Expected In-Behavior Just as all kinds of competitive-type endeavors have their expected in- behavior, so does duplicate bridge. One important thing to keep in mind is that this is a competitive adventure.....as opposed to the social outing that you may be used to at your rubber bridge games. Now that is not to say that you can=t be sociable at the duplicate table. Of course you can.....and should.....just don=t carry it to extreme by talking during the auction or play. -

This was not a casual decision. It was one of the most carefully considered decisions in the book. The Drafting Sub Committee wants there to be no order in the arrangement of the cards when they arrive at the table. Any ordered arrangement is capable of conveying information. This is obviously true if left in the order the cards were played. -

Laws of Duplicate Bridge
Laws of Duplicate Bridge 2016 Revised Authorized Edition Laws of Duplicate Bridge North American Edition As Promulgated in the Western Hemisphere by the AMERICAN CONTRACT BRIDGE LEAGUE Effective September 8, 2008 Published by American Contract Bridge League Distributed by Baron Barclay Bridge Supply ISBN: 978-0-939460-83-0 Library of Congress Catalog Card Number 87-700085 Dewey Classification 795.41 Copyright 2008 by All rights reserved. No part of this book may be repro- duced or utilized in any form or by any means, electronic or mechanical, including photocopying, recording, or by any information storage and retrieval system without permission in writing from the ACBL. Preface to the Laws of Duplicate Bridge 2008 NORTH AMERICAN EDITION The first Laws of Duplicate Bridge were published in 1928 (until 2008 it was titled The Laws of Duplicate Contract Bridge). There have been successive re- visions in 1933, 1935, 1943, 1949, 1963, 1975, 1987 and 1997. Through the Thirties, the Laws were promulgated by the Portland Club of London and the Whist Club of New York. From the Forties onwards, the American Contract Bridge League Laws Commission replaced the Whist Club, while the British Bridge League and the European Bridge League supplemented the Portland Club’s efforts. The 1975 Laws were also pro- mulgated by the World Bridge Federation Laws Com- mission, as they were in 1987 and 1997. The current version is also promulgated in the remainder of the world by the WBF. This latest revision supersedes the 1997 Code on September 8, 2008. Zonal authorities may implement the new Code any time after January 1, 2008 and be- fore September 30, 2008. -

Human-Agent Cooperation in Bridge Bidding
Human-Agent Cooperation in Bridge Bidding Edward Lockhart Neil Burch Nolan Bard Sebastian Borgeaud [email protected] DeepMind DeepMind DeepMind DeepMind Tom Eccles Lucas Smaira Ray Smith DeepMind DeepMind DeepMind Abstract We introduce a human-compatible reinforcement-learning approach to a coopera- tive game, making use of a third-party hand-coded human-compatible bot to gen- erate initial training data and to perform initial evaluation. Our learning approach consists of imitation learning, search, and policy iteration. Our trained agents achieve a new state-of-the-art for bridge bidding in three settings: an agent play- ing in partnership with a copy of itself; an agent partnering a pre-existing bot; and an agent partnering a human player. 1 Introduction Deep reinforcement learning has had great success in two-player, zero-sum games. Key to the suc- cess of the algorithms used for these games is the fact that if neither player can unilaterally improve, the policies must be globally optimal [1], and therefore considering only unilateral policy deviations is sufficient to achieve optimal play. On the other hand, collaborative multi-agent environments have many local optima – agents must coordinate their strategies with each other to perform well. We are particularly interested in human-compatible agents for such domains, because of the general importance of agents that can cooperate with humans. A type of environment where the need for coordination is particularly stark is a communication game; if one agent unilaterally diverges from an agreed “language”, the results are likely to be very poor. The bidding phase of bridge is one such domain, involving grounded communication arXiv:2011.14124v1 [cs.AI] 28 Nov 2020 and competition between two teams of two. -

February / March 2013
THE SUN Seattle Unit 446 Newsletter February/March 2013 2012 Round Robin Wrap-Up by Ray Miller Teams captained by Richard Yarington and Steve Kasner have wrapped up victories in their brackets of the 2012 Seattle Round Robin. Yarington defeated a tough Castoriano team 109-35 in the Open bracket, while Kasner defeated the Matt Schafer team 98-23 to win the 0-750 bracket. The team of John Schermer, Ken Scholes, Kevin Bolan, Bill O’Brien, Richard Yarington, and Leo Schwartz continues to dominate the Round Robin. Online reports of the event go back to 2006 and indicate that they have won every year since then, mak- ing this at least their seventh consecutive victory! One report did contain a vague reference to the team having lost in the finals of the event at some point in the past, improbable though it may seem. This year the perennial favorites secured the final qualifying spot by a margin of only one VP, but dominated once again in the knockout stages. The team of Joel Castoriano, Bob Richardson, Ron Tracy, and David Hildebrand won the qualifying stage and were strong throughout, losing only one match prior to the final. Tying for 3rd/4th were the Rao team (Baluso Rao, Jess Sellers, Jim Aitken, Greg Ho) and Godefroy team (Ole and Julie Godefroy, Carlyn Steiner, Emery Selymes, Roger Urbaniak). In the new 0-750 bracket, the Kasner team lost three very close matches while capturing three big wins in the qualifying stage, but were dom- inant in the knockout stage. The Kasner team is made up of Steve Kasner, Wende Keirsey, Wally Hurst, and Greg Herman.
