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.

Cass Donovan Memorial
Cass Donovan passed away at 6 pm on July 25th. The unit held a memorial for her at noon on Sunday August 9th, an hour before the unit game. Debbie Hedenberg organized the hospitality with help from Judy Elsberry, Judy Hunter, Sydney Jones, and Ann Manaster. Read the memories.
Cass began playing bridge during college in Omaha and took up duplicate bridge in 1997. She has served on the La Jolla unit board since at least 2001, longer than any other recent board member.
Ivar Stakgold becomes an emerald life master
Charlotte Blum, the awards chairman, presented an emerald life master (7500 MP) award to Ivar Stakgold at the July 12th unit game.
Ivar is a mathematician who has done far more than accumulate masterpoints. He holds five national titles: the Silodor Open Pairs, Vanderbilt Knockout Teams, and Reisinger Board-a-Match Teams (all in 1958—what a year!), Spingold Master Knockout Teams (1962), and the Mixed BAM Teams (1969), and has three second place NABC finishes. And he has a 1959 second place finish in the Bermuda Bowl with teammates Harry Fishbein, Sam Fry Jr. Leonard Harmon, Lee Hazen, and Sidney Lazard. He even has a Wikipedia page.
The Platinum LM and Grand LM ranks both require 10,000 MP but the latter requires winning a national title. Holding not one, but rather five national titles and having earned many of his masterpoints before the great masterpoint inflation of the new millennium, Ivar is surely an honorary Grand LM whether or not he sits in a chair for another 2,500 MP.
Even if you have not met Ivar at the bridge table his name may be sound familiar because Ivar is a regular contributor to the It’s Your Call bidding forum of the Contract Bridge Forum newspaper.
Ivar’s mathematical work concentrated on boundary value problems, i.e. scenarios where a continuous (smooth) function is to be determined over a volume given a knowledge of its values or derivatives on a surface. These problems are highly relevant to both classical and quantum physics and have numerous practical engineering applications. One such practical application is the time evolution of the temperature within a solid when heat is applied to the surface of the solid.
2014-2015 Annual Financial Report
The 2014-2015 unit annual financial report is available in summary form with comparisons to the previous three financial years and also in a month-by-month form (, ) showing month-by-month income and expense.
The unit showed a profit of $820.36 for the 2014-2015 year. More than half of the profit ($429.20) was generated by investment income. The unit would like to thank our treasurer Barbara Blake for the careful preparation of these reports and a sensible investment strategy.
May sectional profit was down significantly from the previous year, approximately $400 vs. $1,800 last year. But this was partly offset by a $1 increase in the table fees last November and the stabilization of the average table count at 17.0 for FY 2014-2015 after a concerning dip to 15.6 in FY 2013-2014.
Stanford is runner up in the Collegiate Bridge Bowl
Emily Kelly (far right), unit board member Ursula Kantor’s granddaughter, was part of the Stanford team which was the runner up at the Collegiate Bridge Bowl at the summer NABC in Chicago.
The final against Chicago was close until Chicago gained 38 IMPs on the first five boards of the last quarter and held on to them for the victory.
Seventh year of teaching at La Jolla High
The seventh year of bridge teaching at La Jolla High ran from May 18th through June 11th. Sandra Gagnon headed up this effort for the second year in a row. Read more from Ron Ignelzi, the unit Education Chair.
Evening Bridge Is Dying, Help!
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.
Marvin French resurrected
He is baaaack! Or at least his website is. The webhosting contract for Marvin’s original website lapsed in 2015, a few months after his death. Shortly after Evan Bailey passed away I told Marvin that I had vacuumed up a copy of Evan’s website so that I could re-host it after the webhosting contract lapsed. Marvin was happy to hear that and hoped I would do the same for him after he “kicked the bucket.” So here you go, Marvin!
Marvin French’s many contributions to bridge literature include Squeeze Refresher, his Bidding Handbook (Four-Card Majors: Western Natural Updated), Defense Handbook, AmBIGuous Diamond Bidding System, Skeleton Bidding System, Party Bridge Guide, Beating the Experts, Fairness in Duplicate Pairs Games. Five vs. Four, and other bridge articles. He also wrote about blackjack, literature, and reasoned skepticism.
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.
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.
Greg Chaffee and David Oakley won the Weiss Trophy
Greg Chaffee and David Oakley won the Weiss Trophy at the June 14th Annual Meeting and Election unit game.
This pair also won the Weiss Trophy in 2002. David holds the record for the most number of Weiss trophy wins, having also won the trophy with his wife Pauline in 1976 and David Walters in 2009.
Phyllis Pankow, Irv Gold, Gail Whiteley, Doug Woodworth, Ornette Coleman, and Omar Sharif
Phyllis Pankow, Irv Gold, and Gail Whiteley all passed away in June. Doug Woodworth passed away on July 1st.
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 passed 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.
Judge Woodworth passed away at age 87 from pulmonary fibrosis after a short hospital stay. He had his family with him at the end. Read his obituary. A memorial service will be held at All Soul's Episcopal Church at 10:30 a.m. on Saturday, August 8. It will be followed by a reception at The Thursday Club in Point Loma. The family encourages donations to the San Diego Rescue Mission, The Committee of 100, or a charity of choice.
Ornette Coleman passed away on June 11th at age 85. He wasn’t a bridge player but so what—put down your cards and crank up the The Shape of Jazz to Come (1959). What a badass!, the last of a generation.
Omar Sharif, the Egyptian-born actor known for his roles in Lawrence of Arabia and Doctor Zhivago, passed away on July 10th. He also knew a thing or two about bridge. Asked why he spent so much time at bridge when he could have been making movies, he once replied: “The real question is why I spend so much time making movies when I could be playing bridge.” Memories from the bridge community and Quotes.

Find a unit game partner online
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
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.
Maritha Pottenger’s handouts online
Maritha Pottenger has created many one or two page bridge handouts in the course of teaching bridge in the San Diego area for several years. 42 of them are now available online in PDF form (13 added February 27th). Check back regularly for more.
Marvin French Movement
For the August 9th game, director Marc Matz ran what he is coining as the Marvin French movement. 17 tables is awkward. With 18 tables, the field is normally split into two 9 tables section with 3 board / round so that each pair meets all the other pairs in opposite direction within their section. With 16 tables, 13 rounds of 2 boards each allows each pair to encounter 81% of the opponents in the opposite direction. If 17 tables is split into two sections, one section will play only 24 boards at 3 boards / round or there will be a different number of boards per round in each section which is awkward to direct. If 17 tables is run as a single section, only 76% of the pairs in opposite direction will be encountered, reducing fairness. One solution is run 14 rounds for a total of 28 boards. This requires fast players… but the unit game players proved up to task. For more read Fairness in Duplicate Pairs Games.
Flat as a Pancake
Board 14 from the August 9th unit game was that rarest of results, a completely flat board in a large field. 14 identical results, presumably 4♠ making 5 though curiously N-S can also make 5♥ on their 4-2 fit! Many of the standard conditions for a very flat board are present: clear major suit game (9 card fit) with notrump seemingly inferior (though +660 is available here), and no two way finesses (it’s possible to run the ♣J here and then later finesse the ♣9 if West covers the ♣J but that is a much worse line than simply finessing the ♣J unless you are very sure West has the ♣Q).
August 30th winners: Paul Alesu and Bob Brobst (Flt A+ B + C), John Lagodimos and Kathie Angione (2nd Flt A).
August 23rd winners: Bernard Figueiredo and Hanan Deeby (Flt A), Michael Farber and Myrna Blaufarb (Flt B), Barbara Blake and Patricia Wilkey (Flt C).
August 9th winners: Dorn Bishop and William Bartley (Flt A + B), Robert Mann and Supriyo Dattar (Flt C).

*Revised August 30th at 6:30 pm after four corrections. Scores for Kidd-Lane were on the wrong side for boards 12, 19, and 20 (would someone please teach my partner how to score…) and -650 is corrected to -630 on board 4. These corrections have a minor impact on the rankings. Revised again at 9:30 pm: board 14 had a 480 that had to have been on the wrong side. This change shuffles the top rankings.
**Revised August 24th at 7 pm after three corrections. The +920 score for Shapley-Walters vs. Oakley-Chaffee on board #1 was corrected to +990; the -420 (game on the wrong side) for Gwin-Thumma vs Oakley Chaffee on board #5 was corrected to +620; and the +720 score for Drake2 vs. Loh2 on board #21 was corrected to +620. These corrections slightly change some of the rankings.

ACBLmerge and Bridge Results
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.
