Hartford Open Sept 21-23, and 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.

2018 CHARTER OAK OPEN

Sept. 29  -  Coventry Connecticut

 


Coventry Chess Club is now conducting "free beginners chess tournaments" during each of its tournaments (monthly, next one is Sept 29).

These events are listed on many of the local community calendars, so as to attract new chess players from the general public.  The beginners tournament will run concurrently with round-one of the advanced (rated by U.S.Chess) section.

Competitors from the open tournament are encouraged to offer advice to these fresh new players.  These kids came to see what chess can offer them, this will be their first impressions of chess.

Sometime in early October 2018, Connecticut Chess Magazine will attain 150,000 total visits to its website.  The website began in May 2010. It started up slow, but the membership built up steadily.

A boost in readership occurred in May 2016, when the Coventry Chess Club began running monthly tournaments.  Tournament participants now have a very good reason to subscribe; to get tournament announcements and reports.

The magazine is the official state chess publication for Connecticut. CCM features an updated list of clubs and upcoming tournaments in and near Connecticut. 

Any chess player may subscribe to the email-newsletter for free.  45 percent of our readers came to us via a search engine, 20 percent came via social media, and 22 percent are referred from other chess websites.

Game of the Week, by Alan Lasser. Plus more...

Good news chess fans, 2461 rated Yixin Li has returned to UMass this semester and he intends to play in more USCF tournaments. He had a lot of fun at the Chinese national team tournament this summer. In this game he had to navigate through one of those treacherous more-pieces-than-pawns positions to score the point.

Alan Lasser's Game of the Week

  The most dramatic more-pieces-than-pawns position was the final game of the 1910 World Championship Match, which was twelve pieces with five pawns in the critical position.  That was very good strategy on Lasker’s part, the position was too complicated for Schlecter to handle, he captured one of the remaining pawns, and that tactical error cost him the title.  My two computer programs can’t stop arguing about this week’s game.  No wonder, after move 24 there are eight pawns on the board with the fifteen remaining pieces;  after move 28, it’s fifteen and six.  It sort of makes me wonder what the other bughouse board looks like.
