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.

Gligoric Surprises Pomar

    According to reports Torremolinos, a resort town in southern Spain known for its sandy beaches, is an excellent place to live if you crave year-round sunshine and vibrant coastal living, And they have an active chess club. 

    Today’s game is taken from the first in what was to be a long series of international tournaments and during the 1960s and 1970s, Torremolinos hosted a prestigious and long-running series of international tournaments in which players from all over participated. 

    In the first tournament Yugoslav GM Svetozar Gligoric (1923-2012) and former child prodigy, Spanish GM, Arturo Pornar (1931-2016) tied for first and this game was the reason.

 

 

    Few players appreciate how strong Pomar was, but Chess metrics estimates his highest ever rating to have been 2655 in March 1962 which ranked him #34 in the world. He was known for an intuitive, natural, and highly positional style of play, and he possessed excellent endgame technique, However, in this game his intuition let him down and he committed a game-losing blunder.

Using Let’s Check in Fritz

    Recently I did something I promised myself I would never do again...I entered a correspondence tournament. It has turned out to be more labor intensive than anticipated especially since two games are against ICCF Senior IMs. 

    The main reason for entering the tournament was my desire to test the new Swordfish engine, a Stockfish derivative that is supposed to be useful for analyzing sharp positions in which Stockfish could overlook some tactics. 

    The procedure was to use Swordfish and use the highly rated Reckless engine as a kibitzer. When the two engines agreed on a move it was played. If they did not agree, which was not often, then Stockfish broke the tie. The problem was that after 15 moves or so it began to feel like my positions were almost imperceptibly slipping into inferiority and so the decision was made to switch the main engine to Stock fish with Reckless as the kibitzer. 

    Although I have been using Fritz since the days of Ftitz 12 (2009) there is a feature I never bothered with until this tournament, the Let’s Check feature and I was curious to see if it was of any practical value, or was it just a bell, or maybe a whistle. 

    Let's Check has been around a long time and it is a cloud-based community analysis feature in ChessBase's software. It functions as a massive, continuously updated database of engine analysis. Reviewer Steve Lopez does an excellent job explaining it on THIS ancient YouTube video. 

    Take a look at the following position after 7...Nc5. 

 

  

    Below are the results of previously done analysis on this position.. Note that the top line is the output by Stockfish 18 that was running in my program. While all three engines agree that white should play 9.Qc6+, Stockfish’s analysis is much deeper and its evaluation is that the position is equal rather than white having a Pawn-plus advantage. 

 

 

    This feature could actually be quite helpful because it saves a great deal of analysis time. But…and this is a BIG but, how long was the time used for the analysis? If the analysis was done at only a few seconds per move, it’s really not that valuable. 

    My preference is to use infinite and to analyze using two of the four cores on my old laptop. In some critical positions I have left the engine running while I did something else. That is likely to be safer than trusting the analysis in Let’s Check.

Ex-GM Igos Kondytlev, Igors Rausis and Isa Kasimi

    The Latvian player Igors Rausis (1961-2024, 62 years old) was a rather unusual fellow. He was born Igors Kondylev, but changed his name after getting married to Olita Rause, a Latvian Woman Grand master. In 2003, there were allegations that he provided "occasional help" to her in her correspondence tournaments. In 2020 he changed his name again to Isa Kasimi after marrying his second wife Ajgul Kasimova. 

    An FIDE Trainer, he was the Latvian champion in 1995. He had been awarded the Grandmaster title in 1992, but it was revoked in 2019 after he was caught cheating.   

    In the early 2000s, when Rausis was in his 50s, his rating increased over 200 points to near 2700 which put him among the top players in the world. Was he using? You be the judge. 

    This was about the time Personal Digital Assistants (PDAs) with programs like Pocket Fritz running the engine Hiarcs were released for Windows Mobile pocket PCs. By 2008, these pocket PCs were already strong enough to win human tournaments. 

    By November 2008, Smartphones were popular and the open source engine Stockfish was released and it was soon available for mobile operating systems. Then in 2009, dedicated mobile apps, such as the Hiarcs was available.

`In July 2019, he was accused of cheating by using a mobile phone in the bathroom during a game. He admitted his guilt and in December 2019, FIDE revoked his GM title and banned him from OTB play. 

    Revoking his GM title seems unfair because he had been a GM before engines were at that level. He was diagnosed with cancer in 2003 and started taking medications and began chemotherapy in 2018. He died on March 28, 2024, at the age of 62.

The Amazing Donald MacMurray

    Donald MacMurray was born on November 14, 1914. His father was an alcoholic who drowned after falling off a pier. His mother was a cleaning lady who lived in the slums of Hell’s Kitchen in New York City. Despite the odds of such a background MacMurray possessed the highest IQ ever recorded up to the early 1930s, earned a BA degree from the University of Chicago in eight and a half months, and a law degree from Columbia University in one year. He was also a strong chess master.

    “Meckele” as he was generally known in New York chess circles was also an expert in languages and learned to speak Yiddish so he could frequent the Yiddish Theater. In 1935 to 1936 MacMurray completed his degrees and returned to New York and was married to his childhood girlfriend. 

    During the mid-1930s he played in several Manhattan chess club championships, always scoring well. Among his victims were Isaac Kashdan and Arnold Denker. Before leaving for Chicago to participate in the 1932 Western Chess Association tournament Denker and MacMurray played a short warm-up match that was drawn. Other well-known master who went down in defeat against MacMurray were Weaver Adams and I.A. Horowitz. 

    In the US Open Championship of 1937 he shared third place with George Treysman and then in 1938 he scored a remarkable 10.5 out of 11 in the Consolation Master’s section of the US Open after having narrowly missed qualifying for the finals. 

    In late summer in 1938, MacMurray was playing in the New York State Championship in Cazenovia when he began experiencing a worsening of nausea and stomach pains that were especially noticeable when he was laughing. At one point MacMurray was having dinner with Arnold Denker and the pain was so bad he had to leave the table and at Denker’s request. Another tournament participant, long time master Dr. Joseph Platz, examined MacMurray and discovered a cancer in his stomach that was the size of q grapefruit. Just three months later on December 2, 1938, MacMurray died at age 24. 

    In this game MacMurray easily defeats veteran master Harold Morton of Providence, Rhode Island. Morton was born on January 19, 1906 and won the championship of New England many times. He won the Massachusetts Championship in 1933, 1934, and 1935 and played in the 1936 US Championship. On February 17, 1940, he was killed in a car accident in Iowa when he hit a truck. His passenger, I.A. Horowitz, survived. The two were giving simultaneous exhibitions throughout the country.

A Trap That Backfired

    Games that are filled with traps, ambushes and swindles seem to be rare in these days of sophisticated chess, but while they may not always be correct games containing traps, ambushes and swindles are always fun to play over. 

    In the following game played in the 1920 championship of Scotland, black succeeds in trapping and winning his opponent's Queen, but the price was too high. The winner was William Gibson (1873-1932, 58 years old). Gibson won the Scottish Champion nine times between 1907 and 1931. He was a solicitor in Glasgow and joined the Glasgow CC in 1901. 

    Apart from his successes in Scottish chess, Gibson also played in several other tournaments and British Championships and was always a dangerous opponent. He was also an organizer and administrator, having held at one time or another almost every position in the Glasgow CC and the Scottish Chess Association, as well as being a member of the Council of the British Chess Federation. 

    His wife Margaret was the successful owner of Miss Buick's Tea Room in Glasgow. She would later open a second tea room and they were used by Glasgow chessplayers and clubs over the years. 

    Francis P. Wenman (1891-1972, 80 years old) was born in Croydon, England and was Scottish Champion in 1920 and passed away in Cardiff, Wales. He was associated with chess in Scotland after arriving from London in 1911 and joining the Glasgow Chess Club. 

    During his time there he played several matches against leading club players, including his opponent in this game whom hr defeated by a score of +7 -5 =5. Later, he would also be associated with the Edinburgh and Dundee Clubs, winning the championship of the latter in 1916. 

    Wenman authored or edited some 21 chess books, a number of them being on chess problems, but he was not highly regarded as an author. As a problem composer he was accused of plagiarism in his problem books. 

    I have one of his books, 175 Chess Brilliancies, which was published in 1947. In the introduction he wrote that the book had examples of most of the leading players of the world, but it was unlikely that the average player would have seen most of them. 

     Wenman wrote, “Many very brilliant games and endings from both ancient and modern records are presented to the reader, and it is hoped they will satisfy the desire of even the most ardent admirer of gambits and enterprising play.” One such game was his loss to Gibson; he won Gibson's Queen, but lost the game. 

 

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.

Max Ujtelky

    Maximilian Samuel Rudolf Ujtelky (1915-1979), aka Max Ujtelky, was a Czech IM (awarded in 1961) and theoretician of Hungarian origin. Ujtelky is pronounced OO-tell-key. He was a direct descendant of famous Hungarian composer Franz Liszt. 

    He shared 1st with Fichtl in the Czechoslovakia Championship in1960, but lost the playoff match for the title. He was a member of Czechoslovakia's Olympic team in 1954, 1960 and 1966. 

    His opponent, Stuart Wagman (1919-2007, 88 years old) was an FM and an American player who died in in Livorno, Italy where he had lived for the past half-century.  In the 1940s he had been a member of the Washington Chess Divan in Washington DC. 

    Wagman was inactive for many years but started to play again regularly after his retirement and earned the FM title when in his 60s and was a strong player even in his last years. At the age of 87 he scored 6-5 in the 2006 World Senior Championship. Chess metrics estimates his highest ever rating to have been 2444 in 1971.

Irina Perevertkina, Ladies Correspondence Champion

`Top level correspondence players claim that humans still have something to contribute to the output of their engines and it’s more than just a question of who has more computing power. They claim that opening preparation has a lot to do with it. They try to find a line that looks good on shallow computer analysis, but where deeper analysis yields a different opinion. Today's game seems to confirm that claim.

    Most correspondence games are drawn. For example, when Jon Edwards won the 2020-2022 World Championship she scored +2 0 =14. When Irina Perevertkina won the 2020-2023 Women’s World Correspondence Championship she scored ++2 -0 =8. 

    Irina Perevertkina is a prominent Russian correspondence player, holding the ICCF title of Lady Grand master which she was awarded in 1998. She was also awarded the International Master title in 2014. 

    She is best known as a two-time Women's World Correspondence Champion, having won the 9th edition (2011–2014) and successfully defending her title in the 10th edition (2014–2017). She was the last USSR Women’s Correspondence Champion 

    Beyond her correspondence achievements, Perevertkina has a background in over the board play. She competed in the final of the Moscow Championship in 1989 and participated in international open tournaments in 1990. 

    Perevertkina, nee Chepurnaya, was born in Moscow in 1967. She learned to play chess during preschool age from her father and grandfather. She then began training with professional coaches. 

    She graduated from Moscow State Technical University in 1991, earning a degree in engineering with a specialization in robotics. Although qualified as an engineer she did not pursue a professional career and worked in administrative roles in sports. 

    In 2010, Perevertkina obtained her Master's degree at the Russian State University of Physical Education, Sport, Youth and Tourism. This degree supported her long term involvement in coaching and organizational leadership within athletic institutions. 

 

Chess at 10 Seconds per Move

    In 1943, in the U.S. the war heavily influenced the daily news, but Hollywood dominated the entertainment world with morale-boosting films and swing music and jazz kept the home front dancing. 

    Frank Sinatra (the Voice) launched his solo career in 1943, complete with screaming teenage fans, known as bobby soxers. Many movie stars did not serve in World War II, but many did. For those who didn’t, the primary reasons were age, physical and mental health disqualifications, studio contracts, and government assignments that kept them in Hollywood. 

    As for the studio contracts, the major studios held strict contracts on actors and sometimes “heavily lobbied” draft boards to prevent them from bring drafted. For example, John Wayne was deferred due to his age, family dependency and a knee problem. The draft age was 18-45 and Wayne was only 36 years old in 1943 and his studio (Republic Pictures) fiercely fought to keep him in Hollywood. 

    Many stars “wanted” to serve but failed military physicals. Errol Flynn attempted to enlist but was rejected due to chronic health issues, including tuberculosis, recurring malaria, and an enlarged heart. Frank Sinatra was rejected in December 1943 because of a perforated eardrum and Army psychiatric files noted he displayed "emotional instability" and was considered unacceptable. He was manic-depressive, a condition characterized by extreme mood swings and emotional extremes. 

    The government itself discouraged some major celebrities from entering combat, arguing that they could best serve the country by remaining in Hollywood to make morale-boosting movies or by traveling on USO tours to entertain the troops. 

    Even so, many prominent actors saw active combat roles. Jimmy Stewart flew dozens of bombing missions over Nazi-occupied Europe, Henry Fonda served as a naval intelligence officer and Clark Gable served as a gunner on combat missions.

    In 1943, chess activity was limired by the war with international play largely suspended, but domestic and there was some tournaments in occupied territories. World Champion Alexander Alekhine lived primarily in Europe, playing in tournaments organized by the Axis powers in Prague and Salzburg and eventually made his way to Spain and Portugal. 

    The Soviet Union heavily prioritized chess as a cultural tool and held events in Sverdlovsk (won by Botvinnik), Kuibyshev (won by Konstantinopolsky) and the ongoing Moscow Championship. It was also the year Bobby Fischer was born. 

    The following game was played in the 1943, Y.S. Lightening Championship in New York City. Playing at the rate of ten seconds per move, 47 players competed. The winner, Reuben Fine, scored +20 -0 =2. The runner-up, U.S. Champion Samuel Reshevsky, lost only one game in the finals. The following game shows how quick the sight of the board world class players have. 

 

Crazy Defense, Fun Game

    Yesterday after a morning of yard work it was time to relax with a few online games. After facing a few opponents who played early Rook Pawn moves and premature attacks on f7, I met a very strong player. He was moving instantly and blundered a piece late in the opening. Then he wasted our time making me mate him in a Q+K vs. lone K ending. A few moves before mate I got a profanity laced note explaining he lost because I was playing so badly he got careless. 

    The one game that made the session worthwhile was the following one. Fritz’ Tactical Analysis lists the opening as the Scandinavian Defense, but the line was one I play quite often in these games and I like to call it the Danish Gambit Reversed. 

    The Danish Gambit is an aggressive, tactical opening for white that begins 1.e4 e5 2.d4 exd4 3.c3. White sacrifices a Pawn or two for rapid development, especially his Bishops, in the hopes of a strong early attach. 

    It was surprising to see that my opening book shows that after 3...dxc3 4.Bc4 cxb2 white wins 38% and black 37%. These stats are probably skewed because a lot of the games were likely played way back in the Romantic period when defensive technique was as refined as it is today. Also, I suspect a lot of the games were played by non-Masters. 

    My “Danish Gambit Reversed” is much less effective: White scores +6 -1 =4 in my database.. It is obviously unsound, but but it’s still fun to play, especially in Blitz games.Here is the "Blunder Category" chart from Fritz 19's analysis:

Miguel Najdorf, Tactician

    As far as I l know Miguel Najdorf (1910-1997) didn’t publish a book of his best games, but in 2005 Batsford published Najdorf: Life and Games by Beliavsky, Mikhalchischin and Lissowski. 

    The flamboyant Argentine Grandmaster has been described as a poet of the chessboard. His heyday was from the early 1940s to early 1950s and Chessmetrice estimates his highest ever rating to have been 2797 in 1948 (Botvinnik was first at 2829) and between July 1946 and June of 1949 he ranked #2 in the world on 33 different months! 

    How do you pick one of his best games? Chessgames.com lists 1,794 of them of which there are 861 wins to choose from. The following game was chosen at random and as Hans Kmoch wrote tactics “blossom in his games like buds in a fertile garden.”

    His opponent was Julio Bolbochan (1920-1996)/ He was born in Buenos Aires and was Argentine Champion in 1946 and 1948. He was awarded the IM and was awarded the an Honorary GM title in 1977.

Swordfish Engine

    Swordfish is a Stockfish derivative that is reported to have achieved good results in test suites.  Supposedly it can be useful for analyzing sharp positions where regular Stockfish can overlook some tactics.

    Swordfish is based on Stockfish, but is designed to be more aggressive and tactical. It balances calculation strength with a highly active, fighting style that often finds sharp, complex tactical lines in positions where Stockfish might settle for a less aggressive move. 

    Unlike Stockfish, which is optimized for absolute perfection, Swordfish leans heavily towards proactive attacks and sharp, forcing lines. This trait can make it a useful tool in some situations and it might be worth downloading which you can do HERE.

    I have not found any online rating for Swordfish, but on my laptop five game (4 minute plus 2 seconds per move) against Stockfish were drawn. Analysis was done with the Reckless engine and both engines scored a 100% accuracy rating. Therefore, I played another match against the weakest engine on my laptop, Lc0, and Swordfish scored 5-0. 

    In all five games Lc0 held its own until committing a catastrophic blunder that lost instantly. The following game was the most interesting because at the critical moment it took both Stockfish and Swordfish some time to realize that capturing the P on move 29 was a mistake. 

    As can be seen on the CCLR site, Stockfish is still the top rated engine, but only by a whisker and for most analysis purposes any of the top engines will do an adequate job.

Najdord Turns the Table

    In this game Najdorf got lucky. He nearly suffered the same fate as Capablanca at Carlsbad in 1929. The day Capa's wife joined him at the tournament he blundered against Saemisch, lost a piece and had to resign. 

    On the day this game was played Najdorf’s wife arrive at the tournament and he played the opening badly and found himself with a lost position. Fortunately for him though, Rellstab failed to press home his attack and instead opted to regain his sacrificed piece. Najdorf then found a stunning refutation that turned the table. 

    The game was played in the 1959 Bled tournament a major international event held in Bled, Yugoslavia. The tournament was a prestigious international event and helped launch the international careers of several emerging stars such as 16-year-old Borislav Ivkov who made his international debut. Also playing were veterans Saviely Tartakower and Milan Vidmar.

 

 

    Miguel Najdorf (1910-1997) 8s well known, but Ludwig Rellstab (1904-1983) is not. Born in Berlin, he was awarded the IM title at its inception in 1950 and the International Arbiter title in 1951. He was the German Champion in 1942.
