The Precision Diamond system provides a solution to the flaws in the Standard American bidding convention (SAYC). There are 6 notable features of my bidding system. The 1st feature is the ability of the responder to show his 5-card major suit immediately using the Casey-Jacoby Transfer. The 2nd feature is that Precision Diamond permits the opener to show his points within a 2p range from 16-21 points using the Casey Shift and the Strong 2 opening. The 3rd feature is the ability of the overcaller to show his 4-card major suit immediately by assigning 1NT to show 4s. The 4th feature of Precision Diamond is the ability of the Keycard-Asker in a slam contract to ascertain whether the opener has the trump queen using the Casey RKC method. The 5th feature is the ability of the opener to show keycards, including the trump queen, at the 4-level in the case of a minor suit slam attempt using Minorwood. The 6th feature is the ability of the opener to find a slam with a minor suit fit using the Casey Minor Rebid convention.

This book incorporates the 2/1 Game Force bidding system for opening majors and the Casey Simplified Precision Club system for opening minors. This book simplifies the traditional Precision Club system by eliminating many of its unnecessary complications. You will only need to add one new convention, the opening 1 bid, to your Standard American system. This system enables the responder to know the opener’s point count within a 2p range after the opener’s rebid. In addition, the Casey Overcall will improve your part scores by hampering the opponents from finding their spade fit. The book will also help you reach a new level by improving your slam bidding. The advantage of using the Casey Bidding System is that you will open the hand 12.6% more often than with Standard American. Ken has published more than 15 bridge books.

The second edition of this book incorporates the 2/1 Game Force bidding system. The book is designed to improve your bidding in 5 steps. The 1st step involves maximizing your use of the 2/1 system whenever you open with a major suit. The 2nd step involves your use of the New Minor Forcing convention to find a 5-card major in responder’s hand. The 3rd step involves adoption of the strong 2 bid, a bid of 20-21p with an unbalanced hand (one with a singleton or void). By tweaking reverses, this allows the opener to show an unbalanced hand by bidding at the 2-lelvel with 16-17p or at the 3-level with 18-19p. The 4th step involves optimizing your slam bidding with conventions to show the trump Queen. It also involves the use of the Redwood kickback convention minor suit contracts and the use of the Fourth Suit Forcing convention to ascertain whether the opener has 4or 5 cards in this 2nd bid suit. The 5th step involves the use of bids to hamper the opponents from finding their 4-4 spade fit. This involves the use of the Casey overcall and the use of the Casey-Jacoby Transfer for R’s 5-card majors. Finally, the use of inverted minors is discussed.

This book incorporates the 2/1 Game Force bidding system whenever the opener bids a major suit. This book is designed to improve your bidding of minor suit openings in 3 steps. The 1st step involves bids to hamper the opponents from finding their 4-4 spade fit. This involves the use of the Casey overcall and the Weak 1NT opening. It also involves the use of the Casey-Jacoby transfer to find a 5-card major in responder’s hand and the use of inverted minors. The 2nd step involves adoption of the strong 2 bid, a bid of 20-21p. This allows the opener to use the Casey Reverse to show a hand of 16-17p by bidding at the 2-level and to show a hand of 18-19p by bidding at the 3-level. The Casey Minor Rebid convention allows the opening to show a 4+ card suit at the 2 or 3-level. The third step involves optimizing your slam bidding with the Casey Trump Queen convention. It also involves the use of the Redwood Kickback convention for minor suit contracts and the use of the Fourth Suit Forcing convention to ascertain whether opener has 5 cards in his 2nd bid minor suit.

This book is designed to highlight the flaws in Standard American bidding, i.e. the SAYC system. The book discusses the major failures of SAYC, namely the failure of the ACBL to adopt the Bergen point-count system, the failure to simplify reverses, the failure to find a 20-21p bid for all hands, and the failure to adopt the Casey-Jacoby Transfer convention and the Casey Rebid convention. In addition, the book points out numerous minor failures such as the failure to find a means of bidding a direct game, the failure of SAYC to require takeout doubles to have a four-card major, and the failure to adopt Minorwood, a six-keycard kickback convention. The book also points out the ACBL’s failure to clarify certain issues, such as the failure to clarify O’s reply to R’s two-level response, the failure to clarify cuebids, and the failure to clarify Stopper-Ask bids. The book provides a solution for all these problems in a new system called Precision Diamond.

This e-book present some of the most important bridge bidding systems used used in duplicate bridge tournaments, detailing the most known bridge bidding system, Standard American Yellow Card, by using a logical sequential order for openings, answers, competitive bids and defensive play in order to help the players during the games. Much of the complexity in bridge arises from the difficulty of arriving at a good final contract in the auction. A bidding system in contract bridge is the set of agreements and understandings assigned to calls and sequences of calls used by a partnership, and includes a full description of the meaning of each treatment and convention. Standard American Yellow Card is a specific set of partnership agreements and conventions, using Standard American as a base. Standard American Yellow Card is a very specific collection of agreements, which can, of course, be modified and augmented by partnership agreement. In practical use, the term is often mis-used to refer to Standard American in general, or it could refer to a system that used SAYC as a base and made additional augmentations or changes to the base agreements.
