Chess is Forever

Musings on the 2019 U.S. Amateur Team West Championship

BAC-1 (left) and BCS Wu Hoo! (right) finished tied for first at the 2019 U.S. Amateur Team Championship. They played to a 2-2 match draw in round 5, and BAC-1 won the championship on tiebreaks.

Last weekend, the U.S. Amateur Team Championship was held at the Santa Clara Convention Center, and if you are unfamiliar with this event, you are missing out on what is perhaps the most exciting spectacle in amateur chess. It is a team event, made up of 4-player teams whose average rating must be below 2200. This means that you may have a GM or IM on your team, but you must sacrifice so to speak some points on the lower boards to average under 2200. There are also section prizes for teams averaging under 2000, 1800 etc. there are also prizes for top club, top corporate team, best team name etc. The atmosphere for this event is incomparable, and this year’s version had high drama until the very last game.

There are similar competitions for the East, South, and North. The winning teams of these 4 regions compete in a rated championship finale online, held on a Saturday with a semi-final and final. I had the honor of being Tournament Director for last year’s semifinal for the San Jose Hackers, who won their semi-final, but fell just short in the finale.

I co-wrote the online article for the event with Judit Sztaray of Bay Area Chess, who organized this amazing event; you can read that report here.

I wanted to write in this newsletter about what it is that makes this event so special. I was there from the very beginning on Friday morning to the very end Sunday night. In all, 65 teams participating, so the total number of players was 275 including alternates. When you play in a team event like this, every game matters. You become emotionally invested not only in the games of your teammates, but those of other teams that you are competing with and might face later on. For those that are looking to compete and win, the drama is non-stop.

But there are also those teams made up of long time friends who use the President’s day weekend to play together and catch up on old times. Every year, a team made up of former UCLA classmates that include Mr. G Dan Gertmenian and Carey Fan of ChessKid.com come and play, trying after several years to win their section prize. Last year, they won best team name, which was voted by all the players themselves, with get this: Free Brownies for Everyone if We Win Best Team Name. Needless to say, they were far and away the winner, and they delivered in the last round, homemade!

Dan Gertmenian and his team delivered on their promise, baking an assortment of brownies that fed all 270 players at the 2018 U.S. amateur Team Championship

Speaking of schools, I was very excited to see four teams from UC Berkeley come and compete, including the only 6/6 score in the whole tournament from FM Teemu Virtanen. As a fellow grad, I had to sport my Cal sweater for the last day, and the teams performed very well. I won’t even ask what happened to Stanford this weekend, as they didn’t field a team. Even a UCLA brought two teams. Heck, Northwest University from Washington captained by Benjamin Mukumbya from Queen of Katwe fame brought a team!

FM Teemu Virtanen leading his UC Berkeley team Ultra-Cheesy Bread

Teams showed up wearing their high school team gear (Hopkins Hawks) or shirts representing their chess clubs (Berkeley Chess School, Bright Chess King). The team spirit and friendship really comes out in full force, and it is just a joy to see the unifying aspect of chess mixed with competition and camaraderie.

I want to leave this story with this note. You can read how the end played out for the tournament in the online article. The teams on the final day fought every game to the bitter end, and the drama was intense, as teams would shuffle out of their seats monitoring other games, trying to gauge results, trying to determine if they should play for a win or a draw. You see chess in its most exciting aspect when this happens, and team Captains have to be on the ball.

There was some disappointment for some teams. I want to give special recognition to Greg Lope from Berkeley Chess School, who fought bravely and desperately in the final round to save a draw in a complicated position despite being down a rook, knowing that saving the draw might have a significant impact on whether Berkeley Chess Schools’ team BCS Wu Hoo! would win the championship over BAC-1. I saw him concentrate, looking for that knockout opportunity, staying fully concentrated when many of us may have been frustrated and tuned out. Going into the 5th hour. As we all know in chess, it only takes one mistake to change the tide. Ultimately, his opponent Anirudh Seela finished the win in dramatic fashion with a nice tactic, and as it turned out, gave BAC-1 the championship on tiebreaks. I’m sure he felt the sting and disappointment, but he showed the heart of a lion, and it did not go unnoticed by me or his teammates. He won every other game he played in the tournament.

There were many other games like this. As with any team sport, one player and one game do not lose it for the team. You win as a team; you lose as a team, plain and simple. I really hope everyone remembers this, and come ready to fight on the next year.

Fair Play Rules

I’m going to take it upon myself to write about something no one else will, and celebrate honesty and fair play in chess and the courage of those speaking up for protecting the integrity of the game. Last year’s original Amateur Team West winner NorCal House of Chess was stripped of their title, after an extensive review by the U.S. Chess Ethics Committee. They were unanimously found to have engaged in rating manipulation to lower the ratings of their players to compete in the event, essentially qualifying much stronger players to participate and fall under the 2200 average. Those players and Captain were stripped of their USCF memberships and TD certifications. Kudos to the USCF for having a process and procedure in place to protect the integrity of the game, and kudos to those who went through the lengthy process of filing the complaint. The process is not quick, but the persistence in going through it and standing up against unethical play benefits each and every USCF member, and hopefully players will be more vigilant in coming forward if they suspect cheating. Please notify the TD if you suspect any wrongdoing in an event. TD’s are there to help and we want to keep the game clean for everyone.

Winter TNM Headed to Championship Round!

FM Kyron Griffith (white) faces off against NM Conrado Diaz on Board 1 in round 7

The 7th round of the Winter TNM saw the game everyone has been waiting for. FM Kyron Griffith (2458) faced off on Board 1 against tournament leader Conrado Diaz (2343).

Griffith gained a positional advantage early and used solid technique to convert the win. This game as well as all the others can be found at the end of this newsletter or online at the chess club home page chessclub.org.

On Board 2, Alexandr Ivanov converted an advantage in a rook and pawn endgame for a win against Steven Gaffagan and on Board 3, Natalia Tsodikova, down an exchange, took an advantage of a late blunder by Michael Walder to steal the win. Natalia always shows amazing concentration in her games, and her laser like focus carried her on to a victory.

We head to the final round next week with Alexandr Ivanov the sole leader at 6/7, with 7 players in pursuit with 5.5/7, including FM Griffith. The final round is sure to be action packed, as players go all out for a sprint to the finish. Can Ivanov hold on to his half point lead and claim the title? Tune in next week for the live action, as we will broadcast boards 1-4 Live!

A Walk in the Tournament Hall – Takeaways from the Chess World

by Darwin Li

Darwin Li is a member of the Mechanics Institute Chess Club and is a USCF expert. He played competitively since 7 years old up until high school. He was the winner of numerous Virginia scholastic state championships and the winner of the 8th grade K-12 / Collegiate Nationals in 2007. He graduated from Princeton University in 2016 and is currently working as an investment professional specializing in healthcare in San Francisco. He is currently working with the chess club in outreach and social engagement.

My hands begin to sweat. My thumbs are pressed against my temples and the rest of my fingers form an appendage visor around my hairline. I realize I’m shaking my leg as I become attuned to the high-pitched squeaking sound coming from my chair. I slowly extend my quivering hand over the board as I quickly scan for obvious signs of blunder. I nod to myself in reassurance, make the move, and slap the Chronos in one fluid motion. Out of instinct, I pick up my pen and look at my notation pad, but immediately discard both. I hadn’t recorded a single one of the last ten moves because I was under what every chess player has encountered at one point or another, time pressure.

As I look back on my career as a kid, I dare say chess and the experiences that came from it have been the most formative in my development into the person I am today. Take the example in the above paragraph, time pressure. Let’s say you’re playing a 40/2 SD/1; 6 hours have elapsed and you only have minutes if not seconds left on the clock. You’re exhausted, but you’re in a situation where one wrong move nullifies all the hard work leading up to this point. These all-too-common situations, which epitomize the often binary nature of important decisions, impart with players an invaluable and highly transferrable skill: the ability to act logically in a highly pressurized environment. Some say these situations teach a player to go with his/her gut. Going one layer deeper, I’d say time pressure teaches, from an early age, pattern recognition, risk analysis, and confidence. No two time-pressure induced positions are the same, but I’m able to apply heuristics and what has worked in other similar situations to quickly, accurately, and confidently execute on the position in front of me in a way that minimizes my risk, in terms of both position and time. For a competitive player, this is a skill that will be well-refined after multiple repetitions and incredibly useful outside the chess world. For example, in a professional setting – as a hedge fund trader that executes split-second million dollar trades, or a software engineer who codes algorithms and innovative solutions with tight project deadlines to name a couple examples – or in everyday activities such as driving a car or even responding intelligently and appropriately in conversations.

On a somewhat related note, chess teaches, more broadly, the ability to persevere in difficult and uncomfortable situations. I’ve come to find that almost never are games played in ideal conditions. Envision the following scenario: You lost the previous round to a lower rated player due a blunder you should not have made, the game lasted too long for you to grab lunch, and you’re dead tired from the insomnia you experienced last night for one reason or another. You sit down at your next game to find your opponent has an annoying sniffle and cough. Or even worse, you’re the one with the annoying sniffle and cough. Not to mention any personal issues you might be dealing with – at work, in school, or at home. While maybe in only the most unfortunate of circumstances would you be caught in the perfect storm exactly described as above, I’d argue it’s more common than not to be less than 100% for most, if not nearly all your games. It’s ultimately up to the player on how to deal with said adversity and maintain a winning mentality. While we all have our methods of coping (coffee, music, cold water on the face, self-massages), it goes without saying that the willpower, endurance, perseverance, and optimism chess indoctrinates go a long way outside the tournament hall. Chess creates winning mindsets.

While having to deal with time pressure and discomfort might be apparent and second nature to a competitive player, a less obvious, yet, in my opinion, the most important lesson chess imparts is that of sportsmanship and mental maturity. Chess very quickly (4 moves to be exact) taught me that you can’t win every game. There will always be someone out there with more experience, greater preparation, or better “luck.” More than anywhere else, to survive and succeed in the chess world, one learns to learn from mistakes and quickly come to terms with the prior round results, win or loss, as to not impact the performance of the following game(s). Chess has taught me that in life, paradoxically, it’s both okay and not okay to lose. It’s what you do about those losses that define who you are, as cliché as that sounds. Chess teaches you that it’s far more productive to treat setbacks as learning experiences and an impetus to continue improving, rather than an end-all-be-all, a doctrine to be applied in any context.

Along the same vein as sportsmanship, chess uniquely develops one’s social skills. Growing up, chess was the only environment where I dealt directly with people of all ages and walks in life. You walk into a skittles room and you’ll find a 12-year-old prodigy going over his last game with his septuagenarian opponent. You’ll find college students playing blitz with parents whose kids called winners for the next game. You’ll have a doctor, teacher, consultant, and poker player rapidly moving pieces, yelling some combination of “sit, go, plus plus, minus minus” in a heated game of 2-minute bughouse. Through the universal language of chess, players quickly gain exposure to vastly different backgrounds and perspectives and learn how to interact and socialize accordingly — a maturity otherwise not achieved from time spent in school, youth sports leagues, or the office.

While words can only capture a tiny fraction of the impacts of competitive play, it goes without saying that chess is not merely a board game with rigid and defined rules. I echo the sentiment of many players when I say that through its ups and downs, trials and errors, wins and losses; chess has had a profound and positive impact on my personality and outlook on life.

Friendly Rivalries, Part 3

by FM Paul Whitehead

Vincent McCambridge earned his IM title in 1982, wrote a book about his main rival Yasser Seirawan in 1984, and played in the 1985 US Championship. Vince served as an MI Trustee for many years, and was part of the winning Mechanics’ 2006 US Chess League team, the precursor to the PRO Chess League. Among his many successes over the board are a tie with MI Grandmaster-in-residence Nick de Firmian for 1st Place in the 1990 People’s Open in Berkeley.

Vince and I crossed swords four times, twice in 1977 as up and coming juniors, and twice in the 1980’s. We drew our last encounter, which was a surprise to me as I was out of form and behind on the clock, as well as having a bad tournament. But maybe “Vinnie” thought he had to break the jinx: I had bested him in our three previous encounters, and losing was going out of style. One thing’s for sure- the guy is tall, and he’s out to win. I always felt I had dodged a serious bullet after we played!

GM Nick de Firmian’s Endgame Lab

Marshall-Lasker Endgame

Fabiano Caruana was the first American in 46 years to play for the World Chess Championship. He lost that close match to Carlsen last November in the tie-break rapid games, not matching Bobby Fischer’s spectacular success in becoming an American World Champion. Before Fischer there was another championship contender in the 20th century. Frank J. Marshall was a brilliant player whom New York’s Marshall Chess Club is named after. Marshall had great tactical skills, but to be champion one needs to be a great endgame player. Marshall’s opponent in the 1907 World Championship was the great Emanuel Lasker, who relied many times throughout his career on his endgame skill for his tournament and match success. The following game from his 1907 match with Marshall is pure elegance of movement.

(1) Marshall,Frank James - Lasker,Emanuel [C65]
World Championship Match, 1907

1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.d4 exd4 5.0-0 Be7 6.e5 Ne4 7.Nxd4 0-0 8.Nf5 d5 9.Bxc6 bxc6 10.Nxe7+ Qxe7 11.Re1 Qh4 12.Be3 f6 13.f3 fxe5 14.fxe4 d4 15.g3 Qf6 16.Bxd4 exd4 17.Rf1 Qxf1+ 18.Qxf1 Rxf1+ 19.Kxf1

MARSHALLvsLASKER_115

After a complicated opening and middle game the players have traded into a materially equal endgame. There are six pawns each, with just a rook and knight for White and a rook and bishop for Black. Both sides have three pawn islands and Black has doubled c-pawns. It seems difficult to believe either side could have much of anything, but we see Lasker make superb use of his faster force to highlight the differences. 19...Rb8 20.b3 Rb5!

MARSHALLvsLASKER_116

Lasker leaves the bishop on c8 as it can immediately swing into action with just one move. The rook makes great use of the 5th rank — note 21. Nd2 Rc5 22. Nc4?! Ba6 would be awkward. Probably 21. Ke2 would be best. 21.c4 Rh5 22.Kg1 c5 23.Nd2 Kf7 24.Rf1+ Ke7

MARSHALLvsLASKER_117

The position has stabilized. White has finally developed his pieces while Black has gotten a protected passed pawn and more centralized king. The white e-pawn is also somewhat vulnerable and the black bishop has long term targets of pawns on the white squares. 25.a3 Rh6! 26.h4 Ra6 27.Ra1 Bg4! 28.Kf2 Ke6

MARSHALLvsLASKER_118

White is on the defensive and tied down. His position has become critical where it is hard to stop the invasion. 29.a4 Ke5 30.Kg2 Rf6! 31.Re1 d3! 32.Rf1 Kd4

MARSHALLvsLASKER_119

The infiltration of the black king spells the end for White. The advanced d-pawn, the superiority of the bishop against the knight and the weak b and e pawns are too much to live with. 33.Rxf6 gxf6 34.Kf2 c6 35.a5 a6

MARSHALLvsLASKER_120

No better is 36. Ke1 Kc3 and because of zugszwang White loses his pawns. 36.Nb1 Kxe4 37.Ke1 Be2 38.Nd2+ Ke3 39.Nb1 f5 40.Nd2 h5 41.Nb1 Kf3 42.Nc3 Kxg3

MARSHALLvsLASKER_121

Lasker efficiently mops up. The rest needs no comment. 43.Na4 f4 44.Nxc5 f3 45.Ne4+ Kf4 46.Nd6 c5 47.b4 cxb4 48.c5 b3 49.Nc4 Kg3 50.Ne3 b2 0-1


Robert Eugene Burger 1931-2019

Robert Eugene Burger passed away on February 6, 2019. He was a Trustee of the Mechanics’ Institute from 1982-1996, and was a college lecturer, chess master, chess reporter and author. During Bobby Fischer’s simul appearance at the Mechanics’ Institute in 1964, Bob Berger had a beautiful victory against him that can be viewed here.

His devotion to chess and to the Mechanics’ Institute will always be part of his legacy, and he will always be remembered among the legends that have been a part of this historic club.


The Silent Chess Genius: GM Albin Planinc (1944 - 2008)

By NM Derek O’Connor

The games of lesser known chess players have always fascinated me, and I recall coming across the well known game Rafael Vaganian - Albin Planinc played at Hastings 1974/1975, which features the following spectacular finish.

Black to move.

When I came across this game as a young chess player, it made a big impression on me. Looking into Albin Planinc’s other games, frequently featuring complicated and unclear sacrifices, I became fascinated about this grandmaster whose ferocity and daring sacrifices over the chessboard were a sharp contrast to his personality and life.

Albin Planinc was born in 1944 in Briše to a working class family. He learned to play chess at the age of 7 in school, and progressed with self study. In 1957, he started playing competitively and in 1961, he placed third in the Ljubljana Youth Championship. His first major successes came in 1962 when he won the Slovenian Youth Championship, which he followed by sharing equal third/fourth at the Yugoslav Youth Championship, after which he was awarded the title of candidate master.

His first international success came at the very strong 1st Vidmar Memorial held in 1969. The field boasted 10 grandmasters, 3 international masters, and 3 untitled players including Albin Planinc, who was allowed to play by the organizers as there were a few extra spots available. Although strong grandmasters such as Svetosar Gligoric, Wolfgang Unzicker, Aleksandar Matanovic, and Robert Byrne were favorites the win the event, Planinc caused a sensation by scoring +7=7-1 to finish with 10.5/15 for sole first place. There are many great games of Planinc from this event including a stunning rook sacrifice as white against Matanovic in a Sicilian middlegame, and his final round win against Florin Gheorghiu where he turned down two draw offers and again sacrificed his rook for a winning attack. Both games are worthy of study and analysis, but for the sake of brevity I have limited myself to his two best games.

Planinc’s performance at the Vidmar Memorial was strong enough to satisfy the FIDE requirements for the Grandmaster title at the time, but he was only awarded the title of International Master as players could not be awarded the Grandmaster title without first obtaining the International Master title. At the time of the Vidmar Memorial, Planinc was working at the Rog, a bicycle factory in Slovenia, but following his success, he received invitations to play in prestigious tournaments in Čačak, Serbia and Skopje, Macedonia. As a result, he was able to quit his factory job and devote himself fully to chess. In 1972, FIDE awarded Planinc the Grandmaster title, and in 1973, he achieved his best ever tournament result, finishing with 10/16 and tying for 1st with Tigran Petrosian at the powerful IBM Amsterdam chess tournament, ahead of Grandmasters Lubomir Kavalek and Boris Spassky.

According to Hans Ree, Raymond Keene, and other grandmasters’ written accounts, Albin Planinc was a very reserved and timid person, a man of few words who spoke mainly to analyze chess. Sadly, he suffered from depression and likely other undiagnosed mental health issues, and it is possible that the strain of playing chess tournaments at a high level contributed to his mental decline. His results began to suffer noticeably around 1975/1976, when he started finishing in the middle to bottom of the standings in tournaments. Planinc played his last major tournament in 1979 — the 17th Rubinstein Memorial. After spending some time in a psychiatric clinic in Ljubljana, he settled in an assisted living facility with his mother where he lived out the remainder of his life, excluded and in poverty.

Although Planinc’s life story is a tragic one of hardship and unfulfilled potential despite his enormous talent, he is remembered by his fellow grandmasters as a fearless attacking player with creative and beautiful ideas. One such Planinc specialty that interested me was his handling of the Arkhangelsk Defense: 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O b5 6. Bb3 Bb7 (which has been mostly replaced by the Modern Arkhangelsk Defense where black plays 6… Bc5). Several of his victories in this line are so stunning that his win over Vaganian pales in comparison — what is most impressive in these games is Planinc’s ability to make long term sacrifices that require incredible nerves to play because they simply cannot be calculated all the way to the end. I would like to finish the article by presenting what I consider to be one of his finest victories from this very opening.

Dragoljub Minic - Albin Planinc played at Rovinj/Zabreb 1975

Black to move.

What would you play here? I think most players would choose the relatively staid 12… Nc5 13. Bd5 Bxd5 14. Qxd5 Rd8 with a messy but roughly level position.

Planinc played a truly astonishing move showcasing his characteristic ingenuity and brilliant intuition. 12… O-O-O!!?

This move looks crazy, but it soon becomes apparent that black will sacrifice his queen and rely on the passed d-pawn for counterplay. 13. Nxe4 Qxe5 14. Re1 f5

15. Qg3 White keeps the piece, or so it seems! 15… Qe8! 16. Nd6+ Bxd6 17. Rxe8 Rhxe8

How should white defend here?

18. Bf4?! It is perhaps a bit unfair to criticize this move, as white could hardly have been expected to see the sequence awaiting him, and what could be more natural than simultaneously developing and defending? 18. f4! is best but after 18… Bc5+ 19. Kf1 Re2 20. Bd1 Bxg2+ 21. Qxg2 Rxg2 22. Kxg2 ± white emerges better with a bishop for three pawns in a highly unbalanced ending. I should also point out that 18. Bf4 certainly looks more ambitious than giving the queen back with 18. f4, but I have the feeling Minic wanted to refute the sacrifice!

18… d2 19. Rf1 Re1 Now what does white do? Black has ideas of ...Rde8 and ...Bd5 in the air.

White to move.

20. Bxd6?! Again, white is understandably ambitious but despite the huge material deficit for black, his far advanced d-pawn and mating threats are extremely serious. 20. Qh4!! is both difficult to spot and psychologically tough to play because 20… Re4 threatens to win a bishop, restoring approximate material balance. The only way for white to hang onto the piece is by playing 21. g3 after which there might follow 21… Bxf4! 22. gxf4 Re1 23. Bd1 Rde8 24. f3 Rxf1+ 25. Kxf1 Re1+ 26. Kf2 Rxd1 27. Ke3 Bxf3 28. Qxh7 Be4 29. Qxg7 Rb1 30. Qh8+! Kb7 31. Kxd2 Rxb2+ 32. Ke3 Rxa2 33. h4 Rh2 34. h5 a5 35. h6 a4 36. h7 a3 37. Qe5 Rxh7 38. Qxb5+ finally reaching a draw by perpetual! This sample line is out of the scope of the article, but fun playing through and worth analyzing on your own.

20… Rde8! Now black threatens ...Bb7-d5-c4. 21. f3 Bd5

White to move. Notice how many critical moments there are for white here! Spirited attacking play by black forces white to walk a tightrope to defend.

22. Qf4? White tries to round up the d-pawn but this fails tactically. 22. Bf4! was correct when after 22… Bc4 23. Bxc4 d1=Q 24. Bd3 Rxf1+ 25. Bxf1 Re2 ∓ black is better but not clearly winning.

22… Bc4 23. h4 Rxf1+ 24. Kh2 Re2 25. Bxc7 Rff2

White to move.

The situation has worsened considerably and now white has only one move to not lose immediately. 26. Qd6? 26. Bd1! was the only try, and in his analysis, Minic thought he could survive here, but black still comes out on top with the accurate 26… Rxg2+ 27. Kh1 Bd5! which switches over to targeting the f-pawn. 28. Bb8 Rh2+ 29. Qxh2 Bxf3+ 30. Kg1 Rxh2 31. Kxh2 Bxd1 32. Bf4 Bb3 A nice touch so that black does not simply drop the d2 pawn. 33. Bxd2 Bxa2 -/+ and with three healthy extra pawns, black should win the opposite colored bishop ending. 26... Rxg2+ 27. Kh3 Rh2+ 28. Kg3 Reg2+ 29. Kf4 Rxh4+ 30. Kxf5 Rh6 0-1

The final position is a picture of perfect coordination and domination by the black forces over the white queen and bishop pair. A sparkling gem of a game to commemorate Planinc’s relatively brief but shining chess career.
