The Optimal Modified 2 1 Club System

My goal for “The Modified Optimal 2/1-Club System” is to show how to use the Optimal Point Count (OPC) method of hand evaluation developed by Patrick. Darricades in his book “Optimal Hand Evaluation” (2019) to improve the dialogue between two players to achieve an optimal bridge contract. The primary objective is to demonstrate how to apply the new system approach to contract bridge by illustrating a more accurate method of hand evaluation whether you play 2/1, Standard American (SA), Acol or Precision, among others. The Two over One (2/1) Game Force bidding system was an improvement over the SA System that has been in effect and played by bridge players for many years. Many claim that the advantage of the 2/1 system allows the partnership to know that game is possible with only a single bid provided one has 13+ points. As we shall see for suit contracts it is only true if the opening 2/1 bidder has 15 points, not 12/13 points since 25/26 points do not result in game whenever a singleton in one hand finds “wasted honor points” in partner’s hand. Yet, most 2/1 conventions call for 13+ High Card Points (HCP). Another flaw of the 2/1 approach is the fact that opening 1-level suit bids have a wide bidding range (12-21). To eliminate this flaw, the principles of Pinpoint Precision with 1*= 18+ points and new responses associated with a new and improved hand evaluation method. A major flaw of most Strong Club opening bids is that they are based solely on HCPs with opening bids of 1*=16/17+ HCP. To correct these flaws among others, the search for a better hand evaluation method and a better bidding system has been unrelenting. Hand evaluation methods have been popularized by Milton Work, Charles Goren, Marty Bergen, and Petkoy Zar, and others. All falling short when applied to the commonly used “dialogue” bidding systems. The Optimal Point Count (OPC) method of hand evaluation corrects the many flaws of prior hand evaluation methods when applied to any bidding system. In this book many “traditional/standard” bidding practices that do not help to show suit fi t and distribution are to be avoided or re-defined. Splinters and mini splinters which show the location of voids and singletons to help locate wasted honors, the XYZ bidding convention, cue bidding, and new bids for the investigation of game and slam are among the cornerstone conventions reviewed in this book. Newly defined 2 and 3-level bids to show hands with 6/7+card suits are defined to prevent the opponents from finding their optimal contract and to improve upon difficult bidding sequences using traditional bidding strategies. The evaluation of one’s Offense to Defense Ratio (ODR), why many well-known bidding sequences must be avoided, and an analysis of several old “standard” bridge laws/rules are reviewed to show why they need not be used to improve one’s judgement if one employs the OPC method.

A collection of the first section of the "Fundamentals of Pure and Applied Economics" series, "Regional and Urban Economics: Parts One and Two" is an encyclopaedia containing eight titles: This volume highlights original contributions in regional and urban economics, concentrating mainly on urban economic theory. The contributions focus on the treatment of space in economic theory. Drawing on the body of literature developed by Von Thunen, Christaller and Losch, these chapters explore empirical, theoretical and applied aspects of urban and regional economics which can be divided into the following areas: Location Theory, "Jean Jaskold Gabszewicz, Jacques-Francois Thisse, Masahisa Fujita "and" Urs Schwiezer" Urban Public Finance, "David E. Wildasin" Urban Dynamics and Urban Externalities, "Takahiro Miyao "and" Yoshitsugu" "Kanemoto" Systems of Cities and Facility Location,

The 2/1 Game Force bidding system is an improvement over the Standard American System that has been in effect and played by bridge players for many years. The advantage of the 2/1 system is that it allows the partnership to know that game is possible with only a single bid. In this book, I have tried to present the fundamental aspects of the bidding structure for playing a pure Two-Over-One Game Force system of bidding. In this book, I have tried to change behavior by presenting a series of bids geared toward the 2/1 bidding structure that includes Bergen, Reverse Bergen, and Combined Bergen Raises, inverted minor suit raises with crisscross and flip-flop, cuebidding, modified scroll bids, and many more methods not used in Standard American or Precision. In the fourth edition, the Minorwood Convention has been expanded and several variations of the Flannery Convention are included in this edition. I have added the Hello and SCUM conventions used to interfer over strong notrumps and a Modified Landy convention designed to compete over partnerships that employ a weak notrump bid. The Equal Level Conversion (ELC) double is discussed in Chapter 6 and additional material on slam bidding has been added to Chapter 3. The material on two-way new minor forcing and the Gazilli Convention has been expanded upon in Chapter 1 and Jacoby transfers with a superaccept structure has been added to Chapter 2. Finally, a new chapter that reviews the new Italian System of bids called Fantunes has been included in this edition. The System has been modified to be in compliance with the General Convention Chart.

This Handbook is essential reading for anyone with an interest in the explanation of economic growth in the space economy. . . The editors and the individual contributors are to be congratulated on producing such an important collection of review essays which is destined to become one of the definitive reference books on the subject. John McCombie, Scienze Regionali . . . offers a valuable up-to-date overview of many aspects of these important theoretical developments. Peter Wood, Environment & Planning B The book contains a wealth of leading-edge material on regional growth and development issues and provides a good historical review of the dominant mainstream theories. This Handbook will be a valuable asset to any graduate student, researcher, regional planner, or policymaker interested in regional economic issues. Laura Lamb, Review of Regional Studies Regional economics an established discipline for several decades has gone through a rapid pace of change in the past decade and several new perspectives have emerged. At the same time the methodology has shown surprising development. This volume brings together contributions looking at new pathways in regional economics, written by many well-known international scholars. The most advanced theories, measurement methods and policy issues in regional growth are given in-depth treatment. The focus here is to collect cutting-edge theories explaining regional growth and local development. The authors highlight the recent advances in theories, the normative potentialities of these theories and the cross-fertilization of ideas among regional economists and mainstream economists. Theories of regional growth and development need to be able to interpret, more than ever, the way in which regions achieve a role in the international division of labour and, more importantly, the way in which regions can maintain this role over time. Topics covered include: regional growth and development policies and measurement methods; development theories of innovation, knowledge and space, and regional production factors; and growth theories and space. This book will be a source of reference and information for both scholars and students in the area of regional economics.

My goal in writing this book is to provide a careful organization of topics so that one may easily convert from any standard two club opening system and in particular the 2/1 Game Force bids to Precision. In the process, one may keep most of their natural bidding sequences and the conventions they currently use with minor modifications. I have tried to eliminate the fear of the memory features used by many variations of Precision by presenting a series of bids that are geared toward simplicity and allow the reader to integrate the Precision system into their more familiar natural bidding system using the 2/1 Game Force bidding structure which includes Combined Bergen Raises, inverted minor suit raises with criss-cross, cue bidding, modified scroll bids, and many more familiar methods.

This book constitutes the refereed post-proceedings of the Third International Workshop on Engineering Self-Organising Applications, ESOA 2005, held in July 2005 as an associated event of AAMAS 2005. The 12 revised full papers and 6 revised short papers presented are organized in topical sections on novel self-organising mechanisms, methodologies, models and tools for self-organising applications, and specific applications of self-organising mechanisms.

Accurately assess the value of your combined hands Accurate hand evaluation is critically important to reaching the right contract in bridge. Yet, for over 75 years now, hand evaluation has essentially relied on Milton Work's 4-3-2-1 honor point count -- a count known to be seriously flawed and inaccurate. Even in balanced hands aces are under-valued, queens and jacks are overvalued, tens are not factored in, and distribution and fit are barely considered. All in all, this method gives a very unsatisfactory, inaccurate point count that leads, too often, to the wrong contract. In this book, the author addresses these flaws by applying corrections to the 4-3-2-1 honor point count and Goren's distribution point count, and introduces revolutionary new findings that lead to much more accurate hand evaluation. Most importantly, this new Optimal hand evaluation accurately assesses the value of both hands combined, the true test of hand evaluation. Over 100 example hands clearly establish that the Work/Goren point count is simply erroneous and that various other more modern methods do not offer a better alternative. Reading this book will let you be the judge, and applying the Optimal point count is sure to substantially improve your bidding.
