Introducion to Duplicate
INTRODUCTION to DUPLICATE INTRODUCTION TO DUPLICATE BRIDGE This book is not about how to bid, declare or defend a hand of bridge. It assumes you know how to do that or are learning how to do those things elsewhere. It is your guide to playing Duplicate Bridge, which is how organized, competitive bridge is played all over the World. It explains all the Laws of Duplicate and the process of entering into Club games or Tournaments, the Convention Card, the protocols and rules of player conduct; the paraphernalia and terminology of duplicate. In short, it’s about the context in which duplicate bridge is played. To become an accomplished duplicate player, you will need to know everything in this book. But you can start playing duplicate immediately after you read Chapter I and skim through the other Chapters. © ACBL Unit 533, Palm Springs, Ca © ACBL Unit 533, 2018 Pg 1 INTRODUCTION to DUPLICATE This book belongs to Phone Email I joined the ACBL on ____/____ /____ by going to www.ACBL.com and signing up. My ACBL number is __________________ © ACBL Unit 533, 2018 Pg 2 INTRODUCTION to DUPLICATE Not a word of this book is about how to bid, play or defend a bridge hand. It assumes you have some bridge skills and an interest in enlarging your bridge experience by joining the world of organized bridge competition. It’s called Duplicate Bridge. It’s the difference between a casual Saturday morning round of golf or set of tennis and playing in your Club or State championships. As in golf or tennis, your skills will be tested in competition with others more or less skilled than you; this book is about the settings in which duplicate happens. -
Slam Bidding Lesson
Slam Bidding and Modified Scroll Bids By Neil H. Timm In this Bridge Bit, I explore more fully Slam bidding techniques, some old and some perhaps new. To reach a small slam, the partnership should have roughly thirty-three Bergen points. In addition to a trump fit and count, slams require controls (aces, kings, voids, and singletons). The more controls between the partners, the easier the slam. To evaluate whether or not the partnership has the required controls, one uses cuebids with perhaps the 5NT trump ask bid (Grand Slam Force), and Blackwood Conventions. Blackwood Conventions reveal how many aces and kings, while cuebidding or control showing bids reveal where they reside. To make a slam, one usually requires first-round control in three suits and second round control in the fourth suit. It is possible to make a slam missing two aces, provided the missing ace is opposite a void, and the second missing ace is replaced by or is opposite a second-round control (a king or a singleton). When looking for a possible slam, one often asks the following questions. 1. What cards should my partner have to be able to make a slam? 2. How may I obtain the required information? 3. Are there any bidding techniques or conventions that I can use to obtain the required information? 4. If my partner does not have the required cards for a slam, can I stop short of slam, and if not is the risk of going down worth it? We shall review techniques to help the partnership find the required information for making a slam! However, with some hands one needs only to count points to reach a slam. -

Acol Bidding Notes
SECTION 1 - INTRODUCTION The following notes are designed to help your understanding of the Acol system of bidding and should be used in conjunction with Crib Sheets 1 to 5 and the Glossary of Terms The crib sheets summarise the bidding in tabular form, whereas these notes provide a fuller explanation of the reasons for making particular bids and bidding strategy. These notes consist of a number of short chapters that have been structured in a logical order to build on the things learnt in the earlier chapters. However, each chapter can be viewed as a mini-lesson on a specific area which can be read in isolation rather than trying to absorb too much information in one go. It should be noted that there is not a single set of definitive Acol ‘rules’. The modern Acol bidding style has developed over the years and different bridge experts recommend slightly different variations based on their personal preferences and playing experience. These notes are based on the methods described in the book The Right Way to Play Bridge by Paul Mendelson, which is available at all good bookshops (and some rubbish ones as well). They feature a ‘Weak No Trump’ throughout and ‘Strong Two’ openings. +++++++++++++++++++++++++++++++++++++ INDEX Section 1 Introduction Chapter 1 Bidding objectives & scoring Chapter 2 Evaluating the strength of your hand Chapter 3 Evaluating the shape of your hand .

These are extra points, beyond those for tricks bid and made, awarded for holding honour cards in trumps, bonuses for scoring game or slam, for winning a rubber, for overtricks on the declaring side and for under-tricks on the defending side, and for fulfilling doubled or redoubled contracts. ACOL/Acol A bidding system commonly played in the UK. Active An approach to defending a hand that emphasizes quickly setting up winners and taking tricks. See Passive Advance cue bid The cue bid of a first round control that occurs before a partnership has agreed on a suit. Advance sacrifice A sacrifice bid made before the opponents have had an opportunity to determine their optimum contract. For example: 1♦ - 1♠ - Dbl - 5♠. Adverse When you are vulnerable and opponents non-vulnerable. Also called "unfavourable vulnerability vulnerability." Agreement An understanding between partners as to the meaning of a particular bid or defensive play. Alert A method of informing the opponents that partner's bid carries a meaning that they might not expect; alerts are regulated by sponsoring organizations such as EBU, and by individual clubs or organisers of events. Any method of alerting may be authorised including saying "Alert", displaying an Alert card from a bidding box or 'knocking' on the table. Announcement An explanatory statement made by the partner of the player who has just made a bid that is based on a partnership understanding. The purpose of an announcement is similar to that of an Alert. -

Offense to Defense Ratio (ODR) by Neil H
Evaluating Your Offense to Defense Ratio (ODR) By Neil H. Timm Duplicate Match-point Bridge is all about bidding in competition and how many tricks each side can take. However, you do not want to outbid the opponents if the penalty you earn is more than the value of the contract they would have earned. If you can make eight tricks in hearts and they can make eight tricks in spades, and they bid 2♠, then you should bid 3♥ if you know with some certainty that you can expect to go down by at most ONE trick since to score of -50 or -100 is better than the 110 that their 2♠ contract would produce, bid to the 3-level; since any positive difference (even 10 points) to the majority of the field is decisive in terms of match points. Even two tricks down for a score of -100 is fine if not vulnerable; but if vulnerable a score of -200 is clearly bad so you may not want to outbid them when vulnerable if you were to get doubled. The challenge is to accurately evaluate how many tricks you and the opponents can take. Remember that the aim of competitive bidding in regular match-point pairs is not to bid what you can make. Rather you are striving for the best possible score on the board, the par score, even if that means bidding to go down - provided it scores better than allowing the opponents to make their contract. Therein lies the rub since most of the methods used do evaluate the number of tricks do not guarantee success because “success” depends upon high-card strength, shape, the distribution of HCP values, and suit quality.
