"It is one of the blessings of old friends that you can afford to be stupid with them" – Ralph Waldo Emerson

One of the beautiful things about chess is its authenticity. Your character, style, and emotions are all lay bare in how you play and how you deal with adversity and success within the game. It is a liberating thing to be able to be yourself, as with friends. Over the board, this freedom can also come out when you experiment with a new style or try something innovative to you. I think this what makes the chess club something special. The club provides a venue to live out this experience in play, be it recreational, tournament or simply playing among friends. The joy of sharing moments of authenticity among friends through chess makes the club a venue of cultural, social, and intellectual significance.

Winter TNM Round 2 in Full Swing

Our Winter TNM started round 2 as a refuge from the San Francisco rain. While we had to deal with a glitch in launching the DGT board broadcast on board 1, we continue to stay resilient and ready to try again next Tuesday with success. We posted the standings on Wednesday morning and we have streamlined our processes to get the PGN files and newsletter out in a timely manner. Thank you for your support and patience as we learned to make some adjustments, but you can expect prompt service and support moving forward.

Scholastic Chess News

Our scholastic chess program is developing quite nicely, providing classes to many schools in San Francisco, Burlingame and Hillsborough. In all, we currently run 27 programs, of which, 18 are provided free of charge to schools in San Francisco. The goal of our classes is to inspire chess and promote the critical thinking and social/emotional benefits that chess can offer. We hope that through chess, children can develop skills that will be applicable to many areas of their life in addition to improving their game.

Monthly Rated Scholastic Event

Beginning Saturday April 13, 2019, we will be offering a once a month scholastic rated swiss tournament at West Portal Elementary School. This will give developing younger players an option to engage in rated weekend events in San Francisco to learn, develop their skills, improve their rating and meet new friends. We will also concurrently at this event offer a new event we will call our Junior Mechanic Scholastic (JMS) tournament, which is aimed at brand new players that have never played a rated game. This unrated event will serve as a guide and practice for rated events and children and parents will learn what they need to know to participate in their first rated tournament.

2019 San Francisco Spring Scholastic Championship

Our big 2019 San Francisco Spring Scholastic Championship will take place on Saturday March 23, 2019 and is approaching fast! This event is a celebration of scholastic chess at Golden Gate Park, where there will be a rated open section championship, and an unrated section for grades K-1, 2-3, 4-5, 6-8, 9-12. Best of all, entry for all is free! There will also be a 20-board simultaneous exhibition with GM Daniel Naroditsky. We had about 225 students participate last year and we are looking to have an even bigger turnout this year!

Registration for both the Spring Scholastic Championship and the April scholastic are now open; please visit the club homepage or follow these links:

SF Mechanics Suffer Tough Loss Against Australia

The San Francisco Mechanics PRO Chess League team suffered a defeat on Tuesday to the Australia Kangaroos 11-5. This puts us at 0-2 for the year, but there is still time to mount a comeback in the standings. We have 5 matches remaining, and an additional 3 events called Battle Royale, which pits 8 teams against each other in an all out battle. It is an uphill battle, but I know the Mechanics are good for the fight, especially with the return of GM Sam Shankland, who is currently unavailable as he is playing in the Tata Steel Masters. We will root the Mechanics on next week on Tuesday from the club, as the live broadcast returns to the Mechanics' Institute with IM David Pruess commentating. They will face the Seattle Sluggers, lead by GM Hikaru Nakamura. Play will start at 5:45pm Tuesday, and we will be showing coverage from the big screen inside the club.

Tata Steel Masters at Halfway Point

Many of the best players in the world are currently in Wijk aan Zee, the Netherlands for this 14 player single round robin, including world champion GM Magnus Carlsen, GM Shakhriyar Mamedyarov and our very own GM Sam Shankland. Here is the crosstable for the event:

Play resumes Friday January 18th. For coverage, please visit this link:

Tony Lama's Teasers

Tony pondering over the composition by W.A. Shinkman

28 year Mechanics' Institute security guard and chess enthusiast Tony Lama loves to entertain all comers with his mate in 3 problems, and we thought we would share the same pain in solving them with our readers. We will provide the problem, with the solution coming the next week, along with the next puzzle. The following is the composition for this week:

Wednesday Night Blitz Report

International Master and former MI Chess Club Director John Donaldson made his first appearance in the Wednesday Night Blitz on January 16th and won handily with a score of 10.5 out of 12. Second was Expert Carlos Davila with 9.5 and 3rd was Jules Jelinek with 9. 13 players participated.

A Night of Blitz Magic with the "Magician from Riga".

By Paul Whitehead

In 1991 the 2nd Pan-Pacific International Chess Tournament was held in San Francisco, organized in large part by current M.I. Grandmaster in Residence Nick de Firmian and Mechanics' Institute board members Neil Falconer and Robert Burger. The tournament was held in memory of another M.I. board member, Guthrie "Mac" McClain, and was won by Bobby Fischer's old friend, Grandmaster Eugenio Torre from the Philippines. Of further note is that another, future M.I. board member played as well — Grandmaster Patrick Wolff.

But the star attraction among the invited was the legendary "Magician from Riga", Mikhail Tal.

World Champion in 1960, Tal was the most feared attacking player in the world, a favorite of chess fans everywhere. When Bobby Fischer was coming up, Tal blew him away. He blew EVERYONE away. One might even say that he "smoked" them...

"Mischa" Tal was not a model of healthy living. He drank and smoked, and he was in and out of hospitals for this and that most of his life. Born in 1936, he died in 1993, at the age of only 56.

It was rumored that upon arriving in New York on his way here, he discovered that one cannot smoke on domestic flights in the United States... so he took a flight to Montreal... then an international flight to San Francisco... all so he could continue to puff away uninterruptedly!

So when Tal rolled into the M.I. Chess Club on a rainy night in March of 1991 to play in a big blitz tournament organized by club director Max Wilkerson, we all knew what to expect: smoke and fire. Ashtrays were everywhere, as smoking was strongly encouraged at the time.

The tournament was divided into 2 sections of 18 players — and I got to play Tal! I lost that game, but longtime Mechanics' member Joe Tracy nicked him for a draw — and Joe didn't even smoke!

When the smoke cleared, Tal had won his section, but I was only 1/2 a point behind and finished 2nd. In the other section Berkeley Grandmaster Walter Browne won, and San Francisco Master Richard Lobo finished 2nd. On to the playoffs... Browne and Lobo the non-smokers, Tal and I with ashtrays, lighters and cigarettes at the ready. Who would prevail? I didn't care: I now had the chance to play Tal 2 more games!

On we went, and as Browne squared off with Lobo, I took my chair opposite Tal.

What happened later that night I can only dimly recall: Browne somehow won the event after Tal "played to the gallery" and went down in a blaze of glory, I took 3rd place behind Tal (and drew him a game!) and took 2 friends out to dinner with the $90.00 I won, but...

There was a moment, the highlight of my life in chess, a moment I will never forget, when a hush seemed to fall over the chess room and each spectator seemed to hold their breath, the world stopped and...

Mikhail Tal lit my cigarette.

GM Nick de Firmian Endgame Lab

Master Endgame Play

Kasparov, Spassky, and Fischer were well known for their aggressive play, but they scored many of their points from grinding out a small advantage in the endgame. Karpov, Kramnik and of course Magnus are would purposely choose to enter long endgames with only a minute advantage. However it’s not just recent times where the chess master differentiates himself in the endgame. Emanuel Lasker and the old champions also relied heavily on the final stage of the game. Below we give a classic example from the nineteenth century.

Harry Nelson Pillsbury vs.Isodor Gunsburg, Hastings 1895

1.d4 d5 2.c4 c6 3.e3 g6 4.Nc3 Bg7 5.Nf3 Nf6 6.Bd3 O-O 7.Ne5 dxc4 8.Bxc4 Nd5 9.f4 Be6 10.Qb3 b5 11.Bxd5 Bxd5 12.Nxd5 Qxd5 13.Qxd5 cxd5 14.Nd3 Nd7 15.Bd2 Rfc8 16.Ke2 e6 17.Rhc1 Bf8 18.Rxc8 Rxc8 19.Rc1 Rxc1 20.Bxc1 Bd6 21.Bd2 Kf8 22.Bb4 Ke7 23.Bc5 a6 24.b4 f6 25.g4

The opening and middle game have been quite even, with the great Pillsbury being unable to gain any significant advantage. Black now exchanges on c5, which gives Pillsbury a protected passed pawn on the 5th rank. The small edge White gains is pressed vigorously by Pillsbury in the knight and then king ending.

25...Bxc5?! 26.bxc5 Nb8?! 27.f5!

Threatening 28. Nf4

27...g5 28.Nb4 a5

29.c6! Kd6

White threatened 30. c7 queening the pawn

30.fxe6! Nxc6 31.Nxc6 Kxc6


With this White gets to protect his advance pawn on e6. The black king will be forced to hover around to the e6 pawn preventing it from advancing two steps ahead. Thus the White king is free to roam the board and take the black pawns.

32...dxe4 33.d5+ Kd6 34.Ke3 b4 35.Kxe4 a4 36.Kd4 h5

Gunsburg tries valiantly to get passed pawns on both wings of the board, but White is quicker to the finish line.

37.gxh5 a3 38.Kc4 f5 39.h6 f4 40.h7 1-0
