Brandwein TNM Sees Favorites Cruising Through First 2 Rounds

The second round of the TNM concluded with pre-tournament favorites FM Josiah Stearman and NM Eric Yuhan Li staying perfect after 2 games. Defending champion FM Kyron Griffith won in a battle against Kevin Kuczek and is at 1.5/2 after a first round bye. The breakthrough in the open section thus far came from Ethan Boldi, who defeated WFM Natalya Tsodikova to take a share of the early lead with 2/2. Also entering the challenge at the top is former University of Virginia standout NM Jeevan Karamsetty (2296), who also won and is at 1.5/2 after a first round bye. The action will intensify for round 3, with only 3 players with perfect 2/2 scores in the open section

Viewers got to experience the top board of the TNM from a new camera angle

In the A/B section, Mansoor Mohammed continued his great run at Mechanics, following up his previous TNM A/B section win with a 2/2 performance in this current event after defeating strong blitz player Erika Malykin. Strong club regulars David Rakonitz, Adam Mercado and Teodoro Porlares are also perfect thus far after 2 rounds.

In the under 1600 section, Jackie Cowgill pulled off an upset of Albert Starr, taking down one of the section favorites. Perhaps the phrase “Any Given Tuesday” should apply to the TNM, as anything can happen at any time. Great game for Jackie!

In a tough and crowded section, John Chan, Jahaan Ansari, Jerry Simpkins, Charles James, Ton Carter Allen, and Sterling Albury all share the early lead with 2/2.

U.S. Open Champion Illia Nyzhnyk to visit Mechanics’ Institute Monday August 26 and Play in Monday Night Rapid!

GM Nyzhnyk waits for his last round opponent at the 2019 U.S. Open

U.S. Open Champion and National Open Champion GM Illia Nyzhnyk will be visiting the Mechanics’ Institute on Monday August 26! He will perform a simul in the afternoon, give a brief lecture prior to the rapid, and finish the evening off by going for the coveted title of Monday Night Rapid Champion. We will also take this special opportunity to provide a live broadcast of this rapid event with commentary, so it will make for a very special rapid evening. To register for the simul or the rapid, please follow this link:



Tournament Director's Corner

I had an incident  in a recent rapid I talked about where I was called to a position in which both players were in check. This happened at the very same moment when a player on the top board called me over to count moves in a king and rook versus king and bishop endgame. 

What I ended up doing as the sole TD for the last Monday Night Rapid was to tell the players on board 1 to pause the clock and that I was going to resolve a dispute at another board first, and then be right over. I felt that counting moves was a lesser priority than resolving two players simultaneously in check. When I went to the board, I asked if both agreed that it was in fact the position as they both understood it. One of the players believed the king may belong to a different square, which would have placed it out of check. When I asked the other player if that seemed right, he agreed. So I let play resume, with the king out of check, and the player in check, making the next move. When I returned to the other game, I counted moves. At move 30, the king and rook prevailed over the king and bishop, when the bishop got trapped in the back pinned.

I asked a very experienced TD about this scenario when he visited the club this week. FA Richard Koepcke has a wealth of experience running tournaments and is very active in USCF governance, especially as it relates to tournament directing. He said that I could legally have a spectator count moves on my behalf if my attention needed to be directed elsewhere, which is good to know. The reason is the simple counting of moves does not involve specific tournament rules expertise, so this is a viable option. With regards to the simultaneous check position, he said he also would have verified the position with both players. Had both agreed it was the position, I would have declared the game a draw. Because it was a rapid time control, no notation was required and so verification of the position could not happen. This would also have been the case had the position in a delay time control had gone under 5 minutes from either player. 

While many rules are specific in chess, or at least refer to rules from which TD’s can make interpretive rulings, there is enough flexibility to make a reasonable judgment in those cases that are not clearly specified. It is one of the joys of tournament directing to protect the integrity of the game and to think about situations that make the game fairer. 



Musings From the 2019 U.S. Open

The U.S. Open is a great open event, one in which anyone can compete for the right to play for large cash prizes and a spot in the U.S. Closed Championship. What many don’t know is that it is also the time when U.S. Chess governance is in full swing, bringing together policy makers and political chess representatives from all 50 states. I will focus on one specific part of governance that I feel is very important, and one I have the honor to be a part of.

There are several committees that help inform the U.S. Chess Executive Board on ideas and ways to improve our chess community. For example, The Ethics committee may debate ways to improve the integrity of the game and ways to prevent cheating at events. The Women’s committee may discuss ways to engage more girls and women in chess. Each committee has a Chairperson, usually a state delegate, and a fixed set of committee members. I have the pleasure of serving on the Clubs committee, which is chaired by our very own Judit Sztaray. Because family obligations, as well as a rather big simul event at Mechanics, prevented her from attending the U.S. Open this year, I got the opportunity to run the committee meeting along with Sophia Rohde from New York and Paul Covington from Colorado. 

Over the last few months, we have all been working on two very important things; constructing a survey to give to our members to learn more about how they feel about chess clubs and how we can engage them more, and creating an updated Guide To Starting a Chess Club. This guide is to help people who want to start a club, or give ideas to those who want to improve a current club. The goal is to give people the resources and guidance to start a club, be it for recreation, social interaction, playing rated tournaments, or all of the above. 

We presented to those in attendance what we have been working on, and we had quite a captive audience. We discussed ways to use technology to engage communities, such as creating club vs. club matches using digital boards or through an online platform like We could also use broadcast platforms like Twitch to organize a match and broadcast live from the club, allowing players to see each other and interact. What was clear is that there was an interest and curiosity in clubs from different states like Alaska, Mississippi, and Washington, D.C. and New York to work together in using the common language of chess to learn more about each other. It is through committee work like this, that the opportunity is created to meet other like-minded people that are passionate about chess and finding new ways to leverage the power of chess to make an impact in communities. 

The same holds true for many other committees, where people come together with ideas to elevate chess. For example, I know work done on the Accessibility and Special Circumstances Committee has done a great deal to make chess more accessible to those who have a disability. The committees are a powerful part of the governance of U.S. Chess, and something that is exciting to be a part of.

If you have a passion for chess and want to be a part of making a contribution for the better in a specific area of interest, please look at the committee list found on the US Chess website here:

Shelby Lyman 1936-2019

The chess world lost a true legend this week, with the passing of Shelby Lyman. Much has been written about him, and we will put forward a more substantive column about him in next weeks newsletter, but he was a very generous supporter of scholastic chess in San Francisco, contributing to our Youth Outreach initiatives and helping engage many children in chess who may otherwise not have been able to learn. He was a master, a columnist, and commentator of the 1972 World Chess Championship. The US Chess Federation published an obituary along with space for people to share a story about Shelby. This can be found here:

We will miss Shelby, a true lover and supporter of chess in our community and around the world.

My Ten Favorite Chess Books, Part Two

By FM Paul Whitehead.


Selecting my favorite books has forced me to look at what chess has meant to me, where I placed emphasis (and not), and how far my study took me competitively. I took a lot of pleasure out of game collections: of individual players or tournament books. I played over thousands of unannotated games from Shakhmatny Bulletin, and numerous annotated games from the Chess Informant.  The literature around chess interested me, and I became opinionated about writers: 100 Selected Games, by Botvinnik (1949) bored me, My Best Games, by Karpov (1979) was dry but somehow inspiring. I ignored well-known writers like Pachman, Reshevsky and Fine, finding more in Alekhine, Smyslov and Bronstein. I disliked opening books, yet paid extra attention to certain player’s games, in order to poach their opening ideas. And so on. I found the study of chess to be enjoyable, and the more I put into it the richer the reward I felt - and my results improved as well. I hope your own studies take you far!


6. The Art of Attack in Chess, by Vladimir Vukovic (1965).

First published in 1965, this classic had a great update and revision by John Nunn in 1993.  Almost every attacking motif is here, with chapters on the Classic Bishop Sacrifice, Mating Patterns, Focal Points, how to conduct attacks on the castled and un-castled king, and much more.  To bring home the point with a fantastic attack, to checkmate your opponent with a beautiful sacrifice – this is part of the art of chess, and I daresay the very reason some of us play to begin with!
A valuable companion to The Art of Attack, although less well-known, is The Chess Sacrifice (1968), also by Vukovic.  Studying these 2 books will make you an absolute terror in the chess club!

7. Tal – Botvinnik 1960: Match for the World Championship, by Mikhail Tal (1960).

I think this is the greatest book ever written on a World Championship Match by a participant, full stop. The “Magician from Riga” takes you through all 21 games of this historic match, and along the way you are treated to a rare glimpse into the mind of a genius. This may be the first chess book that paid significant attention to the psychological aspects of the game, as Tal repeatedly references his states of mind as it effects his play and choice of moves during the match. The times taken for each move are also notated, adding a further dimension to this ageless book.


8. Zurich International Chess Tournament 1953, by David Bronstein (1956).

Organized to determine a challenger for World Champion Mikhail Botvinnik, and won by Soviet GM Vassily Smyslov, Zurich 1953 remains one of the strongest tournaments ever held. Like many of the books in my list, there is an emphasis away from thickets of variations, instead there is a concentrating on ideas and psychology, competitive factors and artistry. The student will not only benefit from the high quality of the games played, but also from the penetrating insight of Bronstein into modern middle-game positions and strategy, the clash of plans – the “chess struggle in practice”.


9. Life and Games of Mikhail Tal (1976), by Mikhail Tal.

Is it my fault that Tal wrote two great books, thus taking up 20% of my list? The fact is - legendary chess player aside - Tal was a terrific (if not prolific) writer and journalist. Indeed, this book is an imaginary conversation between Tal the chess player, and Tal the chess journalist.

There are so many wonderful stories and games that I don’t know where to start: from the humorous psychological warfare with Fischer and Benko during the Candidates Tournament in 1959, to the 1974 Gold Medal at the Olympiad in Nice – for 1st Reserve! Tal was still to have many years of world-class competition ahead of him, with a final glory being a shared 1st with Karpov in Montreal 1979.

Tal’s own words to wrap up this classic book:

JOURNALIST. And your plans…

10. My 60 Memorable Games (1969), by Bobby Fischer.

This is THE chess book of my generation, and the blueprint of the New Renaissance in American chess: just “Milk the Cow” and play 1.P-K4 - on principal. Play sharp openings: the Sicilian Najdorf and the Sozin Attack, the Modern Benoni and Kings Indian. Always play to win: in the Opening, the Middle Game and the Ending. 
The truth is on the Chessboard, folks, and this is the book to prove it. Analytically honest and thorough. Almost perfect - without computer analysis.   

People, listen up: this book tells it like it is.  

Fischer takes on the Americans, the Russians and the Yugoslavs – in fact, all who stand in his way. Written 3 years before he took the crown off Boris Spassky’s head, Fischer’s book was already proof that the World Championship was his for the taking. GM Larry Evans provides the pithy intros that set the stage for what lies next: a devastating over the board take-down of the chess elite.  

This book will never die.


Paul Whitehead’s column will take a break for one week, resuming late August.

Scholastic Corner

Summer is ending, School classes are starting and tournaments are continuing ...

by Judit Sztaray

Summer is coming to an end, and Mechanics' Institute Chess Club was hosting a last week of free chess club for interested kids. This past week, we had National Master Isaiah Kim and Coach Andrew Schley teaching the kids chess and show them the fun way of playing. We hoped that they go home with lasting memories and will continue to see them at scholastic classes, and tournaments.

We would like to thank our generous donors, who's donations made two full weeks of free camps possible. 

As the new school year is starting, we are also planning for our classes at schools in San Francisco city and the surrounding cities.
There are two main different classes we offer at schools:

  • free chess classes at deserving schools: usually offered during lunch recess time for anyone in the school who is interested. We are happy to make a difference in several hundreds of kids every week. Since there is no set roster, we mainly focus on providing the safe space for kids to learn the basics, and be able to play chess and socialize over the board.
  • fee-for-service chess classes: parents can sign up for chess classes that we offer usually after school at schools for the fall, semester or the whole year. Since there is a set roster of students, we can implement an educational and fun curriculumn, get kids inspired about progress via small rewards and send frequent progress updates to the parents.

To learn about where we offer chess currently, and read our general mission, plese visit our scholastic page on the website:

If you would like to see how we can offer chess class at your child's school, please reach out to me at [email protected].

Nick de Firmian's Column - Magnificent Magnus
Week 2 – endgames

All world chess champions are good in endgames. They would never get to win the ultimate title unless they had a mastery of the final phase of the game. Yet even among world champions there are some who stand out as virtuosos in that rarified company. Karpov was renown for the final phase of the game, but in history most people regard Capablanca as the first to mark the beauty of showing the world the inner logic to making a small advantage grow in to a decisive final position. Lasker, Fischer and Kasparov were astounding endgame players. All three are remembered for their inventive opening play, resolute middle game handling, but also for their iron logic to convert the most minute edge into the full point.

Still, the endgames of Magnus Carlsen are a wonder, even when it comes to World Champions. Something that sets him apart from his champions colleagues has been his willingness to enter the endgame at an early stage. Most of the great World Champions such as Alekhine, Tal, Fischer and Kasparov would seek opening complications and complex middlegames where the opponent would have to defend against an imposing attack on the king and sift through labyrinth complications. Instead Magnus showed no adversity to an endgame, even from an early age (your author can personally testify to that). It's not that Magnus was ever afraid of complications or eschewed wild attacking positions, but he simply believed that a small edge in an endgame was a worthy result. Thus his early mastery of the final phase  became an art form as he approached the top level in the world. We investigate again this week three of Magnus's endgame victories. The subtle maneuvers he makes to slowly increase the harmony of his pieces and pawns are something to behold.

(1) Nunn,John - Carlsen,Magnus [B30]
Amsterdam, 2006

1.e4 c5 2.Nf3 Nc6 3.Bb5 e6 4.0-0 Nge7 5.c3 a6 6.Ba4 b5 7.Bc2 d5 8.e5 d4 9.Be4 d3 10.c4 b4 11.Qb3 Bb7 12.Qxd3 Qxd3 13.Bxd3 0-0-0 14.Be4 Nd4 15.Bxb7+ Kxb7 16.Nxd4 Rxd4

White needs to develop his pieces and must give back the extra pawn. 17.d3 Rxd3 18.Nd2 Nc6 19.f4 Be7 20.b3 a5 21.Ne4 a4! The game is still roughly even but Black is initiating play on the queenside. 22.Nf2 Rc3 23.Ne4 Rc2 24.Be3 Kb6 25.Rf2 Rxf2 26.Kxf2 Ra8 27.Rd1 axb3 28.axb3 Ra3 29.Rd3

White is still all right but feeling a bit of pressure. 29...f6 30.exf6 gxf6 31.g4 f5 32.gxf5 exf5 33.Ng3 Bh4 34.Rd5 Rxb3 35.Rxc5

35...Rc3! Not fearing the discovered check gives Black some advantage. 36.Rxf5+ Ka6 37.Ke2 Rxc4 38.Rc5 Nd4+ 39.Bxd4 Rxd4 40.Ke3 b3! White could make a draw with precise play, but he must be very careful. 41.Rc1 Rb4 42.Ne4 b2 43.Rb1 Kb5 44.f5 Kc4 45.f6 Kb3 46.f7 Be7

The bishop is stronger than the knight, but with only two pawns left White has great drawing chances. 47.Kd3 Rb8 48.Nd2+ Ka2 49.Re1 Rd8+ 50.Kc4 Ba3 51.Re2 Rd7 52.Rf2 Bf8 53.Kc3 Bg7+ 54.Kc4? Rc7+?! 55.Kd3 Rd7+ 56.Ke4?! Rd4+ 57.Kf5 Rd6 58.f8Q??

Nunn cracks under the pressure, thinking he can get an easy draw against the wrong rook pawn. [58.Ke4 would have held the game.] 58...Bxf8 59.Nc4 Kb3!

Magnus crossing him up. He leaves the rook hanging, he lets his pawn be taken with check -- but White's pieces don't work together. 60.Rxb2+ [60.Nxb2 Bg7 is the point -- the knight is trapped anyway.] 60...Kxc4 61.Rb8 Rd5+ 62.Ke4 Bd6 63.Rc8+ Bc5 64.Rc7 Rh5

The rest is easy for Magnus. 65.Kf3 Rxh2 66.Kg3 Rh6 67.Kg2 Kd5 68.Rc8 Bd6 69.Ra8 Ke4 70.Ra1 Rh2+ 71.Kg1 Rd2 72.Rb1 Bf4 73.Kh1 Kf3 74.Rf1+ Kg4 75.Re1 Kh3 76.Kg1 Bg3 77.Rf1 Rg2+ 78.Kh1 Bf2 0-1

(2) Carlsen,Magnus - Eljanov,Pavel [D91]
Wijk aan Zee, 2008

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.Bg5 Ne4 6.Bh4 Nxc3 7.bxc3 dxc4 8.Qa4+ Qd7 9.Qxc4 b6 10.e3 Ba6 11.Qb3 Bxf1 12.Kxf1 0-0 13.Ke2 c5 14.dxc5 Na6 15.Rhd1 Qb7 16.c6 Qxc6 17.Bxe7 Rfe8 18.Ba3 Qxc3 19.Qxc3 Bxc3 20.Rac1 Bb4 21.Bb2 Bf8

We have reached an endgame with pawn structure somehwhat similar to the last one in that White has 4 pawns vs 3 on the kingside. See the patience that Magnus proceeds with - not looking for direct combinations but slowly taking squares. 22.Nd4 Nc5 23.g4! Note how once again Magnus takes space with his pawns. 23...Re4 24.Kf3 Rae8 25.h3 f6 26.Ba3 Kf7 27.Rc2 Na6?! 28.Bxf8 Kxf8 29.Rc6 Kg7 30.Nb5!

Suddenly the white pieces have tactical threats. Yet that's not what beats a 2700 player. 30...R4e7 31.Rdd6 Nc5

32.Nc7! Not Rxf6? Nd7! winning the exchange due to the check on e5. 32...Rf8 33.h4 Rff7 34.Nd5 Rd7 35.Rxd7 Nxd7 36.Kg3 Nc5 37.f3

37...h6 38.Nf4 g5?! Black is under pressure due to the slow advance of White on the kingside. This makes it worse though. Needed was to play ...Kh7 and suffer patiently. 39.Nh5+ Kg6 40.f4! gxf4+ 41.exf4 Kh7

42.f5 The slow, patient move is more powerful than capturing on f6 immediately. " The threat is stronger than the execution." - Nimzovich 42...Kg8 43.Kf3 Nd7 44.Ke4 Kf8 45.Rc8+ Ke7 46.Kd5

White is up no material but is completely dominating positionally. 46...b5 47.Rh8 Nb6+ 48.Kc6 Nc4 49.Ra8 Ne5+ 50.Kc5 Nd7+?! Black is losing material in any case, so it was better to try ...Nxg4 Nf4 Ne5 Rxa7+ with at least a few chances. 51.Kxb5 Kd6 52.Rxa7 Rf8 53.Kb4!

53...Nc5 54.Kc4

White has avoided any tricks from the black rook and knight and netted two pawns. Eljanov resigned. 1-0

(3) Carlsen,Magnus - Tiviakov,Sergey [E17]
Crete, 2007

1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.g3 Bb7 5.Bg2 Be7 6.Nc3 Na6 7.0-0 0-0 8.Bf4 Ne4 9.Re1 d5 10.cxd5 exd5 11.Rc1 c5 12.dxc5 Bxc5 13.e3 Nxc3 14.bxc3 Qe7 15.Nd4 Rad8 16.h4 Rfe8 17.Bf1 Ba3 18.Rc2 Nc5 19.Nb5 Ne6 20.Be5 Bc6 21.Nxa3 Qxa3 22.Qg4 Qa4 23.Qxa4 Bxa4 24.Rd2 Nc5 25.Bd4 Rc8 26.Rb2 Rc7 27.Rb4 Bc2 28.c4 Nd3 29.Bxd3 Bxd3 30.cxd5 Rd7 31.Rc1 Rxd5 32.Ra4 Rd7

We have been left with an even material, bishops of opposite color endgame where both sides have two rooks. One may think this should be a simple draw for Black but there are a couple of subtle differences. First, White has a rook on the only really open file. Secondly, White's bishop on d4 is radiating power. Isn't the black bishop very powerful too you ask? Maybe, so Magnus plays to take control of the kingside white squares. 33.g4! h6 34.f3!

Quickly the white king is safe from any mating attacks and the black bishop doesn't look so threatening at all. 34...Kh7 35.Kf2 Ree7 36.Ra3! Bb5 37.Rac3 Magnus makes sure he controls the important file. 37...Rd8 38.Kg3 f6 39.f4 h5 40.g5

Black manages to get some control over the kingside light squares but becomes vulnerable on the dark squares. Note again the power of the white bishop on d4. 40...Kg6 41.Rb1 Rd5 42.Rc8 Be8 43.Rbc1 f5 44.Rb8 Rd6 45.Rcc8 Rde6

The computer may not worry enough about the black position. White has not direct threats, but he has all the active pieces and black's are passive. 46.Be5 Kf7 47.Rd8 Kg6 48.Kf2 Kf7 49.e4!

49...Kg6 ...fxe4 50. Bd6 e3+ 51 Ke1 would win material. 50.Bd6 Rd7 51.Rxd7 Bxd7 52.e5 Bc6 53.Rc8 Be8 54.Ra8

White wins a pawn now. The white bishop had found another powerful spot, now at d6 instead of the earlier d4. 54...Bf7 55.Rxa7 Re8 56.a3 Bd5?! ...Rc8 would have made progress a little more difficult. 57.Ke3 b5 58.Kd4 Bg2

59.e6! Rxe6 60.Be5

The final attack. Note how bishops of opposite color can even attack in the endgame. 60...Kh7 61.Rxg7+ Kh8 62.Re7+ 1-0
