The Mechanics’ Institute welcomed GM Shakhriyar Mamedyarov for his first visit to our historic club, where along with GM Rauf Mamedov, gave a 26-board simultaneous exhibition that was broadcast via our club’s 10 DGT boards and shown to the world on our Twitch channel and Chess24. The field was quite strong for a simul, as we had 1 GM, 1 IM, 1 FM, and 1 NM, with about 10 other players rated 1800+. It was a tandem simul where the star GM’s had 1:30 in time compared to 45 minutes for the players. The GM’s were not only battling 26 players, but they had to do battle with the clock as well. In the end, the tandem of Mamedyarov/Mamedov amazingly finished 26-0, though Derek Jia had a clear win, but not enough time on the clock to finish. IM Ladia Jirasek was the sole survivor in the end.
Prior to the event, GM Mamedyarov stopped by our broadcast booth/office to do a brief interview. The games started shortly after 7pm, and the race was on. Shakh and Rauf took turns playing the various boards, though it was clear Shakh committed more time to the top boards because of the strength of the competition as part of the overall strategy.
As the field dwindled down to the last few players, attention was focused on 4 games. NM Rui Yang Yan fought hard and kept balance for much of the game, but Mamedyarov capitalized on a weak isolated pawn and built up an advantage over time to take the game. CM Adrian Kondakov held an even position for much of the game and played fighting chess, but was outplayed later on. The drama began with the final two games, where initially GM Mamedyarov sat down against IM Ladia Jirasek and GM Mamedov against Jia. But it became clear that Jia carried the more complex position, so the two GM’s switched seats. Jia had played amazingly well and capitalized on a blunder to have a clear winning game, but only had 15 seconds on his clock with no delay or increment. In the endgame complexity and with little time, Jia blundered away the advantage and lost on time. Jirasek was the final player, and was still in a complex struggle, though a little worse. Once the sole focus was on one game, he was ganged up on by the GM duo and they were able to close the show. It was an amazing event, and all players were given a certificate signed by both players and all score sheets were also signed.
I want to personally thank Judit Sztaray for her amazing organizing of this great event. GM Nick de Firmian and FM Paul Whitehead provided an amazing experience for the viewers in going over the games and communicating the electric atmosphere in the club. Special thanks always to Juan Cendejas for his management of our clubs DGT boards and cameras. We have an amazing team here at our club and it would not have the same quality and experience without the dedicated work of everyone coming together.

What seemed what would be a mellow, normal Monday Night rapid event at the Mechanics’ Institute was bolstered by an afternoon social media push by Judit, who used the “nagging works” philosophy to bring 35 players on July 29th! It was a very strong open section that also featured WGM Carla Heredia, WIM Rochelle Wu, NM Beilin Li, and the clubs very own Jules Jelinek, who manages our Wednesday night blitz event. It was also our first rapid we were able to break out into 2 sections. There were some very dramatic moments in the tournament, including Mechanics regular Felix Rudyak converting a king/rook vs. king/bishop endgame to defeat Carla Heredia and a game in the open section that featured two players simultaneously in check! There were also 5 cases of illegal moves being played, showing the hectic, and unpredictable pace of a rapid event. In the final round, sibling rivalry came to the forefront as Derek and Rochelle were paired against each other with perfect scores. There was no quick draw agreement, as they fought to the end, with Derek securing the win that night and taking sole first with 4-0.

NM Dmitry Vayntrub Registers On Site and Has Perfect 5-0 Score to Take Down the Charles Bagby Memorial
The Bagby Memorial brought a one-day 5 round G/40 event that attracted 36 players. It was an open section tournament won by NM Dmitry Vayntrub with a perfect 5-0, defeating NM Carlos Davila in the final round.
On board 1, NM Dmitry Vayntrub closes the show by defeating NM Carlos Davila to finish clear first with 5/5. WIM Beatriz Marinello came back strong after a tough first round to win an action packed game in the final round against Jamieson Pryor to tie for 2nd

Ever wonder what's the difference between the supplemental and actual rating? what's the difference between regular, quick and blitz rating? Pretty simple, just need to know the key numbers :)
Actual rating is the rating that is changing after every rated game, after every rated tournament. This can be checked at the last page of everyone's uscf page.
Supplemental rating is a rating that is determined for each player on the third Wednesday of a month, by taking a snapshot, or freeze, of the rating, and it is used for the following month, for the entire duration of the month. It's also called monthly (supplemental) rating. Any player must have at least 4 rated games in order to have a supplemental rating. Most tournaments use supplemental ratings when running tournaments.
There are three rating systems: Regular (slow), Quick (fast) and Blitz.
Regular rating system is used, and hence regular rating is affected, if the playing time for each player is greater than 65 minutes.
Quick rating system is used, and hence quick rating is affected, if the total playing time for each player is more than 10 minutes, but less than 30 minutes.
A game is dual rated, both regular and quick rating is affected, when the total playing time for each player is between 30 and 65 minutes.
Finally, blitz rating system is used, and hence blitz rating is affected, if the total playing time for each player is between 5 and 10 minutes.
Of course there are other fine prints in the regulations, but the main guidelines are based on the time controls. More details in the USCF rule book 5C. part, read it here:
How can the total playing times be calculated? Take the time control: G/minutes and inc/seconds or d/seconds: total time equals minutes plus (seconds times 60) or minutes+seconds.
For example: our common time controls: G/120 d5 = 120+5 = 125 minutes, G/40 d5 = 40+5 = 45, G/15 +2s = 15+2 = 17.
Keep in mind all above mentioned details are USCF rules & regulations. FIDE is a whole other story :)
In FIDE, besides having to pre-register the tournament in advance, otherwise it won't get rated, here are the relevant rules:
A tournament is regular rated if it has the following conditions:
- are players rated 2200 or higher in the tournament? --> each player must have at least 120 minutes,
- are players rated 1600 or higher in the tournament? --> each player must have at least 90 minutes;
- are players rated below 1600 only in the tournament? --> each player must have at least 60 minutes;
This can explain why the upcoming Smith memorial tournament is FIDE regular rated, yet only have G/90 d5 time control --> becuase we limit the players under2200.
Rapid system is used if each player has more than 10 minutes, but less than 60 minutes.
Finally, blitz rating sistem is used when the total playing time for each player is between 5 - 10 minutes.
Detailed information here: https://www.fide.com/fide/handbook.html?id=197&view=article

By FM Paul Whitehead.
Hundreds of thousands, if not millions, of chess books have been written, good and bad. Every serious chess player has a library of books, and there are many lists of “desert island” chess book collections: those deemed indispensable by this writer and that. I have my own top 10 list, subjective of course, and my reasons for including these books I will try to explain. Beware, however: these books are old, and some can only be found in English descriptive notation. Furthermore, if you are looking for modern opening theory, you will have to go elsewhere. Yet I believe these ten books can be a foundation for a “classical” chess education: they were for me, and they played a vital role in my chess development. Each in its own way imparted a deep love for the game, and I found a rich knowledge therein as well. I hope you enjoy this list, and maybe it will help you to start thinking of what chess books mean to you.
1. Paul Morphy and the Golden Age of Chess, by William Ewart Napier (1934).
This was my first chess book. As an introduction to the chess masters of old, and the beauty to be found in their games, I think it’s a classic. The games are famous, obscure, extraordinary. If the title doesn’t whet your appetite, then the 59 chapters with titles like “Gambit Dessert”, “Pillsbury and the Incomparable Twins”, “Zuckertort’s Immortals”, and “Chess Caviar” most surely will. The games are very lightly annotated, if at all, but the best part for me are the pithy and learned introductions to each game, for example here to Janowski vs. Schlechter, Vienna Congress 1898:
“Chess is not for the languid. Schlechter had many apathetic days. At the start of the following game there is balance; but Janowski in this fine ending, shows that it is not a self-maintaining state.”
2. Modern Chess Openings 10th Edition, by GM Larry Evans & Walter Korn (1965).
With apologies to my friend and colleague GM Nick de Firmian (who has been the editor of MCO since 1988), this edition is the one that I and many players who grew up in the Fischer era broke our teeth on, and therefore my favorite. There have been many imitators, including NCO (Nunn’s Chess Openings) and BCO (Batsford Chess Openings, Kasparov), but the Evans edited 10th edition remains (for me) the greatest single-volume opening book ever written - because I would never read another opening book!
3. Fischer/Spassky: The New York Times Report on the Match of the Century, (1972).
Multiple contributors, including I.A. Horowitz, GM Samuel Reshevsky and Harold C. Schonberg, give a fascinating kaleidoscope of likely the most famous chess match that will ever be held. The book was rushed into print after the match, yet perfectly conveys the excitement and drama of this Cold War battle. Schonberg’s purplish prose lifts this gem of a book, and chess itself, to fantastic heights. Here he is at one point, on Fischer:
“And mingled with all the anger and resentment was a curious undercurrent of sadness that so great and indeed, so creative, a chess mind should have acted in such a fashion.”
Other books came out on the match, but for me this is the all-time classic.
4. Think Like a Grandmaster, by Alexander Kotov (1971).
True, I never became a Grandmaster, but at least there was a book out that pointed the way! This book has a lot of great practical advice for chess improvement, such as when to trust your opponent or not, how to handle time-trouble and blind-spots. There is also a discussion of “candidate moves” and great advice on how to study chess. Before reading this book, I paid more attention to my intuition and feeling for a position, but afterwards my play became a little more concrete. The Art of the Middle Game, Keres & Kotov (1964) is another book that I strongly recommend, and is a sort of companion book to Think Like a Grandmaster. Both teach that the road to chess-mastery is not easy and requires intense study and practice!
5. Chess Endings: Essential Knowledge, Yuri Averbakh (1966).
I am often asked about endgame books, or how to study the endgame. Back in the day, we had Reuben Fine’s classic Basic Chess Endings, (1941) as a reference. The more ambitious of us would study Rook Endings, by Levenfish & Smyslov (1971), or even the daunting Pawn Endings, by Averbakh and Maizelis (1974). Nowadays people swear by Mark Dvoretsky’s Endgame Manual, (2003).
My approach, and the advice I give to my students, is more practical, I think: learn and understand the terms Zugzwang and the Opposition. Centralize your king. Learn the essential endings like the basic mates, and K+P vs K. Then learn a couple more: the Lucena Position and the 3rd Rank defense in rook endings. When playing over the notes and games of the great players, watch how they play the endgame. Take an interest in endgame studies: some of the most beautiful “chess art” is there. Take apart and analyze your own games: they hold the richest keys to your improvement.
GM Yuri Averbakh’s book, at 135 pages, has all you need to get started. Don’t fear the endgame: get some essential knowledge, and take it from there.

Next Scholastic Tournament
Swiss & Blitz
Aug 24 @ MI
Next tournament is on Saturday, August 24th, and since most of the kids will be back to school already, I expect it to be full house. I encourage everyone to register early, and secure your spot. NEW in August is the quick and fun blitz right after the Swiss! So grab some lunch after Swiss and come back to play a fast and fun blitz touranemnt between 3-5PM.
Blitz is a fast time control game, with Game in 5 minutes no delay, so one game can last up to 10 minutes. We'll play 4 double rounds: that means when we paid, kids will first play as they are paired, and immediately after they will play a second game with the same opponent, just switching the colors. So any player will play both white and black against the same opponent in each round.

Nick de Firmian's Column - Magnificent Magnus
Week 1 – endgames
We have nine weeks of the Summer TNM (Steve Brandwein Memorial). For each week we will investigate games and positions from the highest rated player of all time. There is so much to learn from Magnus, even though he is only 28 years old. He has already been the highest rated player in the world for 9 years, since he was 19. He is able to handle all types of positions – attacks, defense, strategic games, wild opposite sides castling. What set him apart from an early age though was his endgame play – far and away better than any young player of his generation. One must compare him to Capablanca and Karpov in that regard, but the success Magnus has had winning minute advantages (or drawing miserable positions) probably makes him the number one all time endgame master. We start this week with a few of his classic endgames.
(1) Vallejo Pons,Francisco - Carlsen,Magnus
1.e4 d6 2.d4 Nf6 3.Nc3 e5 4.dxe5 dxe5 5.Qxd8+ Kxd8 6.Nf3 Bd6 7.Bg5 Be6 8.0-0-0 Nbd7 9.Nb5 Ke7 10.Nxd6 cxd6 11.Bb5 Rhd8 12.Nd2 h6 13.Bh4 g5 14.Bg3 a6 15.Bxd7 Rxd7 16.f3 Rc8
The opening went quickly into an even endgame. Magnus has black against a 2700 player and many old school people would expect a quick draw. 17.Kb1 Nh5 18.Nf1 f5 19.exf5 Bxf5 20.Ne3 Bg6 21.Rd2 Ke6 22.b3 b5 23.Kb2 d5!
The exclamation mark is for courage! Magnus advances in the center in this now complex endgame. The black king is in the middle where it is exposed to the attack of the white rooks. That danger must be respected. 24.Re1 Nxg3 25.hxg3 h5 26.c3 d4! 27.cxd4 Rxd4 28.Rxd4 exd4
Magnus allows a discovered check. It was important that he exchanged a pair of rooks so that White would not have a strong attack on the black king. 29.Nc2+ Kd5 30.Nb4+ Kd6 31.Rc1?
Vallejo Pons is afraid of the black rook coming to c2 and decides to trade rooks. He needed to stay strong under pressure and play 31. Rd1!. Now Magnus shows the power of bishop against knight. 31...Rxc1 32.Kxc1 h4!
So that the black bishop can pick up the g pawn after 32. Nxa6 Bd3 33. Kd2 Bf1, giving Black a killer passed h pawn. 33.gxh4 gxh4 34.Nxa6 Best, as 34...a5 was coming. 34...Bd3 35.Nb4 Bf1 36.Kd2 Bxg2 37.Ke2 Bh3! 38.a4
38...Bf5! 39.axb5 d3+!
With only two pawns left, Magnus stretches the capacity of the white king and knight beyond their limits. 40.Ke3 h3 41.Nxd3 Bxd3
White resigns as 41. Kf2 Bf5 allows the black king time to mop up the pawns. 0-1
(2) Radjabov,Teimour - Carlsen,Magnus
Candidates Tournament, 2013
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 d6 5.Nf3 Nbd7 6.g3 0-0 7.Bg2 e5 8.0-0 c6 9.Rd1 Re8 10.dxe5 dxe5 11.a3 Bxc3 12.Qxc3 Qe7 13.b4 Nb6 14.Be3 Ng4 15.Nd2 f5 16.h3 Nxe3 17.Qxe3 e4 18.Rac1 Be6 19.Qc3 Rad8 20.Bf1 c5 21.bxc5 Na4 22.Qb4 Nxc5 23.Nb3 Rxd1 24.Rxd1 Na6 25.Qxe7 Rxe7 26.e3 Kf7 27.Be2 b6 28.Rd8 Nc5 29.Nd4 Kf6 30.Kf1 Rd7 31.Rf8+ Bf7 32.Ke1 g6 33.h4 h6 34.Rc8 Be6 35.Rf8+ Rf7 36.Rh8 Rc7 37.Nb5 Rd7 38.Nd4 h5 39.Rf8+ Bf7 40.Rc8 Ke5 41.Ra8 a6 42.Rc8 Rd6 43.Nc6+ Kf6 44.Nd4 Be6 45.Rf8+ Ke7 46.Ra8 Rd7 47.Rb8 Rb7 48.Rxb7+ Nxb7 49.Kd2 Kd6 50.Kc3 Bf7 51.Nb3 Ke5 52.Bf1 a5 53.Be2 Be6 54.Bf1 Bd7 55.Be2 Ba4 56.Nd4 Nc5 57.Kb2 Be8 58.Kc3 Bf7 59.Nc6+ Kd6 60.Nd4 Nd7 61.Nb5+ Kc5 62.Nd4 Ne5 63.Nb3+ Kc6 64.a4?!
Thus far the game has been quite boring. The solid Radjabov has gotten a very equal ending with White and Magnus has not made any progress. He has been patient though, and White has now made a slight error, putting the a pawn on a white square. 64...Kd7 65.Nd4 Kd6 66.Nb5+ Kc5 67.Nd4 Be8 68.Nb3+ Kd6 69.c5+ Kc7! 70.Kd4 Nc6+ 71.Kc3 Ne7 72.cxb6+ Kxb6 73.Nd2 Bxa4 74.Nc4+ Ka6! 75.Na3+ Ka7
Black has an extra pawn, even though it is in danger. Now 76. Nc4 Bb5! creates an unpleasant pin. 76.Kd4 Nc6+ 77.Kc5 Ne5 78.Nc4? White is afraid of 78. Kd4 Nd3 79. Bxd3 cxd3 80. Kxd3 when Black has a bishop and (now) strong a pawn. Yet this was better. 78...Nd3+ 79.Kd4
79...Nc1! 80.Bf1 Bb5!
This unexpected pin is lethal. White has no good way to untangle and tries to sweep up all the black pawns. 81.Nxa5 Bxf1 82.Nc6+ Kb6 83.Ne7 Nd3 84.Nxg6 Kc7! 85.Ne7 Bh3 86.Nd5+ Kd6 87.Nf6 Bg4!
Radjabov resigned here. This game was an amazing case of making something from nothing. 0-1
(3) Kramnik,Vladimir - Carlsen,Magnus
1.d4 d5 2.c4 Nc6 3.Nf3 Bg4 4.Nc3 e6 5.Bf4 Bd6 6.Bg3 Nf6 7.e3 0-0 8.a3 Ne7 9.Qb3 b6 10.Ne5 c5 11.Nxg4 Nxg4 12.Rd1 Bxg3 13.hxg3 Nf6 14.cxd5 exd5 15.Be2 Qd6 16.Qc2 h6 17.0-0 c4 18.b3 Qxa3 19.bxc4 dxc4 20.Bf3 Rab8 21.Ra1 Qd6 22.Nb5 Qd7 23.Qxc4 a5 24.e4 Rfc8 25.Qe2 Rc6 26.Rab1 Rd8 27.Rfd1 Rdc8 28.d5 Rc2 29.Qe3 R2c5 30.Nd4 Re8 31.Qd3 Qd6 32.Qa6 Rb8 33.Nb3 Rc2 34.Nd4 Rc5 35.Nb3 Rc2 36.Qd3 Rcc8 37.Nd2 Ng6 38.Be2 Qc5 39.Rb5 Qc3 40.f4 a4 41.e5 Nd7 42.Qxc3 Rxc3 43.Ne4 Rc7 44.Ra1 Ra7 45.d6 Ngf8 46.Nc3 Nc5 47.Nd5 Ra5 48.Rxb6 Rxb6 49.Nxb6 Nfe6 50.Bc4 Kf8 51.f5 Nd8 52.Rf1 Ncb7 53.Re1 a3 54.e6 fxe6 55.fxe6
Thus far the game has been a tour de force by the great champion Kramnik. Magnus was still a teenager at this stage and he is certainly lost. However, he doesn't give up and takes his best chance. 55...Nxd6! 56.e7+ Ke8 57.exd8Q+ Kxd8 58.Rd1 Kc7 59.Ba2! Rg5 60.Nd5+ Kc6 61.Nc3 Rc5 62.Rxd6+ Kxd6 63.Ne4+ Kc6 64.Nxc5 Kxc5
So Kramnik has an extra bishop for a pawn. Yes it is winning, but Magnus has a little to work with to make it difficult - the better king and the advanced a pawn. 65.Kf2 Kd4 66.Kf3 Kd3 67.g4 Kd2 68.Be6 Kd3
69.Kg3?! 69. g5! hxg5 70. Kg4 would win, but Kramnik was afraid of trading pawns. 69...Ke3 70.Kh4? Kf2!
Now Magnus can make enough trouble to draw. 71.Bd5 g6 72.Kh3 g5! 73.Kh2 Kf1 74.Be6 Kf2 75.Bc4 Ke3 76.Kg3 Kd4! 77.Be6 Ke3 78.Kh2 Kf2 79.Bc4 Ke3 80.Kg1 Kf4 81.Be6 Ke5 82.Bb3 Kf4 83.Be6 Ke5 84.Bb3 Kf4 85.Be6 Ke5 86.Bb3
Draw ageed as the white bishop must both defend the g pawn and stop the a pawn. An amazing escape! 1/2-1/2

(1) Stearman,Josiah P (2427) - Ostrovsky,Sergey (2032) [C55]
MI Brandwein TNM: 2000+ San Francisco (1.1), 06.08.2019

This break leads to trouble. Better to just develop with Qd7. 13.axb5 dxe4 14.bxc6 exf3 15.Nc4! Nd5?! 16.Qxf3 f6?! Black needed to take a white pawn on g2 or then c3 to break up the nice white structure. Now the game is firmly in White's control. 17.Bd2 Nb6 18.Nxb6 cxb6 19.d4! exd4 20.cxd4 Qxd4 21.Bc3

A classic postion first seen in the Spassky - Fischer World Championship match 1972. Both Michael and Eric head straight into the complications. 12...b4 13.Nd5 exd5 14.exd5 14. e5 is a worthly alternative. 14...Kd8 15.Rxe7!? Kxe7 16.Nf5+ Kd8
17.Nxg7? This seems wrong. [Using the pins with 17.Bh4 Rg8 18.Nh6! would keep the game unclear.] 17...Kc8 18.Bf5 Kb8! 19.Qh3 h6 20.Ne6
White is rather desperate here. This isn't enough compensation for the rook. 20...fxe6 21.dxe6 Be4?! 22.Bxe4 Nxe4 23.exd7 Nxg5 24.fxg5 Ra7 25.g6 Qxd7 26.Qg3 Qe7 27.h4 Qe5 28.Qf2 Qc5 29.Qe2 Rc8 30.Rd3 Rac7 31.c3 bxc3 32.Rxc3 Qe5 33.Qxe5 dxe5 34.g4 Rxc3+ 35.bxc3 Kc7 0-1

28.Qa5? White should trade queens and take on c6 with good chances to win the endgame. Now Black gets attacking chances. 28...Rb2! 29.Qc7 Rxg2+! 30.Kxg2 Qf1+ 31.Kh2 Qf2+ 32.Kh3?? Kh1 would just be a draw. 32...Bf1+ 33.Kg4 Be2+ 34.Kg5 Qxg3+ 35.Kf6 Qxh4# 0-1
