FIDE’s First World Amateur Championship Match

Bogoljubow

    Founded in 1924, FIDE soon started trying to organize the World Championship, but two years earlier Capablanca, the World Champion from 1921 to 1927, had set the conditions under which he was willing to play for the Championship. Those conditions were far beyond the resources of the fledgling FIDE. 

 Consequently, Alexander Rueb, FIDE’s president, then had the idea of creating a separate championship to be named the FIDE Championship. And so, in a letter sent to Max Euwe and Ewfin Bogoljubow he proposed that the winner of their match would become FIDE Champion of FIDE. 

    Their decision was based mainly on the fact that the 1928 World Amateur Championship that was held in Amsterdam had been won by Euwe. Also, at that time Bogoljubow was one of the top 3 or 4 best players in the world. 

    The match generated a lot if enthusiasm in Holland and Bogoljubow scored a narrow victory, scoring +3 -2 -5. Them after the match a wealthy sponsor finance a second short revenge match that was also won by Bogoljubow +2 -1 =7. 

    The following is game 4 of the first match is replete with imaginative and forceful play on Bogoljubow’s part. Queens were exchanged in the opening, but that didn’t cut down on the aggression shown by Bogoljubow. The tension mounted until ay the critical moment and Euwe went down the wrong path and was never able to recover

Bledow’s Queen Sacrifice at move 8

    Happy Birthday Dr. Ludwig Erdmann Bledow (July 27, 1795 - August 6, 1846).  He was a German master and organizer who was the co-founder of the Berlin Pleiades, a group of several German masters and in 1846, he founded the first German chess magazine, Schachzeitung der Berliner Schachgesellschaft. Later it wa renamed Deutsche Schachzeitung. 

    In those days some of the game’s moves and competition rules had not been universally agreed upon, For example, Bledow believed that a player should be allowed to have multiple Queens when promoting Pawns. He also argued in favour of the touch-move rule. 

 In 1848, about two years after Bledow’s death, a letter he had wtitten to Tassilo von der Lasa proposing that an international tournament should be organized was published. His idea was that the winner would be recognized as the world champion. In 1851, the surviving members of the Berlin Pleiades nominated Adolf Anderssen to represent Germany at the London 1851 tournament. As winner of the tournament Anderssen was widely recognized as the world's strongest player. 

    It’s difficult to say exactly how strong Bledow was, but in the mid-1800s he defeated some of the best players around in match play, including the 27-year old Adolf Anderssen by either 5-0 or 4.5-0.5, depending on the source. According to Chessnetrics there is no rating for Bledow and Anderssen’d estimated rating in 1848, three years after the match) was only in the mif-2400s, considerably below his 2600+ rating in the early 1850s. 

Dr. Ludwig Blewow

    As for his playing style, Bledow was described as preferring closed positions and not a "heroic" player. His surviving games support that claim, but the following game featuring a Queen sacrifice on move 8 is a pleasing exception. 

    His opponent was Paul Rudolph von Bilgur (1815-1840, 24 years old) a German master and theoretician. von Bilguer, who was a lieutenant in the Prussian army, resigned his commission and devoted his time to chess. 

    He was considered to be the most brilliant of the 'Pleiades' players. He is best known today as the co-author of the Handbuch des Schachspiels. He died at age 24, probably of tuberculosis, before finishing the Handbuch, but the work was completed by his friend Tassilo und der Lasa, who gave primary credit to Bilguer. The book was a reference book, particularly om openings. 

    While this game is far from perfectly played, Bledow;s Queen sacrifice will leave you gasping.

Seidman Sets a Snare

    The Intercollegiate Chess League has a long history dating back to leagues like the Quadrangular Intercollegiate league (Harvard, Yale, Columbia and Princeton) in 1892. In 899, thr Triangular Intercollegiate League (Cornell, Brown, and the University of Pennsylvania) established their own triangular league. These laid the foundation and the Pan American Intercollegiate Team Chess Championship, established in 1946, became a major annual event. 

    Today’s game was played in 1938, in a collegiate league in New York City made up of two teams from the Central College of New York, Brooklyn College, two teams from New York University and Yeshiva College. 

    In 1938, the title and custody of the Harold M. Phillips trophy was won on a 4-0 forfeit by a team from C.C.N.Y when the team from Yeshiva College failed to appear at the Manhattan Chess Club for the last match. This was on a Sunday after Saturday’s match had been rescheduled to accommodate the Yeshiva players who could not play o the Sabbath. 

    The Tournament Director, Harold Sussman, who was also the newly elected president of the league, gave the Yeshiva team until noon to appear and when the didn’t they were forfeited. The winning C.C.N.Y. tam consisted of Jack Soudakoff, Sava Jacobson, Milton Finkelstein and Samuel Rubin. 

 

 

    The game's winner, Herbert Seidman (1920-1995) was a Senior Master (rated over 2400) who was born in New York City. At his peak, he was ranked among the top ten players in the country. Seidman played in eight U.S. Championships between 1940 and 1968. 

 His obituary informs us that Jack Soudakoff was born in Russian and on Novmber 19, 2005, at the age of 87, he peacefully passed away surrounded by his beloved wife Bea, sons David and Alan and a future daughter-in-law Diane. Soudakoff was a edicated family man, WWII vet, longtime New York Subway systems analyst. 

    In the early middlegame Seidman had a modest advantage when, at move 20 instead of playing the obvious move, he laid a snare and Soudakoff got caught.

Gelfand’s Anti-Masterpiece

    The 2012 World Championship natch between the defending champion Viswanathan Anand and challenger Boris Gelfand was held in Moscow. The prize fund was approximately 2.5 million dollars. It was foe 12 games. In case of a tie, first rapid games, then blitz games, and finally an Armageddon game if needed, would br played. 

    After the first six games the match was tied after six fairly short draws. Gelfand won game 7, but the next day Anand won game 8 when Gelfand managed to get his own Queen trapped in a miniature that is the shortest decisive game in World Championship history. It’s today’s featured game. 

    Then after four draws, the match headed into overtime. Anand was famous for his prowess in rapid and scored +1 -0 =3 in the rapid games to retain his title.play,

    The day before this game Gelfnd had produced a strategic masterpiece by Gelfand and it left some profits predicting that Anand’s days as World Champion were numbered, but they turned out to be false prophets when Gelfand produced this anti-masterpiece that lasted only 17 moves and 110 minutes.

A Rook Offer Black Couldn’t Accept or Refuse

 

    In 1965, people were seeing were seeing changes in music, fashion and television. The British Invasion continued with groups like The Beatles and The Rolling Stones growing in popularity, Fashion saw the miniskirt and television offered a mix of wholesome family sitcoms and superhero like Batman. 

    The chess scene was highlighted by the Candidates Matches, a series of knockout matches to determine the challenger for the World Championship. The players were Spassky, Keres, Geller, Smyslov, Tal, Portisch, Larsen and Ivkov. Spassky won by defeating Keres, Geller and Tal. 

    Bobby Fischer didn’t participate because of his decision not to play in the 1964 Amsterdam Interzonal, the qualifying event. The disgruntled Fischer had previously accused Soviet players of collusion in the 1962 Candidates Tournament, an 8-player event where Fischer had finished 4eeth behind Petrosian (the winner) and Keres and Geller (tied). His accusations were well founded. 

    As a result, FIDE changed to the knockout matches, but, being the snot face he was, Fischer wasn’t satisfied. He still didn’t like the format and demanded specific playing conditions. 

 The Soviet Championship was won by Leonid Stein and veteran Soviet and renowned endgame composer Vitaly Chekhove passed away. 

    Fischer did play in the 1965 US Championship and won it even though he lost to Robert Byrne and Samuel Reshevsjy and was held to a draw by William Addison. He still finished a point ahead of Byrne and Reshevsky who were tied for second; Addison was 4th. 

 Up in Canada the veteran GM Dan Yanofsky of Winnipeg won the Canadian Championship over a strong 12-man field in Vancouver. There were several interesting games, including this one in which Duncan Suttles (born in 1945) defeated Joseph Kalteneck. 

 

    Suttles was born in San Francisco and his family bed to Canada when he was 8 years old. He was awarded the GM title in 1972 and retired from chess shortly thereafter to work on stock market analysis. Suttles was known for his unorthodox treatment of Hypermodern openings. In this game he conducts a vigorous attack straight out of the opening and finishes with a nifty Rook offer that could neither be accepted nor declined.

A Nice Finish by Carlos Guimard

    In 1938, tensions in Europe were escalating and growing Nazi aggression dominated world events. In the U.S. things were heavily influenced by the Great Depression and the looming threat of war. 

    In pop culture radio programs like the comedy Amos 'n' Andy, soap operas and sporting events were popular. Hollywood movies, including musicals and gangster pictures, provided entertainment Also, comic book, like Superman, were beginning to appear. 

    It was the year Orson Welles' War of the Worlds was broadcast and it caused widespread panic as some listeners believed the alien invasion was real. 

    In South America there was a a complex web of political, economic, and social shifts, largely influenced by events in Europe and the looming threat of World War II. 

    In Uruguay the situation was no different. General elections were held, resulting in the subsequent presidency of Alfredo Baldomir, a soldier and architect who served as President of Uruguay from 1938 to 1943. 

    Montevideo was the scene for the eighth South American Championship (Torneo Sudamericano) that took place in March. Alekhine was undefeated and finished 1.5 points ahead of Carlos Guimard. The other players were mostly known only in South America. The event was actually held in an elegant seaside resort Carrasco, one of the most expensive neighborhoods in Montevideo. 

    The featured game today has a nice finish. The winner was Carlos Guimard (1913-1998, 85 years old) of Argentina. He was awarded the GM title in 1960 and was he was Argentine champion in 1937, 1938 and 1941.

 

    His opponent was an Argentine National Master. Bensadon played aggressively, jis N on d5 cancelled out Guimard’s two Bs as both sides attacked their opponent’s King. The, right when things were looking drawish, Bensadon struck a snag when he miscalculated the strength of his passed e-Pawn and sacrificed his B in order to Queen it, but Guimard blocked the P and was left a piece up.

Reshevsky Owned the e-file

    The 1972 Chess Olympiad was held in Nice, France and saw the Soviet Union (Karpov, Korchnoi, Spassly, Petrosian, Tal and Kuzmin) took forst, finishing ahead of Yugoslavia (Gligoric, Ljubojevic, Ivkov, Planinc, Velimirovic and Parma.) The United States (Kavakek, Robert Byrne, Browne, Reshevsjy, Lombardu and Tarjan) finished third. 

    In the following game from the US vs. Sweden match in the Final A group the dominant factor was Reshevsky’s control of the e-file. Playing black, Reshevsky opened with the Benoni Defense which morphed into a King's Indian. 

    Udderfeldt failed to get anything out of the opening and Reshevsky hit on an idea on move 14 that he said seemed to surprise Udderfeldt who then made what Reshevsky called a “peculiar reply.” 

    Reshevsky gained control of the e-file and the game was practically over as the activity of his pieces kept increasing until his opponent was reduced to complete passivity. 

    It was a fine demonstration of putting the squeeze on an opponent, but a careful examination shows that it wasn’t the positional rout Reshevsky’s notes suggested. Udderfeldt missed some better defenses, but the game demonstrates the difficulty of defending a position with no real hope of counterplay. All that said, I consider the game was still a positional masterpiece by Reshevsky.

    Dan Uddenfeldt (born in 1951),is a Swedish master who was one of the leading players in Sweden in the 1970s when he participated in several international junior championships.

Engine Analysis Then and Now

    When browsing some of my old server games I came across the following very difficult game that was played on a site where engine use was allowed. When it was played in 2011, Rybka was the strongest engine, but it was later disqualified from the World Computer Chess Championship and stripped of all titles for plagiarism. 

    That meant Houdini was next in line as the top engine, but Rybka’s disqualification opened up opportunities for other engines like Stockfish to rise in prominence. Fritz was also a well-known engine in 2011, but it was generally considered weaker than Rybka and Houdini. Overall, by this time engines had become significantly stronger than human players with the best engines exceeding 3000 Elo. 

 In those days I only used the free engines and there were several strong free and open-source engines available. Stockfish was one of the most widely used. Houdini 1.5a was another extremely strong engine as was Rybka 2.3.2a. Critter, Gull, Protector and Crafty were also very strong free engines. 

    Many of these engines could be used with free graphical user interfaces such as Arena and Scid, but I was using Fritz 12. It was released in November of 2009. I don't remember the cost, but I found the program in a long defunct office supply store whose name I have forgotten, but not the price. I bought the CD for $20 which was a fraction of the price from the USCF. It was my go-to program until I replaced it with Fritz 17 in 2021. It's still on my laptop and I actually use it to conduct Shootout analysis because it works better for that than the newer Fritz programs. 

    When playing the following game I used several different free engines and on occasion felt they were suggesting less than optimal moves. In my old post-mortem analysis it was very difficult for me to determine what the best moves were, but my feeling was that black missed several chances to draw.

    Black’s trouble seemed to stem from the decision at move 52 to trade his two R’s for my Q and a P. Despite the engine evaluations giving white a nearly 3 Pawn advantage, my gut feeling was that by keeping the R’s on he would have made it much more difficult for me to squeeze out a win. 

    All that is moot because today it’s clear that he was already dead lost at move 52 and he had a bad position for many moves before that. It was interesting to analyze the game using today’s Stockfish and comparing it to the old free Rybka engine.

Fritz 20

 

    First, let me say I have no financial interest in this product. As most readers are aware, I have been a fan of the Fritz program for years and not too long ago upgraded to Fritz 19 from Fritz 17. 

    There was not too much difference between the two for my purposes because I do not play against the program for fun and any idea about using it for improvement is out of the question. 

     According to reviews some users had some bug issues with Fritz 19, but I have not run into a single problem, at least not with the feature I use. 

    Now Fritz 20 is available (download from the USCF costs $77). The first thing I noticed is that the user interface has been redesigned. The new design is supposed to be “modern” and visually aesthetic. I don't like it, but that’s probably because it’s not what I am used to after all these years. They have also changed the 3D boards, but I never use them so for me it’s a moot point. 

    The major changes are in the area of playing for fun. They have added three modes for you to play against: Hypermodern, Robot and VIP.  In the Hypermodern mode the program uses flank openings. In the Configurable mode you can adjust various characteristics of the opponents. Most intriguing is the VIP mode that allows you to play against opponents like Fischer, Tal, Karpov, Capablanca and Lasker. These opponents play with the style of the player and use their opening repertoires. Watch this Youtube video

 

Conclusion:

    For Bloggers looking to publish games, average players looking to improve or just have fun, Fritz 20 is a fantastic program that is well worth $77. 

    If, like me, you are no longer looking to improve or you prefer meeting real live opponents online or you just want the basics like publishing games, analyzing, playing over games or using basic database functions then an earlier version, if you can fine one, will suit you just fine. If, on yhr other hand, you are looking for a program that is just plain fun to tinker with then you can;t beat Fritz 20.

A Solid Performance by Tal

    Former World Champion Mikhail Tal (1936-1992, 55 years old) was noted for his brilliant sacrifices which were often base on intuitive thinking and his ability to calculate variations. 

    The following game shows another side of Tal’s play; there is no flashy tactics, subtle positional play or brilliant endgame play...just a rock solid performance. It shouldn’t be surprising that Tal could play something other than tactical chess because no player is going to become world champion with a one sided style. The intuitive sacrifices he was famous for were a personal preference. 

    In this game that was played in World Student Team Championship that was held in Uppsala, Sweden, in April 1956, Tal play was nothing flashy, just solid chess. 

    The Soviet team won the tournament with Hungary taking second place. The Soviet team won convincingly, notably defeating their main rivals, Yugoslavia, in the early rounds. Yugoslavia and Bulgaria tied for third. The United States team finished eighth. 

    Tal’s opponent was Borislav Ivkov (1933-2022, 88 years old). He was born in Belgrade, Yugoslavia and was awarded the GM title in 1955. Ivkov won the Yugoslav Championship in 1958 (tie), 1963 (tie) and 1972.

Najdorf Spits the Hook

    In the following game Najdorf played the opening poorly, got a bad position, then got lucky when Rellstab missed the best move and completely collapsed. 

    For some players this game might reinforce the “never resign” philosophy. I play occasionally on Chess Hotel and often run into poor sports (that’s the kindest way I can think of to describe them, but other words come to mind) who, when they are badly lost will not move and let their time expire even if it means sitting there for several minutes, or rather than resig, they just leave the game. 

    Almost as bad are those who play on to the bitter end no matter how much material they are down. Sometimes that is justified if your opponent is very short of time and he may not be able to mate before his time expires. It’s an ugly way to win, but time limits are a part of the game. 

    One reason for not resigning a bad position though might be because you are playing a much weaker opponent who might be prone to making a blunder that allows you to salvage the game. That’s what happened to Najdorf here. 

    That’s not to imply that Ludwig Rellstan (Senior) (1904-1988) was a weak player!. Far from it. In his day (the late 1930’s and 1940’s) Chessmereics estimates his rating to have been near 2600 which put hime in the world’s top 25 or so players. Rellstab won the German Championship in 1942 and was awarded the International Master title in 1950. He was also an International Arbiter. His son, a Jr., was born in 1935 and his last FIDE activity was in 2001 when he was rated in the 2100 -2200 range. 

 

    When this game was played Najdorf was one of the top players in the world, at least in the top ten, so it’s natural that he wasn’t going to resign a bad, but not lost, position. The position was complicated and Rellstab had a wide choice of possible moves and he chose the wrong one and Najdorf got away.

A Seesaw Battle

    My knowledge of players only goes back to Siegnert Tarrasch because I had Fred Reinfeld’s excellent book on Tarrasch’s best games. Steinitz, Staunton and Morphy are familiar names, of course, but not their games. 

    I confess to having no knowledge of the players of today’s game. The loser was Hyacinthe Boncourt (1765? - 1840), who was one of the leading players in France between 1820 and 1840, but not much is known about his life. Even the date of his birth is uncertain. 

    Boncourt was a contemporary of Philidor, but the two never played because the latter hademigrated to England and although Boncourt traveled around Europe, but he never visited London. He was a civil servant, and chess was mostly a hobby for him. 

    Pierre de Saint-Amant (1800-1872) was a regular player at the Cafe de la Regence and studied under Alexandre Deschapelles and Schlumberger. He was the editor of the chess periodical Le Palamede. Whilst visiting England in 1843 he lost a casual match to John Cochrane (+4 -6 =1) and defeated Howard Staunton (+3 -2 =1) in a casual match. Later u 1843, he lost a formal match to Staunton (+1 -6 =4). 

    Note: I came across this game in an old chess book that was published in 1952. The book and the author will remain anonymous because while the games themselves are interesting, the annotations are atrocious. Still, the games was a tremendous seesaw fight.
