Best Game of Round 6

Alex Cherniack
A spectacular mating combination and a leader board thrown into disarray with only one round to go, what more can you ask for? How could it be any game other than Chase-Cherniack?

4.5 Chase, Mac Intyre

4.0 Martirosov

1.5 Williams

Round 6: Slive-Mac Intyre 0-1

Paul Mac Intyre

Mac Intyre takes advantage of several mistakes by Slive to comfortably win a tactical game with a number of interesting material imbalances. Paul provided the annotations below.

[This is a very rare move and doesn't seem to really gain any advantage]

8…h6 9.Be3 c6

[This move is actually extremely clever. I think a classical approach to this position would be 9....Ng4 10.Bc1 f5, but after sitting and looking at that position, I didn't feel all that comfortable with it. Instead, I correctly predicted that my opponent's next move would be 10.h3, after which I planned to transpose to the exd4 systems. In these systems, White naturally wants to play f3 to bolster the e-pawn. However, having already played h3, the dark squares on the kingside would become uncomfortably weak]

10.h3 exd4 11.Nxd4 Re8 12.Qd2?! Nxe4 13.Nxe4 Rxe4 14.Bf3 Rh4!

Hauptturnier standings

the hop
With the pace of the Championship slowing down (no games last week due to the Annual Meeting and only make-up games this week) it seems like a good time to check-in on the Haup. Since several players still have many games to complete it is hard to say who is actually leading at this point. Fuhro, Iglesias, Sullivan, Vernon and Dean all look like they remain in contention for the crown.

6.5 Fuhro(3)

6.0 Iglesias(3)

5.0 Sullivan(4)

3.5 Vernon(5), Lee(4)

3.0 Dean(6)

2.0 Foye(4), Hager(4)

1.5 Gorczyca(4)

1.0 Oresick(5)

0.0 Theil(withdrew)

(#) - Number of games remaining to be played

Note: Theil withdrew after losing to Oresick in Round 1. As a result, all the other players' scores reflect a forfeit win.

BCC election results

ballot box
In a big surprise, an actual election broke out for the position of Vice-President during Wednesday's annual meeting. After a short but fierce campaign, incumbent Kent Leung was trounced 11-1 by his opponent. So far, no court challenges have been filed.

Here are the results:

President - Paul Mac Intyre
Vice-President - Bernardo Iglesias
Treasurer - Bob Oresick
Clerk - Ed Foye

Board of Directors - Alex Cherniack, Natasha Christiansen, David Glickman, Mike Griffin, Greg Hager, Jon Lee

After the meeting, Paul appointed Chris Chase as an additional director.

Ratings magic

magic wand
In a recent post I said:
"It might be reasonable to assume that the recently published 10/04 USCF ratings are a better measure of the players' strength upon entering the Championship than the "official" 8/04 numbers. Of course, it might also be reasonable to believe that ratings mean 'not a nit' in any particular game."
Here is a perspective from someone who has given the topic a lot of thought:

Chess ratings are not devoid of meaning, but they are unquestionably imprecise. As I said last time, we need to keep in mind that FIDE ratings are not the precise measurements we would like them to be. In fact, nobody really knows just how effective the FIDE ratings are at measuring the "true strength" of a player. However, based upon the research that I performed a few years ago in developing my Chessmetrics historical ratings, I don't think it's too far off the mark to say that the estimation error in an Elo rating is normally distributed, with a standard deviation of 50 rating points. That means if somebody has a 2550 rating, we can only be about 70% sure that their "true strength" or "current form" is somewhere between 2500 and 2600. And we can only be 99% sure that their "true strength" is between 2400 and 2700.

I'm sorry about this; I really am. I wish I could tell you that ratings are nice and accurate. I wish I could wave a magic wand and tell you that I have a super-magical rating formula in my bag of tricks, but I don't. In all honesty, I simply don't know who the strongest player in the tournament is. They haven't played enough recent games to let me figure that out with any certainty.

Election Night 2004

Hanging chads

Red states, blue states, 527s, negative campaigning, hanging chads ... it's time again for the annual election of the Officers and Board of Directors of the Boylston Chess Club.

Tonight the Championship and Hauppturnier take a hiatus to make way for the club's annual meeting. In point of fact, elections at the BCC are not generally reflective of American democracy; instead they tend to exhibit attributes more commonly found in countries like:

  • China - There is only one candidate running for each office and they are all voted in by acclamation.

  • Iraq or Afghanistan - After significant begging and cajoling a member agrees to accept a nomination for a key role. After being voted in the membership focuses its attention on killing him.

Round 6: Chase-Cherniack 0-1

Alex Cherniack

It’s a whole new ballgame! The players reach an unbalanced position where Black’s central pawns and two bishops confer an advantage. White’s minor pieces find themselves on the wrong side of the board, unable to lend assistance to their beleaguered King. After White makes a slip, Black closes out the game with an impressive Queen “sacrifice” leading to mate.

Best Game of Round 5

Vadim Martirosov
For the 5th round, the choice is a difficult one. The Mac Intyre-Williams "blunderfest" can be easily dismissed; however, in the other three games the winners played well but the losers generally made it easy for them. I've decided to chose Cherniack-Martirosov in order to recognize the fact that Vadim has yet to lose a game in the Championship.

As always, your opinions are welcome.

Chris Chase

An interesting game to determine the leader as the tournament crosses the halfway point. Black hands the advantage to White with his last move before the time control. While Chris begins the adjournment well, an imprecise move allows Paul to reach an equal (drawn?) ending. However, Paul decides to try for a win and loses instead.

... it was just a coincidence?!

water dispenser
On Monday evening, October 11th the Glickman-Chase adjourned game resumed. Since this was not a tournament night, only the players and TD Bernardo Iglesias were expected to be there. However, Paul Mac Intyre also stopped by. He said that he didn't know we were playing that night, " was just a coincidence."

Surely as President, Paul has many good reasons to be at the club. However, he did admit that he was very interested in the outcome of this game (hoping against hope that Glickman might be able to nick Chase for a half-point and bring Paul that much closer to the leader). Hmmm, the plot thickens.

Suddenly, about a half-hour into the playing session - while Chase was on the clock - Paul changed the bottle on the water dispenser just a few feet away from the players. For the next several minutes all we could hear was the deafening sound of 'glub! glub! glub!' as the water dispenser refilled. Could Paul possibly have been trying to influence the outcome of the game by disturbing Chris' concentration? He said, "... it was just a coincidence."

Round 5: Cherniack-Martirosov 0-1

Vadim Martirosov

It was not a good night to be named Alex. White blunders first the exchange and then a piece. As a result, Vadim remains undefeated and within striking distance of the leader.

My opening preparation for Round 5

This game was my inspiration for my opening preparation against Chase. Needless to say, things didn’t go as easily for me as they did for Vlady.

Round 5: Riordan-Slive 1-0

Charles Riordan

The players follow 13 moves of theory which, unfortunately for Alex, lead to a position which is much better for White. In a difficult position, he misses a Zwischenzug and rapidly goes down to defeat.

[The psychology behind this mistake is understandable. Black realizes that he is going to have to play Kf7 and wants to make sure queens are off the board before he exposes his king. Based on his facial expression during the game, Alex realized that the e6-pawn was coming off with check just after he captured white's queen. Interestingly, Fritz considers 14...Kf7!? roughly equal]
