Chess Game of the Week by Alan Lasser

 Congratulations to Sam Shankland, the surprise new US Chess Champion, who won the competition ahead of three “super-GMs”.  He racked up the decisive points against the lowest rated players and held off the big three in their individual match-ups.  In what was really a must-win game for him at that point in the tournament, Nakamura went with 1.b3 and got nowhere.

Report - Connecticut State Chess Meeting - April 28

 
 
Hi Rob,
 
You may post the following notes to the recent meeting on your blog.  
 
Please note that I have been honored to have been a contributor to the CSCA for the last 25 or so years.  I got involved because I was grateful to be in a state where I had a chance to win a state title and to the people who made that opportunity possible.  I never did anything to increase my chances of winning a title or to profit financially.
 
I had the honor of working with Frank Camaratta, Rob Roy, Michael Stango, Fred Townsend and Jim Celone as presidents and numerous other contributors.  It is now a good time for me to step aside and make room for younger and fresher faces.  But I think you will agree that I do not intend to "go quietly."  I clearly spoke more at this last meeting than I did in any previous one.
 
--------------------------------------------------
 
A meeting was held on April 28, 2018 at the West Haven Police Department.
 
Time will tell whether or not it will stand as an official meeting of the CSCA.  It was the third, and hopefully last in a series of disputed meetings of the CSCA.  
 
A quorum was declared on the basis that the Oct 1 meeting was invalid due to lack of a quorum.  This despite the ruling of the chair that a quorum had been achieved on Oct 1.  
 
I objected to the meeting on this basis and Jim promised to distribute his legal expert opinion as to the invalidation of the Oct 1 meeting.
 
I also objected to the meeting on the basis that many directors and members of the CSCA could not attend due to the conflict with the Eastern Class Championships in Sturbridge. 
 
When Bob Milardo arrived, a quorum was declared, consisting of several directors whose terms had lapsed and one on the phone (who had prevoisly resigned?).
 
There was a very impressive turnout, however, including both long time members and newly minted ones ($5 at the door).
 
Jim Celone chaired the meeting and Bob Milardo acted as parlimentarian.
 
Old directors were reinstated and two(?) new ones were added:  Derek Mansfield and Al Pinto.  Both are long time players and real contributors to chess. 
 
Jim Celone, Bob Milardo, Bruce Swan and Richard Chang were reinstated as directors. 
 
Officers were elected and Jim was elected president.  He then compiled a slate of the other officers to be moved.  I don't remember everyone (CJ?) but do know that Bob Milardo was elected Treasurer and CJ, Secretary.  Scholastic Grants and Ombudsman remain open (volunteers?).  Jim nominated me and then Rich Jackson for Ombudsman, but we both declined.
 
After the election of directors, the meeting went into (semi) closed session where non directors were allowed to observe but not participate.  Disciplinary action toward members was discussed.  Prior to this I suggested that this may not be in the interest of a true statewide organization.
 
The damage caused by the Lumelski lawsuit was detailed and Alex Lumelski was Censored.  The decision of punishment was deferred.
 
Jim asked the board to also censor Gert Hillhorst for "stealing" the website.  I felt compelled to add (since I had not heard it mentioned) that Gert had designed the website and was generously praised by Jim at the time.  Jim responded that there is a logo he designed that he would like removed from the alternate website.  Our exchange was then ruled out of order for the closed session.
 
Nevertheless, Bob Millardo argued against Gert's censure and it was dropped.
 
I don't know of any other business discussed, but will await CJ's official report.
 
While I do object to this meeting based on timing, difficulty determining the board, methods of notification, etc., it was nice to see so many old and new faces in a room to discuss chess in Connecticut.
 
Good Luck,
 
Rick Bauer

Chess Game of the Week, by Alan Lasser

It’s probably happened hundreds of times;  well-meaning, devoted parents are taken in by that old canard, “chess makes you smarter”.  Science does not support that, any brain activity is good for children, solving jigsaw puzzles would be just as neurologically stimulating.  
But the pressure to be a good parent and make your kid smart results in chess classes for four and five year olds.  Unfortunately, it’s only natural for children to hate anything that their parents make them do, so as soon as they have the chance, they abandon our game.  Every once in a while, after they grow up, they stop by their college chess club to make a few moves, just to see if they are any good.
Thus began the legend of Yixin Li.  The nineteen year old has the potential to be a titled player, but he only played in one tournament, where he landed a 2461 rating and had his name engraved on that huge rotating trophy for the Western Massachusetts/Pioneer Valley Champion.
He’s returning to China for the summer break and is unsure if he will be back to attend UMass next semester.  He says it’s possible that he’ll never play tournament chess again.  His all too brief career has been a mere 22 recorded games, including the five at the tournament and thirteen against me.  This is the last one.

Suhas Kodali - Jithu Sajeevan 2018 Nathan Hale Co-Champions

 This game could be some kind of a record-breaker, there are seven rook’s pawns.  At some point in the game each player has six isolated pawns, and there is a portion of the game where all eleven pawns on the board are isolated.  Forget about pawn structure, after move twenty-six, it’s every pawn for itself.

Suhas Kodali and Jithu Sajeevan of Bristol tied for 1st place of the 2018 Nathan Hale Open, each winning $120.

Suhas scored three wins against players with average rating of 1866. Jithu scored three wins against players with average rating of 1800.  Suhas and Jithu rode in a carpool.

Suhas won against Mike Smith, and Jon Smucker NY, then Joe Bihlmeyer of Durham in final round.  William Torres of Cheshire lost round one to Jithu, and round 2 with Joe Bihlmeyer.

We had 6 players from Central Conn, 3 players from Eastern Conn, 2 from Rhode Island, and 1 from New York.  The average rating for the 12 men was 1700. Five played here the prior month, March.

I wish all the tournaments I run were like this one. Each game was high-quality, and hard-fought.  Players commented on how smooth everything went, no disruptions anywhere.

Joe Bihlmeyer analyzed players' games in the skittles room, always with an audience of a half dozen players.

Financially the tournament broke even with expenses.  Lunch was all prepared ahead of time so I was able to supervise all games to completion.

My thanks go out to each player for attending. We expect many of these strong players at our May 19 tournament.

Our Carpool Program got us an extra 4 players this time so we are keeping the program.  We had two sets of carpoolers this time. Carpoolers benefit by not being paired together, and each getting $5 off.

We are keeping our $5 discount for hardship. Other discounts were not utilized, so are being discontinued.

Our next tournament is "2018 Constitution State Open" on Saturday May 19.

Chess Game of the Week, by Alan Lasser

 
Last week’s lead was incorrect, I should have said it has been may years since an American “won" the world championship.  The last time an American “played" for the world championship was Gata Kamsky in 1996. 
 
  I tied for first at last weekend’s Chess Fool’s Day tournament, highlighted by one of my better Weissman’s Defenses.  My thinking has long been that it is better to play a bad opening well than it is to play a good opening poorly.

Chess Game of the Week, by Alan Lasser

  It has been many years since an American played for the World Championship of Chess.  Back then, the match was front page news and generated enormous publicity for our game.  Hopefully the forthcoming attention will once again benefit our local chess organizations.  Of course, the last time our guy was a human-interest story, a force unstoppable except by himself.  This time we have the clear underdog, so the focus will probably be on the games.  A fascinating match-up last week previews what might be in store for us.
