  • Update to Jorj Club System
    Jorj Club system ♠♥♦♣ George Cuppaidge 2014 Re-edited in Nov 2014. A new feature enables users to distinguish between a 6-9 point, and a 10-12 point response to 1C, at the one-level when balanced, or at the level of two of the suit with 5+cards it. See 3.1. This complements the system’s means of distinguishing a 6-9 point 3-card raise of 1D, 1H or 1S from a 10-12 point raise, below the level of two of the suit. 1.0 Introduction. This is a five-card major system. It is a relay system but the natural framework means it can be played without relay continuations. This system is virtually convention free. It is directed at bidding the hand you hold. Logically, it is impossible to do better than that. The opening bids are limited both in strength and in the shapes they may contain. The range of pass is 0-9 points. Whether you are locked in a part-score battle or searching for a key queen for that grand slam, you will outdo your standard- playing opponents consistently. You will know more about what is going on than they do. The system enables you to find exact hand-shape, without which really accurate slam bidding is impossible. Three-suiters and 45+shapes, which are ignored in standard bidding, are bid with certainty in this system. The system strong bid is 1NT. This is the opening bid for all 20+point hands. It will be seen that the single extra step, compared to the more common 2C, makes bidding easier and more accurate.

  • Responder's Strategy
    RESPONDER’S STRATEGY Suit Quality Test for Responder Just as the Suit Quality Test is useful for overcalls, pre-empts and opener's rebid, so it can be used for responses and responder's rebids. WEST EAST Responder's immediate jump to game 1 4 should be based on a hand with seven WEST EAST playing tricks, about 6-9 HCP and a 7+ suit 1 4 which has a Suit Quality of 10+ Beware of the 1 : 4 sequence if you are using that as a splinter raise of spades. With a single-suiter (6+ suit) and 10 HCP or more, prefer to start with a simple change-of-suit response. WEST EAST Jump-rebid your suit to the three-level 1 1 with 10-12 points and a suit quality below 1 3 10. WEST EAST Jump-rebid to game in your major with 10- 1 1 12 points and a suit quality of 10+. 1 4 W E EAST (1) EAST (2) 1 1 K Q 8 6 5 3 K Q J 10 5 3 2 ? A 6 2 A 6 2 8 2 J 2 Q 7 6 3 With (1), rebid 3 . The suit quality of the spades is only 8. With (2), you have a suit quality 10 and should therefore rebid with a jump to 4 . Once you hit 13 HCP or more with a strong single suiter, your rebid will depend on whether opener made a narrow range rebid (e.g., rebid of suit opened) or with a wide-range rebid (change of suit).

  • System for Wayne & Andrei
    Symmetric The Symmetric Relay Contract Bridge Bidding System Made Easy by Andrei Sharko Symmetric © 2004 Andrei Sharko See page 51 for licence ⎯⎯⎯ · · · ⎯⎯⎯ PREFACE In 1980 Walter Jones and Roy Kerr published a book called Symmetric Relay. It was nothing less than a work of genius. It described a bidding system ahead of its time. With their methods it was possible within just a few bids to describe the exact hand shape you held. In fact their sys- tem was so far ahead of their time that their work did not attract the at- tention it deserved. A reading of their book, however, reveals authors that were not out to convert but rather share the fruit of their labour. By the 1990’s it became apparent that the time was overdue for a second edition of Symmetric Relay. Not that there was anything fundamentally wrong with Symmetric Relay. Rather the years of experience playing Re- lay have resulted in a natural evolution of refinements. What I hope to achieve in this book is a basic repetition of the core of Symmetric Relay with those refinements. Also some aspects are left out. One such area is some of the theoretical discussion. That has its place and I recommend the original Symmetric Relay to anyone with an inter- est in bidding theory. There is also a practical aspect: by understanding the reasons for a particular sequence the bidding can be more easily memorised. My intention is that the explanation of bidding sequences is limited only to their practical value. The emphasis in this book is to teach Symmetric Relay.
