La Jolla Bridge (Unit 526)

Welcome to the website for ACBL Unit 526 (U526). We are the La Jolla and Beach Unit in District 22 (D22) of the American Contract Bridge League (ACBL). Our games are held at 1 PM on the second and fourth Sundays of each month at the Soledad Club at 5050 Soledad Road in Pacific Beach (See also the Interactive Google Map of major San Diego clubs). We tradeoff the occasional fifth Sunday with San Diego Unit 539. If you play bridge but are unfamiliar with duplicate (tournament) play, check out Karen Walker’s introduction. Completely new to the game? Check out the ACBL’s Learn to Play web page.

2015 Election Results

Election

Five unit board terms expired in June. At our Annual Meeting and Election game on June 14th, Lynne Anderson and Ron Ignelzi were reelected to a 2015-2017 term. Bob Brobst, Val Frager, and Mary Scott Knoll joined the board bringing us back up to our full strength of ten board members.

The unit board will elect its 2015-2016 officers at the July board meeting.

Bob Brobst had a successful run betting on horses for profit. His first love is tennis but bridge is a close second. He has been playing with Matthew Kidd at the Soledad Club Thursday night game for several months and at other locations around town. Val Frager is a regular at the Beach and Tennis Club, has helped with the La Jolla High teaching for the last three years, and co-chaired our January 2015 NLM sectional with Ron Ignelzi (tournament report). Mary Scott Knoll switched units to serve on our board. She is president of the local chapter of the Aztec Bridge Club, has served on the San Diego unit board as NLM tournament chair, was the major driver for the Shuffle, Deal, and Cook youth bridge fundraiser, and is a Soledad Thursday night regular, partnering with Thomas Burgeson.

The new members bring a welcome diversity to our board which should allow us to better serve our entire unit and the greater San Diego bridge community, both existing and yet untapped. I believe this will translate into concrete action; for example by hosting a Learn Bridge in a Day session within our unit.

Evening Bridge Is Dying, Help!

Downward red arrow superimposed on a picture of the night sky

After the Soledad Thursday evening game dipped to just four tables (financial break even) for four consecutive weeks in May and June, I asked ACBL headquarters to provide national data on evening bridge table counts. The prognosis for evening bridge is grim. Though total club table count has remained nearly constant for the past 25 years, the percentage of those tables played in the evening has fallen from 44% to 16% over the same time period. Utter annihilation of the evening game looks certain within 15 years but collapse due to low table counts will probably occur within half this projected timeframe. See the data and plots.

Keep evening bridge alive in San Diego! Join us at the Soledad Club at 7 pm every Thursday. We are a fun group and we’ll sharpen your bridge skills.

Anne Terry Update

Good news: the evening after my report at the June 14th San Diego unit game that Anne Terry had stopped eating two weeks prior, her daughter sent me this update:

Mom is back! Somehow with the care of hospice and the gals at the house, Mom has made a miraculous recovery. Those German genes won't stop! Guess they are pretty darn strong! As the hospice nurse told me: it will be like a roller coaster ride! So we are on it!

Trish Lane’s Recipes

Players have really enjoyed Trish Lane’s hospitality offerings at our unit games and some have asked for recipes. Trish reveals three recipes.

Unit Zero Tolerance Form

In May we had a Zero Tolerance incident at our unit game. I am happy to say it did not involve one our regular players but I was disappointed to see it happen at all. Although the unit had previously upheld its commitment to the Zero Tolerance policy and was prepared to take action, the complaintant requested that we not do so. However, during the ensuing discussion it became apparent that the unit was remiss in not have a Zero Tolerance report form. As a result we have created a form, modeled after the San Diego unit’s form. Printed copies will be available at unit games and it can also be downloaded from the unit website via the Resource → Zero Tolerance Form menu.

Field Protection, Diversity, and Shannon Entropy

Is field protection a meaningful concept? Does a stronger field provide greater field protection? How many unique results are there on a typical board in a big field? How large does a pair game have to be to avoid undersampling? Take a mathematical journey and find out.

New Tournament Flight: Mid-Flight

The ACBL is experimenting with a new flight for pairs events, called the Mid-flight, that would fit between the Gold Rush (0-750) and the open flight. Recall that flighted events are separated whereas the players in a stratified event play each other but are ranked in their strat and all higher strats for the purpose of awarding masterpoints. A typical mid-flight event would have an upper limit of 3000 MP and strats of 1500 and 3000 MP. The second change is the addition of a third strat to open A/X events. Typical strats might be 1500, 3000, and unlimited.

I take a dim view of Mid-flight. At some point players need to grow up and face real opponents. This should be the Gold Rush Graduation. Adding a third strat to open events is a great idea so long as all the players in the lowest strat aren’t drawn away by Mid-flight events. This gives new graduates a chance to continue winning masterpoints, a necessary motivation for some, while being exposed to serious bridge.

NABC Fund-Raising Game Money Grab

Should D22 players financially subsidize NABC hospitality for the Fall 2017 San Diego NABC? It doesn’t seem logical to me. Read more.

Phyllis Pankow, Irv Gold, and Gail Whiteley

Irv Gold
Irv Gold

Phyllis Pankow, Irv Gold, and Gail Whiteley all passed away in June.

Phyllis was 88 when she passed away on June 8th. She had a regular partnership with Betty-Jo Petersen at our unit game and with Ralph Baty on Thursday nights at the Soledad Club until Ralph passed away last summer. She had also regularly partnered with Mary Anne Scott and Alice Leicht and also with Elizabeth Garber, Jeffrey Holmes and Vi Breckenridge at AIB.

Irv Gold was 73 when he pass away on June 9th. He lived in Carmel Valley but played regularly in our unit game in 2013 and 2014, often partnering with Valerie Gwin.

Gail Whiteley lived in San Marcos.

ACBL Partnership Desk

The ACBL has a new online partnership desk. It works for all ACBL sanctioned events, including tournaments, clubs games, and even unit games. Try the U526 unit game link (ACBL login required). The Partnership Desk functionality is new but please give it a try. I had Bruce Knoll at ACBL headquarters run some database queries for me. 60,000 of you have logged into the ACBL at least once since the ACBL website was overhauled last summer, which works out to almost exactly half the players who have attended at least one tournament since that time. You probably logged in to check your masterpoints. Get ready to do more on the ACBL website.

Review of Innovative Slam Bidding

Cover of Innovative Slam Bidding book

Even world class players only bid about half the available double dummy slams at team play where slam bidding can result in a game swing. Life masters in pair events are only bidding 28% of their slams. Irwin Landow thinks we can do better. Read more about his book Innovative Slam Bidding.

ACBLmerge 1.3.5 is now available

ACBLmerge 1.3.5 fully supports Mac OS X out of the box just like Windows.

After more than two years, a new release of ACBLmerge (1.3.4) is now available. Important changes include: (1) numerous bugs fixes in the par calculation (thanks in part to the careful eye of local Randy Dougherty), (2) 30% faster double dummy calculations, (3) replacement of revoked LHA-Archive package with 7-zip, (4) faces will no longer jump around anymore when different sized images are used for the Face View feature, and (5) clicking on a board number on a popup recap will move the main report to that board as if you had clicked on a board number link at the top of the main report.

Programmers may be interested in the new ACBLgamedump utility for directly reading ACBLscore game files. This utility is tied to the future of ACBLmerge.

Lead Solver is also now bundled with the latest version (2.8.0) of Bo Haglund’s double dummy solver (DDS) for a 40% speed improvement over the original Lead Solver and it now runs on Mac OS X and Unix/Linux as well as Windows.

*You might receive the masterpoint award shown at the club after the game or the 30% higher award shown here from Monday noon onward. Normally we have run a Club Membership game, where one is permitted per year, at our Annual Meeting and Election. But recent ACBL changes may now treat us strictly as a Unit rather than both a Unit and a Club. We are waiting for clarification from the ACBL on this matter in regards to the Membership Game.

ACBLmerge 1.3.5 was released on November 19, 2014. It adds full support for Mac OS X. ACBLmerge 1.3.4 was released on November 7, 2014. This is primarily a bug fix release, including the fix of several bugs in the par calculation. Double dummy calculation is now faster and clicking on a board number in the recap sheet navigates to that hand in the main report. Read more.

Since December 2011, Philippe Lamoise, a bridge player in the North County unit, has been developing the Bridge Results website and I have been making many improvements to ACBLmerge to integrate with the functionality provided by his website. Now it is easy for club directors, club managers, and tournament officials to upload game results using a web interface without knowing anything about running ACBLmerge. Read more about Bridge Results.
