​Mechanics’ Institute Chess Club Youth Movement Taking Over Brandwein TNM Championship Section

On boards 1 and 2, FM Josiah Stearman (blue Cal hat) and CM Sriram Krishnakumar (red US Chess hat) put in strong performances to take control of the leaderboard

The Bay Area is packed with rising star chess talent, and the Brandwein TNM concluded its 4th with our TNM youth stars rising to the occasion, as current and past members of the U.S. Chess All-America Chess Team put on a show. 

On board 1, FM Josiah Stearman put on a dominant performance in defeating NM Carlos Davila to take sole possession of first in the TNM Championship section with a perfect 4/4. On board 2, the U.S. #17 ranked 11-year-old CM Sriram Krishnakumar put on an amazing, disciplined, and technical performance in defeating defending champion FM Kyron Griffith. He now has sole 2nd place in the standings at 3.5/4, with the half point the result of a bye round.  He is having an outstanding tournament, having defeated IM Elliott Winslow the week before. Also moving up the leaderboard is the U.S. #18 ranked 15- year old NM Arman Baradaran, who defeated the always-tough NM Aleksandr Ivanov to be tied for 3rd with 3/4. Also at 3/4 is U.S. #2 ranked 11- year old NM Eric Yuhan Li, who bounced back from a loss to Stearman last week with an impressive win against WFM Natalya Tsodikova. The remaining rounds will likely see some of the nations top young players battling to become the Brandwein TNM champion.

NM Eric Li ponders his next move against WFM Tsodikova

In the A/B section, Mansoor Mohammad continued his section dominance with a win over Teodoro Polares. He stays perfect with 4/4. Rafik Robeal and Robert Drane close behind with 3.5/4.

In the under 1600 section, fan favorite Jerry Simpkins delivered another exciting game in defeating Jahaan Ansari to remain perfect. Also with a perfect score is Sterling Albury, who defeated Michael Baer. It looks like we will have a match of undefeated players next week on broadcast board 10!

Another full house at the club!

U.S. Open and National Open Champion GM Illia Nyzhnyk Visits Mechanics and Plays in August Monday Night Rapid!

Monday August 26 was a very special day, as GM Illia Nyzhnyk visited the Mechanics’ Institute Chess Club for the first time. He gave a simultaneous exhibition at noon, a lecture at 5:15pm and then played for one of the greatest titles of all, Monday Night Rapid Champion.

GM Nyzhnyk discusses his simul game with Andrew Schley

For the simul, 14 players played in all, and he won 13 and drew 1. IM Elliott Winslow made the lone draw. For the rapid, He went 4/4 and tied for first with IM Teddy Coleman.

GM Nyzhnyk also gave a great lecture of a game from the U.S. Open. It was a great visit and we were honored to have him come spend the day with us. He is captain of the powerful Webster University chess team led by GM Susan Polgar, and we thank her and Judit Sztaray in working to make this visit possible.

CalChess Election This Saturday

The CalChess Board of Directors will have a meeting and election this Saturday to vote on 4 open seats for the Board. I stepped down after serving almost 2 years in July, and the vacant seat of the late Ruth Haring is also open. 2 other seats are also available, from Lynn Reed who is not seeking re-election and the seat currently held by Richard Koepcke, who is thankfully seeking re-election. The election and meeting will be held on Saturday at 6pm at the Santa Clara Convention Center, site of the Labor Day State Championship.

While the filling of the seats is a foregone conclusion, since only 4 people have submitted candidacy for the 4 open seats; Richard Koepcke, Ashik Uzzaman, Sujay Roy and Dr. Salman Azhar, I encourage every member of the chess community to attend the meeting and learn more about what CalChess is and how it can help the community. Here are the candidate statements:

Candidate Statements
in alphabetical order

Salman Azhar
Even though I have been involved as a co-founder or an investor in over 100 startups, BayAreaChess is my favorite due to its lasting influence on so many lives. I am returning to BayAreaChess to set the course for the next ten years and foster greater collaboration across CalChess community.
I want to invest in our chess community so that we can continue to produce great human beings and class chess players. I served on the CalChess board for about ten years and consider it an honor to have an opportunity to serve again.

Richard Koepcke
I started playing tournament chess in 1975; and have been involved with in some capacity on the Tournament Directing / Organizing side of Chess tournaments since 1985 (though these days I am mostly a TD and not an organizer). I have also been involved with CalChess from the mid to late 1990s to the present in some capacity or another. Have served as President, Secretary for many years in the past and am currently the Organizations Treasurer. I am also a FIDE Arbiter and have reached a TD certification level of Associate National Director ( ANTD ).
One of the main roles that CalChess plays is in sponsoring various State Championships, although it currently sub-contracts out the actual organizing of said tournaments. This includes the Open State Championship traditionally held over Labor Day weekend, State Scholastic Championship, and various smaller State championship tournaments. Regarding evaluating bids for Championship events, it helps to have people who have actually organized and run events of some size, which is one aspect I bring to the table as a member of the CalChess Board. CalChess is also the main interface between US Chess and local members and clubs. To better support the latter, my focus will be to gradually improve the Website, and to update the club and tournament list on a regular basis.

Sujay Roy
Sujay Roy has been teaching Chess to Bay area students. Many of them have won Championship in California State level tournaments and have achieved National ranking in US Scholastic Chess. Mr. Roy was a State Champion and National level player in India and has served as Chess coach at Weibel Elementary School, Fremont and India Community Center, Milpitas. He has been Tournament Director at California State Scholastic Chess Championships for many years.

Ashik Uzzaman  (https://dragonbishop.blogspot.com)
Being a chess player and chess parent for a long time in the bay area, I believe I have the right aptitude to help out the chess players, families and organizations in Northern California. If elected, I will work with the board members to anything within my capacity including the followings.

  1. Improving the CalChess Web Site
  2. Write article in CalChess Journal
  3. Chess Event Coverage
  4. Improve CalChess Social Web Presence
  5. Attracting Corporate World Into Chess


I have been critical of CalChess in the past, as it could have more transparency and do more to promote awareness, engagement, and offer more to the chess community than just voting on who gets what tournament. I have also been critical of the amount of organizers that make up the Board. While it is a benefit to have people who are active participants in the chess community on the Board, there should be also be a balance of members of the general chess community to provide oversight and another voice and opinion. I personally am excited at the candidacy of Ashik Uzzaman and Sujay Roy, as they provide a fresh face and look to the Board. I am also excited Richard Koepcke has decided to run again, as his knowledge of the history of the chess community and moral integrity are without question. I also wish good luck to Dr. Salman Azhar, who has returned to run Bay Area Chess and will serve on this new Board.

I do hope the Board can make changes that help excite and engage our community. Last year, I led an effort to make voting available throughout the day of the election rather than just during the meeting, which I felt led to more voter participation and less disenfranchisement. Election day last year was exciting with people campaigning, candidates rallying the get put the vote efforts and issues being discussed. We had I believe 8 candidates for 4 spots and had the most number of votes cast than had been done in some time. Whatever the results, this level of participation was good for the chess community.

This year it seems we have gone back to people not being aware or interested, and we have again disengagement and little to no knowledge of CalChess from the general chess community. The CalChess Board every year states at its meeting that it will work to improve processes and be more transparent etc. etc. but very little happens currently on the Board than voting on bids to organize events. This is an important duty, but CalChess should do more. It is difficult also when half the Board must abstain from a vote because they have an interest in the outcome. This is not very representative, and the reason I believe we need more engaged people from the general public to be a part of the Board.

A few Board members cannot do this alone, and I surely was not the one that would be able to bring about change. There are voices on the Board wanting to make a difference, and we need our chess community to help them hold others accountable. We have amazing people that make up our chess community, I hope through awareness and outreach, we can encourage them not only to participate and run, but to seek leadership positions on the Board to bring about new ideas and a new leadership perspective.

Wednesday Night Blitz Returns!

 

The Wednesday Night Blitz Tournament has resumed after a 3-month hiatus! Smoothly run as usual by organizer Jules Jelinek, the August 28th edition had a turn out of 10 players and was won by (drum roll...) Jules Jelinek with 5.5 from 6 games. Carlos Davila was 2nd with 4.5, and Joe Urquhart and Jeff Senick tied for 3rd with 4 points.

Scholastic Corner

by Judit Sztaray

August Scholastic Swiss – Report

We had another great monthly tournament for our scholastic players at Mechanics’ this past Saturday.  Strong field in the top section with four players over 1000 USCF rated. At the end of four rounds it was Austin Li who took sole first place, with Nathan and Jon taking clear second and third place. Middle section also produced a clear winner, Kevin Sun, came back strong and confident after skipping summer to focus on his training. The lower sections had some strong beginner tournament players, and Alen Sabitov came out as a clear winner, with perfect 4.0 score ahead of 9 other players.

Gearing up for a fun and busy September

Scholastic chess will be at Mechanics’ again on September 8th, as well as we will be starting a monthly tournament at a satellite location, in Cupertino on September 15th. This will hopefully allow us to spread the name and information about our historic chess club, and build up our legacy outside of the city one small step at a time.
Another new development is that we are adding a fun and fast blitz tournament right after the swiss. Blitz is a unique chess tournament format where players have to play super fast. This particular tournament’s time control is only 5 minutes for each players, and no delay or increment time. It’s a fun way for players to learn and get used to playing with a clock, and learn to follow their instinct.

Chess: images and social media.

By FM Paul Whitehead

I work for the Mechanics’ Institute, and have been a regular contributor to both the Chess Club’s and the Institute’s Facebook pages.  The Mechanics’ Institute is a cultural institution, and chess is everywhere in the culture – I wanted to show that.

Starting the Chess Club’s Facebook page was for me a no-brainer: I have a background, and a strong interest, in images and chess.  I instantly understood that there was a wide culture of chess–imagery out there, spanning the human comedy from the tragic to the sublime.

People everywhere, from all social-strata, are photographed playing chess, both off-handed and serious: in barbershops and bars, churches and cafeterias.

Chess is in the Movies and Hollywood; it is on TV, and prevalent on Madison Avenue. Chess becomes satire and political commentary; it is used to manipulate and to entertain.  The imagery of chess illustrates brains, persistence, relaxation, complexity, and focus.

People are photographed playing chess on roller coasters and at the bottom of swimming pools.

Chess, literally, is everywhere.

1. The Mechanics’ Institute Chess Club

I will start with the club and move outward.  Future posts (I hope) will include Surrealism, portrayals of women in chess, celebrity culture and Hollywood, humor.  Stay tuned.

The MI Chess Club is quite new to social media, and we are just getting started – we stream live video on YouTube and Twitch, as well as posting to Facebook.  We have an extensive image collection, used liberally in past and present newsletters.  Pictures of World Champions in our club are priceless: Jose Capablanca, Alexander Alekhine, Vassily Smyslov, Mikhail Tal, Boris Spassky, and Anatoly Karpov.  All visited and were photographed: giving simultaneous exhibitions and lectures.  Or just playing an off-hand game!  Bobby Fischer was here twice, but never photographed: an unpardonable sin in these days!

Now we are catching up with the times a bit: all the pictures below were taken in the last two years, and they show a thriving and vital chess club.  Not only a fantastic place to watch and learn, but look – what an amazing place to play chess!

All images are untitled - these are all great previous FB posts

Nick de Firmian''s Column - Magnificent Magnus
Week 4 – Defense
 

One thinks of a great chess player as a force of will, pressing an opponent until he/she cracks. The great player will have some advantage of better development, more force (pieces) or some kind of positional plus. If there is an endgame, the great player will be working the small advantages to convert even dry positions into a victory.

Yet it is never that easy in real life. Even the best players screw up sometimes and find themselves in a difficult situation where they are fighting for their lives. A great example of this would be the game Kramnik- Carlsen, London 2010 which we showed in newsletter 879. There Magnus struggled on in a lost position but took every chance he could to make the win difficult. He was rewarded in the end with a miracle draw.

There is also the circumstance that you have an aggressive opponent who throws the kitchen sink at you, when you have no choice but to take the material and hold the defense. The art of defense is something every champion must refine – what if Mohammed Ali couldn’t take a punch?. Korchnoi was a player who reveled in the role of defense, and every World Chess Champion learned the hard way to be a great defender. We give two examples below from Magnus on how to defend against and attack.

(1) Hannes Hlifar Stefansson - Magnus Carlsen
European Team Chess Championship Crete GRE, 2007

1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 c6 5.Bg5 h6 6.Bxf6 Qxf6 7.e3 Nd7 8.Bd3 dxc4 9.Bxc4 g6 10.0-0 Bg7 

​ 

The opening has given Black the two bishops, but more space and development to White. Stefansson, Iceland''s top grandmaster, proceeds to take space on the queenside. 11.b4 0-0 12.a4 e5 13.a5 exd4 14.exd4 Rd8 15.Re1 Nf8 16.Qb3 Be6 17.Rad1 Bxc4 18.Qxc4 Ne6

The opening play has been sound by both players thus far, but now Sefansson decides to advance and attack with an aggressive sacrifice. 19.Ne5!? Qf5 20.Nxf7?!

20...Kxf7 21.Re3 Diagram 

The knight on e6 is pinned and White threatens to win the queen with 22. Rf3. A defense like 21...Bf6 22. h3! would threaten Rf3 and Ne4 winning the bishop. So how to defend? 21...Bxd4!

Magnus crosses up Sefansson''s plan with an aggressive defense! He sees his queen will be lost, but finds a weakness in the White set-up. This is always the best way to defend if you can do it - push your own plans through despite the attack of your opponent. 22.Rf3 Qxf3! 23.gxf3 Bxc3 24.Rxd8 Rxd8

Here Sefansson noticed the problem. He has won the queen but ended up in a materially losing position as he cannot take the bishop on c3 due to 25....Rd1+ 26. Kg2 Nf4+ with a knight fork on the queen. White''s attack achieved was it was supposed to do, but it wasn''t enough. Score one for the defense. 25.f4 Rd4

White resigned as he still cannot take the bishop and the three black pieces overwhelm the white queen. 0-1

 

(2) Anand,Vishy - Carlsen,Magnus
World Championship, 2013

This was the 9th game of the World Chess Championship of 2013. Vishy Anand was the champion and Magnus the challenger. After 8 games Magnus had a 2 game lead, so Anand needed to win with White as the match was only 12 games long. 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.f3 d5 5.a3 Bxc3+ 6.bxc3 c5 7.cxd5 exd5 8.e3 c4 9.Ne2 Nc6 10.g4!

Anand is playing an ambitious set-up to take space on the kingside. The imbalanced position is exactly what he wanted given the match situation.  10...0-0 11.Bg2 Na5 12.0-0 Nb3 13.Ra2 b5 14.Ng3 Diagram 

White is preparing a very aggressive kingside and central advance. How to defend? Any pawn move by Black on the kingside could make a target. One rule of defense: try to make sure you have some counter play. 14...a5! 15.g5 Ne8 16.e4 Nxc1 17.Qxc1

17...Ra6! An all purpose defensive move. The rook looks toward the kingside, but it is also defended now by the bishop so that Black can proceed with the b4 pawn break on the queenside. The powerful white attack is coming and the counterplay needs to be quick enough. 18.e5 Nc7 19.f4 b4 20.axb4 axb4 21.Rxa6 Nxa6 22.f5 b3 23.Qf4

Black has a nice protected passed pawn on b3, but White has three advanced pawns and four pieces bearing down on the black king. Can Black avoid getting checkmated? 23...Nc7 24.f6 g6 25.Qh4 Ne8

The black knight has moved 6 times, while the black queen, rook and bishop have been stationairy. Yet they are on defensive squares. Note that 25....h5? would simply have been met by an overwhelming sacrifice. 26.Qh6 b2! 27.Rf4!

Magnus could not just stop the attack, but has gotten his counterplay in the form of a queening pawn. Yet Anand goes for broke! No amount of extra materiel will save Black if Rh4 brings checkmate. 27...b1Q+ 28.Nf1? A tragic mistake by Anand, perhaps due to the high tension of the game and match. A fascinating continuation would have been 28. Bf1 Qd1! 29. Rh4! Qh5 (only way to stop mate) 30. Nxh5 gxh5 31. Rxh5 Bf5 32. Bh3! Bg6 33. e6! Nxf6! which holds game. 28...Qe1

Now Anand saw that his attack does not work after 29. Rh4 Qxh4. He thus resigned the game and effectively the match and World Championship. Cool collected defense by Magnus. 0-1

 




Brandwein Memorial TNM Games Round 4

Annotations by GM Nick de Firmian 

(1) Davila,Carlos (2079) - Stearman,Josiah P (2427) [B33]

A simple development of the queen to d2 would leave White with a small edge due to possibilities on both sides of the board. [19.Qd2+/=] 19...Be5 20.Qb3 f4 21.Ra2?! Kh8 22.Rfa1?! Rxa2 23.Qxa2 f3! Diagram

Now White is in trouble. Josiah has pressed the kingside attack while Carlos was using too much time on the queenside. 24.Qa7? [24.gxf3 is best but still bad: 24...Rg8+ 25.Kf1 Bxh2] 24...Qxa7 25.Rxa7 fxe2 26.Ra1 Rc8 27.Re1 Rc5 28.Rxe2 Nxd5 29.Rxe4 f5 0-1

The opening has been reasonable for both sides and 14...d5 would be a good central break giving full equality. Kyron drifts into a bad position. 15.Rac1 e5 16.Nc2 Bb7 17.Nb4 f5 18.c4!
