Two Who Gave Up Chess

    
The following game was played by two great, but relatively unknown, players from a bygone era, both of who, gave up chess. The game was played in the 1955 Gothenburg Interzonal.The top nine players qualifying for the Amsterdam Candidates that was held the following year, 
    From 1955 until 1962 Dr. Miroslav Filip (1928-2009) qualified for the candidate tournaments twice. Filip's play was characterized as serious, solid and deep. Outside of chess he had no problem with the Soviet invasion of his country in 1968 and remained loyal to the authorities and managed to do very well. 
    Filip did not have a fanatical enthusiasm for chess and in 2002 he was invited to attend festivities for the 40th anniversary of the 1962 Candidates Tournament (im which Filip had finished last) that was held in Curacao, but he declined, saying he had pretty much lost interest in chess. 
    After a promising beginning his opponent in this game, Andrija Fuderer (1931-2011), ended up abandoning the game for his real passion, chemical engineering. His swansong was the 1959 Soviet Union vs. Yugoslavia team match where, at the age of 28 he showed what might have been by beating Bronstein, the victor at Gothenburg, by a score of 3-1. 
 

    In the late 1960s Fuderer left Yugoslavia for good, living in Spain and working as a chemical engineer in Antwerp. He only played in tournaments outside Yugoslavia in order to acquire consumer goods that he could sell when he returned home and use the profit to finance his university studies.

A Fischer vs Geller Encounter

    
Yefim Geller (1925-1998) was born in Odessa, Ukraine and died in Moscow. From the end of the Second World War until the early 1970s Geller was among the elite group who missed out on the world championship despite the fact that he was undoubtedly among the world's top ten players for over 20 years. 
    Take a look at his record against the world's leading players: Mikhail Botvinnik (+4 -1 =7), David Bronstein (+5 -4 =12), Tigran Petrosian, (+5 -3 =32), Vasily Smyslov (+11 -8 =37). 
    Against Mikhail Tal his record was +6 -6 =23.The only players against whom he did not fare well were Viktor Korchnoi (minus 5), Boris Spassky (minus 4) and Lajos Portisch (minus 2). Among his most interesting encounters were those against Bobby Fischer. Geller scored 5 wins, three losses and only two were drawn. 
    At Skopje, 1967, Fischer lost his third game in a row to Geller prompting Yugoslav GM Bojan Kurajica to write that Fischer just couldn't play against Geller. Yugoslav, GM and journalist Dr. Petar Trifunovic opined that Geller was in no way inferior to Fischer when it came to opening preparation and Fischer chose to play sharp opening variations because he was always playing to win. 
    In this game Fischer succeeded in outplaying Geller in the opening, but his play was tactically flawed and Geller, who was a superb tactician, was quick to take advantage of it. 
    Fischer had just recently come out of hiding and Skopje was an important warm-up for his participation in the Sousse Interzonal later in the year. As it turned out, Sousse was to become famous because of the Fischer Affair. 
    The tournament schedule was modified to fit Fischer and Reshevsky's religious obligations. After a dispute with the organizers over scheduling Fischer walked out while he was leading. 
    After nine rounds at Skopje he was tied for first with Russia’s Ratmir Kholmov. It was at that point Fischer once again revealed himself to be the loathsome snot face he really was. He announced he would withdraw from the tournament unless the chess sets were vhanges and the spectators were removed from further rounds. 
    The organizers could not meet the second demand so Fischer forfeited his tenth round game against Yugoslav master Milorad Knezevic who then showed he was quite a sportsman when he didn't want to accept a free point and allowed the game to be re-scheduled. After that, Fischer found his form and went on to finish first by a half point ahead of Geller and Milan Matulovic.

A Real Humdinger by Spassky

    
Humdinger: an informal, colloquial American slang term used to describe a person, object, action or event that is remarkably excellent, extraordinary or stands out above the rest. This game was a humdinger.
 
    Bobby Fischer called this game one of the ten greatest of all time. Czech GM LudekPachman called it a modern masterpiece. GM Andy Soitis ranks it number 32 on his top 100 list. A poll of readers by the Russian chess magazine Shakmatny Bulletin ranked it as one of the very best games of the 1960s. In his book on Spassky, Bernard Cafferty called it one of the finest games he had ever had the pleasure to review or to analyze. Everybody agrees that it is one of the most amazing games ever played and one of the more famous games of the modern era.
    The game is Spassky vs. Bronstein from the 1960 USSR Championship. It's the game that was featured in the classic James Bond movie "From Russia, With Love" as being played by Kronstein against McAdams. I never saw the movie because I am not James Bond fan and rarely watch movies. The game may not be perfect, but as Soltis pointed out, chess isn't always about finding perfect moves. (That is unless you're a modern correspondence player seeking perfection by using a n engine and a powerful computer). In OTB play chess is about making pragmatic choices. In this game Bronstein was short on time and the complications as a result of Spassky's sacrifice resulted in, as Botvinnik used to put it, head whirling complications. 
    If you haven't seen this game, you'll enjoy it. If you have seen it before, enjoy it again! If you want to play over the game on your own software you can download it HERE.

Tolush and Konstantinopolsky Slug It Out

    
Alexander Konstantinopolsky (1910-1990) was a Soviet player and David Bronstein’s traimer from a young age. He was awarded the IM title in 1950. He won the first Soviet Correspondence Championship in 1951, earned the Correspondence IM title in 1966, and was awarded the Russian title ofHonorary Grandmaster in 1983. 
    Konstantinopolsky was nearly 20 when he learned chess and at the beginning of his career hewon the Kiev championships five consecutive times from 1932 to 1936. 
    During the late 1930s, Konstantinopolsky trained young players and amateurs in Kiev, at the Palace of Young Pioneers. He was widely regarded as a friendly and kindly man. During the 1930s he, along with Bronstein and Isaac Boleslavsky, were the Ukrainian pioneers who developed the King's Indian Defense. He was also an early advocate of the Yugoslav Attack against the Dragon Variation of the Sicilian Defense, a line which would become very popular about 20 years.
    His opponent in this wild tactical game was the attacking genius Alexander Tolush (1910-1969) who was born in St. Petersburg. He was warded the IM title at its inception in 1950, the GM title in 1953 and the Correspondence IM title in 1965.

41,573

    
The number 41,573 refers to the LEGO Mixels Sweepz Building Kit available on Amazon for about $69. Or, it could refer to a 41573-84 Harley-Davidson OEM Rear Axle Adjuster for 1984–1996 FLT model motorcycles. You can get one for about $25 on e-bay. Or, it could refer to game number 41,573 in my games database. You can get it here and it’s free. 
    For the past few days I have been cleaning up the hard drive on my laptop because it was running out of space. The process involved deleting old files and programs and transferring files to a hard drive salvaged from an old laptop. 
    In the process ChessBase 16 came in handy for combining several databases into one, especially since some of them were in pgn format. ChessBase's proprietary CBH (ChessBase Header) files are significantly more efficient than pgn (Portable Game Notation) files because they use a lot less space. For example, a 1GB pgn database file could possibly be reduced to under 150-200MB. CBH files also allow faster searches and they support embedded multimedia (e.g. sounds, videos, colored arrows, training questions) that pgn can’t. 
    The game number was selected because when I checked the Blog there had been 6,042,573 visitors. The game was played in the Olympiad that took place in Moscow in 1956. It was won by the Soviet team (Botvinnik, Smyslov, Keres, Bronstein, Taimanov and Geller) ahead of Yugoslavia and Hungary.. The US did not send a team, 
    Toivo Salo (1909-1981) was a hree-time FinnisChampion (1938, 1949 and 1956). From the late 1930s to the early 1960s he was one of Finland's leading players. Ingi Johannsson (1936-2010) won the championship of Iceland four times (1956, 1958, 1959 and1963). From the mid-1950s to mid-1980s he was also one of the leading Icelandic players. 
    Salo was doing pretty good conducting a K-side attack, but misplayed it and allowed Johannsson to equalized. But then on move 28 Johannsson made a huge tactical blunder and it was all over.

A Lesson On the Initiative

Belavenets
    
The Russians Play Chess by Irving Chermev is a collection of 50 great attacking games from the years 1925-1945 (in my 2nd edition there are 6 games additional games by Bronstein, Smyslov, Tal and Petrosian, from 1951-60). 
    Most of the games are short sacrificial affairs and many are by lesser-known, or long forgotten, players of a bygone era. The real problem is that Chernev was not a Master and his motes are superficial at best. Another annoying habit, like his contemporary author Fred Reinfeld, is that the events and dates are not given. For example, in today’s game the event and location were not given, but I was able to locate that information. Unfortunately all of the games and the final standings are not available. 
    There is a diagram every few moves, so you can read it without a board. This means you could use the book for an unsystematic book on tactics, but the best thing is just playing over he games for enjoyment. 
    Although his analysis is frequently wrong, Chernev makes frequent comments so you aren't left in the dark about what's going on for long stretches of the game. Chernev tends to focus on threats more than anything else which helps in making it a good way to study tactics. 
     One review complained that the games are not of the same quality as those of better players, say Alekhine, Tal or Fischer. Maybe not, but that's the beauty of them! We see the mistakes, sometimes crude ones, that we will run into or make ourselves. 
    Here is one game I especially enjoyed. The winner, Sergey Belavenets (1910-942) was a Soviet master, theoretician, and chess journalist. He was born in Smolensk to a noble family. He and Mikhail Yudovich, known as the Smolensk twins, had been close friends since meeting in a school match in 1925. 
    Over the next few years they studied with Belavenets's uncle, Konstantin Vygodchikov, a master who enjoyed success in many very strong local Soviet tournaments. He was awarded the Soviet Master title in 1929 after tying with Botvinnik in the preliminary round of the USSR Championship. 
    Belavenets was in the Soviet Army and was killed in action while fighting at Staraya in 1942. His daughter Liudmila (born 1940) held the title of women's world correspondence champion from 1984 to 1992. 
    In this game white chose an opening line that allowed black to seize the initiative. Defining the initiative is sometimes a little slippery. It's usually defined as an advantage belonging to the player who can make threats that cannot be ignored.   
    Having the initiative puts the opponent in the position of having to use his moves to respond to threats rather than executing his own plans. The one who possesses the initiative can maneuver his pieces into more and more aggressive positions which will ultimately result in a strong attack. 
    Evgeny Zagoryansky (1910-1961) was born in Yerevan, Armenia. He frequently competed in the Moscow Championships. He authored The Story of Morphy, the life and fate of a chess genius.

The Immortal Losing Game

 
    
Bogdan Sliwa (1922-2003) of Poland was awarded the International Master title in 1953, and the Honorary Grandmaster title in 1987. He won the championship of Poland six times. In 1946, he won the first Polish Chess Championship after World War II. He also won it in 1951, 1952, 1953, 1954 and 1960. His last name is pronounced Shlee- (rhymes with plea), vah (rhymes with spa). 
    In the following game Sliwa defeated David Bronstein, who at the time was (along with Smyslov, Keres and Botvinnik) one of the best players in the world. At the time of the game Sliwa was way, way down the list...not even in the top 150 according to Chessmetrics. 
    The game came to be known as The Immortal Losing Game. It likely got that moniker because of the rating difference and not because Bronstein even came close to getting a better position let alone winning. Instead, Bronstein found himself in a hopeless position, but managed to lay some elementary traps, but the alert Sliwas avoided them and emerged victorious.

The Aggressive f-Pawn Advance

    
Ludek Pachman (1924-2003) won the 1957 Czechoslovak Championship that was held in Prague. Pachman was a dominant figure in Czechoslovak chess during this era and was known for his strong international performance, including victory in the 1957 Dublin Zonal tournament. 
    Few people realize how strong Pachman was during the late 1950s. (n their December 1959 rating list Chess metrics rates him at 2695 placing him at #15 in the world. That put him in a group with names like David Bronstein, Bobby Fischer, Lazslo Szabo, Miguel Najdorf and Samuel Reshevsky. Mikhail Botvinnik (2797) and Pail Keres (2772) lead the list. 
    Remember these ratings do not compare to those of today! Ratings measure statistical performance against opponents, not absolute strength. A good example of this point was made in the 1970s by  Claude F. Bloodgoo III (1937-2001), a petty criminal who was serving a life sentence in the Virginia State Penitentiary for murdering his mother. 
    Bloodgood was of about Expert (200-2199) strength, but he pumped up his rating to over 2700 when he manipulated the rating system by creating a rated pool of fellow prisoners and submitted fake tournaments. 
    In the process of winning the ‘57 Czech Championship Pachman played the following instructive game that illustrates the motif of advancing the f-Pawn which can be either a high-risk or a high-reward tactical and positional idea that is used to break open the center or launch a K-side attack. 
     In the King's Indian Defense the advance of the f-Pawn is a common aggressive strategy that initiates a Pawn storm against the opponent's castled King.

Unlawful Upsetting of the Balance

    
According to Chess metrics calculation, on the September 1950 rating list Soviet GM Alexander Kotov (1913-1981) was tanked #3 in the world behind David Bronstein and Vassily Smyslov. 
    His best result came at the 1952 Saltsjibaden Interzonal where he finished an undefeated first hree clear points ahead of Tigran Petrosian and Mark Taimanov. In the Candidates Tournament in Zurich in 1953 he tied for 8th place out of 15. 
    Kotov wrote several books, but he is probably most famous for Think Like a Grand master (1971) and Play Like a Grandmaster (1973). Both are heavy reading. In Think Like a Grandmaster he teaches amateurs how Grandmasters think. His main focus is on the what he calls the tree of analysis, candidate moves and the decision-making process. In Play Like a Grandmaster, Kotov gives a practical guide that focuses on things like positional judgment, planning and calculation. 
 
 
    In describing the following game Kotov observed how sometimes in the opening one of the players “flagrant1y violates the genera1 princip1es” of the opening and “his moves are not ίn accordance with the requirements οf the position, presenting themse1ves either as a loss of time or cutting across the genera1 harmonious setup of the pieces. 
    Kotov wrote that when that happens, the opponent “have the right and are obliged to punish the opponent for such a disregard of general chess princip1es.” He added that such punishment is often carried out “quickly with maximum energy from the attacking pieces.” 
    That’s what happened to Wade in this game. His first few opening moves do not seem as bad as Kotov claimed or were they? Stockfish doesn’t show black’s position to be losing after 5...f6, but only that white is better by a little less that a P. In practice though black’s survival chances are slim. Engines are tactical monsters, but are GMs better at evaluating long term strategic advantages? Also, take a look at the position after 7.c5. How many humans would play 7...g5 which appears to seriously weaken black’s K-side and leaves him with most of his Ps on dark squares? Yet, Stockfish fails to demonstrate any advantage for white.

Troianescu Crushes His Opponent

    
Today where I live the temperature is in the single digits and there is 6-8 inches of snow on the ground. Things were different on this date in 1951. It was mild with a high temperature of 62 degrees (F) and a low of 36. There was light precipitation that day measuring 0.08 of an inch. 
    Chess in 1951 was dominated by the Botvinnik-Bronstein World Championship match which ended in a 12-12 tie and so Botvinnik retained his title. Rumor has it that Bronstein was ordered not to win. 
    It was also the year 7-year-old Bobby Fischer lost a simultaneous game to US Senior Master and US Speed Champion Max Pavey. The loss resulted in Fischer subsequently being invited to join the Brooklyn Chess Club and you know the rest of the story. By the way, on January 17, 2008, Bobby Fischer died at the age of 64 in Reykjavik, Iceland. 
    1951 saw the development of the first operational computer chess program by Dr. Dietrich Prinz in England. It ran on a computer at the University of Manchester. The program was not capable of playing a full game. Instead, it was designed to find the best move to win within two turns. 
    In Romania in 1951, the communist regime intensified political repression which included the torture of political prisoners, the launching of forced agricultural collectivization and rapid industrialization. 
 
 
    That was the world of Octav Troianescu (1916-1980), an International Master (title awarded the previous year). From the mid-1940s to the end of the 1970s he was one of the strongest Romanian players winning the Romanian Championship in 1946, 1954, 1956, 1957 and 1968. His highest rating was 2320 in 1971. Here is one of his games to enjoy.

Averbakh’s 1950 Brilliancy

 
    
When Soviet Grand master Yuri Averbakhpassed away in Moscow on May 7, 2022 at the age of 100 the chess world lost a rare, if underappreciated gem. Chess metrics estimates his highest ever rating to have been 2715 in 1952, placing him at #8 in the world (Smyslov was #1 at 2783). Douglas Griffin has written an excellent biography on Averbakh HERE
    The year 1950 saw a lot of brilliant games played. For example, the inaugural Candidates Tournament that was played in Budapest was made up up of a group (Bronstein, Boleslavsjy, Smyslov, Keres, Najdorf, Kotov, Stahlberg, Szabo, Flohr and Lilientahl) of the best players in the world, so you know they played some brilliant games. 
    Today’s game was played in the 1950 USSR Championship and you just know that group must also have played some great games and Yuri Averbakh's victory over Alexey Suetin was one of them. The game is notable for its brilliant concluding sequence where Averbakh’s pieces overwhelm his opponent. 
Averbakh was born in Kaluga, a city in western Russia. He was awarded the GM title in 1952. and played in the Zurich Candidates (1953). Averbakh won the USSR Championship in 1954 and tied for first first in the 1956 championship, but lost in the playoff. He published more than 100 endgame studies and was known as an opening and endgame theorist. In the late 1950s and early 1960s, he co-edited a five-volume anthology on the endgame, Shakhmatnye okonchaniya. In addition to authoring numerous chess books he also edited a couple of major Soviet chess magazines.
 

    Alexey Suetin (1926-2001, 74 years old) was awarded the GM the in 1965 and became World Senior Champion in 1996. His best tournament results were in the mid-1960's. He was also an author of note.

Role Reversal

    
The game in the previous post was one in which Miguel Najdorf won using his then new variation and Fred Reinfeld was highly critical of white’s 10.f5 saying that the Pawns on light squares meant that white’s Bishop was bad as a result. Also, the move releases pressure on the center and so left open the possibility of a Pawn break with ...d5 by black. 
     Is the move really that bad? Just to be fair I wanted to look at a game that white won and found several in my database. I wanted the players to be GMs and found a couple games in which former World Champion Anatoly Karpov played 10.f5 and won. I also found the following game in which Najdoff was playing black again. 
    A casual look at some of the games seem to show some commonality. Unless black played badly, white’s wins were lengthy and they were not obtained by direct K-side attacks. Bronstein’s notes to this instructive game explain the real purpose of 10.f5

A Kotov Brilliancy

Alexander Kotov
    The 1952 chess year started with Svetozar Gligoric winning Hastings 1951/52. Mikhail Botvinnik and Mark Taimanov tied for the USSR championship and Botvinnik won the play-off match. Twenty-year old Larry Evans crushed veteran Herman Steiner 10-4 in a US Championship match. Evans also won the US Open that year. 
     In other chess news, Hungarian master Geza Fuster (1910-1990) defected and sought asylum and eventually immigrated to Canada. Samuel Reshevsky defeated Miguel Najdorf 11-7 in a match that was billed as being for the Championship of the Free World. Svetozar Gligoric took first on tiebreak over Oscar Pomar in the Hollywood International. 
    The USSR team (Keres, Smyslov, Bronstein, Geller, Boleslavsky, and Kotov) won the Helsinki Olympiad. The US team (Reshevskym Evans, R. Byrne, Bisguier. Koltanowski and Berliner) finished fifth. 
    The following players were lost that year: Robert F, Combe (born 1912), former British champion, died in Aberdeen, Scotland. French problem composer Henri Rinck (born1870) died in Barcelona. Talented Czecg IM Jan Foltys died at the age of 43. Efim Bogoljubov died at the age of 63 in Triberg, Germany. British player William Napier (born in 1881) died in Washington DC at the age of 71. British chess author Philip W. Sergeant (born 1872) died in England at the age of 80. 
    In the following game played in the 1952 Stockholm Interzonal. Alexander Kotov’s victory over Gedeon Barcza, an eight time Hungarian champion, is remembered for his attacking play, particularly his Knight sacrifice on f5. His win was the culmination of his strong opening play against Barcza’s less than optimal handling of that phase of the game.
 

    This event was the highlight of Kotov’s career; he finished first with a dominant score of 16.5-3.5. He finished a full three points ahead of Taimanov and Petrosian. In the 1953 Candidates Tournament in Zurich, he was dar less successful posting a 14-14 score and tying with Taimanov for 8th place (out of 15).

A Chess Hors d'oeuvre


    In 1947, the major chess activity in California included ia match between Reuben Fine and Herman Steiner who played six game at the homes of sponsors and the Hollywood Chess Group headquarters. Fine won 5-1.George Koltanowski, a chess journalist, moved to Santa Rosa and established the California Chess News magazine. That was the major news coming out of California that year. Today’s game, just an hors d'oeuvre, was played in the finals of the Capitol City Chess Club in Sacramento.

Same Story, Different Setting

    
The international tournament that was held in Venice in 1948 ended up in forgotten event category. Chess Life of the day didn’t mention it and Chess Review had a blurb on it, but had some unflattering remarks about Najdorf and Euwe. 
    The magazine noted that after his tie for sixth place at the tough Saltsjobaden Interzonal Najdorf must have found winning the Venice tournament a breeze, adding that he celebrated the absence of Soviet opposition and that’s what resulted in a “handsome lead” over the opposition. The 20 player Saltsjobaden tournament was won by David Bronstein, who along with seven other players advanced to the 1950 Candidates Tournament. 
     The short article added that former World Champion Max Euwe was unable to shake off a poor start. His two losses (against Canal and Castaldi) combined with difficulty in defeating the tailenders resulted in him being “just another chessplayer.” 
    Venice consisted of twelve players, six Italians, two South Americans and four from Europe, including former World Champion Euwe. Not only did Venice have competition form the goings on at Saltsjobaden, but it was just one of many tournaments that year that fell under the shadow of the 1948 World Championship tournament held to determine the new Champion following the death of Alekhine in 1946. This tournament (won by Botvinnik ahead of Smyslov, Jeresm Reshevsky and Euwe) marked a significant shift in the international chess scene as the FIDE took control of the world championship title and the cycle of tournaments leading up to it. 
    The winner of this game, Giuseppe Primavera (1917-1998) was Italian Chess Champion in1948, 1953, 1954 and1970. He was one of the founders of the organization Association of Chess Masters of Italy and in 1973-1974, he published the chess magazine Tutto Schacchi. IM Henri Grob (1904-1974) was Swiss champion in 1939 and 1951 who is best known for popularizing the Grob Attack (1.g4). 
 

 
    Their brief encounter at Venice has the same plot as the game between Koenig and Weinberger in the previous post. In this game Primavera erred in the opening and Castaldi got an overwhelming attack, b A game that I liked (Fritz 17)
