  • 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 .

  • Roman Keycard Blackwood (Part 1) by Fred Gitelman
    Roman Keycard Blackwood (Part 1) By Fred Gitelman The Blackwood convention was developed about 60 years ago by Easley Blackwood of Indianapolis, one of the great Bridge players and theorists of his time. The purpose of the Blackwood convention is to find out how many Aces and Kings your partner holds in order to make slam bidding more accurate. Here's how it works: In most auctions a bid of 4NT is the Blackwood convention and carries the message, “I am interested in slam, partner, how many Aces do you have?” The responses are: 5 Clubs = I have either zero Aces or all four Aces 5 Diamonds = I have one Ace 5 Hearts = I have two Aces 5 Spades = I have three Aces Subsequently the 4NT bidder can bid 5NT to give this message, “We have all four Aces between our two hands, partner. I think we might have a grand slam, however, so please tell me how many Kings you have!” The responses are similar: 6 Clubs = I have either zero Kings or all four Kings 6 Diamonds = I have one King 6 Hearts = I have two Kings 6 Spades = I have three Kings Over the years, Blackwood has gradually become accepted as part of “standard” bidding. Experts eventually developed ways for showing voids (which can be just as important as Aces) in response to Blackwood, and for responding to Blackwood when the opponents interfere over the 4NT inquiry. Several variations of Blackwood were also developed in which the responder was able to show the specific Aces that he held.
