NBCC MARKS ANNIVERSARY

Greetings, friends and friends of the New Britain Chess Club:

I am elated to inform you that this Friday, January 26, will mark the anniversary of the most important day in the history of the NBCC.

It was 117 years ago, on Saturday, January 26, 1901, when thirty-three people, led by John Kirkham, met in downtown New Britain to lay the foundations for the official birth of what would eventually become one of the largest, historic, and finest chess organizations in Connecticut.

The NBCC has been blessed to be where it is today because of our loyal supporters and devoted leaders. Many chess clubs come and go, but the NBCC has continued to exist because of this.

It has been a joy of a lifetime to be responsible for preserving, publishing, and promoting the heritage of our rich, diverse, and ever-growing chess community. I take pride in what I do and hope to continue to carry out my duties as NBCC historian for as long as possible. Whenever I visit my non-chess family and friends, I always talk very highly about our club and its people and how they have truly enriched my life.

I welcome you to visit the website that tells the story of US - the New Britain Chess Club - "The Heart of Connecticut Chess" - that I wrote a few years ago (and will update in the coming decades - yes, decades!)

http://www.chessct.org/nbcc/nbccmenuitem.php?lm=nbcchist.lm&caller=nbcchist&text=Story

Thank you for being a part of this wonderful, thriving community. Thank you for your friendship.

With warmest regards,

Bob Cyr

NBCC Historian

Magazine a New Force for Chess in Connecticut

The new website for Connecticut Chess Magazine began in May 2010.

Starting out with zero-readership and then averaging 100 visitors per month by 2013.

A one-time print edition, costing $500, was sent to hundreds of Conn USCF players gave us the boost we needed.

From 2013 thru 2016 CCM averaged 1,500 visitors per month.

In 2016 we spent another $600 in advertising to reach out to new readers in Connecticut.

During 2017 Rob has gotten newspaper reports of our tournaments published in the New London Day, in the Norwich Bulletin, and twice in the Hartford Courant.

Connecticut Chess Magazine has averaged 3,000 visitors per month now for more than a year.

We are now the official state chess publication for Connecticut.

Our mission is to provide our readers with quality chess content, free promotion for chess events in Connecticut, and free reporting of the results, with games and photos.

You can help us with our current membership drive by forwarding this edition to your friends.

Our mailing list is confidential and is not shared with anyone. FeedBurner manages the membership database; you control Subscribe and Un-Subscribe.

Alan Lasser's Game of the Week

A year ago I attempted to add real statistical fuel to the ancient argument of which piece is better, the bishop or the knight. This year I have repeated the project to expand and improve it. The weakness of my study is that my random database is the almost 500 games that have appeared in GOTW, an insignificant number compared to the data base of several million master games.

Last year's results left questions unanswered. You have to exchange at least a pair of bishops to reach most endings, so the BXB move might average about once a game. Other than themselves, who were the bishops really slaying? Could the bishops be busy sniping pawns while the knights were more likely to be part of major combinations? My previous study also neglected to tabulate the most important number; which piece, the bishop or the knight, made the final move of the game, the move that convinced the opponent to resign.

In this issue I present the new expanded study, but unfortunately my statistics are already slightly skewed. I frequently play the Bad Opening, where you can get three pieces for the queen in several variations; my long-term readers have seen sixteen of my games, as well as similar exchanges by computers and grandmasters. Most players might see the three pieces for the queen once or twice a career, but there are enough of my own games included in my "random sample" for the numbers to be a bit unreal. I decided to make an adjustment to this year’s study, in order to bring the numbers of BXQ down a bit, I removed nine of these games that had been in last year’s study. After my adjustment, the knights captured 66 queens, the bishops 53; and you could still argue that I should have made a bigger adjustment to the raw sample.

So here are the results, in the sample of 497 games previously appearing in GOTW, the bishops ruled once again, making a total of 1367 captures while the knights managed only 1255; the knights averaged 2.53 captures a game to the bishop’s 2.75. The bishops were better at capturing rooks, knights, and bishops, the knights were better at capturing queens and pawns. 42% of all the knight captures were pawns, 31% of the bishop captures were pawns. If you add all the captured points together(3261 for knights, 3732 for bishops), the knights take 6.56 points a game while the bishops slay 7.51. If you look at the numbers per capture, the results are closer; the knights averaged 2.60 points per capture while each bishop capture netted 2.73 points. There was one surprising revelation in my study; in the 497 games, a bishop captured a bishop 339 times and a knight captured a knight 339 times. I wonder what that means. Finally and most importantly, the moves causing resignation or delivering mate clearly favored the knight, 44 to 38. Perhaps the argument can now be framed differently; would you rather have the piece that captures the most points, or the piece that takes the most queens and kings? Until a bigger study comes along, you can quote me.

It was very complicated when the center dissolved and Black’s fate depended upon defending against the two passed center pawns. Then White found 28.Rd7.
