Ivanov continues amazing tournament performance with a victory over FM Andy Lee as he looks to secure Summer TNM Championship.


Aleksandr Ivanov converted the king and pawn endgame to keep sole first in the Summer TNM

Aleksandr Ivanov continued his amazing run in the 2019 Summer TNM with a victory in round 5 against FM Andy Lee. With 3 rounds remaining, he is in sole first in the Championship section with 4.5/5, his sole draw coming against pre tournament favorite FM Kyron Griffith. Griffith continued his chase on the leader with a decisive win against NM Russell Wong. FM Ezra Chambers, who will be attending Webster University in the fall and studying with Susan Polgar and the championship chess team in St. Louis, also kept pace with a win against NM Rui Yang Yan. So the top of the leaderboard has Ivanov at 4.5, with Griffith and Chambers at 4 and many strong players looking to make a move at 3.5. Consistency will be the key here for Ivanov to hold on to the lead, and the champion will likely be the player that can maintain high quality play against difficult opponents over the next 3 weeks. 

Ella Papanek shows she is a cut above the field so far in the tough A/B section of the TNM

In the A/B section, Ella Papanek has returned to the Mechanics’ Institute Chess Club and has brought her top game with her, as she won against Teodoro Porlares and has sole first with 4.5/5, the lone half point coming as a result of a bye in the first round. Mansoor Mohammed is at 4/5 and a few players are a point behind at 3.5. The next week could be an opportunity for Papanek to create separation from the field, but it also provides an opportunity for Mohammed to leapfrog into the lead and allow others into the chase.

In the under 1600 section, there is a 3-way tie for first at 4.5/5 between Michael Baer, Romeo Barreyro, and Gregory Rousso. The next round should produce some exciting chess that will thin the race even more and establish a clear favorite. 

As we head into the championship rounds, we will be broadcasting the top board in the A/B section on board 9 of our DGT boards and the top u1600 board on board 10.

2019 Addison Memorial a Resounding Success as FM Kyron Griffith tops the field in our $5000 Guaranteed Event.

It was a full house at the Mechanics’ Institute Chess Club for the Addison Memorial this past weekend!

A $5000 guaranteed prize cool and long time control 3-day event attracted 90 players to the 2019 Addison Memorial, with many of the nation’s top scholastic players as part of the field. We also broadcast the top 6 boards in the open section and the top board in the A, B, C and DEu sections, creating some buzz and excitement for players and spectators alike. When it was all said and done, FM Kyron Griffith won the event outright and the $1000 prize with 4.5/5, made possible with a dramatic come from behind win in round 4 against FM Ezra Chambers. 


FM Kyron Griffith and FM Ezra Chambers attracted quite a large crowd to observe the ending of their round 4 game.

That game was the match of the tournament, as FM Chambers had a decisive advantage, but let it slip in time pressure. The final minutes produced some exciting dramatic chess as both players were looking to go for the kill under intense time pressure and a complicated position. You can watch the broadcast of the final minutes with commentary by GM Nick de Firmian, FM Paul Whitehead and guest IM Vincent McCambridge by clicking this link to the 3:37:00 mark:

It was a joy to see so many strong scholastic players across all sections, may of which ended up finishing in the money. We hope to see many of them back again in our events!


Many of the nation's top scholastic players participated, including Milind Maiti, Chelsea Zhou, Maurya Palusa, Rui Yang Yan, Ashley Pang, and Shaashwath Sivakumar.

In the A section, MI regular Daniel McKellar shared first with Sathvik Singireddy with 4/5. In the B section, Teodoro Porlares and Tony Zhou shared first with 4/5. In the C section, Mateo Hansen used a great queen sacrifice in the final round to win his game and take sole first with 4.5/5. In the DEu section, Robert Wang and Prescott Yu shared first prize with 4/5. 

What made the event even more fun was our live broadcast, where many parents in the meeting room could follow their children’s games and where many followed from home and from around the world.

My Mechanics' Institute Story by Andy Kim


My brother taught me how to play chess when I was five. Throughout my childhood, I improved to the point where I even beat him once. Later on in middle school, I defeated all of my classmates, and felt like I was actually pretty good at this game. However, due to other interests, I unfortunately didn’t have the motivation to pursue chess more seriously. 

When I stumbled upon online chess ( in college, I also discovered, along with it, the Elo rating system and the incredible number of levels of mastery in chess. I found out that the 12-year-old-me was wrong; I was actually a tiny, weak fish in a vast ocean of chess players! The game all of a sudden did not look so simple, and my curiosity for chess was re-ignited; I was hooked on online chess. 

After I graduated from college last year and moved to SF for work, I found that I now had some time in the evenings after a 9-5 job, so I started going to the local chess club, the Mechanics’ Institute. There I played my first over-the-board tournament, and had a great showing. I was having so much fun throughout my first tournament that I ended up becoming a MI member and regular competitor in the TNMs and weekend tournaments. 

Looking back at the experience overall as I now prepare to move back to the East Coast, the Mechanics’ Institute provided a place for me to discover a new layer of the game I’ve loved. MI delivers a higher-level experience of being a chess club, thanks to all these new advancements from the Twitch livestream, DGT boards, the active social media accounts, to the numerous partnerships that the club has had with other chess organizations. MI’s efforts to contribute to the chess community at large has even inspired me to post on Instagram about chess (ig: @andykimj), write in my own blog (, and occasionally stream chess on Twitch myself. 

​I now leave as a B-player with aspirations of becoming an NM someday (I was probably about a C-player last year)… although there won’t be a place like MI on the East Coast, I know I’ll be doing whatever I can to promote chess in my community, just like how the community at MI has been doing. MI not only gave me an enjoyable one-year experience, but also gave me the foundation to grow a lifelong hobby - and for that I am thankful. I hope to visit soon and compete in this historic club again. 


Mechanics’ Club Player Gets the Attention of Jon Speelman


The Mechanics’ Institute has its share of characters from various backgrounds, but this one took me a bit by surprise. Club regular Guy Argo, who is also a racecar driver, shared some of his games with Jon Speelman in an article for Chessbase.

Friendly Rivalries, Part 12

By FM Paul Whitehead

IM Elliott Winslow is a good friend of mine, and we have shared long-time friendships with many folks in common, of people inside and outside of this Game of Chess.

Elliott Winslow 1975

Elliott’s accomplishments in the Chess World are many, including state champion of Missouri multiple times, and many times winner of the North American Open.  He became an International Master in 1986 here in San Francisco, at the 2nd Miz Brown’s Tournament.
Elliott counts playing world #2 Korchnoi at the Pasadena US Open in 1983 as just one highlight in a career that has spanned both coasts and everything in-between. 
Elliott worked for the U.S. Chess Federation as assistant editor for Chess Life, and has played Backgammon and Poker professionally.  After being semi-retired for 16 years he was lured back into chess and the Bay Area in 2011 by IM John Donaldson, to work as part of the Mechanics’ Institute Chess Team.
Since his return, Elliott has proved to be a very strong, resilient and active player.  He has won the MI Chess Club’s flagship event the Tuesday Night Marathon countless times, and last month won the Northern California Senior Championship here at the MI, earning him a trip to Florida for the US Senior Championship later in the year.
Elliott has earned the sobriquet “Alley-Cat” for his many lives.
Elliott and I played 7 times over a span of 11 years, from 1976 to 1987, with 2 wins apiece and 3 draws.  It seems we were rather evenly matched- perhaps we had a certain respect for each other.  
Another question is why Elliott and I both have difficulty in recalling these games.
And so this becomes an exercise in memory: 
Who were these chess-players?

(1) Winslow,Elliott C (2364) - Whitehead,Paul A (2197) [A56]
Golden Gate op San Francisco (1.6), 03.07.1976

A hard-fought draw in our first encounter. White tries to break Black's grip by sacrificing the exchange with 23.Nxf4, and the game swung in the balance before petering out into a drawn Rook ending. Notes by Winslow. 1.d4 Nf6 2.c4 c5 3.d5 e5 4.Nc3 d6 5.e4 g6 6.Nf3 Bg7 7.Bg5 [Maybe I should wait until 7.Be2 0-0 8.Bg5] 7...h6 8.Bh4 [8.Bd2!?] 8...g5 9.Bg3 Nh5 10.Qc2 Nf4 


11.h4 a6 12.Rh2?! [12.hxg5 hxg5 13.Rxh8+ Bxh8 14.Nd1 -e3-f5] 12...Nd7 13.0-0-0 g4 14.Nd2 Nf6 15.f3 What else? 15...N6h5 16.Bxf4 [16.Be1 g3 17.Rh1 Bf6 18.Ne2 ...-/+] 16...exf4 17.fxg4 Bxg4 18.Be2 Bxe2 [18...Qd7] 19.Nxe2 b5 Not necessarily good 20.Rh3?! [20.Rhh1!?] 20...Be5 

21.Qb3 Interesting but not necessarily good. 21...Rb8 22.Qf3 Ng3 23.Nxf4 Bxf4 24.Rxg3 Bxg3 25.Qxg3 Qf6 26.e5 Qg6 27.Qe3? Cheap -- [better 27.Qf4!] 27...0-0 28.exd6 Qxd6 29.cxb5 Rxb5 30.Nc4 Qf6 

31.d6 Qxh4 32.g4 Somehow I thought this prevented his next! 32...Qg5 33.Qxg5+ hxg5 34.Rd5 f6 35.Kc2 Kf7 36.a4 Rbb8 37.b3 [37.Rxc5 Rbc8 38.Rxc8 Rxc8 39.Kd3 Ke6 intending ...Rh8] 37...Rfc8 38.Kd3 Ke6 39.Ke4 Rg8 40.Rd3 Rgd8 

41.Ke3 Rd7 42.Ke4 Rbd8 43.Rd5 Rb8 44.Rd3 Rbd8 45.Rd5 Rxd6 46.Nxd6 Rxd6 47.Rxc5 Rb6 48.Rc3 Rb4+ 49.Kf3 Ke5 50.Rd3 Ke6 



(2) Winslow,Elliott C (2317) - Whitehead,Paul A (2322) [B49]
LERA May Sunnyvale (4.2), 28.05.1978

Black doesn't play with enough heart, chooses a difficult opening variation, gives up the ghost with barely a squeek. Not my best game by a long shot. 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 a6 6.Be2 Qc7 7.0-0 Nf6 8.Be3 Bb4 9.Na4 0-0 10.Nxc6 bxc6 

11.c4 Be7 If 11...Nxe4 12.Qd4 or 12.c5 leave White with a strong grip on the position. Perhaps 11...Bd6 is best here. 12.Bf3 d6 13.Bf4 e5 14.Bg5 Be6 15.Rc1 Rfd8 16.Qe2 Rab8 17.b3 h6 18.Be3 c5 Maybe it was better to stay flexible. In that case 18...Nh7 might suggest itself. 19.g3 Bf8 20.Nc3 Re8

21.Bg2 Nd7 Black has no plan and goes under quickly with this bad move and the next. 21...a5 is the right idea. 22.f4 f6? 22...exf4 followed by 23...Nf6 is the last chance to hold. 23.f5 Bf7 24.Bf3 Black is without counter-play. 24...Rbd8 25.Kf2 Nb8 26.Bh5 Nc6 27.Nd5 Qb7 28.g4 Kh8 29.Rg1 a5 Too late. 30.h4 Bxh5 31.gxh5 Nb4

Black might have lost on time, as there's still a bit of play left. My memory does not serve me. However, after his previous dis-spirited play, resigning is totally justified. 1-0


(3) Whitehead,Paul A (2391) - Winslow,Elliott C (2406) [B92]
9th Bagby San Francisco, 01.1984

A see-saw battle where Black suddenly gets knocked out, probably due to time-pressure. 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be2 e5 7.Nb3 Be7 8.0-0 0-0 9.Be3 Be6 10.a4 Qc7

11.f4 exf4 12.Rxf4 Nbd7 13.Qd2 Ne5 14.Nd4 Rfe8 15.Raf1 Rad8 16.Nf5 Nfd7 17.R4f2 Bf8 18.Bd4 Qa5 19.Rd1 Rc8 A complicated position. Now White might try 20.Qg5 to stir things up. 20.b3 Not good here. White's attempt at "strategic" play leaves him worse. 20...g6

21.Ng3 Rc7 22.Bf3 Rec8 23.Nd5 Qxd2 24.Rdxd2 Bxd5 25.exd5 Now 25...Bh6! 26. Rde2 f5! is quite strong. 25...b5 Now the game hangs in a delicate balance. 26.axb5 axb5 27.Be2 Bh6 28.Rd1 b4 29.Ne4 Bf8 30.Ba6 Ra8

31.Bb5 Ra2 32.c4 Rxf2 33.Kxf2 h6 34.Ke2 f5 35.Nd2 Bg7 36.Ra1 Nxc4 37.Ra8+ Kh7 38.Bxg7 Simply 38...Ncb6 39.Ra6 Kxg7 is equal. 38...Nxd2?? 39.Bd4

Black loses a piece or is mated. 1-0


(4) Winslow,Elliott C (2365) - Whitehead,Paul A (2370) [E69]
10th Bagby San Francisco (2), 1985

Not a bad game on my part, but not a particularly good game on Elliott's side either. 1.d4 Nf6 2.c4 d6 3.Nc3 Nbd7 4.e4 e5 5.Nf3 g6 6.g3 Bg7 7.Bg2 0-0 8.0-0 c6 9.b3 Re8 10.h3 a6

11.Be3 exd4 12.Nxd4 Nc5 13.Qc2 Qe7 14.Rfe1 Bd7 15.f3 b5 16.b4 Looks good, but maybe 16.Rad1 instead. 16...Ne6 17.c5 dxc5 18.Nxe6 Qxe6 19.Bxc5 Nh5 Suddenly White finds himself in a bit of trouble. 20.g4 Dubious- there go the dark squares. 20.Kh2? Nxg3! is also bad. Why not simply 20.Bf2? 20...Nf4

21.Rac1 a5 22.a3 axb4 23.axb4 Ra3 White is in serious trouble. 24.Qd2 Be5 25.Ne2 Nd3 26.f4 Nxc1 27.Rxc1 Ra2 28.Qe3 Rxe2 29.Qxe2 Bxf4 30.Rd1 Ra8

31.e5 To free his game, but it works only somewhat. 31...Bxe5 32.Kh1 Ra1 Black is technically-minded, as usual. 33.Rxa1 Bxa1 34.Qd2 Be5 35.Bf3 Kg7 36.Kg2 f6 37.Be4 h5 38.Bf3 h4 39.Qd3 Qa2+ An inevitable incursion. 40.Bf2 Be8

The time-control is reached, White is 2 pawns down and there's little point in playing it out. 0-1


(5) Whitehead,Paul A (2370) - Winslow,Elliott C (2365) [B99]
San Francisco Intl 1st San Francisco (8), 19.10.1985

A game rather typical of me. A dubious pawn sacrifice 12.e5 followed by a lot of nothing, but just enough for murky play. Both players are peacefully inclined. Notes by Winslow. 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Be7 8.Qf3 Qc7 9.0-0-0 Nbd7 10.Bd3 [I wondered if he was going to play Wolff's line 10.g4 b5 11.Bxf6 Nxf6 12.g5 Nd7 13.f5 Nc5 14.f6 gxf6 15.gxf6 Bf8 16.Rg1; or the 10.Be2 silliness] 10...h6 

[10...Nc5!?] 11.Qh3 Nb6 12.e5!? dxe5 13.fxe5 Qxe5 14.Nf3 Qc7 15.Rhe1 Nbd5 [15...Nbd7!?] 16.Nxd5 Nxd5 17.Bxe7 Qxe7 18.Kb1 [18.Ne5!?] 18...0-0 19.Ne5 b5 20.Re4 f5!? [Maybe better is 20...Nf6 21.Rh4 Bb7 as 22.Rxh6 fails to 22...gxh6 23.Qxh6 Ne4] 21.Ree1 Bb7

[He thought he was worse and accepted quickly; I thought after 21...Bb7 22.Ng6 Qb4 (22...Qf6! Nick thought enough for the exchange23.a3 Nc3+ 24.Ka1 (24.Kc1=) 24...Qc5 25.Nxf8 (25.Rxe6 Nxd1 26.Ne7+ Kf7 (26...Kh7 27.Qh5) 27.Bxf5! Rfe8) 25...Nxd1 is okay] 1/2-1/2


(6) Winslow,Elliott C - Whitehead,Paul A [B09]
11th Bagby San Francisco (4), 18.01.1986

Another peaceful draw. Elliott and I never seemed to meet on a great day for either of us. 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.f4 Bg7 5.Bd3 0-0 6.Nf3 Na6 7.0-0 c5 8.d5 Rb8 9.Qe1 Nb4 10.a3 Nxd3

11.cxd3 e6 12.dxe6 fxe6 13.e5 Nh5 14.Ne4 dxe5 15.Nxe5 15.dxe5 is perhaps better, but White has little. Black is active. 15...Qd5 16.Be3 b6 17.Nc3 Qd6 18.Ne4 Qd5 19.Nc3 Qd6 20.Ne4 Black can now 20...Qb3 to keep the game alive, but instead... 20...Qd5



(7) Winslow,Elliott C - Whitehead,Paul A [A65]
12th Bagby San Francisco (7), 25.01.1987

Our final encounter, and Elliott absolutely clobbers me in a perfectly played game. 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 0-0 6.Bg5 c5 7.d5 e6 8.Qd2 exd5 9.cxd5 b6 10.h4

Now Black should seriously consider 10. ..h5. 10...Ba6 11.h5 Bxf1 12.Kxf1 h6? Panicking, but Black is already in trouble. 13.Bxh6 Nxh5 14.Nge2 f5 15.exf5 Rxf5 16.Bxg7 Kxg7 17.g4!

White's position plays itself, and with Winslow at the controls Black's doom is certain. 17...Rxf3+ 18.Kg2 Nd7 19.gxh5 Qf6 20.Ne4 Qf5 21.N2g3 Qg4 22.hxg6 Rf4 23.Qxf4!

After 23...Qxf4 24.Nh5+ Black is a Rook and Knight down. 1-0



Scholastic Corner

By Judit Sztaray

Girls in chess is a hot topic nowadays, it seems to be trendy topic to discuss and form your projects around. But what about 16 years ago? The situation was quite different then: with less than 1%(!) of USCF memberships belonging to females, dedicating a tournament just for girls seemed a controversial and not at all a sound initiative. Thank God for the visionary leaders like GM Susan Polgar, who together with Frank Niro and the rest of the Susan Polgar Foundation, created the very first all girls tournament. The Susan Polgar Foundation Girls’ Invitational was officially approved by US Chess back in 2003, and became the first all girls tournament to award a national title.
Fast forward 16 years, I was honored to be invited to be the chairwoman and the Chief Tournament Director for the Susan Polgar Foundation Girls Invitational event. Leading up to the event, we worked tirelessly for months to track down affiliates and ask for nominees from each state, and the countries in the Americas to secure strong players for this tournament. At the end, we had representatives from 38 states and DC and girls from 11 different countries at this year’s tournament that took place June 22-27 at SPICE, Webster University, Saint Louis, MO. It was not only the largest attendance ever, but also the strongest field in the history of SPGFI. The top 20 players were all 2000+ rated with 3 girls over 2200+. Northern California was represented by no less than five girls: Rochelle Wu lead the delegation, followed by Omya Vidyarthi, Anika Rajaram, Mai-ha Nghiem and Marina Xiao. 

The amazing and cool thing about this event is while it’s a tournament, it also feels like a camp, since all the girls are staying in one building, eat meals together, and have side events together. I enjoyed seeing all the girls socialize, have the opportunity to make new friends and have fun during these 6 days.
Side events included blitz, bughouse, the famous Polgar puzzle solving competition, and also an interesting alumni panel discussion, where former SPFGI players, such as the popular streamer Alexandra Botez, came back and discussed how chess and this tournament impacted their lives. Game analysis sessions with titled players, such as GM Illya Nyzhnyk, who recently won the National Open in Las Vegas; live streaming of after round decompression with Alexandra Botez; and dance class with a Cuban instruction were just the few extras that made this event truly one of the kind.

The main event itself is a 6 round, G/90 +30s inc tournament where the girls compete in one open section. Stakes are high with cash prizes and scholarships on the line, so girls had to take every round very seriously. Before the last round there were no perfect scores and still nine girls were within reach of the first place, that comes with $4000 and a full 4 year scholarship to Webster University. Interesting fact that on the second board, the 9 year old Alice Lee from Minnesota was the second youngest competitor in the whole field, the fact that she had a shot at the title was alone sensational.

At the end, the match between WIM Emily Nguyen from Texas and WIM Mitzy Caballero from Peru was the deciding one, and with a thrilling upset, Mitzy won and took the clear first place and became the 16th SPF Girls Invitational Champion.

Frank Niro wrote a summary article that was published on and included their game. I’m including it here for your enjoyment.

As I’m flying back from MO, it gives me enormous gratification to know that this event truly made a huge difference in 82 girls’ lives. I hope to see more and more of these events, since none of these should be viewed as competing events, rather than more opportunity for girls to play with other girls, strengthen their dedication to chess and serve as a calling to other girls to come and compete in rated events.
Finally, I’d like to thank the Mechanics’ Institute Chess Club and its committee for supporting me in this role.


Nick de Firmian's Column: Learn from the World Champions

This week: Boris Spassky

Boris Vasilievich Spassky was born on Januarry 30, 1937. In the summer of 1941 he was dying of starvation in an orphanage in the besieged city of Leningrad. Yet his father (a soldier) recovered in the death ward and rescued Boris, after which the family managed to slip out of Leningrad to the outskirts of Moscow where they stayed until after the war. Boris notes they were incredibly lucky to slip out of Leningrad in the second group as the first and third were bombed.

Spassky quickly developed into a major chess talent in the post war Soviet Union. He became a grandmaster at the age of 18 – one of the very youngest at the time. He reached the world elite by 1960 and won his first USSR Championship in 1961. He won the Candidates matches in both 1965 and 1968, defeating the likes of Keres, Tal, Korchnoi and Gellar. He ascended the throne with his match victory over Petrosian in 1969.

Yet Spassky will forever be remembered for the Match of the Century in 1972. He lost his crown to Fischer in Reykjavik Iceland, but the match garnered such tremendous publicity that chess has never seen before or since. It was front page news and covered on every major television station. The great contribution of Spassky was to show to world what a humanist he was despite the extreme intensity of the chess match and the cold war relations between Russians and Americans. Spassky is greatly respected by his grandmaster colleagues for his noble character. Spassky came to the Mechanics’ Institute in 2008 and played a simul. This is well remembered today, but also because he suffered a minor stroke at the club. Fortunately MD Tony Saidy was present.  Spassky is the oldest living former World Champion as 82 years.

(1) Spassky,Boris - Bronstein,David
USSR Championship, 1960

1.e4 e5 2.f4 exf4 3.Nf3 d5 4.exd5 Bd6 5.Nc3 Ne7 6.d4 0-0 

Spassky has ventured the King's Gambit against Brontstein, one of its practicioners. The position is about even here. 7.Bd3 Nd7 8.0-0 h6?!

More straightforward is 8...Nf6. 9.Ne4 Nxd5 10.c4! Ne3 11.Bxe3 fxe3 12.c5 Be7 13.Bc2

White has gained squares in the center. All he needs to do is capture the e3 pawn to have a good advantage. 13...Re8 14.Qd3 e2


A bold sacrifice! Bronstein should try 15...exf1(Q)+ 16. Rxf1 Bxd6 17. Qh7+ Kf8 18. cxd6 but he seeks a safer continuation. 15...Nf8?

16.Nxf7!! Sacrificing the knight AND allowing the rook to be taken with check! 16...exf1Q+ 17.Rxf1 

17...Bf5 Trying to stem the tide. On 17...Kxf7 18. Ne5+ Kg8 19. Qh7+! Nxh7 20. Bb3+ Kh8 21. Ng6 is mate. 18.Qxf5 Qd7 19.Qf4 Bf6 20.N3e5

The attack is too powerful now. 20...Qe7 21.Bb3 Bxe5 22.Nxe5+ Kh7 23.Qe4+

Bronstein resigned as both 23...g6 and 23...Kf8 are met by 24. Rxf8! with mate coming shortly. This brilliant game was part of the plot in the 1963 James Bond film "From Russia with Love." The brilliant villain Kronsteen plays the White side in the movie. 1-0


(2) Larsen,Bent - Spassky,Boris
USSR vs the World, 1970


Larsen plays the opening named after him with which he had great success. 1...e5 2.Bb2 Nc6 3.c4 Nf6

Spassky plays for direct development and control of the center - classical principles. 4.Nf3 e4 5.Nd4 Bc5 6.Nxc6 dxc6 7.e3 Bf5

Black develops with all haste. Already Black's position is easier to play.  8.Qc2 Qe7 9.Be2 0-0-0

10.f4?! Black is completely developed and now initiates actions. Larsen should have devoped with 10. Nc3 10...Ng4! 11.g3 h5 12.h3




Spassky sacrifices a knight to open the kingside. No doubt Larsen was somewhat worried, but it appears he can take the knight and weather the storm. 13.hxg4 hxg3 14.Rg1

14...Rh1!! This incredible shot makes the attack work. Spassky gives up a whole rook to gain a tempo for the pawn. 15.Rxh1 g2


16.Rf1 No better is 16. Rg1 Qh4+ 17. Kd1 Qh1 16...Qh4+ 17.Kd1 gxf1Q+

Larsen resigned as 18. Bxf1 Bxg4+ is the end. 0-1


(3) Andruet,Gilles - Spassky,Boris
Bundesliga, 1988

1.d4 Nf6 2.c4 e6 3.Nf3 Bb4+ 4.Bd2 Bxd2+ 5.Qxd2 d5 6.Nc3 0-0 7.e3


The opening is reasonable for both sides and very typical. 7...Qe7 8.Rc1 Rd8 9.Qc2 Nbd7 10.cxd5 exd5 11.Bd3 Nf8 12.Ne2 c6


The game has reached a position that can arise from the Queen's Gambit Declined, Exchange Variation. 13.0-0 Ng6 14.Ng3 Re8 15.Qc5 Qd8 16.Nd2 Nh4 17.b4


White plays the minority attack to break up the pawns on the queenside. Spassky has avoided the exchange of queens to keep attacking possibilities on the kingside. 17...a6 18.a4 Bd7 19.Rb1 Ng4 20.Qc2 g6 21.b5 axb5 22.axb5 h5


23.bxc6 bxc6 24.Rfe1 Qf6 25.Ndf1?


This is a bad square for the knight. Black's pieces become more active. 25...Ra3 26.Re2


26...c5! This suprising break has hidden poison. White needs to play 27. Bb5 now to stay in the game. 27.dxc5? Ne5! 28.Bb5




This amazing shot is immediately decisive. Now 29. gxf3 Nexf3+ 30. Kh1 Bh3 and 31...Bg2 mate is coming. Andruet resigned. 0-1


(4) Spassky,Boris - Petrosian,Tigran [B94]
World Championship, 1969

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6

Brave of Petrosian to play a Sicilian Najdorf!  6.Bg5 Nbd7 7.Bc4 Qa5 8.Qd2 h6


Black lags in development but has the central pawns to keep the white pieces out. The question is how long they can do that. 9.Bxf6 Nxf6 10.0-0-0 e6 11.Rhe1 Be7 12.f4 0-0 13.Bb3


White is completely developed and has some initiative. Petrosian is famous for defense however. 13...Re8 14.Kb1 Bf8


15.g4! Spassky begins the attack with this pawn sacrifice! The threat of 16. g5 forces Petrosian to accept it. 15...Nxg4 16.Qg2 Nf6 17.Rg1 Bd7 18.f5 Kh8 19.Rdf1 Qd8?! [19...Qe5 is the best chance to defend.] 20.fxe6 fxe6 


21.e5! dxe5 22.Ne4! All of White's pieces jump into the attack. Even Petrosian can't defend this. 22...Nh5 23.Qg6 exd4 



24.Ng5 [24.Ng5 is the final blow; After 24...hxg5 25.Qxh5+ Kg8 26.Qf7+ Kh7 27.Rf3 mate is imminent.] 1-0
