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.

January 2015 NLM sectional tournament report
The January 2015 non-life master (NLM) sectional was our most successful NLM tournament since the unit resumed hosting NLM sectionals in 2012. Ron Ignelzi, the tournament co-chairman, has written a tournament report (includes pictures).

2014 Mini-McKenney and Ace of Clubs results
The 2014 La Jolla Unit Masterpoint Race Winners are final. Anant Rathi also won his Mini-McKenney bracket (300-500) at the district level and placed fourth at the national level. Carol Abramowitz (500-1000), and Elaine Chan (1000-2500) convincingly won their Mini-McKenney brackets. Helen Miller was just behind Frank Fu in the 0-5 Mini-McKenney bracket and Bill Grant was just behind David Abelow in the 5000-7500 bracket.
Despite decades of study, including work by Steve’s esteemed colleagues, science has not found a solution to Bridgeauszeichnungangst, the fear of receiving a bridge award. The pharmaceutical industry estimates a successful drug would increase industry profit by 0.000001%.
Nonetheless, Steve Seagren is now a silver life master. Charlotte Blum presented his award at the December 28, 2014 unit game.
2014 President’s Awards
Continuing his emphasis on partnerships and statistics rather than individuals and what the late great Victor Mollo called monster points, unit president Matthew Kidd presented the second annual President’s awards at the January 11, 2015 unit game based on the unit game results for 2014.
Tolstoy understood bridge players
The dead man lay, as dead men always lie, in a specially heavy way…
He [Peter Ivanovich] felt that Schwartz was above all these happenings and would not surrender to any depressing influences. His very look said that this incident of a church service for Ivan Ilych could not be a sufficient reason for infringing the order of the session — in other words, that it would certainly not prevent his unwrapping a new pack of cards and shuffling them that evening while a footman placed fresh candles on the table… Read more
Bridge Solver for Android smartphones
John Goacher has written the smartphone app that I wanted to develop in a world of infinite time. I’m glad someone did it and made it free too!
Bridge Solver is a double dummy solver that runs on Android smart phones. Within it you can navigate a web browser to a results page, for example one of the ACBLmerge unit game results, and click on the PBN link (near the top of the page) to save all the hands to the app. Then you can open any hand and explore the double dummy lines of play, much as you have long been able to do at a Windows desktop using the Bridgify software. For example, in the partial screenshot at the right, the subscripts on each card indicate the number of tricks that can be taken when the card is led. Green cards are optimal plays.
Like ACBLmerge and so many other programs, Bridge Solver relies on Bo Haglund’s double dummy solver (DDS) which in turn saw significant performance gains in 2014 as a result of improvements by Soren Hein. Good work, guys!
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.
Development of ACBLscore+ discontinued
Development of ACBLscore+ which was to replace the current ACBLscore program has been discontinued. Cessation of work was announced at the National Board of Directors open Q&A meeting at the summer NABC in Las Vegas. Read more.
December 30th revision: According to National BoD member Donald Mamula (D19), the technology motion was withdrawn by the maker of the motion, Rich DeMartino. Nonetheless, the motion did lead to a letter submitted to the BoD by 30 ACBL members, including unit president Matthew Kidd, with strong backgrounds in computer science, which may have directly influenced the announcement of a technology committee established by CEO Robert Hartman. Regrettably this committee reports to management rather than directly to the BoD, a situation that may dilute its effectiveness.
Balancing Statistics After One of a Suit
How many HCP is your side likely to have when you are in the balancing (pass out) seat after the auction has gone 1♣/1♦/1♥/1♠ – Pass – Pass to you? How does it change depending on how many points you hold? How many HCPs are opener, responder, and your partner likely to hold? What is the range of the range of possibilities?

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.

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.

The Mini-McKenney counts total masterpoints earned for the year and the Ace of Clubs counts only masterpoints earned at clubs as opposed to sectionals, regionals, and nationals. There are multiple brackets for each race based on the number of masterpoints a player has at the start of the year.

Unit News published in the Contract Bridge Forum is also available on our website. The Education & Resources page contains many links to rules and regulations, San Diego players, bidding and card play, online play, and even a bit of humor. The Free Bridge Software page has descriptions and links to some great free programs. The Analysis Projects page links to some in-depth analyses of bridge data, including the The Payoff Matrix.
