Precision Club USA Bridge.com What it’s all about: The Basics of the Precision Club Bidding System by O. Johnson The Precision Club bidding system was invented in the 1960s by C.
She demands that 'Any man of mine/better walk the line,' tells a poor sap that '(If You're Not in It for Love) I'm Outta Here!' Shania twain the woman in me video. Together, they totally reworked Twain, turning her into a bold, brassy, sexy, sassy modern woman, singing songs that play like tongue-in-cheek empowerment anthems even when they're about heartbreak. Based on that, Lange didn't seem like an ideal match for Twain, but they turned out to be expertly matched collaborators and romantic partners, too; they married as they were working on the material that became her second album, The Woman in Me. Not long after that, her path crossed with Robert John 'Mutt' Lange's, the producer behind some of the greatest albums in hard rock history, including AC/DC's Back in Black and Def Leppard's Hysteria.
Wei of Taiwan. The original objective of the system was to help the Taiwanese national team compete against expert bridge players from around the world. It was very successful. After the initial successes of the Taiwanese team, many bridge players adopted the system. Precision Club is a system designed to help bridge partners better describe their hands to one another. But, the system does require a good understanding of the system by both members of a partnership.
It is a system that can be very rewarding if the players learn and practice the bidding conventions on a regular basis. The author, O. Johnson, and his wife, Karen, have played the Precision Club system since the 1970s. Even though they have limited their tournament play to just a few times per year, they have both achieved Bronze Life Master status in the American Contract Bridge League.
Intro to Precision The Precision Club Bidding System was invented by CC Wei, a Chinese businessman, in the late 1960s and was first used on the international stage by the Taiwan national team in 1970. Following their success using the system in the 1970 and 1971 Bermuda Bowls, Precision exploded onto the world stage when the legendary Italian Blue Team adopted and refined it as Super-Precision.
The Blue Team's successes during the 1970's using Precision brought the system prominence and prestige. Although its global popularity will never rival that of Standard American, 2-Over-1 or Acol, it is generally reckoned to be more efficient that any of them and is the foremost Strong Club system in use today. Many modern experts, including multiple World Champions Jeff Meckstroff and Eric Rodwell use it as the basis of their system. The number of other Strong Club systems that have come into existence since 1970, and which use Precision as their basis, are a further testament to its power and effectiveness. Basic System Strategy Precision gains its biggest advantage by restricting the range of its intermediate opening bids to 11-15 points and reserving the One Club opening for almost any hand containing 16 or more points.
This contrasts with the huge range for opening bids found in most other systems of 11-20 points. The much smaller range of intermediate openings makes it much easier for Precision users to know immediately whether they are in part-score, game, or slam territory and reduces the strain on Responder to keep the bidding alive in case partner has a rock-crushingly strong hand. Classic Wei Precision specified 5-card Majors, 11-15 Intermediate Openings, a 13-15 Opening 1NT, and 1♣ showing almost all hands containing 16+ hcp. The main features of Standard Precision are as follows:.
13-15 Opening Bid. Artificial Bid to show any 16+ Hand., & Natural showing at least a 5-card suit and 11-15 HCP.
Forcing 1NT Response to 1 ♥ or 1♠ Openings. shows 11-15 and not suitable for one of the other openings. Opening shows 11-15, and exactly 4414 shape with a diamond shortage. Openings. 2NT shows a strong balanced hand. Standard 3 and 4-level Pre-empts.
Origins of OCP The Precision System that I teach on Bridgebase owes much of its essential structure to the Super-Precision system I first developed with Bob Bradbury in the late 1970's and early 1980's. That early system was essentially Standard Wei Precision with the Asking Bids described by Eric Jannerstern in his excellent book on Precision tacked onto it, with a few bells and whistles. In the late 1980's, Jason Hackett and I took that system apart and rebuilt it into what is now known as the OCP Complex System, with a totally new and non-standard set of responses to 1 ♦ and non-standard openings above 2♣. The 'Simple System' retains the extensive use of Lebensohl and Lebensohl-style extensions in natural bidding sequences, the extensive use of Asking Bids when one or both hands is strong, and a preference for 4-way transfers and some specialised sequences over 1NT and strong balanced openings.

There are now, however, a number of pairings amongst the OCP group who regular play the whole Complex version of OCP pretty much as Jason and I used to play it, but including the more recent developments. Other Features Beyond these features, Precision users are pretty much free to bolt on whatever other features they like. Although, for example, Standard Precision specifies the use of 2-way Stayman rather than transfers, many Precision users opt for the latter and this can be done without affecting other areas of the system. Similarly, many Precision Pairs opt for a non-standard scheme of Openings from 2 ♦ upwards, but these kinds of changes do affect other areas of the system such as the 1 ♦ Opening. Asking Bids are an area that some users of the system do not touch, choosing to rely on more conventional tools such as cue-bids and Roman Key-Card Blackwood. Precision specifies little or nothing where defensive bidding is concerned. Oneof Precision's great strengths is the extent to which you can adapt and extend it.

It is undoubtedly one of the main reasons why it has become so popular. The successes of Precision on the world stage are a testament to its effectiveness.
Jeff Meckstroth and Eric Rodwell, certainly one of the greatest Bridge partnerships of recent times, have shown how far you can extend Precision whilst still keeping its essence intact. OCP More Recently OCP has not stopped being developed at any point since 1980 when Bob Bradbury and I first started actually playing the original version (which back then was pretty much standard Precision with the Asking Bids bolted on). Jason Hackett and I integrated the Asking Bids much more into the basic fabric of the system, developed a lot more of the specific enquiry sequences and streamlined slam investigation over the Intermediate Openings.
Once OCP moved into the Online Bridge sphere, OCP regained some freedom to be the system as Jason and I had planned it (since online play was free of the strictures of the EBU). Since 2000 we've added one complete new Asking Bid (Sigma) and modified most of the rest to a greater or lesser extent. Relay Beta, which Jason and I had created for use in slam investigations over Major Suit Openings, is now used system-wide. Most recently (December 2016), we've just completely re-written the responses to the Simple System's 2 ♦ Opening. Besides those major system upheavals, there are a whole host of smaller tweaks that have been applied over the years.
