Big Upset Highlights Round 3 of the TNM

A big upset and survival mode in the championship section were front and center during round 3 of the Fall TNM. Board 1 saw a hard fought draw between NM Eric Yuhan Li and NM Michael Walder. Walder continues to perform very strong after last week's upset of FM Kyron Griffith. On board 2, NM Russell Wong defeated Ethan Boldi. Board 3 saw a draw between Steffen Thieme and NM Larry Snyder, where it looked like Thieme was able to take advantage of Snyder's 1 second remaining on the clock to get a draw agreed to in what was a winning position for Snyder in a rook and pawn ending. However, not much looks clear with a second remaining and at least a half point was preserved. The news of the round occurred on board 5, where Kristian Clemens (1956) came back from a losing position and took advantage of a blunder (27. g6+) to go from 3.02 losing to 3.35 winning. He was able to successfully convert the ensuing ending to seal his first ever victory over an IM. 

Kristian Clemens (black) used luck and skill to upset IM Elliott Winslow

What made this move interesting was that FM Kyron Griffith and FM Paul Whitehead had both calculated this line with 27. g6+, thinking Qxg6 and then 28. Rh5+ winning the queen. What they both missed, and Elliott as well, was that Clemens plays 27... Qxg6 with check! This was a blind spot that was missed by everyone, and told the tale of the match.

In the AB section, Jonah Busch and Robert Drane are the only perfect scores with 3/3 and will almost certainly face off next week. these are two strong A/B players who frequently are among the leaders in previous TNM's so this will be a great match to follow next week. 

In the very competitive under 1600 section, we have 3 players with a perfect score; Albert Starr, Michael Martin, and Illia Gimelfarb. Many strong players lurk at 2.5, including Venugopal Mani, whose half point was the result of a bye. There are still many rounds to go, so there is plenty of time for redemption and making a push up the leaderboard. 

The TNM also had a very special visit from the Mongolian women's national team. They were stopping by the Bay Area for a few days on their way to Los Angeles. They stopped by in the annex to play blitz and checked out some of the action of the TNM. This team included several WFM's and a WIM. Thank you to WFM and Mechanics' coach Mugi Tsegmed for making the visit possible!

GM Susan Polgar's visit to Mechanics' Institute Chess Club

Let me start this report by thanking this amazing chess community. Your support has been warming in the past month's and year, but Saturday evening it showed in the form of helping us welcome GM Susan Polgar with a full house! you all for coming and attending her event!

GM Susan Polgar started her visit with an interesting, and fun game that she played against women's world champion GM Maia Chiburdanidze at the Calvia Olympiad 2004. She went over the crucial elements of her game, and the interacive lecture was visibly engaging and enjoybale for all.

After the game review, Susan took some interesting, fun and sometimes surprising questions. Among those were the usual "What's your favorite opening?" or "Did Bobby Fischer propose to you?" Happy we had time for quite a few questions, we hope that all of you got to enjoy the answers.

As the last step of the visit, we had Susan's signature 20 piece puzzle competition. Many of the players stayed and enjoyed the 30-minute challenge. Top 5 scorers are encouraged to come and pick up a book from our office as a reward for their amazing performance! Here are the results:

This link also has the pdf for the puzzles, so please check it out and attempt!

Tournament Director's Corner
Illegal move - in FIDE tournaments


Tuesday Night Marathon has long been FIDE rated. When the tournament was changed from an Open, one section, to a three section setup, all three sections were kept FIDE rated.
This means that standard FIDE rules apply in situations. This week we are covering the illegal move case.
What happens if a player makes an illegal move in a FIDE rated game? Opponent should pause the clock, and get the tournament director. The position immediately before the illegal move shall be reinstated (7.5.1), and TD will be adjusting the clock: adding 2 minutes to the opponent's time (7.5.5). Second time the same player makes an illegal move in the same game, the game will be declared lost by the player who completed the second illegal move.

Interesting situations that are considered illegal moves:
- if a player uses two hands to complete one single move (castling for example);
- pressing the clock without moving;
- if a player moved a pawn to the furtherst rank, pressed the clock, but not replaced the pawn with a new piece (promotion was not completed.)

Hope this helps any and all players to be confident when calling out illegal moves. And it is also good for the tournament directors to review these rules often, so that the correct ruling can be made even at late hours of the day.

FM Kyron Grifith Dominant in Carroll Capps Memorial

The 48th Carroll Capps Memorial was held November 2-3. It was a 2-section event with a time control of G/90 +30, with both sections FIDE rated. In the 1800+ section FM Fyron Griffith scored a perfect 4-0. Griffith's toughest challenge came in round 3 against IM Elliott Winslow. However, he was able to grind out a win en route to sole first. Theo Biyiasas and Daniel Lin tied for second with 3/4. In the under 1800 section, Romeo Barreyro and Adam Culbreth scored 3.5/4 to tie for first. Taking sole third was Mechanics' regular Albert Starr. Congratulations to all the winners.

FM Kyron Griffith (white) faces off against IM Elliott Winslow on board 1, while Aksithi Eswaran and Theo Biyiasas do battle on board 2.

In memoriam, Paul Allen Gallegos (October 10, 1963 – October 31, 2019)

by Cesar B. Tamondong, Jr.

Life Master Paul Gallegos peacefully passed in the early morning of October 31, 2019 due to complications from Dyskeratois Congentia, resulting in the rejection of his lung transplant.  Paul leaves behind his wife Susan and children Michael and Megan, stepchildren Ryan and Tara; mother Barbara and brother Daniel. He also has two sisters, Chris and Joanna.

            Paul worked as a teacher in the Santa Rosa school district as a physical education teacher and principal for over 20 years and had resumed an active tournament schedule after retiring from teaching.  Paul helped coach several scholastic teams and was recognized for his efforts by the San Francisco Unified School District.  Along with tournament chess, Paul was a black belt in karate; enjoyed traveling with his wife, Susan and spending time with friends and family.

            Paul held the USCF Life Master title and had a peak FIDE rating of 2148, with consistent results in local and national tournaments.  Paul’s game against GM Timur Gareyev in the 2010 U.S. Open in Irvine, California was featured in John Shaw’s 2013 book, “The King’s Gambit” – Quality Chess (Paperback ISBN 978-1-906552-71-8 Hardcover ISBN 978-1-906552-74-9).  I will provide an abridged annotation from Shaw’s book of Paul’s draw against GM Garyev in game he was winning, drawing in a tough ending.

            Paul will be remembered in the chess community as a true gentleman master, taking the time to analyze with all opponents, lend a friendly ear and laugh.  Paul always had an easy smile, kind word and positive outlook on life.  As a teacher in Santa Rosa, he had the same impact among students and the community.

My last memory of Paul will be his emails and text messages, coaching me during the 2019 Western States’ Open Chess Tournament in Reno, Nevada.  Before my final round game, Paul emailed me, imploring me to start playing the Queen’s Gambit Declined, Exchange Variation instead of the Catalan to generate more winning chances.  I followed his advice and won my 6th round game.  We last spoke on October 21, 2019, after I returned from the Reno tournament and planned on meeting up in Santa Rosa in early November to prepare for my next tournament.  It is my hope we organize a tournament in 2020 in honor of Paul Gallegos – beloved husband, father, teacher and friend who will be missed by all whose lives were touched by his indomitable energy and kindness.

            Memorial services will be on November 16, 2019, 1:30 p.m. at Saint Dunstan’s Church; 1133 Broadway Avenue; Milbrae, California 94030.  You may send condolences to Mrs. Susan Gallegos; 196 El Encano Way; Santa Rosa, California 95409.


Remembering NM Paul Gallegos
by Aaron Thompson

As a National Master, someone with a black belt in karate, and a role model for physical fitness, Paul Gallegos was a Renaissance man. When I first met him in 2013, he was my middle school gym teacher. I had played in three rated tournaments before meeting Paul but I did not intend nor know how to break that barrier from casual to competitive play. We talked about chess during our lunchtime chess club and chatted before and after class. Those conversations gave me the passion for chess that will last a lifetime. When “Mr. Gallegos” finished playing one of his best events (FM Eric Shiller Schiller Championship in 2014), he told me about it after I ran a mile in his gym class. You can only imagine how motivating it was to hear him talk so casually about beating master after master!

As many chess players in our community can attest, Paul was never one to mince words. The directness with which he spoke helped me to improve quickly. Cutting the fat out of chess play and offering sound advice really does something for a player. I remember when I told him super excitedly before class that I had a refutation for 1. Nf3 Nf6 which was to play 2. g4. I was looking at him and waiting for his praise but instead he turned to me and said, “What are you talking about? I can just take the pawn for free”. At the time, it hurt, but making direct points like that is the best way to improve and reach one’s goals. At the end of the day, bad moves are bad and good moves are good.

I can go on and on and on with little vignettes about our shared experiences through the years but I would be remiss if I didn’t acknowledge Paul’s stature in our chess community. In the last tournament we played together, 2019 Stamer Memorial, I overhead two players as they spoke in hushed tones: “Is Gallegos coming?” “Yeah, I saw him on the pre-reg list” and I will always think of Paul as a chess icon. To me, Paul was always so cool. In his humble presentation, composure, and discipline, backed up with consistently stellar chess play it was hard to not want to be around him. He played arguably one of the most famous King’s Gambits of all time too, and I didn’t even know about it until recently.

I hope that everyone can take a little bit of Paul with them as they pursue their goals. Whether it is in trying to reach new heights in something specific like chess, or something broad like being a better person, we all have wings. Paul’s wings are just a little bit different now.

I’m going to miss you so much!

A Classic Game From NM Paul Gallegos

Cesar Tamondong, Annotations by GM John Shaw

(215) Gallegos,Paul (2102) - Gareyev,Timur (2614) [C30]
US op 111th Irvine (3), 05.08.2010
[GM John Shaw, The King's Gambit Quality Chess]

Annotation notes courtesy of GM John Shaw's book, "The King's Gambit", Quality Chess 2013. GM Shaw has extensive notes Paul's Game, it's Game 55 in Shaw's book. Notes from Shaw's book are followed by "(Shaw)" and My notes are followed by "(CT)". Scottish GM John Shaw's, "The King's' Gambit" is a 680 page volume devoted to the King's Gambit - a well-received book released by Quality Chess in 2013. During a lesson with Paul in November 2018, he told me in early 2011, GM Shaw emailed him, asking if could feature this game in his Kings' Gambit book. Paul agreed and provided notes. On a side note, this was the first tournament game, Paul's wife, Susan had seen him play. After coming back from lunch, Susan was looking for Paul since she thought he would be done with his game, and to her surprise, she saw over 50 plus people straining to see this game. According to Paul and others who were watching the game, the TDs had to cordon off Paul's board since a sizeable crowd had gathers, akin to waiting for an upset! Shaw devotes over 6 pages of detailed analysis to Paul's game, so if you have a chance to check out the Shaw book, the additional annotations by Shaw do justice to a game which Paul considered one of his best! (CT) 1.e4 e5 2.f4 Bc5 3.Nf3 d6 4.Nc3 Nf6 5.Bc4 Nc6 6.d3 Ng4!? This may appear scary, but if White is well prepared he should be happy to see this premature jump. (Shaw) 7.Ng5! 0-0


Position after ...7. O-O. This has been Black's usual choice, but it may not be best. (Shaw) 8.f5 Bf2+ 9.Kf1 Ne3+ The only sensible try. (Shaw) 10.Bxe3 Bxe3 11.h4


Position after 11. h4. White should avoid retreating if at all possible. 11...g6 12.Qg4 Ne7? 13.Qf3! An easy move to miss. The queen jas just moved from d1 to g4, so can a step back really be so devastating? Yes, it can. (Shaw) 13...Bxg5 [Any bishop retreat, say 13...Bd4 , is crunched by 14.Nxf7 Rxf7 15.fxg6; Black could have tried to confuse the issue with 13...d5 , but after 14.f6 dxc4 15.fxe7 Qxe7 16.Qxe3 White's extra piece will decide the outcome. (Shaw)] 14.hxg5 Nxf5 [Wholly justified deparation, as White was threatening a variety of mating attacks along the h-file. Just one example: 14...c6 15.fxg6 hxg6 16.Qf6 (Shaw)] 15.exf5 Qxg5 16.fxg6 hxg6 17.Ne4 [17.Kg1 planning Rf1 was even more convincing, but White is winning every which way. (Shaw)] 17...Qf5 18.Qxf5 Bxf5 19.g4 Bxe4 20.dxe4 Kg7 21.Ke2 f6 Black has stabilized his kingside, but White's extra piece should obviously be enough to decide the game. For a white! For a while it all goes fine. (Shaw) 22.Rh2 Rh8 23.Rah1 Rxh2+ 24.Rxh2 c6 25.Kf3 Rd8 26.Rd2 f5! Black's only chance is to give up a pawn in order to get his centre moving. (Shaw) 27.gxf5 gxf5 28.exf5 d5 29.Bf1 [Not bad, but 29.Bb3 , planning c2-c4 was more to the point. Note that 29...b5 weakens c6 and so is hit by 30.Rg2+ and 30...Kf6 31.Rg6+ (Shaw)] 29...Kf6 30.Bh3 Rh8 31.Kg3 e4 32.Rh2 Kg5 33.Bg4 Rxh2 34.Kxh2 d4 35.Kg2 [Not chosing 35.Kg3 is a little eccentric, but no harm has been done yet.] 35...c5 36.Kf2 b5 37.Ke2 [The text move spoils nothng, but White fails to find the quickest winning idea. He needs to get his king in among the black pawns and that means playing Kf4. The quickest path is to sacrifice the f5-pawn. As long as White realizes Kf4 is essential then everything should run like clockwork. For example: 37.c3!? b4 38.cxd4 cxd4 39.Kg3 a5 40.f6! Kxf6 41.Kf4 e3 42.Ke4+- (Shaw)] 37...a5 38.a3 [38.c3 still works of course. (Shaw)] 38...Kf6 39.Kd2 b4 40.axb4 axb4 41.b3 Kg5 42.Bh3 Kf6 43.Ke2 Ke5


Position after ...43. Ke5. Several hours of exhaustive play, Paul plays the only move that draws. (CT) Paul had presented this endgame during one of our lessons. (CT) 44.Kf2?? [A step too far. White could have won with 44.Bg4 Now the bishop helps stop the pawns and the king is free to step forward, for instance: 44...Kf6 45.Kf2 Kf7 46.Kg3 e3 47.Kf4 Ke7 48.Ke5+- (Shaw)] 44...c4!= Absolutely securing the draw. (Shaw) 45.Ke2 [45.bxc4 is still a draw, but only after both sides find a series of only moves. 45...d3[] 46.cxd3[] b3[] 47.d4+[] Kxd4[] (47...Kf6?? 48.Bg2! Kxf5 49.Ke3+-) 48.f6[] b2[] 49.f7[] b1Q[] 50.f8Q[]= I do like the 'box' sign. In addition, to the likelyhood of a perpetual, Black can kill the final white pawn. (Shaw)] 45...c3 [Considering the way the game was going, it was worth trying 45...d3+!? After the likely 46.cxd3 cxb3 a horrible accident is possible: 47.Kd2?? (47.Kd1= is just one of the drawing moves (Shaw)) 47...e3+-+] 46.Bg4 "The disappointing ending should not obscure the fact that a 2100 player was crushing a 2600 with the King's Gambit. I doubt that this would have happened in a main line Spanish." (Shaw) We will miss Paul's energetic personality and style. Rest in Peace my friend. (CT) 1/2-1/2

GM Nick de Firmian's Column

Great Women Chess Players:  Week 2 - Nona Gaprindashvilli


Nona Gaprindashvilli comes from chess centered Georgia, a country with great respect for the Royal Game. Only last year (2018) Georgia hosted the epic Chess Olympiad in the city of Batumi. This former Soviet country has a good number of chess grandmasters, but the curious fact is that Georgia had the world’s best women chess players in the 1950s through 1980s.

Nona can be regarded as the first woman to break through the barriers of male dominated chess. She is the first to gain the (men’s) Grandmaster title, back in 1978. One must note that in those days that title was rarer and harder to come by. Thus all chess players, men and women had great respect for her play. Well, almost all. There was one very confident individual that thought women simply can’t play chess (he had the usual machismo reasons in those days). He said he would beat Nona in a match at knight odds! This individual was none other than Bobby Fischer, and as good as he was the boast was simply ridiculous. When Nona quickly accepted the challenge Bobby never said another word on the matter.

Nona has an appealing, aggressive style. She is a three-time Women’s World Champion, several times part of the Olympiad Champion Soviet Women’s teams in which she won nine gold medals (individual or team). She also won international tournaments where almost all players were men.


(1) Nona Gaprindashvili - Rudolf Servaty [B39]

This variation was popular at one time, but White's next move was found to put Black under pressure. 10.Nb5! 0-0 11.Be2 Qh4?! [11...Qa5+ Is a better try for equality.] 12.Nxd4! exd4 13.Bxd4 Qxe4 14.Bxg7 Qxg2

15.Qd4! Qxh1+ 16.Kd2 Qxa1?

[16...Qxh2 17.Bf3 d5 18.Bxf8 Kxf8 19.Rh1 Qd6 20.Rxh7] 17.Qf6!



(2) Nona Gaprindashvili - Juraj Nikolac [B19]

[17...Nxe5 18.Bxe5 0-0 Is just a little better for White.] 18.Nf5! Rfe8

19.Nxg7! Kxg7

20.Bxh6+! Kxh6 [20...Kg8 21.Re3 Nxe5 22.dxe5 Nxh5 23.Qe2 Ng7 24.Bxg7 Kxg7 25.Qh5 Would win.] 21.Nxf7+ Kxh5

22.g4+! Kh4 [22...Kxg4 23.Qg6+; 22...Nxg4 23.Qh7+] 23.f3 Nxg4 [23...Qc7 24.Re5! Cuts off the black queen.] 24.Re4



(3) Judit Polgar - Nona Gaprindashvili [C43]
Chess Olympiad (Women) Novi Sad YUG, 1990

This game was played while Judit was a teenager and not yet at her peak. Nona at this time was past her prime, but still extremely strong. An interesting battle of generations. 1.e4 e5 2.Nf3 Nf6 3.d4 Nxe4 4.Bd3 d5 5.Nxe5 Nd7 6.Nxd7 Bxd7 7.0-0 Qh4 8.c4 0-0-0

This double eged position is a Petroff Defense! Both players go for the win, making the solid opening into a sharp battleground. 9.c5 g5!? 10.Nc3 Bg7 11.Ne2?! [11.g3! Asking where the queen goes is likely a better choice.] 11...Rhe8 12.Qe1 Nf6 13.Qd2 Ne4 14.Qa5 [14.Bxe4?! Rxe4] 14...Kb8 15.f3 Nf6 16.g3 Qh5 17.a4?

This is a slow approach in this sharp position. Better to develop with. [17.Bd2] 17...Ng4! 18.fxg4 Bxg4 19.Nf4 [19.Nc3 Bxd4+ is curtains.] 19...Bxd4+ 20.Kg2 gxf4 21.Bxf4 Be5 22.c6 Bc8?! [22...b6!] 23.Qb4 Bd6 24.Qb3 Bxf4 25.Rxf4 Re3 26.Qc2?! [26.Kg1] 26...Qh3+ 27.Kh1

27...Rxg3 28.cxb7 Bxb7 29.Rxf7 Rc8 30.Bb5 d4+ 31.Bc6


31...Rc3! 0-1
