Game of the Week, by Alan Lasser

The latest preview of the upcoming world championship match was at the fantastically strong 2018 Norway Chess tournament. In this game our man was clearly outplayed. The champion exploits the Black pawn weaknesses, the backward d-pawn that appears on the board around move twenty and the isolated b-pawn. By move 45 the endgame looks bad, but Caruana plays it out for another thirty moves. The late resignation suggests that the championship match won’t be plagued by short draws.

Game of the Week, by Alan Lasser

The 2018 Constitution Open at the Rob Roy Chess Center of Coventry Connecticut was won by Dan Smith, who hosts the Thursday night Westerly Chess Club at the public library in Westerly, Rhode Island. These two dedicated chess organizers deserve all the free publicity I can give to a small chess area of the wide chess world. In this crucial last round game, Black gets the two bishops against the two knights; but the center is clogged so the knights can keep the evaluation balanced until the board loosens up a bit.

REPORT ON 2018 CONSTITUTION STATE OPEN

Dan Smith of RI won clear first at the 2018 Constitution State Open held May 19 at the Rob Roy Chess Center in Coventry Conn.

Smith runs his chess club every Thursday 5:30 pm at the public library of Westerly RI. Smith won $160 and picked up 111 points on his USCF rating.

Four players tied for 2nd place; Mark Bourque, Nakul Ramaswamy, Rev. Hugh James and Rob Roy. Each won $20.

Bourque runs his chess club Thursdays 7 pm at the Stafford Springs town hall. The Reverand Hugh James runs a church in Norwich, and Rob Roy the center in Coventry.

Fairfield County Chess Club in Norwalk also selected May 19 to host a team event, (57 players), which ultimately took four players away from Coventry.

Our attendance was merely 8 players, down from our usual 12. To break even with expenses we needed 12 players. We finished $120 in the red. We are going forward with plans to conduct our next tournament for Saturday June 23.

Currently there are no other chess tournaments scheduled for June 23 within 80 miles, so we expect our top players to be back again in full swing.

Chess Game of the Week, by Alan Lasser

Who is this man ? Scroll down below for answer

My previous count of the recorded games of Yixin Li was a bit off, omitting his blindfold game against Rod Hajaj, his game on first board at the last UMass-Amherst match, and there are 14 recorded games against me, not 13. The revised total is 25, but many are game/15s of dubious quality. Below are a few more of the better ones.

"BURGER LUNCH" BACK ON MENU AT COVENTRY CHESS

I experimented with a "cold lunch" menu on April 21, to try to eliminate the need for a cook at lunchtime. (dishes to be prepared that morning or night before).

It was nice, for me, the TD, not needing to go outside (away from the games) for 20 minutes to go cook. But as the cold lunch was merely okay, hot burgers are enjoyed so more.

For May 19, I will get 24 freshly-made patties, and 24 buns. We will have all the fixins. I discovered grilling burgers is a skill few people have. I have this skill.

After Round One is finished; your TD will go outside and fire up the grill. I cook to medium-well. Lunch break will now be 10 minutes longer, while we wait for hot and juicy burgers.

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.
