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.

Bridgeauszeichnungangst

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.

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, edged out 11-13 with one board member abstaining.

Payoff Matrices for the Esplanade Club games and for the Eastlake Bridge Club games are now available for every session using data from the entire 2013 calendar year.

San Diego unit game and combined La Jolla and San Diego unit game results for 2012-2013 were posted earlier.

Learn what has changed over the last six years. Read more.

Are you bidding enough slams?

Slams are not that rare. 13.6% of hands contain a slam in at least one seat. How well do strong partnerships bid slams and what types do they bid? Read more slam statistics.

*Revised January 11th at 8:30 pm: Board #1 had two errors: +430 was on the wrong side for Pottenger-Hartman vs Hastie-Herzog and +130 was on the wrong side for Oakley-Busby vs Kalish-Kalish. This change rearranges the top rankings.

*Revised again January 15th at 10 am: ACBLscore 7.89 has a bug which can cause Flt B masterpoint awards to be much lower than normal. After rescoring with the quickly released 7.90 update, three pairs who ranked only in Flt B went from very low awards (0.02 or 0.03 MP) to normal awards and four more pairs who ranked in multiple strats received a bigger award because their recomputed Flt B award was better than their award in the other strats (note: pairs receive the best award from all strats they are eligible to be ranked in–not the sum).

**Revised January 27th at 11 am: Board #4 Lane-Jelusich vs. Sauer-Byrne was corrected from +500 to +200. This does not change any rankings.

ACBLmerge and Bridge Results

Bridge Results Logo

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.

What’s New

Suicide King. 2014 President’s Awards. Lead Solver software is 40% faster and now runs on Mac OS X and Unix/Linux as well as Windows. ACBLgamedump utility. ACBLscore game file format (reverse engineered) documentation substantially updated.
