Long Forgotten, Little Remembered

     Speaking of chess players, their games and the tournaments they played in, the vast majority of them fall into the category of being long forgotten and little remembered. The following game, the players, the tournament and even the book I found it in is in that category. 
     One of the books I like to dip into occasionally is the 1913 edition Memorable Chess Games, Brilliants and miniatures with Notes, Quires and Answers by the British player and author William Moffatt. 
     The reason I like the book is because, as the author pointed out in the forward, is that, "In some of the games in this collection there are moves which are weak and lead to disaster. Such games in the opinion of some players are not worth attention. Nevertheless, if the reader will himself take the trouble to discover these faults and to indicate better lines of play, he will benefit considerably. He will strengthen his play by learning to avoid danger and to take advantage of error. Hence, questions on interesting points are set down, to which the student is expected to provide answers and to compare with those given at the end of the work." I think he has a point. 
      Not all of the games were played by unknowns in forgotten tournaments; it's just that some of the players were not members of the chess world's aristocratic class and the games were not unblemished. I
     The following game won the brilliancy prize at "the Scarborough meeting of the British Chess Federation," but no date was given. It was most likely played in the First Amateur B event in Scarborough 1909 which was part of the British Championship. 

     Georg Shories (1874-1934) was born in Berlin which is also where he died. He took up chess seriously in 1895. He lived in England for a number of years and his first notable success in English chess was winning first prize in the 1903 Open Tournament at the Kent County Congress at Canterbury. 
     In 1905 he competed at the Barmen Congress of the German Chess Association, and won first prize in the B tournament. In 1908 he won first prize at Ostend in the Amateur event and, also, first prize in an amateur section of the tournament of the British Chess Federation. In 1909, he tied with Wahltuch in the Blackpool tournament for the championship of the North of England. 
     During the First World War, he suffered internment, and then returned home to Germany. His last tournament was at the Bad Pyrmont (German Championship of 1933) in which he was the oldest participating master. 
      Nothing is known about Joshua W. Dixon except that he lived in Hanley. Located in central England, it was one of six towns that in 1910 amalgamated to form the City of Stoke-on-Trent.

Dilworth Variation, it's not for the faint of heart

     Unless they're a peddler of opening books, most titled players advise amateurs not to spend a lot of time studying openings because time is better spent on tactics, middlegames, endgames, strategic concepts etc., etc. 
     Take a look at game below the master level and you'll see they don't go much beyond 6-8 book moves. And, I remember the time my young opponent blitzed out 20 or so opening moves against my Sicilian. Finally, when he sank into deep thought I knew he was at the end of his book knowledge. A few moves later he blundered and lost. In the post mortem I got a lecture about my move (the one that made him stop and think) being a bad one. The reason...it wasn't what Fischer played. My question was, if the move was so bad why didn't he refute it? I got a blank stare. 
     For us chess putterers, a general overview of openings should be sufficient. And, as for making your opponent think on his own and playing tactical tricks on him because chess is supposed to be 99% tactics...well, we are non-masters because we don't think very well on our own and our tactical vision is third string...unless, perhaps, we are doing tactical exercises and are told there's a mate in three or some such. There's nobody to tell us that during a game. That's why our chess is so dreadful. 
     The Dilworth Variation of the Ruy Lopez is one of the few opening variations named after an amateur player. Vernon Dilworth (September 16, 1916 - October 9, 2004, 88 years old) was a railway clerk who experimented with the line in the years of 1939-1941 in correspondence games, and then published some of his analysis in Chess magazine. 
     His variation got recognition when, even though it was unsuccessful, Botvinnik played the variation against Vasily Smyslov in the 1943-44 Moscow Championship. In more modern times, although today it's not often seen, players like Larsen, Ivanchuk, Short, Leko and Yusupov have played it. 
     The Dilworth is one of the most interesting variations of the Ruy Lopez. Black gives up a B and a N for R and P, or maybe two, in the hopes of launching an attack on white's K. If White is successful in fending off the attack the result is usually a very complicated ending which theory considers to be about equal. 
     Just for fun I let Stockfish 15 work on the Dilworth (the position after 11...Nxf2) for 45 minutes and its evaluation was slightly less than half a P in white's favor, i.e. equal. It should be noted that being equal does not mean drawn. 
     The following game is an early example of Dilworth's experimentation and it shows the complexities of his variation. It's certainly not for the faint of heart.

Beauty is in the Eye of the Beholder

     Margaret Wolfe Hungerford is credited with coining the phrase in her novel Molly Bawn, published in 1878. The saying means that different people have different opinions as to what should be deemed attractive. It means that beauty is subjective, but whether or not that is true has been debated since ancient Greece.
     Shakespeare wrote of beauty in Love’s Labor Lost, saying, “Beauty is bought by judgment of the eye…” Benjamin Franklin wrote in Poor Richard’s Almanack, “Beauty, like supreme dominion/Is but supported by opinion.” 
     According to one article I read you should never say that because "it’s a phrase with the power to silence. Once it’s been uttered, trying to keep up a dialogue about the merits or drawbacks of certain visual things can come across as shrill, anti-social or just plain rude." 
     Aron Nimzovich struggled with the beauty problem in his day. He wrote about it in one of the seldom looked at books in my library, Chess Praxis. The book is his companion to My System and is what he described as, "A textbook of practical chess, illustrated with 109 games from my struggles." In other words, it's a collection of his games. 
     The late chess book publisher Bob Long didn't think much of the book. He thought it has discouraged more chess players than any other book. But, if you read the reviews, some people loved it. Beauty is in the eye of the beholder, as the saying goes. 
     Topics covered include centralization, restriction and blockading, over-protection and prophylaxis, isolated Pawns, hanging Pawns and the two Bishops One of the chapters that caught my attention was "A victory parade of bizarre and ugly moves" ...those two games have to be worth looking at! 
     Nimzovich wrote that it was words like "bizarre and ugly that masters of the "pseudo-classical school" used to describe his moves. But then he asked, since his ideas had "been totally victorious, can anybody claim to understand how such a natural, beautiful and profound line such as, for example, the Hanham Variation (of Philidor's Defense) was ever considered ugly?!" He then explained that "...the formalistic pseudo-classical way of looking at things is dead and you can't flog a dead horse." 
     He also addresses the Advance Variation of the French Defense (1.e4 e6 2.d4 d5 3.e5). Once upon a time the move was considered unmotivated and ugly because it didn't attack anything, but he insisted for 20 long years that it was neither a mistake nor ugly, but a good and sensible move. 
     His claim was that often the judgment of the pseudo-classical school often saw neither the dynamism nor the intrinsic beauty in many of his recommended moves. He summed things up by saying, "...in chess aesthetics must be firmly anchored in concrete thought. If you only judge by external appearances, you can easily consider some moves ugly which are not so. Beauty in chess, in the final judgment, exists only in thought." 
     One game he examined under this heading is Nimzovich vs. Gilg from Kecskemet 1927. You can play over that games with notes by Raymond Keene HERE. The other was his game against Alekhine played in the famous New York 1924 event; Nimzovich called it, "A battle of giants(!)" Take a gander...

Firstly, the draw (after 24...Qc2) would not be certain and secondly it has not yet been proved that white did not have a stronger line somewhere along the way (for example on move 22), and thirdly, there are unfortunately many positions in which a clearly demonstrable advantage is not enough for a win (victory by attrition should be included!). - Nimzovich.

Petrosian Played Like Tal

     The 1968 Moscow City Championship was a very strong tournament which included World Champion Tigran Petrosioan. He was, as is well known, a solid positional player and this was his second tournament in a row (the other was an international event in Bamberg, Germany) in which he did not lose a single game.
     He was sometimes criticized for his strictly positional play, but that was simply a matter of preference; you do not get to be World Champion with out being very good at all phases of the game, including tactics. 
     Petrosian's opponent, Yakov Estrin (1923-1987) was an IM, theoretician, writer and World Correspondence Champion who held the Correspondence Grandmaster title. Estrin was an authority on the Two Knights Defense. His game with Hans Berliner in which Berliner played the Two Knights and won is one of the most famous and important games in correspondence chess.
 

     In OTB play, Chessmetrics estimates Estrin's highest ever rating to have been 2595 in 1974 and that placed him at number 90 in the world. At the time this game was played Chessmetrics estimates his rating to have been 2456 which was no where close to even the top 100. 
     As an opening theoretician, Estrin's poor play in the opening is quite surprising and Petrosian took advantage of it and crushed him.

An Impressive Win By Santasiere

     In the last post it was described how President Roosevelt moved Thanksgiving from the last week in November to the 4th week in November. In this post we're still in 1939. 
     That was the year that the New York Times predicted television would fail because the average American family would not have enough time to sit around watching it. Today, on average, 79% of people over the age of 15 spend about 3 hours a day watching television. For those over 65 years old, the average is about an hour more. In 1939, a lot of the over 65 crowd would not have been available to watch television because life expectancy for men was 62.1 years and 65.4 years for women. 
     In 1939 General Motors introduced the first mass-produced, fully automatic transmission as an option for the 1940 model year Oldsmobile. And, Ernest Vincent wrote the book Gadsby which has over 50,000 words in it without containing the letter e, the most common letter in English. The plot revolves around a dying fictional which is revitalized as a result of the efforts of John Gadsby and a youth organizer. 
     In other happenings, Batman made his first appearance in Detective Comics, Amelia Earhart was officially declared dead after her 1937 disappearance. The first Thin Mint cookies were sold by the Girl Scouts and the first Little League Baseball game was played in Williamsport, Pennsylvania. Also in baseball, the Hall of Fame was dedicated in Cooperstown, New York. 
     One of the popular songs of the day was God Bless America sung by Kate Smith (May 1, 1907 – June 17, 1986). She was known as The First Lady of Radio and besides the song God Bless America, When The Moon Comes Over The Mountain. She became known as The Songbird of the South because of her tremendous popularity during World War II. 
     I remember Kate Smith from my youth when she appeared on TV shows like The Ed Sullivan Show where she sand her iconic songs. I thought they were awful. 
     For over a year following her death, her remains were stored in a vault at St. Agnes Cemetery in Lake Placid, New York where she regularly attended Sunday Mass and could be heard singing the hymns, while church officials and Smith's executors engaged in a dispute over her request to be buried in a mausoleum on the cemetery's grounds. Her private burial service wasn't held until November 14, 1987. If you can tolerate it, you can listen to her sing HERE.
     The following game was played in the 40th ACF Congress in New York City which ran July 18-29, 1939. This tournament was an important one...at the closing dinner an announcement was made concerning the merger between the American Chess Federation and National Chess Federation. The new organization would be known as the United States Chess Federation.
 
Finals section

     This tournament had a new rule, too. Players had to make 40 moves with two hours and special time clocks were used. 
     Anthony Santasiere's victory in the following game is impressive. His opponent, Boris Blumin (1908-1998), was born in St. Petersburg, Russia, later settled in Canada and in the late 30s was Canadian Champion in two successive years. Later in life, he moved to New Jersey where he won the Hamilton Chess Club Championship at the age of 78.

Eliskases vs. Bogoljubow Match

     Even though World War II had broken out on September 1, 1939, the big brouhaha in the United States was when Thanksgiving should be held. 
     On November 23, 1939, President Franklin Roosevelt carved the turkey at the Thanksgiving Dinner on his estate in Warm Springs, Georgia and wished all Americans a happy Thanksgiving. All Americans weren't happy though. 
     Many were not observing Thanksgiving on that day...they were waiting to celebrate the holiday the following Thursday because in many states November 30th was the official Thanksgiving Day. 
     In those days, legally, Thanksgiving was not a fixed holiday; it was up to the President to announce what date it would fall on. By tradition, since 1863, it was always the last Thursday in November because that's when President Lincoln declared it a national holiday. 
     Statistics showed that most people began their Christmas shopping after Thanksgiving and since 1939 had five Thursdays, merchants feared they would lose money because there were only 24 shopping days until Christmas...so they asked Roosevelt to make Thanksgiving a week earlier. Thus, Thanksgiving in 1939 would be held, the President proclaimed, on the 23rd and not the 30th. 
     Changing the date proved to be a contentious move. Thousands of letters poured into the White House opposing the change. Some retailers were pleased to get the extra week of Christmas shopping which would increase profits, but smaller businesses grumbled that they would lose business to larger stores. How is not clear. 
     Calendar makers were enraged because they had already printed calendars for 1940. Most schools had already scheduled vacations and annual Thanksgiving Day football games and the change disrupted everything. 
     And, many were angry because they claimed Roosevelt was trying to alter not only a long-standing tradition, but, also, American values just to help businesses make more money. Some states defied Roosevelt and declared November 30th as Thanksgiving anyway. 
     It wasn't until Congress to passed a law on December 26, 1941, declaring Thanksgiving to be on the fourth Thursday of November every year that the mess was straightened out. 
     In the rest of the world more important issues were at stake because they were at war. In the chess world, the Olympiad in Buenos Aires had been disrupted by the outbreak of the war which happened just after the completion of the preliminaries. 
     The English team returned home immediately and Stuart Milner-Barry, Harry Golombek and C.H.O'D. Alexander went to work at the top-secret code-breaking station at Bletchley Park. 
     Remarkably, the final went ahead, but the French, Polish and Palestinian teams refused to play against Germany. Organizers decided that unplayed matches would be scored as 2-2 draws. Germany won ahead of Poland and Estonia. 
     Many European players remained in Argentina after the Olympiad and eventually settled in South America, rather than return to war torn Europe. 
     After the Nazis annexed Austria in 1938, Austrian players were incorporated into the Greater German Chess Federation. After the annexation the only two players of equal stature were the aging Efim Bogoljubow who was almost almost fifty years old and twenty-five year old Erich Eliskases. 
     On the Chessmetrics January 1939 rating list Eliskases is ranked 9th and Bogoljubow 11th. They played a 20-game match between the 4th of January and the 12th of February 1939 that took place in eleven towns and cities in Germany.
     It was a clash of styles. Bogoljubow, while a player of strong positional skills, was primarily known as a strong tactician. Eliskases was a predominantly positional player and technically proficient in the ending. 
     Halfway through the match Eliskases had lost only the first game and had a huge 3 game lead. But, in the second half Bogoljubow fought back and won two games, but also lost two.

Then in the 1950s players in the Soviet Union, especially Mikhail Tal, began using it.

A Short, Sharp Win by Kimball Nedved

     On Tuesday, January 14, 2020, Kimball Nedved passed away at the age of 91. At the time he was living in Cumberland, Maryland.
     He graduated from Illinois Institute of Technology with a degree in psychology, a B.S. in 1952 and an M.S. in 1953. 
     In 1953, he was drafted into the Army and at Fort Benning, Georgia he made the rifle team which was the precursor to the elite Marksmanship Unit. Today this unit is made up of fewer than 100 soldiers who are at the top of the marksmanship game. They are the best of the best, not just in the military, but also in the competitive shooting world. These expert marksmen support readiness and recruiting, and train and compete year-round, including for the Olympics. 
     Also, while at Fort Benning Nedved did psychological testing of thousands of paratroopers training at the Airborne School's "Free Towers" which are 250 foot high towers from which students are dropped as part of their training. 
     After his service, Nedved worked in advertising for one of the world's largest ad agencies. His market research lead to employment with Johnson Wax where he helped develop Glade air freshener. Next, he worked for Campbell Soup and then Heinz Ketchup. 
     Eventually, he and a partner founded a company that provided market research for 30 years to most supermarket chains and large retailers in North America. 
     Besides chess, Nedved also loved history, especially studying the strategies used in the US Civil War and he greatly enjoyed visiting historical sites and national parks. 
     Nedved won the 1951 Illinois State Championship and the 1969 US Amateur Championship. His team won the 1986 US Amateur Team Championship. In 1987, his rating was 2321 and in 1988, when Carnegie-Mellon University was developing Deep Thought, they tested it by having Nedved play against it. 
     When Nedved won the 1969 US Amateur Championship held in Philadelphia, he was rated a USCF Expert (2000-2199) and living in New Jersey. He topped an entry 1ist of over 250, including the championship and reserve sections, with a perfect 6-0 score. His win from George Miller, who tied at 5-1 with four others for third place, is the featured game today...and it's a beauty.

A Complicated Charousek Game

     Rudolf (Rezso) Charousek (September 19, 1873 - April 18, 1900) was a Czech born Hungarian player who was one of the top ten players in the world during the 1890s. On the March 1900 rating list Chessmetrics estimated his rating to be 2734 placing him #6 in the world behind Lasker, Tarrasch, Pillsbury, Maroczy and Janowsky. 
     Charousek had a short career, dying at the age of 26 from tuberculosis. Reuben Fine wrote of him "Playing over his early games...you cannot help feeling a grievous, oppressive sense of loss, of promise unfulfilled". 
     Born near Prague, at the age of five weeks his family moved to Debrecen, Hungary, where he became a naturalized Hungarian citizen. He learned to play chess at the age of 16 while studying law and he is said to have copied out the voluminous Handbuch des Schachspiels by hand, unable to afford his own copy.
     Despite the lack of competition during that time he soon became a strong player and also qualified as a lawyer. In 1893, he entered a correspondence tournament in which he shared first place with another up and coming (and later great) Hungarian player, Geza Maroczy. He joined the Budapest chess club where he frequently played Maroczy and other prominent players of the day. 
     An almost unknown player, his style was between two schools of chess. Way back in 1946, Reinfeld and Horowitz published Chess Strategy and Tactics and in it they made the observation that like the masters of the Morphy-Anderssen period, he often played the King's Gambit. But, unlike them, he rarely won brilliantly with it. Instead, in gambit openings he introduced the concept of positional motifs and playing for the ending. They reached the conclusion that based on a careful examination of his games, he represented a contrast to the popular conception of him as a belated Romanticist. 
     The following game is an exception. Lamentably, the game was superficially annotated as I discovered when going over it with Stockfish and Komodo. The game turned out to be much more complicated than their notes indicated. I don't want to disparage Reinfeld and Horowitz because it's a complicated game and 1) they didn't have engines and 2) if one wanted to dig deeper into the game, it's possible that my notes might not bring to light all of the bountiful possibilities! 
     It should be noted that this was a casual game played during the 11th DSB Kongress held in Cologne in 1898. In that tournament, won by Amos Burn, Charousek tied for second with Chigorin and Cohn. Their individual game was drawn.

Penrose Pummels Barden

     Finally! After three days of a cold, dripping rain (with a few snow flurries in some locations), a 300 mile wide front stretching 1,300 miles from Ontario, Canada to southern Ohio, is finally clearing out and a warm up (maybe near 70 degrees!) is on the way. 
     The gloomy weather meant the last couple of days allowed for some time playing blitz on line, but my play was as wretched as the weather. Ergo, I spent some time looking through Ludek Pachman's old book, Modern Chess Tactics, which was first published in English in 1970. It was a companion to Modern Chess Strategy which I also have. Pachman, I should mention, was an excellent writer.
     One game that I came across was the following fantastic game by Jonathan Penrose (October 7, 1933 - November 30, 2021, 88 years old). He won the British championship a record 10 times, yet he always remained an amateur whose chess career was fitted into vacations at Middlesex University, where he lectured in psychology. 
     In 1960, at the Leipzig Olympiad Penrose defeated Mikhail Tal and Max Euwe then caught Bobby Fischer’s King in the middle of the board, forcing him to settle for an endgame a Pawn down. Short of time, Penrose offered a draw. Fischer replied “Sure!” then demonstrated a forced win for Penrose. 
     By the age of 17, Penrose was acknowledged as a top prospect. At Southsea in 1950, defeated both Efim Bogoljubov and Savielly Tartakower. Playing in Hastings for the first time in 1950/51, he beat the French champion Nicolas Rossolimo and in 1952/1953, he shared the first place at Hastings with Harry Golombek, Antonio Medina and Daniel Yanofsky. 
     Penrose earned the IM title in 1961 and was the leading British player for several years in the 1960s and early 1970s. He was widely considered to be of GM strength, but did not achieve the title during his active playing career. He also held the GM title in correspondence chess. Chessmetrics assigns him a high rating of 2610 on the February 1969 rating list placing him at number 57 in world. 
     One of the primary goals, starting right in the opening, is to invest the pieces with a greater degree of effectiveness. Even moves like 1.e4 and 1.d4 open lines for the pieces while a move like 1.Nf3 brings the N into play. Later, in the middlegame this goal can include such things as the opening of a diagonal for a B, transferring a N to an outpost, the opening of a file for a R, etc. 
     In the following game played at Hastings 1957/58, Penrose's tactical shot 15.Bf4 was played with the realization that at the end of the sequence at move 19 his Queen would be much stronger than the combined forces of his opponent's Rook and two Bishops. So said Pachman. 
     Unfortunately (?), today we live in an age where laptops coupled with chess engines enable any armchair Grandmaster to poke holes in the play of guy's like Nezhmedinov, Tal, Bronstein or any other great player you can name because engines find the defects no matter how small or deeply hidden. 
     That's what happened when analyzing this game...Penrose's 15.Bf4 was found wanting by the engines. It doesn't matter because we humans can still delight in such a move. The concept was brilliant and in practical play it was crowned with success. 
     His opponent, Leonard Barden, is an English master, writer, journalist, organizer and promoter. His weekly Guardian chess column began in September 1955 and continued for sixty-one years. Barden was born on August 20, 1929, and as far as I know he is still among the living and that would make him 93 years old. Chessmetrics estimates his highest rating to have been 2497 on the January 1958 rating list and his best tournament result to have been in this Hastings event.

The (Not So Great) Vazquez vs. Sterling Matches

     Manuel Marquez Sterling y Loret de Mola (1872-1934) was born in Lima, Peru to Cuban parents and died in Washington, DC. He was a Cuban diplomat and interim President of Cuba for 6 hours on January 18, 1934. At the age of 16 he began a career in journalism writing for publications founded by his father.
     Suffering from asthma, part of his adolescence was spent in Mexico because his father believed the climate would help. While there he met Jose Marti, a Cuban poet, essayist, journalist, translator, professor, and publisher, who is considered a Cuban national hero and an important figure in Latin American literature. 
     Sterling was credited with saving the life of Mexican President Francisco I. Madero, when the latter was hiding from the authorities at the beginning of the Mexican Revolution. Sterling served in the revolution then in 1901 went to Washington as member of the Cuban mission where he unsuccessfully protested against the Platt Amendment, legislation which outlined US policy for its meddling in Cuban affairs. 
     After a journalistic career, he served in diplomatic service for many years as ambassador to Mexico and the United States. 
     Sterling tied for last place in the Paris 1900 tournament (won by Emanuel Lasker) that was held during the world exhibition. As an author, Sterling wrote about 15 books on diverse topics such as politics, history and chess. 
     He played, and lost, two matches against Andres Clemente Vazquez (1844 - 1901), a Cuban-Mexican problem composer who was an attorney by profession. In 1869, he emigrated to Mexico, becoming a naturalized Mexican citizen the next year. 
     In Mexico he collaborated in different periodicals and was a member of various organizations publishing his works such as Mexican Orators, Political Rights and Duties, Minorities Representation in Popular Elections. 
     Vazquez became a distinguished Consul of Mexico in Havana, a position which he held until his death. In that position he was lauded for his outstanding performance in all his endeavors which included diplomacy, literature and in the courts. 
     He was also a first class player and wrote three chess books: Chess by Memory, Masterly Chess and Chess Game Analysis. He also served as the first chess club president of Mexico and composed many direct mates. 
     The first match was held in August of 1894 with Vasquez winning 4.5-0.5. It was supposed to be a ten game match, but Sterling resigned half way through not only because his bad play left him no hope of winning, but also because he wanted to take advantage of the few days of leave that he had been given to visit family in Port-au-Prince, Haiti. 
     They met again in January of 1900 in a match that was to go to the first to win five games, draws not counting. Vazquez was in the process of again trouncing his opponent with a +2 -0 =2 score when the match came to an abrupt end when Sterling was forced to resign the match when he had to leave for Washington. 
     The reason was that he had been appointed private secretary for Gonzalo de Quesada, a key architect (along with Jose Marti) of Cuba's Independence Movement. In that position Sterling was sent to the Universal Exposition of Paris as Cuba's representative. 
     The following was game 3 of their first match and it was a tactical humdinger...one worth playing over with a board and pieces if you want to sharpen your tactical vision and ability to see ahead.
