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.

Card fees increasing to $9
The board voted in November to raise the card fees to $9 effective November 23, 2014. This fee increase is primarily the result of declining table counts. As recently as FY 2010-2011, the average table count was almost exactly 20. There was a notable drop in FY 2011-2012 to 17.6 and another significant drop in FY 2013-2014 to 15.7. Although some of the game expenses scale with the number of players, others such as rent, the caddy, janitorial service mandated by our lease, and insurance, do not.
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.
November 28th update: National BoD passes a modified version of the technology motion, hopefully urged on by a letter submitted to the BoD by 30 ACBL members, including unit president Matthew Kidd, with strong backgrounds in computer science.
Suzi Subeck (D13) will be the 2015 ACBL President
Suzi Subeck of District 13 will be the 2015 ACBL President. Our D22 national representative, Ken Monzingo, had also sought this position.
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? See the simulation results.
Masterpoint formula changes proposed for 2015
The ACBL Masterpoint Committee has unanimously voted on a set of changes to how masterpoints are calculated at tournaments and for special club games that are based on some fraction of the sectional rating. The changes will go into effect on January 1, 2015 if the National Board of Directors approves the changes at their fall meeting at the NABC in Providence, RI. Read more. November 28th update: Approved at Providence meeting.
Notes from Kantar’s Modern Bridge Defense books
Now and then, it’s good to review things you may have forgotten, never really learned, or which slowly evolve. I wrote up some notes after quickly reading Kantar’s two volume set Eddie Kantar Teaches Modern Bridge Defense and Eddie Kantar Teaches Advanced Bridge Defense, both published in 1999.

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.
