The ACBL Online Partnership Desk

STaC week is winding down with almost all events and finals results posted. Tournament players are setting their sights onto the Fall 2019 NABC from Nov 28 – Dec 8, and after that the Big Apple Winter Regional from Dec 26 to Dec 30.

For those scrambling last minute plans (possibly your partner’s fault), did you know there is an ACBL Online Partnership desk? Dozens of players are waiting online to be contacted for partners and teammates, and the online partnership desk provides more information than the typical low tech bulletin board of index cards.

When searching through a perspective “bridge date”, you can see their preferred bidding system (ACOL, 2/1, Precision, Polish Club). You can see both the Masterpoints they have AND the exactly color pigment breakdown, plus any Red, Blue, and Silver ribbon qualifiers. You also know the date they joined ACBL and their city, state, if you find that useful.

Last year for Honolulu, the online desk landed me a wonderful partner who lived in neighboring Long Island, and we continued to play together at the NYC Regional this year!

Free ACBL Practice Tournament vs Advanced Bots Today

Today is the last free practice ACBL tournament before the Fall 2019 NABC Robot Individual tournament. Log in and go to ACBL World to find it, NOT Robot world, even though both worlds are full of robots.

Go to ACBL World from the BBO main page, then find the only tournament that says “Free” on the entry. You will need a BBO account linked with an active ACBL number to play.

Normally you need to pay $1 per day to rent an advanced bot on BBO, or $1.35 per day to play a 12 board tournament against advanced bots. They are stronger than the basic bots, which are only $1 per week to rent, or free when you challenge a friend. A few lucky and skillful winners in the practice tournament will earn a free entry to the Online Individual, a $40 value (or $34 if you are a repeat customer returning competitor).

According to the CEO of BridgeBase, basic bots perform better than about 90% of human players in the daily daylong tournaments, and advanced bots perform better than 97% of human players. Log in and give it a shot!

Swiss Teams with Hand Records!

What are some of the reasons to play team games instead of pairs?

  • Team games usually use IMP scoring. Emphasis is on making the contract instead of agonizing over every little overtrick
  • You actually use the crazy safety plays from BBO’s free Bridge Master lessons
  • Team games are the easiest way to earn gold points and ribbon qualifiers at the upcoming Big Apple Winter Regional (Dec 26 – Dec 30 2019)

One of the most annoying drawbacks of team games is the lack of hand records. Perhaps that’s actually better for morale, but for those who love to post-mortem, you only have what you remember. Even at nationals, team games are usually shuffle-and-play, with a network of caddies to bring boards back and forth between your tables.

The Honors Swiss game is one of the few places to use pre-duplicated boards while regularly hosting over 20 tables of Swiss teams. The directors expend great effort to create multiple sets of boards and design a complex rotation to make it all work. At the end you receive hand records in print and online. Unfortunately, teams report match scores but not the results on each board. If there is an interesting hand, you only learn how you and your teammates played it, not the usual dozen results following a pairs game.

In IMP scoring, making the contract is the most important goal. You might not take the “safety play” in matchpoints, especially when an alternative is very likely to win overtricks.

Know of any other clubs with team games that provide hand-records? The only other club where I have seen pre-duplicated Swiss teams on a regular basis is the Yotsuya Bridge Center in Tokyo, Japan.

Masterpoint Races and GNYBA

ACBL has the standard Mini McKenney and Ace of Clubs masterpoint races for each unit and district, with overall leaderboards for the entire continent of North America. It’s that time of year to check your standings in the Unit 155 Masterpoint Races.

Ace of Clubs counts the annual points won at any ACBL sanctioned physical club game (excludes online points). Mini-McKenney counts all ACBL sanctioned events, including tournaments. The $40 robot online individual hosted on BBO is an NABC event paying red and gold points, which DOES count, but not other BBO ACBL events.

Here in Greater New York, we have our own special race – the GNYBA Player of the Year Award. The bulk of the formula is tied to specific major events such as Goldman Pairs, NAP, GNT, and other tournaments deemed prestigious by tradition. Of course, luck plays a part in all events, but the award hopes to focus on consistent high scores playing in a strong field.

There are three categories with different formulas: individuals, individuals playing team games, and Flight B players. Here are the YTD standings:

Result Stalking: STaC Week Edition

First off, let’s admit we are all guilty of result stalking to some degree. When the club or Common Game results are delayed only half a day, people get antsy. What’s going on? Was there some massive scoring mistake? Did they realize we played the wrong boards? Don’t worry, you aren’t the only one refreshing your browser.

STaC week adds a second layer of result stalking – first you can see the club results, but there is a STaC delay before you can see the final silver point payouts with STaC bonus. The day after email is one way to find it, but if you did not play the event, you will need to find the Fall 2019, Unit 155 STaC results.

Even though it is currently Wednesday afternoon, we know results are delayed about 1-2 days. The only available result right now is the Monday afternoon session. Here are the results! Well done Marc and Cathy Nathan for their 69.35% game at Aces Bridge Club!

For those who didn’t dive into the inner mechanics of the STaC bonus formula, it is a simple calculation for open pairs, single-session public club events: 1.875 + 0.1875*Number_of_Tables. With 49.5 tables, it seems they round down.

1.875 + 0.1875 * 49 = 11.06 Silver

William Sigward and Jack Hartog won first place in strat B with a 69.05% game. However, 2nd place in A paid significantly more, which is 75% of the first prize (so you ignore any B-strat prize). Raymond Leon and Louis Haber took 2nd in B, with a solid 63.99% game. We can use their reward to deduce the number of B and C players among the 49.5 tables! However, I leave that as an exercise to the reader.

Happy STaCing for those playing later this week. For the rest, keep refreshing…

ACBL Item 193-63 Discussion

District 24 member Leon Yu (left), with his teammates Xuhua Lin, Tsao-Tung Tsai, and Jim Liu, winners of the Summer 2018 NABC 0-2500 Spingold teams.

Yesterday’s post discussed an ACBL motion to move the Bean Red Ribbon Pairs to Spring NABC, specifically the first weekend. Item 193-63 adds a new 0-3000 Swiss game in the middle of the week, and NAP flights B and C will likely be held on the 2nd weekend. If both motions pass, there will be a clear roadmap of NABC events for flight B/C players staying 9 days.

A few questions to ask:

  • Why 0-3000 teams instead of 0-2500? Red Ribbon, Sally Young, and Micro-Spingold are all 0-2500, as are the GNT and NAP Flight B cutoffs.
  • NAP finalists should be in a Matchpoints mindset (and practicing conventions and bidding with Matchpoints in mind). Would the 200 Flight B and C NAP district finalist pairs join the 0-3000 teams, or will they prefer pairs events as a final practice?
  • Will Red Ribbon pairs become a 6-session event instead of 4-session event? The Blue Ribbon and Mini-Blue Ribbon events are both 6-session, as are the Sally Young 0-2500 pairs during summer NABC.
  • With more and more events targeted at “competitive intermediate” players, will future NABCs include a Nano-Spingold and Mini-Red ribbon, for 0-500 players?
  • Will all the limited NABC events dilute the playing pool for the daily Gold Rush, Open Pair, and Team events (the regionally rated events)?

Voting on ACBL Item 193-62

Chris Moh, Jacqueline Chang, Siqing Yu, and Jordan Lampe, all GNYBA Unit 155 Members and winners of the 0-2500 Mini-Spingold 2019 in Las Vegas NABC.

The ACBL Board of Directors meeting at San Francisco will discuss and vote on a number of items relating to restructuring the board, handling disciplinary proceedings, financial matters, and tournament modifications.

Today we discuss the pros and cons of Item 193-62, which impacts every player with an unspent Red Ribbon qualifier. If you’ve played enough Gold Rush or low bracket team games during regionals, you most likely have plenty of ribbon qualifiers.

Item 193-62 proposes to move the Red Ribbon pairs event 
from the current time at the end of the Summer NABC 
to the first weekend of the Spring NABC.

Of the 3 annual NABCs, Summer is most popular among younger players, both in age and experience. Limited NABC events include GNT Flights B and C, the Sally Young 0-2500 Pairs, Micro-Spingold 0-2500, and Red Ribbon Pairs. Youth NABC and Collegiate Bowl are also held during the second week. That’s a lot of excellent multi-day intermediate games!

Unfortunately, the heavy concentration of events overlap! A team playing in GNT can only play in the 0-2500 Pairs if they are eliminated in the first two days. Similarly, all mini-Spingold teams in the quarter-finals are not be able to enter Red Ribbon. Strong players from Youth NABC and Collegiate Bowl must miss both events! For two years in a row, District 24 players won the 0-2500 Spingold (pictured above), opting out of Red Ribbon. Many others planned their playing itineraries knowing they could only choose one.

Spring NABC, on the other hand, is considered the serious NABC. It hosts the prestigious Norman Kay Platinum Pairs, and has no limited events designed for Flight B players other than NAP (Flights B and C). Each of 25 ACBL districts send four pairs in EACH of Flights B and C, a total of 400 potential eligible players for 0-2500 events. With NAP on the last weekend of the tournament, is Gold Rush or Silidor Open Pairs the better practice? That’s a good segue into Item 193-63.

Item 193-63 proposes to add a new 4-session, 
Swiss Team 0-3000 event in the middle of Spring NABC.

Every NABC consists of several nationally rated NABC events, most lasting 2-3 days each, that award NABC titles to the winner. In parallel, there are standalone, generic events: the daily Gold Rush pairs, Open Pairs, and team events. They operate more like a regional. Winning does not confer a title, but you get 2 minutes of fame in the next day’s daily bulletin and a trinket if you remember to swing by the prize desk.

The key question is whether NABCs should hold more nationally rated events for intermediate players. Will it entice players on the fence to come to NABC? Does it dilute the prestige of an NABC title? Should we keep the serious Spring NABC and the more newcomer friendly Summer NABC? What effects will it have on the parallel regional events? We shall discuss in depth next time!

STaC Week Fall 2019: When and Where

Today, the most brave and devout among us are in Allendale getting their silver, or getting online Masterpoints in the free BBO Bot Practice Round, both topics for another day. For the rest of us, the final STaC week of the 2019 begins tomorrow (Edit: there is a mini-STaC just before Xmas, but only for 3 days).

Yesterday’s post discussed the Masterpoint benefits of STaC week. Instead of math and formulas, today we stick to the more practical question of where and when to actually go and play!

            6:00 pm  Honors Swiss Teams (RSVP needed)

There are also invitational STaC sessions at various private clubs – if you haven’t played at those clubs during the regular sessions, then it would be unseemly to barge your way in just for STaC week!

Nerding Out with STaC Math and Silver Points

Next week is New York City’s last STaC week of 2019! Most of us have friends who invite us to play in Woodbridge or Allendale every few months. Most of us politely decline. Why cross rivers and state lines when you can earn silver in the comfort of your own club?

We all love our local Sectional Tournaments at the Clubs. They award those elusive silver pigmented Masterpoints, but they also pay a mysterious STaC bonus. You know what I’m talking about – the lovely email you receive the next day titled “Your STaC Results are Ready”.

What exactly IS the bonus? Some clubs say it is double points, some say triple points. Turns out they are all wrong! The official formula from ACBL looks daunting. Here is part of it below:

Thankfully, almost all open, single-session pair games during STaC week simplify into one nice and neat formula with only one variable, the table count:

STaC Pairs First Place: 1.875 + 0.1875 * Number_of_tables

For those playing in a single session swiss instead of pairs, you get a bit less per table, because you aren’t competing against as many teams per table, so it is easier to win.

STaC Swiss First Place: 1.50 + 0.15 * Number_of_tables

What if you are playing a 0-750 game? Then you multiply by the Gold Rush multiple, which is 52.5%. Somewhere along the way, someone at ACBL decided that seemed fair.

Let’s use STaC results from the summer as an example. Monday Afternoon June 3, 2019, the Cavendish Results suggest that the winning pair earned 1.78 masterpoints (well done David Gurvich and Rica Tarnoff with a 69.35% game).

http://clubresults.acbl.org/Results/227306/2019/06/190603A.HTM

However, the winners waited in suspense for that “next day email” to deliver the good news. The STaC combines sections and tables from other NYC clubs such as Aces, Pride of Judea, and Sephardic; bringing the total table count to 60. First place overall becomes:

1.875 + 0.1875 * 60 = 13.13 Silver Points

Not a bad haul for 24 boards at the club! Second place got 75% of first, third place gets 75% of second, and so on. Lower strats are slightly more complex, but we’ve seen enough formulas for one day. Good luck everyone this upcoming STaC!
