Game of the Week by Alan Lasser

3 players tie for first place at GREAT HARTFORD OPEN Posted: 18 Mar 2018 08:09 AM PDT  Two national experts and a new player from New York tied for first place of the 2018 Greater Hartford Open, each winning $80. Suhas Kodali, Joe Bihlmeyer, and Jon Smucker each scored a total of two wins and one draw during the Swiss-style tournament held on March 17 in Coventry. Christopher Scarborough of Plainfield finished with two wins, losing his last-round game with Kodali. Smucker was able to hold off Bihlmeyer to a drawn game in the last round. Eleven players from the tri-state area competed in this day-long event. Free lunch of hamburgers was provided. Bob Cyr, the Chess Historian for Connecticut, visited us as a goodwill ambassador, brought donuts and cookies, and helped us by playing a game as houseman. Thanks to the New Britain Chess Club and the Norwich Chess Club for their representation in this tournament.

  When a grandmaster sacrifices three pawns, they usually get an attack, so this week it’s Nakamura’s king who goes for a walk.  Working against him is the time limit for this event, game/25 with ten second increments.  He succeeds in taking one computer-approved king-step after another until he doesn’t have enough time left to find complicated solutions.

The Kopec System 1.e4 c5 2.Nf3

After I played in the Kopec Memorial tournament last June, I started playing the Kopec System. The basic idea is that White’s white square bishop gets to the optimal c2 square from which it can affect both sides of the board. The practical advantage is that IM Danny Kopec’s system is still little known and takes the opponent out of their book preparation right away. I have now played ten recorded club games with good results, so I am presenting all the games here as an example of how to go about assembling your own computer-analyzed opening files. This opening was never included in Modern Chess Openings so I use my own games to stake out the basic variations, add the obvious moves that haven’t been played against me, and then I give all the possibilities the Stockfish treatment.

Alan Lasser Game of the Week

  Just like the rest of us, grandmasters can try too hard to win.  The king has to go for a march across the board and just when it looks like the opponent has a three-time repetition/perpetual check ready, the GM chooses wriggle out dangerously.  The result is an unusual position on the thirty-seventh move, all of White’s pieces are back on the first rank, and the extra rook isn’t any good at all.

Alan Lasser column - BONUS - 2 games this week !

  The third highest rated nine year old in the country dropped by the UMass Chess Club on his way to a Boston tournament.  He certainly impressed the locals in these games, I had a bad endgame and our first board had a bad middlegame.
