3M Club Chess Club Newsletter
Editors: Ken Goebel, Steve McRoberts Vol. 1, No. 1
_______________________________________________________________________
We're Back!
After a long hiatus, the Newsletter is back! We are open to suggestions as to content. To start off, we have given the majority of the focus to games played by members. Ken Goebel has input these into his chess-playing software for analysis, and we will include the players' comments (if any) along with the computer's analysis. This is the reason we have requested that scoresheets be turned in: we get content for our newsletters, and you get free analysis of your games! It's a win-win situation!
Ideas for future columns in our newsletter include: "Meet the Players" (mini-interviews with members of the club); "Novice Corner" (an instructional column). If you have any other ideas about things you would like to see in your newsletter (or if you have anything you'd like to contribute) please contact Ken or me.
League Tournament One
Tournament one is already two-thirds over! So far, the team scores have been very close, with Larry's team holding a slight lead. Due to one player backing out at the last minute, the teams had to be regrouped, and the pairings redone. This caused a lot of confusion. Due in part to this confusion, some of the games in round 3 were not played, and therefore round 3 will not be counted for team points (though it will count for indivdual game points and rating points).
Correspondence Tournaments
We currently have three sections running in our new Fall 2001 correspondence tournament. Each section has 4-6 players. The tournament is quite cosmopolitan, with players from Germany, England, Mexico, and of course, the U.S.A. We also have an expert-rated Canadian waiting in the wings for a few more players to start another tournament: so if you'd like to try correspondence chess, let me know.
Getting the Most Out of the Published Games
We will try to publish all of the OTB league games that are turned in without the "Do not publish" box checked. Some of these games may only be interesting to the original players of the game, while others will be of general interest to all. But we won't make such distinctions. Nor will we publish the names or ratings of the players; every game is potentially interesting, not just those of the top-level players.
Ken's chess-playing software includes "Rebel Tiger" and "Rebel Century". The analysis of the Tiger gives a score for the move made, where a positive number is good for the player making the move, and a negative number is bad for the player making the move. On this scale, 1 is equivalent to a Pawn. The Tiger than gives the depth it analyzed to (in "half-moves"), and then gives its opinion of what would've been a better move, followed by the best moves by both sides from that point on.
The Century software is similar to the Tiger, but also gives a score for its recommended move. The Century software will be used exclusively in the future.
Comments by the players will be prefixed by W: or B: to indicate the White or Black player's comments, or ED: if someone else comments on the game.
