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 .

DUMMY REVERSAL By: Brian Gunnell
BRIDGE BITES from The American Contract Bridge League DUMMY REVERSAL By: Brian Gunnell ♠ 8642 E-W Vulnerable ♥ KQ9 South West North East ♦ KJ6 1♥ 2♠ 3♠ Dbl ♣ AKQ Rdbl Pass 4NT Pass ♠ AQJT53 North ♠ K97 5NT Pass 7♥ All Pass ♥ 542 West East ♥ 6 ♦ T42 ♦ 9873 N-S do well to reach 7♥. North’s 3♠ said “Good hand with Heart support”, ♣ 4 Declarer ♣ J9853 South’s Redouble showed a control in ♠ Spades, 4NT asked for Aces, and the ♥ AJT873 5NT response said “Two Aces and a ♦ AQ5 void”. That void was clearly in Spades, ♣ T762 so North took a shot at the grand slam. Trusting that the ♠A was not cashing, West led a trump, at which point Declarer could see 12 top tricks. The 13th might come from the Club suit (if the Jack would come down in three rounds), or, if trumps were 2-2 then the 13th trick would come from a Club ruff in Dummy. As you can see, both these lines of play were doomed to failure, but there was a another line available, in the form of a so-called dummy reversal. Instead of counting six trump tricks in her hand plus maybe a single (Club) ruff in Dummy, Declarer reversed her thinking and went for no fewer than four Spade ruffs in her own hand. Here’s how the play started: opening trump lead won in Dummy, Spade ruff, trump to Dummy (East showing out, and putting paid to any ideas of a Club ruff in Dummy) and another Spade ruff. Back to Dummy with a Club, another Spade ruff, back to Dummy with the ♦J, and a fourth Spade ruff. -

Chicago Wilderness Region Urban Forest Vulnerability Assessment
United States Department of Agriculture CHICAGO WILDERNESS REGION URBAN FOREST VULNERABILITY ASSESSMENT AND SYNTHESIS: A Report from the Urban Forestry Climate Change Response Framework Chicago Wilderness Pilot Project Forest Service Northern Research Station General Technical Report NRS-168 April 2017 ABSTRACT The urban forest of the Chicago Wilderness region, a 7-million-acre area covering portions of Illinois, Indiana, Michigan, and Wisconsin, will face direct and indirect impacts from a changing climate over the 21st century. This assessment evaluates the vulnerability of urban trees and natural and developed landscapes within the Chicago Wilderness region to a range of future climates. We synthesized and summarized information on the contemporary landscape, provided information on past climate trends, and illustrated a range of projected future climates. We used this information to inform models of habitat suitability for trees native to the area. Projected shifts in plant hardiness and heat zones were used to understand how nonnative species and cultivars may tolerate future conditions. We also assessed the adaptability of planted and naturally occurring trees to stressors that may not be accounted for in habitat suitability models such as drought, flooding, wind damage, and air pollution. The summary of the contemporary landscape identifies major stressors currently threatening the urban forest of the Chicago Wilderness region. Major current threats to the region’s urban forest include invasive species, pests and disease, land-use change, development, and fragmentation. Observed trends in climate over the historical record from 1901 through 2011 show a temperature increase of 1 °F in the Chicago Wilderness region. Precipitation increased as well, especially during the summer. -
Bridgehands Emag Newsletter Notrump Leads February 2006
BridgeHands eMag Newsletter Notrump Leads February 2006 Dear Michael, For the last few months, we featured two of declarer’s favorite play strategies – the finesse and the promotion play. This month in our first of a two part article, we will explore considerations for the defender to make the best lead when opponents are playing a Notrump contract. There’s more to this game beyond leading your fourth-best card: find out why. With our focus on leads this month, let’s review the Laws when something goes awry on the opening lead. Everyone loves to open a hand for bidding. Last month we learned how the “Rule of 15” gives us another hand evaluation criterion when partner is a passed hand. Now let’s explore the “Rule of 20” - a third hand evaluation method, useful even when partner hasn’t bid. My, partner, you have great shape – referring to your hand distribution, of course! Some hands have cute colloquial names associated with them to describe the shape: Swan, Rattlesnake, Two/Three Suiter, Pancake, (Ugly) Duckling, Freak, and Stiff. Regardless of how you play the cards, use these clichés and you’ll sound like you really know your stuff after you have finished this month's newsletter. Note: Viewing the hands below requires your EMAIL reader to use "fixed fonts" (not proportional). If you have problems reading this document, please view our online web-based copy or Adobe Acrobat PDF file suitable for printing at the BridgeHands website Leads: Trading a promotion for a finesse Last month we investigated scenarios where declarer promoted long suits to establish extra tricks. -
The Rubensohl Convention
Review sheet 61UZ-2 10/01/2021 The Rubensohl convention You will use the Rubensohl convention in response to your partner's 1 NT opening, but after an overcall. Here is the simplified theory of this convention. After a natural overcall 2 ♦, 2 ♥ or 2 ♠ Any level 2 bid is natural Above 2 NT any bid is a Jacoby transfer. 2 NT is artificial (Jacoby for ♣) An impossible Jacoby becomes a Stayman A double is a take-out double : it could be a Stayman with 8 HCP, or show a balanced hand with 8 HCP or more.

Review sheet 61UZ-2 10/01/2021 The Rubensohl convention After a natural level 2 overcall Bidding a suit at level 2 is natural and non forcing : the responder holds a maximum of 7 HCP Doubling is not punitive : A double requires a minimum of 7-8 HCP and most of the time shows a hand with which the responder would have bid 2 NT (with no overcall). -
Leads and Signals
Leads and Signals o All things being equal, we tend to be on defense about half the time; and leading about half of this time o Opening lead frequently sets up the pattern on defense o Cooperation between partners on defense is extremely important — Don’t try to set your opponents all by yourself; enlist your partner in the effort by signaling what you hold — Watch what partner plays and infer defensive approach he is suggesting and cooperate Leading o The key to selecting an opening lead is to listen to the auction and infer what that says about everyone’s hand — Has your partner bid --> Possible indication of suit to lead — Have the opponents bid easily and swiftly to game with no interference and you have near an opening hand --> your partner has nothing and the defense is “up to you” — Have the opponents struggled and found a secondary place to play -- > They may not have enough trump and a trump lead might be appropriate — Do you have “Connected Honors (I.e., an AK)” --> then you might want to lead the honor to see what dummy has and then make your “real” lead — Do you have a series (I.e., QJT9) -- If you can lead enough times, you can eventually drive out their honors Example hand Example hand - Solved Types of Leads o Aggressive/Active -- Use if opponents have side source of tricks o Tapping -- Use when you have length in trump suit; try to make opponents use their trump by ruffing your long suit o High roller leads -- Very aggressive and gambling leads; usually want to use only in team games where payoff for gamble is large; can -

-..•-..-.."- -...,~ ...~.--~,...--- Overcall F It iped.) , Ii 2 3~hpe_ In contract bridge, an overcall is a bid made after an opening bid has been made by an opponent; the term refers only to the :first such bid. A direct overcall is a bid made directly over the opening bid by right-hand opponent; an overcall in the 'last seat' (made over a bid by left-hand opponent and two subsequent passes) is referred to as a balancing overcall. , ...~_ ••' '-'~'_.~_-..'._. -"" .'~".- _'-·_'· ...•..•..•.•_....._• I.,._·~·.I., ..'_·.•.~_..~.''''F.~.•._•..•. _ ., .•....~• "'._'._ .' ._., '. -' ..-.- ", ..-...- -,.- ...-.-..-~..•.......•..... -~..-'-.- ..•. Objectives The overcaller has one or more of the following objectives: • To secure the contract • To suggest a good lead from partner • To induce the opponents to a higher-level contract • To find an effective sacrifice • To hinder the opponents in their bidding Snit overcalls In most bidding systems, an overcall in an unbid suit is natural denoting length and strength in the suit \?id. The common requirements include: •• A good 5-card or any longer suit; the definition of 'a good 5-card suit' is subject to partnership agreement. • 8-16+ high-card points (HCP) for an overcall at the l-level. • 10-16+ HCP for an overcall at the 2-level. • A higher level overcall (e.g., after an opponents' preempt) requires at least opening-bid strength.
