 Fall TNM Begins! 

The Mechanics' Institute signature event began its final tournament of the year, as the 2019 Fall Tuesday Night Marathon brought many new faces to experience the 9-round gauntlet that tests stamina, consistency and good old fashioned intestinal fortitude. Anything can happen, and we bring the drama of the top games in each section live to all viewers via our Twitch channel. 

In the Championship section, FM Kyron Griffith, NM Eric Li, and IM Elliott Winslow won their first round games as the top 3 seeds so far. The biggest upset of the round came from Gianluca Pane (1887) who defeated WFM Natalya Tsodikova (2196). 

The Fall 2019 TNM welcomed back our regulars and brought new faces

The A/B section currently has 33 players and looks like it will be a very competitive section, as will the currently 44 player under 1600 section. The 9-round format should be enough to determine supremacy in this end of the year TNM.

As a teaser for next year, we will be incorporating at least one Open section TNM. We think this will add good balance for those that like to see this format while at the same time preserving the benefits and competitive games from a multi-section TNM. It is great to see and feel the action and live commentary on Tuesday nights. This week, we had Laura Goodkind talking about her upcoming new book Queen for a Day: A Girl's Guide to Chess Mastery. Lauren has done a great deal in support of bringing more girls and womwn into chess and it was a pleasure to hear her talk about her life, her students and her passion for the game. Please visit Lauren's site here:

Next week we are scheduled to have former Mechanics' Institute Chess Director FM Jim Eade join us on the broadcast to talk about his new project and help Paul Whitehead provide live commentary on the games. It will be another exciting evening!

GM Patrick Wolff Gives Talk on New Book

Prior to the start of the TNM, GM Patrick Wolff gave a talk regarding the release of his updated re-branded edition of what was the Complete Idiot's Guide to Chess, newly called Learn to Play Chess Like a Boss. While it makes current the classic edition for people new to the game, it also has a brand new section dealing with AI and how it affects the understanding of chess. Most of the audience questions centered around this topic and made for a lively discussion, especially living in the Bay Area.

We do also have a few copies in the chess office at a discounted price, please inquire if you are interested.

IM John Donaldson Wins Prestigious Botvinnik Award From FIDE

Former Mechanics' Institute Chess Director John Donaldson was awarded the Botvinnik Award by FIDE, which is awarded for the best trainers for his long time work as Captian of the U.S. Olympiad teams. In an email exchange with Jude Acers, John proclaimed "Canis omni die sua" (Every dog has his day). While this may be true, John certainly has done enough over the course of his career to deserve many such days, and we are all happy he was recognized for his work on the International scene on behalf of the United States. We were also pleasantly pleased to see him come and compete in the October edition of our Monday Night Rapid series at the club. Congratulations to the legend, for yet another milestone.

Friendly Rivalries, Part 15.

The Seattle Futurity and the early 1980’s.

By FM Paul Whitehead

I left off this column about battles with my contemporaries earlier, here:

The 1970’s were finally over, and as I hit 20 years of age my interest in chess had waned to almost zero.  In the year 1980 I played in exactly one tournament, the Paul Masson American Class Championship in Saratoga.  This time I could not repeat my success of the previous year when I tied with GM Nick de Firmian for 1st place.  After delivering checkmate on the board(!) in rounds 1 and 2 against masters Dorsch and Krystall, I was ground down by GM Larry Christiansen in the 3rd round.  A short draw against master Gabriel Sanchez in round 4 finished the year for me – only 4 games of chess!

I had started to look around at other things that interested me in the wider world, and had begun training and working as a nursery school teacher.  Chess was far away…

In 1981 I played in 4 or 5 events, but the increase in activity wasn’t backed up by serious study, and my results were only so-so.  I was occasionally able to pull off a swindle, but my heart wasn’t in it, and it showed in my games and results.  Not one game from the US Open in Palo Alto where I scored 8.5 - 3.5 is worth inclusion here, for example.

But in 1982 I really took my indifference in chess to new heights (or lows, rather).  The year started out somewhat well, and my chess seemed inspired, even if I wasn’t. Playing in the Charles Bagby Northern California Championships at the Mechanics’ Institute in January, I scored a middle of the road 3.5 - 2.5. I won three nice games, vs. Richard Lobo, George Kane and Vince McCambridge - all given in previous columns.  However, I lost to both John Grefe (also given previously) and Charles Powell – the only time Charlie beat me.  A draw with Jeremy Silman rounded out the event for me.

Six months later I found myself visiting and staying with a chess master friend of mine in Seattle over the Summer. While enjoying the warm weather, and visiting my good friend Steve Brandwein down at the famous Last Exit Coffeehouse, I was somehow recruited to play in a newly minted “futurity” tournament.  Back in those days FIDE ratings were rare, but I had one, and so my presence was a chance for local talent to get rated by the World Chess Federation.  I was probably offered a small yet princely sum to participate, as I now cannot imagine another reason why I agreed to play…

The tournament was interesting, however, even if my interest in chess had flagged.  Legendary master Victor Pupols was on board, as well as strong up and comers Eric Tangborn and John Donaldson (future Director of the MI Chess Club).  Other participants included Alexey Rudolph (now Dr. Alexey Root, chess and education maven) and Robert Ferguson, current Attorney General of Washington State.

Dr. Alexey Root

Unfortunately, and unbeknownst to myself, I had walked into what can only be described as the Seattle version of the feud between the Hatfield’s and the McCoy’s!  It turned out that the friend I was staying with (who shall remain nameless), himself a strong master and FIDE rated, had not been invited, or had refused his invitation to the tournament.  I cannot recall, and no matter: he was no friend of some of the players. And two of them in particular, whose identities will be revealed in the games to follow.

 Perhaps another recounting of this tournament and its origins will throw some light here, but, needless to say, I found myself in a predicament: I was in a need to win situation precisely when I felt no need to win!  Chess bored me!  But, if I lost to these two fellas, I was likely out on my ear, and worse yet, out on my ear on those drizzly Pacific Northwest streets!  The couch where I so lazily snoozed would be ripped away: I would find no mercy from my friend.  These were his sworn enemies, and only total victory would satisfy his lust for their blood…

So now, instead of enjoying the occasional glimpse of Yasser Seirawan down at the Exit while strolling around with a coffee in one hand and a cigarette in the other, or having deep conversations with beautiful baristas on their breaks like any normal 22-year-old, I found myself deep in the middle of an ancient conflict…

Dear reader, to see how I prevailed (and I did prevail!) look below at these struggles.  Try not to cry- or laugh too loudly.  It’s only chess, but deadly serious too!

(1) Dorsch,Thomas - Whitehead,Paul [E98]
Paul Masson , 1980

Tom Dorsch was a frequent participant in Bay Area tournaments back in the day. He went on to become involved in the politics of chess locally and nationally. I counted Tom as one of my friends in the chess community - we always shared a laugh together over this and that. But in this game the Tom I knew was absent: he gets totally rolled. 1.c4 g6 2.Nc3 Bg7 3.d4 Nf6 4.e4 d6 5.Be2 0-0 6.Nf3 e5 7.0-0 Nc6 8.d5 Ne7

A position seen hundreds of thousands of times. It is hard to believe White will be mated in only 8 moves!9.Ne1 Nd7 10.Nd3 f5 11.f4 exf4 12.Nxf4 Nc5 13.exf5 Nxf5 14.Nd3 Qh4 15.Ne1 Bd4+ 16.Kh1 Ng3#


(2) Whitehead,Paul - Krystall,Danny [C18]
Paul Masson, 1980

Danny Krystall is a master from Southern California. I don't know much about him except that he played in Lone Pine 1974, played a somewhat poor game against me here in 1980, and is still active now in 2019. 1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Ba5 6.b4 cxb4 7.Nb5 b3+ 8.c3 Nh6 9.Bxh6 gxh6 10.Qxb3

Black's free-wheeling approach to the opening has already put him in a difficult position. 10...Nc6 11.f4 f6 12.Nf3 0-0 13.Bd3 Qb6 14.Qc2 a6 15.Bxh7+ Kh8 16.Qg6!
The Queen chases her ally the Bishop right into the Black king's lair, with deadly effect. Black is busted.16...axb5 17.Qxh6 Bxc3+ 18.Kd1 Qc7 19.Nh4! Nxe5 20.dxe5 Qxh7 21.Ng6+ Kg8 22.Qxf8#


(3) Whitehead,Paul - Osbun,Erik [C91]
Cal. Masters, Berkeley, 1981

Erik Osbun played chess for over 40 years as a strong master, and as recently as 2018 has written for the MI Chess Club Newsletter. Erik played Bobby Fischer in a clock-simul in 1964 (he lost). Typical of young players, I just saw an older player that I hoped to bamboozle, and bamboozle him I did. 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 d6 8.c3 0-0 9.d4

I played this frequently, as a way to avoid a lot of theory. White allows the pin after...Bg4.9...Bg4 10.h3 Bxf3 11.gxf3 Na5 12.Bc2 Nh5 13.f4
A sacrifice, before Black grips the dark-squares with...Bg5.13...Nxf4 14.Bxf4 exf4 15.Qf3 Bg5 16.Nd2 c5 17.dxc5 dxc5 18.Rad1 Qe7 19.e5
White has the initiative, but the position is fairly level - Black is fine.19...Rad8 20.Qe4 g6 21.b4 Nb7 22.Nf3 Rxd1 23.Rxd1 Rc8 24.Kh2 Bh6
It was safer to redeploy the Knight with 24...Ne8, but White's next is maybe an overreaction...25.e6!? Ditching another pawn. 25...fxe6 26.Ne5 Rc7 27.bxc5
Now 27...Nxc5! 28.Qa8+ Bf8 29.Bxg6?! Qf6! works for Black. But everything is still in a precarious balance, until...27...Qxc5 28.Ng4 Kg7 29.Qxe6 Qe7 30.Qd5 Qc5 31.Qe6 Qe7 32.Qb6!?
White shows fighting spirit, avoiding the repetition - and Black goes wrong immediately.32...Nc5? Black needed to try to cover the dark-squares: 32...Bg5! and it's unclear what's going on. Now 2 sharp blows and it's all over. 33.Re1! Qf7 If 33...Qxf7 34.Qf6+ Kg8 35.Nh6#. 34.Qd6! A powerful re-centralizing. Black has no defense. If 34...Bg5 35.Qe5+. 34...f3 35.Qe5+ Kf8 36.Qh8+ Qg8
Black resigns. 37.Re8+ is another end to the story. 1-0


(4) Whitehead,Paul - Braley,John [B07]
Seattle Futurity, 1982

I know little of John Braley, and this is the only time we ever met. There is a wonderful and heartfelt tribute by his friend, John Donaldson: This game, and the circumstances surrounding it, are detailed in the article above. It is surely a game no one could be proud of: a win on time in a grisly position, a game where White was outplayed from beginning to end, a game that served as a proxy in a feud the participants themselves didn't fully understand. I bore Braley no ill-will: it was fate -and perhaps fear itself - that handed me this fishy victory. 1.e4 d6 2.d4 Nf6 3.Nc3 c6 4.Bg5 Qb6 5.Qd2

White pitches a pawn.5...Qxb2 6.Rb1 Qa3 7.f4 h6 8.Bh4 g5 9.fxg5 hxg5 10.Bxg5
White wins the pawn back.10...Ng4 11.Nf3 f6 12.Bh4 Bh6 13.Qd3 Na6 14.Rb3 Qc1+ 15.Qd1 Qe3+
White is busted.16.Qe2 Nb4 17.Qxe3 Nxc2+ White loses a pawn. 18.Kd2 Ncxe3 19.Be2 Nxg2+ White loses pawn number two. 20.Kc2 Bf4
21.Be1 Nxe1+ 22.Rxe1 Nxh2 White loses pawn number three. 23.Nd2 Ng4 24.d5 Kf7 25.Nc4 Rh2
Black is winning...26.Kb1 b5 27.dxc6 Be6 28.Nd5 Bxd5 29.exd5 bxc4 30.Bxc4
30...Ne5 A little better was 30...a5, but we are just quibbling here. 31.Ba6 Rhh8 32.Re2 Rh1+ 33.Kc2 Nxc6?! Questionable. 33...Rc1+ 34.Kb2 Nc4+ 35.Bxc4 Rxc4 wins handily. 34.dxc6 Rc1+ 35.Kb2 Rxc6
36.Bb7 Rac8 37.Bxc8 Rxc8 38.Rb7 Be5+ 39.Kb3 a5 40.Rb5-/+
Black lost on time! 1-0


(5) Ferguson,Robert - Whitehead,Paul [A30]
Seattle Futurity, 1982

This game has nothing to recommend it, just a historical note: Robert Ferguson is now the Attorney General for the State of Washington. 1.c4 Nf6 2.Nc3 c5 3.Nf3 e6 4.g3 Be7 5.Bg2 0-0 6.0-0 a6 7.b3

White goes his own way, as 7.d4 leads to Tarrasch - like positions.7...b6 8.Bb2 Bb7 9.d4 cxd4 10.Nxd4 Bxg2 11.Kxg2 Qc7 12.e4 Qb7 13.f3
And now we have a hedge-hog. Drawn at Black's suggestion - I probably had a movie to go see. 1/2-1/2


(6) Whitehead,Paul - Rudolph,Alexey [B06]
Seattle Futurity, 1982

Dr. Alexey Root is now an author, with her focus on chess and education. Back in 1982 she was Alexey Rudolph - a talented chess playing teen with pig-tails! 1.e4 g6 2.d4 d6 3.Nc3 a6 4.a4 Bg7 5.Be3 Nc6

Black plays the opening with sophistication and style.6.Qd2 e5 7.Nge2 f5 8.dxe5 dxe5 9.Qxd8+ Nxd8 10.g3
White is content to trade Queens, and is already thinking about an early cappucino at the Last Exit.10...Nf6 11.Bg2 0-0 12.0-0 Nf7 13.Rad1 Nd6 14.Bc5 Rd8 15.b3
Drawn at White's suggestion, I'm almost positive. Coffee time! 1/2-1/2


(7) Whitehead,Paul - Donaldson,John W [B31]
Seattle Futurity, 1982

1.e4 IM John Donaldson, author and historian, hardly needs an introduction. Many-time captain of the US Olympic team. Long time Director of the Mechanics' Institute Chess Club (1998-2018). However back in 1982 we were strangers. and I was under a mandate: win, or my goose was cooked! 1...c5 2.Nf3 Nc6 3.Bb5 g6 4.0-0 Bg7 5.Re1

White plays his favorite set-up. See MI Newsletter #867 in particular.5...Nf6 6.e5 Nd5 7.Nc3 Nc7 8.Bxc6 dxc6 9.Ne4 Ne6 10.b3
Black plays safe and sound. White tries something different.10...0-0 11.Bb2 b6 12.d3 Nd4 13.h3 a5 14.a4 f5
Maybe the wrong idea... see my game vs. Stearman also. 14...Qd5 looks better.15.exf6 exf6 16.Nxd4 cxd4 17.Qf3 Qd5 18.Nd2 Qxf3 19.Nxf3 c5 20.Nd2
White is slightly better.20...Ba6 20...Kf7! to challenge the e-file right away was correct. Black doesn't realize the danger. 21.Re6 Bh6? An outright blunder. Patient defense with 21...Rab8 was in order. 22.Ne4 Wins a pawn and soon the game. 22...f5 23.Nf6+ Kg7 24.Nd7 Rfe8 25.Rxb6

Discouraged, Black resigned. And White, who was faced with the dog house if he had lost, was instead given a hero's welcome! 1-0

GM Nick de Firmian's Column

Great Women Chess Players:  Week 1- Judit Polgar

Most of the world’s top chess players are men, and that has been even more the case in the past history of chess. There is no physical reason women shouldn’t play as well as men, yet cultural norms, economic opportunities and lack of role models have discouraged most women from the pursuit of a chess career. Chess is a battle of the minds, very combative and intense. In former times women were thoroughly discouraged from such endeavors, yet despite that we saw a few successfully rise to the challenge, particularly in the old Soviet Union. Nowadays there are a fair number of women chess professionals in the world.  These columns of the Mechanics’ newsletter during the Fall TNM will be dedicated to the great women players throughout the years.

This first week we start with probably the best ever woman player – Judit Polgar. Judit comes of course from the famous Polgar family, the three super talented girls taught by their father Lazlo Polgar. The oldest sister Susan (Zsuzsa) and middle sister Sofia have earned the (men’s) GM and IM titles – remarkable achievements themselves. Judit however is at a whole other level, competing with the top men in the world and landing on the world’s top ten of the rating list for a decade. She also has a particular style – super aggressive attacking play! Any soft sentiments about the fairer sex would be extremely misplaced if you sat down across the board from her.

(1) Judit Polgar (2677) - Viswanathan Anand (2781) [B81]
Dos Hermanas Dos Hermanas ESP (1), 06.04.1999

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e6 7.g4 Diagram

Judit plays a sharp variation against Anand's Najdorf Sicilian. Many players avoid this continuation as the positons become too wild. 7...e5 8.Nf5 g6 9.g5! gxf5 10.exf5 d5! 11.Qf3 d4 12.0-0-0 Diagram
12...Nbd7 13.Bd2 dxc3 14.Bxc3 Diagram
White is two pieces down, but the attacking kingside pawns and lead in development is compensation. The position may be roughly evaluated as even. The most important thing to have here is courage! 14...Bg7?! Perhaps 14...Rg8 would be a better line. 15.Rg1 0-0 16.gxf6 Qxf6 Diagram
Black has given back one piece to remain one ahead and has castled. The open g file and active white pieces mean good compensation. 17.Qe3 Kh8 18.f4 Qb6?! [The text allows the attack to build quickly. A better try is 18...Re8] 19.Qg3 Qh6? Diagram
[The last good chance was. 19...Rg8 Now White has a forceful way to gain full control of the position.] 20.Rd6! f6 The black queen must keep guard of the bishop on g7 to prevent mate. White's last two moves have targeted the queen and Anand must defend in a way that gives himself a completely tied up position. 21.Bd2! e4 22.Bc4 b5 23.Be6 Diagram
Black still has an extra piece, but most of his are stuck, while White's pieces are extremely active. 23...Ra7 24.Rc6 a5 25.Be3 Rb7 26.Bd5 Rb8 27.Rc7 b4 28.b3 Rb5 29.Bc6 Rxf5 Diagram
30.Rxc8! Rxc8 31.Bxd7 Rcc5 32.Bxf5 Rxf5 33.Rd1 Kg8 34.Qg2 Diagram
Material is back to even, but there is no hope at all for Black. First the e4 pawn goes, and soon after the black king. Anand resigned. 1-0


(2) Judit Polgar (2681) - Garry Kasparov (2838) [C67]
Russia - The Rest of the World Moscow RUS (5), 09.09.2002

Kasparov was the greatest player of his generation. He had a great score against many of his competitors, and truth be told that included Judit. However, she played some good games against Garry such as this. Another game played in Linares 1994 saw Garry make a blundering knight move. The camera showed he released the knight, but then quickly grabbed it again to place it on a different square. The arbiter failed to enforce the losing move and Kasparov won as Judit sat in disbelief. 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 Diagram

Kasparov chooses the "Berlin Wall" which has been very hard to crack since the 2000 World Championship match. Perhaps he thought that Judit and her active inclinations would be ill at ease in the ending. 4.0-0 Nxe4 5.d4 Nd6 6.Bxc6 dxc6 7.dxe5 Nf5 8.Qxd8+ Kxd8 Diagram
The classic Berline endgame, which has been played hundreds of times now. 9.Nc3 h6 10.Rd1+ Ke8 11.h3 Be7 12.Ne2 Nh4 13.Nxh4 Bxh4 14.Be3 Bf5?! This gives White a little more time - valuable even in the endgame. Safer was the simple development 14...Bd7. 15.Nd4 Bh7 16.g4! Be7 17.Kg2 h5 18.Nf5 Bf8 [18...hxg4 19.hxg4 Bxf5 20.gxf5 Rh5 21.Rh1! Rxf5 22.Rh8+ Bf8 23.Bc5 would lose a piece.] 19.Kf3 Bg6 20.Rd2 Diagram
White has some grip on the position and a king side pawn majority. Judit has gotten real winning chances from this opening, which is impressive in itself. 20...hxg4+ 21.hxg4 Rh3+ 22.Kg2 Rh7 23.Kg3 f6?! 24.Bf4! Bxf5 25.gxf5 fxe5 26.Re1! Diagram
White has doubled pawns on the kingside. Yet the active pieces give her a clear advantage. 26...Bd6 27.Bxe5 Kd7 28.c4! A powerful move. The threat of 29. c5 forces Kasparov to weaken his pawn structure. 28...c5 29.Bxd6 cxd6 30.Re6 Rah8 31.Rexd6+ Kc8 32.R2d5 Rh3+ 33.Kg2 Rh2+ 34.Kf3 R2h3+ 35.Ke4 Diagram
35...b6 Judit is up just one doubled pawn, but her pieces are on strong squares. She worries not about a few checks on her king. 36.Rc6+ Kb8 37.Rd7 Rh2 38.Ke3 Rf8 39.Rcc7! Rxf5 40.Rb7+ Kc8 41.Rdc7+ Kd8 42.Rxg7 Kc8 Diagram
Kasparov played this, but then resigned. The two rooks on the seventh rank completely control the game. 1-0


(3) Polgar,Judit (2685) - Mamedyarov,Shakhriyar (2580) [C80]
Bled ol (Men) Bled, 2002

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Nxe4 6.d4 b5 7.Bb3 d5 8.dxe5 Be6 9.Nbd2 Nc5 10.c3 d4 11.Ng5! Diagram

This fantastic move was invented by Tal, and first played in the 1981 World Championship match by Karpov against Korchnoi. The point is that 11...Qxg5 12 Qf3 causes a lot of trouble. 11...Bd5 12.Nxf7! Kxf7 13.Qf3+ Diagram
13...Ke6 14.Qg4+ Kf7? This wild position is extremely difficult to play, and Mamedyarov goes astray. It was necessary to play 14...Ke7 with an obscure position. Now Judit is in her element. 15.Qf5+ Ke7 16.e6! Diagram
16...Bxe6 17.Re1 This looks like a position from the games of old - Morphy or Greco. Black is a piece ahead but his king is caught in the center. Judit keeps up the pressure. 17...Qd6 18.Bxe6 Nxe6 19.Ne4! Diagram
The white knight and bishop quickly jump into the game. That and the pin on the e-file create a decisive advantage. 19...Qe5 20.Bg5+ Kd7 21.Nc5+! Bxc5 22.Qf7+ Kd6 23.Be7+! Kd5 24.Qf3+ Diagram

Mamedyarov resigned. 24...Kc4 25. b3 is mate! 1-0
