN-10: 0910791384 / ISBV-13: 978-0910791380.

     
     

Opening Bids Only

Bid Strength Meaning
1 : 16 plus high card points Shows any shape.
    Note: This bid is strong, artificial and forcing for one round. This bid promises virtually any distribution. On very distributional hands, with a 7-card suit, for example, or a 6-5 two suiter, the point count can be shaded by one point or, rarely, two points.
1 : 11-15 high card points Promises 3 plus Diamonds.
    Note: A natural opening bid, but originally promisingat least a 3-card Diamond suit. As the concept evolved and as certain 11-12 point hands were awkward to bid, the suit length became lowered to a 2- card Diamond requirement.
1 : 11-15 high card points Promises a 5-card plus Heart suit.
1 : 11-15 high card points Promises a 5-card plus Spade suit.
1 NT: 13-15 high card points Shows balanced distribution.
    Note: Many bidding systems incorporate a weak No Trumpwith varying point count ranges. The range of 13-15 high card points remains the highest of these modified bidding systems and is occasionally designated as the strong weak No Trump.
2 : 11-15 high card points Promises 5-card plus Club suit.
    Note: This opening bid promises either a distribution of a 5-card minimum Club suit and a 4-card Major suit, or shows a distribution with at least a 6-card Club suit.
2 : 11-15 high card points Distribution: either a 4-4-4-1 distribution with a singleton Diamond, or promises a 5-4-4-0 distribution holding with a void in Diamonds.
2 : 6-10 high card points Promises a 6-card plus Heart suit.
    Note: The difference, in general, between the original version and modified versions lies in the preemptive bids. The modified versions consider the point count of 8-10 high card points preferable.
2 : 6-10 high card points Promises a 6-card plus Spade suit.
    Note: Again, the difference, in general, between the original version and modified versions lies in the preemptive bids. The modified versions consider the point count of 8-10 high card points preferable.
2NT: 22-24 high card points Shows balanced distribution.
