Ray’s Instant Replays: Cracking The Re-Whip in San Jose

Instant replays enhance sports viewing immeasurably. They are also now used to determine the right call by game officials at crucial moments of a contest. I think I can expand my horizons a little here and apply that concept to Backgammon Tournaments. Smart phones, live streaming, and recording stations proliferate the scene nowadays. As a result, specific plays can be highlighted and discussed. This will be my purpose here.

With such an endless supply of material available to us the USBGF wants to be on the leading edge of the backgammon information age with this blog. April Kennedy is a talented promoter and has become the Social Media Director for the USBGF, under the direction and influence of Karen Davis. They approached me with this idea as I have written a few articles for Prime Time magazine and have the most experience playing on the American Backgammon Tour over the last 25 years. Writing comes easily to me but I have never done a blog except to post occasionally at Stick Rice’s BG Online which remains a great source of real time backgammon information. I envision a process where I can log on and share pertinent positions, ideas and problems I have recently encountered over the board. Perhaps even between matches at a tournament. Maybe there will be an opportunity for Questions and Answers too.
As one of the most active players on the ABT, I can serve as your guide through the many maze like situations you will face playing matches. I might be able to bring obscure concepts into clearer focus for you or shine a light on those that you were not aware of. The possibilities are intriguing to me and I hope to gain knowledge and understanding myself while sharing it with you. We can all learn together and maybe a certain synergy will develop in the process.

The upcoming fall issue of Prime Time magazine highlights the return to backgammon of the great Art Benjamin. I think the American Backgammon Tour is in its 25th year and not many people know that Art was once the leader of the ABT for the first five years or so before he took a leave of absence to start his family and pursue his career as a math professor. It occurs to me that all of the current and former number one players on the ABT are now working closely with the USBGF in some capacity. Marty Storer, Art, and Neil Kazaross are current board mebers, for instance. I write freelance and will be the Captain for the maiden voyage of this blog.

So, let’s bust a bottle of champagne on the bow, and christen the SS INSTANT REPLAY shall we?

People like stories and I like telling them so here we go. Once upon a time, in the year 2018, I journeyed to San Jose… Intent upon playing in the Silicon Valley Open backgammon tournament run by Ken Bame and his staff. Ken runs a Swiss movement tournament and was ably assisted by Jeb Horton, a sort of travelling expert on Backgammon Tournaments. Ken and Jeb worked hard all weekend to get the job done but they were plagued by some inevitable slow play, as usual for most backgammon tournaments even though the use of play clocks has become widely accepted.

Regardless I was enjoying some good fortune in the event having won my first four matches. At that point there were three players left undefeated: Myself, Art Benjamin and the ever present Jack Edelson from Wisconsin. The draw was posted for round five, and Jack was going to play Art, then something went haywire and I noticed that I was paired against a player whose record was 2-2. Winners play winners in this format, so that would not do. The draw was redone and now I was to face Art and our match was designated to be streamed live.

Not wanting to embarrass Art who would soon be featured in Prime Time magazine, I let him win our match 9-2/9. Few players possess the innate sensitivity to work with a story line as I do (smile). Art sent me to bed with a respectable 4 and 1 record. Jack won his match so Jack and Art would go up the hill to fetch a pail of ABT points the next day. Jack fell down and lost his crown and Art remained undefeated. The leader board was taking form by now.

I had lost to Art and the next two players I played on day two. Having reached round eight, even Art had now lost a match to Chris Knapp, a player from Canada. Evidently Chris had a different idea for the ending of this story! As it happens Chris and Art played two more times in this event… The second of which spawned the subject of this article. I was watching them play and Art was leading 2-1/9. Art owned the cube on 2 and they were in a bear off. Art rolled a fortunate set and the position became this:

I thought idly that Art should redouble Chris and Chris would take it and this game would weigh heavily in the outcome of this relatively short match. Then Art fooled me! He began thinking and staring at the board. His hands were held at an awkward angle and his head was cocked to the side. It bounced a little as bits of information struggled to take center stage in his conscious thought process.
Art ciphers quicker than most so I didn’t have to wait long for his decision. He rolled the dice without redoubling. Both he and Chris, at his turn, rolled non doublets and then Art redoubled and Chris passed. The score was changed to 4-1/9 in Art’s favor. I took my leave at that point and resolved to revisit the situation with Art later. Meanwhile another great player and one of the fastest ever on the American Backgammon Tour walked by. Frank Talbot, another member of the USBGF Board of Directors. Frank likes to talk backgammon so I showed him the position too. Frank quickly recognized that double ones and double twos did not “work” for Art, and after some careful consideration Frank said: This is a hold, and he mentioned the score being a factor. That means no redouble in BG lingo, for the uninitiated.
In hindsight we can all see that Art and Frank have erred on the side of caution, while I would have carelessly re whipped a 4 cube over. Interestingly enough Art took second to Chris in the tournament, and Frank also cashed, while I did not. Frank’s feat was all the more impressive when you consider that he was 2 wins and 3 losses after five matches, necessitating that he win at least six matches in a row to cash. I was glad he proposed to call off our side bet in the money round after I lost it, lol.

I think we can learn something here given these circumstances. In general it may well be better to err on the side of caution than to have an itchy redoubling finger. Wild West gunfighters may not have been too adept at backgammon because somebody is likely to take you out with one lucky shot if you get into a lot of gunfights.

Fortunately after writing this article I got a call from Art, who was more than happy to have his match play boo boo shared with you. Art is secure in his masculinity and does not fret about showing he is human after all. In fact, the math professor in him explained to me the lesson that can be learned from this exercise. I think we all agree that though XG has a definitive idea about the line of play here, those lines get distorted in the human v human experience.

Let’s pick Art’s brain as I paraphrase what he told me before and after the XG analysis.
At the tournament Art was well prepared for my question which was why didn’t he redouble in the four roll position. He told me that he had memorized all the take points of 4 cubes in 9 point matches (!). Needless to say, I haven’t. He therefore knew that Chris Knapp had a take in a three roll position and so he could not lose his market in the four roll position unless he rolled a working doublet, thank you very much. I was playing for money on the side when he explained this and my opponent put the three roll position into XG mobile which said Chris should pass. I told him I would trust Arts math over XG mobile because Art has published more math and done more seminars than his smart phone. Then I lost thirty points to Stepan Nuniyants son Vadim. Get the picture???

After I had time to enter the position into XG and learn the bottom line, Art called me on the phone.
He explained that his chart (he has a chart?) noted that assuming 80% cube efficiency, the trailer’s take point at the score of 2-1 to 9 goes all the way down to 19%. Loosely translated that means because of potential future cube leverage you can take more freely at this relatively innocuous sore than usual. For example, the leader will need 30% game winning chances take an 8-cube if the game turns around.
In general terms, this would coincide with match play conventional wisdom. Leaders should protect their lead while trailers can become more aggressive.

The problem here, according to Art, was that, in retrospect, Chris does not have nearly enough cube efficiency. Efficiency is what Art called it and it was difficult for him to describe to me because he says it is complicated to ascertain. Enough said, Art! To try and explain the concept in layman’s terms, let’s think of cube efficiency as a function of time. In a holding game or long race the trailer would have sufficient time to find a good spot to effectively use the cube leverage the leader was handing him. Got it?
Here, in this four roll hybrid, the one thing we have little of is time! The dice will weigh heavily in the outcome and Chris must LOSE HIS MARKET by a mile to win. He won’t be able to get in any cute little 8 cubes on the come. Are you following me? If Chris rolls doubles to get an advantage, his winning chances won’t be 70%, they’ll be closer to 85%. His 8-cube would be very inefficient.

Anyway, due to this lack of cube efficiency Art said that Chris’ take point reverts back to the normal area of 25%. This makes holding back on the redouble a definite error, and the three roll position a blunder to take!

I guess Art will be revising those charts. Frank will become more deadly accurate OTB. I will remain confused. This game is hard, man.

In closing I will say that it is great to have Art back. He has a way of simplifying difficult problems and passing them on to us. He gave a seminar at this tournament and the last and I believe he will revolutionize the game and the way we think about it in the near future. Second place was a fine showing of his talent(s).

Congratulations Chris Knapp on winning your fourth ABT championship in recent years. If you can beat Art two out of three matches, you deserve it!

One of the best kept secret USBGF Membership Benefits is the OLM (OnLine Match), as described by OLM Moderator Jason Lee:

I’m the moderator of the USBGF OLM, which has been in action since 2012.  The USBGF Members play a match against Neil Kazaross, at the pace of one move per day.  There is a vote each day on the move to make.  Think of the OLM as a giant consulting match — Neil Kazaross vs. the collective mind of the USBGF Members.

I have an email mailing list where people can get an update when a new position is posted for voting.  I try to put up a new position every day — occasionally days slip by without a vote, but lately I’ve been pretty on top of it.

One does not need to be on the mailing list to vote.  To vote, you could just go to the USBGF site, and look in the middle under “What’s New” — you can see a link that says “USBGF OLM” and then a date.  If you click on that, it brings you to the most recent posting.  Each posting will give the previous day’s position, a rollout, and the voting results.  Then I have expert commentary, currently written by Grant Hoffman and Steve Sax (formerly by Marty Storer and Mary Hickey).  After that, Neil has his position that he has to play, and gives his commentary.  Finally at the bottom, there’s a position to vote on, with a box to type in your move.  One must be a USBGF Member and be logged into the site with their USBGF credentials to vote.  I receive all the votes, tabulate them, and the move with the most votes is what is actually played by the USBGF Members.  I tabulate the results, get the commentary from my expert panel, get Neil’s move and commentary, and start all over again.

When I make the post each day, I send out that email to inform people that there is a new vote in the offing.

On each day’s posting, there is a place at the bottom where people can comment on the play, offering their opinions and generally discussing the move at hand.

On average, about 30 people vote each day.  The mailing list currently numbers around 80… not everybody participates every single day.

I think the OLM has value to players of all skill level.  There are a number of of Open level players who participate regularly, along with plenty of Intermediate and Beginners.  I think the skill level of the participating players varies widely.  In spite of that diversity of skill level, the USBGF Members, as a collective mind, play at a World Class level.
