Report on 2018 Charter Oak Open


Abhijit Mondal, a grad student from UConn, won first place (3-0) at the 2018 Charter Oak Open Chess Championships.

Mondal (pronounced mon-dull) is from Bangladesh and is earning a Phd in Computer Science here on a F1 work visa.

Alex Woodbury and Eugene Bystrak tied for 2nd place, each with 2-1 scores.

Only eight players entered the tournament, mostly because the weather was sunny and warm after a miserable week of rain and cold.

We welcomed seven players new to our monthly tournament program. We are especially pleased to welcome our first new member who resides in the town of Coventry; Jacob Shor, age 15.

Jacob's father, Mike, is a professor of economics at UConn Storrs. Mike played dozens of informal games with many different opponents (including myself) throughout the day. Mike and Jacob helped put back the tables and chairs.

Eight benefited from our open house policy of free admission to spectators and those who play informal games.  This policy continues forward.  We have room to welcome anyone and everyone.  You can arrive at any time between 10am and 5pm.

I wish to thank everybody for being so considerate and helpful all day long.

NBCC 3rd Q Report by Bob Cyr

NEW BRITAIN CHESS CLUB

IN CARE OF THE ARMENIAN CHURCH OF THE HOLY RESURRECTION

1910 STANLEY STREET   NEW BRITAIN, CONNECTICUT

THIRD QUARTER 2018

HISTORICAL REPORT

“Your body has to be in top condition. Your chess deteriorates
as your body does. You can’t separate body from mind.”

Bobby Fischer

 

 

  • THE HIGHLIGHTS OF THE THIRD QUARTER

 

 

JULY

 

The club started its third quarter of 2018 with its 3rd annual July Knockout and Swiss event. The ideas for this relatively new tournament were created by FM Nelson Castaneda. Players were initially grouped into one section (knockout bracket). After each round, the winner would advance in the knockout bracket. In the case of a draw, a two-game blitz match would have to be played to determine the winner of the match. If the draw persisted after the blitz match, then the person who played with black in the classical game would advance. Anyone eliminated or knocked-out would be placed into an open Swiss-style event. Many of the games from this tournament were analyzed by Nelson and are published with his extensive notes on the club website. The final round was won by Expert Suhas Kodali, who knocked-out Nelson to claim the title of the 2018 NBCC Knockout Champion, his first win in a major club event. Also winning classical time-controlled events for their first time were two strong class players, Andrew Cowell and Mario Guevara-Rodriguez, who tied for first place in the Swiss section. Many thanks for Nelson for directing and analyzing many of the interesting games, some of which I imagine will be nominations for the best game of the year contest.

Prior to the start of Nelson’s event, our community was stunned to hear about the passing of James Wilkin. During the event, we also received tragic news about the passing of John Baclawski, another veteran member. Details on both of their memorial events and their eulogies are published later in this report.

 

AUGUST

To honor the memory of Jimi Wilkin, the club hosted the Jimi Wilkin Memorial Tournament on August 7. Before the event, Suhas Kodali did a wonderful job analyzing Jimi’s style of play by reviewing a number of his games. The NBCC was able to raise $700 to support Jimi’s family during their difficult time. Thirty-four players played in the event, with a pretty equal split in each section. In the rated section, FM Nelson Castaneda was the winner. In the more fun unrated gambit section, with the Albin Counter Gambit, the Wing Gambit, and early h4 moves, Ilya Goffman was the winner. Many thanks to Mark Bourque for directing and to Gert Hilhorst for collecting the entry fees.

In mid-August, the club continued its summer schedule by hosting a one-week event for Eric Hilhorst, the next member to be recognized for his longevity in our organization. Eric was introduced to the game at the young age of seven. Soon thereafter, he joined the club with his father, Gert, who has been a guiding force in his life. With his father as his coach and mentor, Eric quickly moved up the rating ladder. Today, Eric’s rating is around 1750. He has worked hard to attain this level and has aspirations to reach class A soon!

Beyond our family, Eric has competed in many regional and state tournaments, especially at the library chess club in his hometown in Simsbury, where he has won several events and developed many friendships. Eric, like his father, is one of our few members who has had the opportunity to play chess internationally. When he was fourteen years old, Eric competed on team leagues in Amsterdam. Incidentally, Eric has traveled to this beautiful city over seventy times with his father! Talk about earning frequent flying miles! All levity aside, when looking back at Eric’s chess history, his proudest achievement was earning the prestigious high school title at the 2015 Connecticut State Scholastic Championship and representing our state at the Denker Tournament in Arizona. Eric recently completed his freshman year at the University of Connecticut, where he is an active member and vice president of their chess club. Even though Eric has not been able to play chess as often as he would like to, due to his intensive academic workload, he does make an effort to compete in events at the UConn CC and the NBCC during school breaks.  Earlier this year, Eric had a blast participating on the grand stage at USATE for his first time with his fellow UConn teammates. Eric is truly an amazing young man and superstar, and he has so much passion and energy for life and a deep affection and compassion for people. My friends, our chess community is bright because of members like Eric. We are so thrilled to have Eric as part of our family, and we wish him the utmost best in his future chess and academic endeavors in his long life ahead. For his tournament, Eric proposed the Bilbao format, where each player played two games, one with the white pieces and one with the black pieces. Because of the format, the tournament could not be rated. Players were grouped into quads. The following players won their respective quad: Nelson Castaneda (Quad 1), Carter Clayton (Quad 2), Bill Campbell and Elizabeth Smith (Quad 3), and Norman Burtness and Joseph Hricko (Quad 4). Carter was presented with a trophy for the most unexpected result. Thanks to Gert for organizing and directing this exciting event.

Prior to Eric’s special event, FM Richard Bauer went over John Baclawski’s contribution to chess opening theory, examining his game from the 2008 NBCC Championship vs. Andres Castaneda. Mr. Bauer has plans to submit this game to Chess Life or to another popular chess magazine.

On August 21, Expert David Herscovici, our club’s newest lecturer, reviewed of some of his recent games, noting how high-rated players make decisions during critical parts of their games. We are most fortunate for David’s analysis and look forward to having him teach more lessons to our growing audience.

On a glorious and pleasant late-summer day (August 26) at Wickham Park in Manchester, sixty-four players from the area (the third-highest turnout for any event in NBCC history) gathered for spirited play and social interaction at the 53rd Summer Open. This year, the club broke a record for the most youths ages eighteen or younger competing in one of our events - 35! Many hours of work were performed on-site and behind the scenes to ensure the success of Connecticut's huge summer outing of the year. The following people did a fantastic job: Manager Gert Hilhorst, TD Jan van de Mortel, and Chef Mario Guevara-Rodriguez. The club also thanks to Rob Roy, NBCC’s loyal advocate, for bringing in ice-cold beverages and for being available to assist whenever needed and for advertising our event. Incidentally, the event winner on tie-breaks was FM Richard Bauer, who is now only one win or tie for a first place away in this event to tie Arkadijs Strazdins’ a record of ten. We hope to see you all next year! 

SEPTEMBER Every once in a while, a new event is held at the club. On the second week of the month, the club held its first Rated Rapid Showdown event. According to NBCC President Normal Burtness, “this new event is based on the chess.com Champions Showdown held last fall.” Players were paired to their nearest rival, and they had play ninety minutes of G/15; d/1, sixty minutes of G/5; d1, and fifteen minutes of G/1; d1. The winner was determined by a points system that awarded four points for each G/15 win, two points for every G/5 win, and one point for every G/1 win. The G/15 and G/5 games were rated but not the G/1 games. It was one wild evening of chess at the club that evening, and we thank Mr. Burtness for making this event possible. THE EVENT WINNERS OF THE THIRD QUARTER It was a very busy and fun third quarter for the club! Summer rules!

  • REMEMBERING JAMES “JIMI” WILKIN

 


It is with deep sadness to inform you about the sudden passing of James "Jimi" Wilkin, one of our club's veteran members. Jimi left his world on June 30, 2018, at the young age of forty-one. Jimi joined our family in 1998 and was a regular participant in many of our events for nearly two decades. Soon after joining the club, Jimi earned an expert rating of 2020. In chess, Jimi was particularly known for his unique opening repertoire and sharp tactical and positional play. He surely put an enormous amount of energy into his games. A few of Jimi's most memorable club achievements were winning the 2002 New Britain Summer Open Chess Championship and finishing in first place in the 2014 NBCC Championship Candidates Tournament, which automatically qualified him for the 2015 NBCC Championship. Jimi learned chess at an early age. In 1992, he won the high school division of the state championship and represented our state on a national level in Detroit later that year. He had such a passion, love, and enthusiasm for chess, and he treasured his friendships in the club. Jimi will be dearly missed by those who had the pleasure of knowing him. May he rest in eternal peace in heaven.

  • REMEMBERING JOHN BACLAWSKI

 



It is with a sad and heavy heart to inform you about the passing of one of our veteran members, John Baclawski. John left this world on July 24, 2018, after a very long and courageous battle with cancer. John’s history with our family spanned nearly fifty years. Widely known for his fighting and energetic spirit on the chess board, John appropriately earned the nickname - “The Claw.” In the annals of the club, John ranked in the top ten players in overall major (G/30 or longer) tournament victories, his first one earned in 1979 and his last one in 2010. Even though John preferred competing in the slower time-controlled events, he was always up for a quick or blitz game with his buddies. John was a friendly man who exhibited kindness to everyone in our community. May he rest in eternal peace in heaven.​ On July 29, a celebration of John’s life was held at the New Britain Quartette Club, where he was a member for many years.

The question is:

 

Who are the youngest members to win the 2018 New Britain Summer Open Chess Championship?

 

Unfortunately, no one answered my questions from the second quarter report. ☹



 

  • OTHER NEWS FROM THE NBCC HISTORICAL DEPARTMENT

 

 

In the coming weeks, we ask players to submit their best games for the annual NBCC Best Game of the Year contest. FM Richard Bauer reviews the games and awards the winners with cash and non-cash prizes. You can e-mail the games to Bob Cyr at doctork87@yahoo.com.

 

Other than that, I look forward to seeing you at the club and definitely at the Oktoberfest dinner party! Cheers! ☺

Chess Game in Florence Ends In 16 Moves

I didn’t seem to have the right length game for you this week so I am showing a short game and a long game in the hope they sort of average out. The human game is funny-ha ha and the computer game is funny-strange. We all know that you can’t force mate in the endgame when you only have two knights, but two knights is a force for mate in bughouse, and the winner of the recent 11th WMCA Free tournament finds a way for the two knights to end the game.
The computer game is from the never ending TCEC “computer championship” competition and should not to be played out unless you have a pgn reader, otherwise you might fall asleep. The first time the fifty move rule threatens to be invoked, White moves a pawn to pursue the positional space advantage. With the computer evaluations mysteriously reaching equality around move 184, they adversaries finally draw the game the second time the fifty move limit comes around. Considering that it’s almost a double fifty move rule game, there are an absurd number of pieces and pawns on the board at move one-ninety. The last 100 moves are just futile, the White king moves from f2 to f1, the White queen from b5 to d3 and the White rooks have moved from b1 and h3 to a1 and h1. The Black position has changed even less; astonishingly, the only difference in a hundred moves is that the Black queen has ventured from c7 to d7. Qd7 must be a very good move, because Black played it fourteen times. For those of you without pgn readers, the final position, on move 190, has the white king on f1, white queen on d3, rooks on h1 and a1 and pawns on a6, c4, d5, e4, f3, g4, and g3. The black pieces are the pawns on a7, b6, c5, e5, f6, g6, and h7; the rooks are on f8 and f7, the queen, of course, is on d7 and the king on g8.

CONNECTICUT CHESS MAGAZINE

 

Connecticut Chess Magazine and Coventry Chess Club are each philanthropic enterprises by Rob Roy.

They are not governmental initiatives nor are they business endeavors.

They are private initiatives by Rob Roy, for the public good, focusing on quality of life, and on chess in Connecticut.

They should never be misconstrued to represent the State of Connecticut, the Town of Coventry Connecticut, nor with any other chess associations.

The monthly tournaments in Coventry are conducted by Rob Roy acting as an independent organizer, and not by any chess club, state chapter, nor federation.

I have never written for, nor spoken for, anyone besides myself, Rob Roy, acting as an independent chess journalist.

Rob Roy derives no material gain from these two entities, in contrast; Rob Roy suffers significant monetary loss from their operations.

GAME OF THE WEEK

September 10, 2018 was a record day for chess geometry. At the World Junior Championships, there were two games with totally closed full files on the board after 24 moves. I had never seen them exist later than the opening. In the strange sort of coincidence that long-time readers have come to expect on this page, on the same day at the same tournament, there was also a game with a rare, full rank. All three games are below.

NOV 3 = 2018 MEMBERSHIP MEETING STATE CHESS ASSOC.

 
Derek Mansfield, acting president, has scheduled the ANNUAL MEMBERSHIP MEETING of the Connecticut State Chess Association (CSCA) :  It will be held on Saturday November 3, 2018  from 2pm to 4pm at the Meriden Public Library, 105 Miller Street, Meriden, CT 06450.
 
Please forward notice of this meeting to anyone you think may be interested in attending. Membership to the CSCA costs $5/year (usually paid with entry to tournaments awarding a Connecticut state title).  
 
The membership will elect individuals to fill all of the open seats on the board of directors.  The board of directors will then vote on which organizers (from the bids submitted) who will conduct the various state championships for 2019.
 
Former directors Rob Roy (also 10 time president) and myself are currently running to serve on the board of directors.  There are at least four other seats open on the CSCA board of directors.  
 
To clarify;  NO NEED TO BE A TOURNAMENT DIRECTOR to serve on the CSCA board of directors.  I am hoping for a good turn out and good progress towards resolving some of the issues we have been having.
 
Thanks,
 
Rick Bauer

 

P.S. Free kid tournament at Noon

CONNECTICUT CHESS MAGAZINE

 

Connecticut Chess Magazine and Coventry Chess Club are each philanthropic enterprises by Rob Roy.

They are not governmental initiatives nor are they business endeavors.

They are private initiatives by Rob Roy, for the public good, focusing on quality of life, and on chess in Connecticut.

They should never be misconstrued to represent the State of Connecticut, the Town of Coventry Connecticut, nor with any other chess associations.

The monthly tournaments in Coventry are conducted by Rob Roy acting as an independent organizer, and not by any chess club, state chapter, nor federation.

I have never written for, nor spoken for, anyone besides myself, Rob Roy, acting as an independent chess journalist.

Rob Roy derives no material gain from these two entities, in contrast; Rob Roy suffers significant monetary loss from their operations.
