Mike Valvo

    
IM Michael Valvo (April 19, 1942 in Albany, New York – September 18, 2004 in Chanhassen, Minnesota) was, by 1962, one of the top blitz players in the United States. He won the 1963 U.S. Intercollegiate Championship. 
    Valvo was a graduate of Columbia University. He spent much of his life working with computers and is best known for his job as commentator for the Kasparov versus Deep Blue Matches in 1996 and 1997, but he accomplished many things in a chess career going back to the late 1950s. 
    Valvo learned the game from his father Frank, who was also a USCF Master. Michael made quick progress and in 1964 was a member of the U.S. team that competed in the 11th Student Olympiad in Cracow, Poland, in 1964 along with Bill Lombardy, Raymond Weinstein, Charles Kalme, Bernard Zuckerman and Mitchell Sweig. The Americans finished in fourth place behind the USSR, Czechoslovakia and Hungary. 
    He quit playing chess in 1969, but came back and earned a FIDE rating of 2530 in the late 1970s after an excellent performance in a NY Futurity. FIDE awarded him the IM title in 1980. By 1976, Valvo had essentially dropped out of tournament chess and his rating was no longer published in the USCF rating lists, until Bill Goichberg and Jose Cuchi invited him to a futurity tournament. Valvo did well and his rating rose to 2440. However, Professor Arpad Elo refused to award Valvo the rating because Elo had never heard of Valvo and suspected that the tournament had been rigged. 
    This matter was debated at the 1978 FIDE Congress in Buenos Aires and FIDE voted to give Valvo his 2440 rating. Valvo quickly proved that he really was a 2440 strength player and earned the International Master title. Valvo never played in the U.S. Chess Championship, but made his mark in computer chess, which became his primary focus. 
    At every World Computer Chess Championship from the early 1980s until his death, Valvo was the organizer, moderator, commentator or acted in some official capacity. He also played a two game play by email match against Deep Thought, winning both games. 
    A respected opening theoretician Valvo played 1.e4 for much of his career before adding the English to his repertoire. He was a life-long fan of the Dragon and a early pioneer (1963) of a Benko-gambit. He tested many of his lines in correspondence chess throughout his career. Valvo was a co-author of a book on the 1990 Kasparov-Karpov match and was the technical editor of Bobby Fischer Teaches Chess along with Raymond Weinstein. He did the game annotations for the 1966/67 US Championship bulletin. Valvo died of a heart attack. 
    Valvo’s opponent in the following game was Roberto Kaimo (1943-2016, 72 years old) from the Philippines. The gane was played in a large round-robin, the largest international event held in the US in 88 years. 
 
 
    GM Anatoly Lein of New York, formerly of the USSR took first place. IM Edmar Mednis failed in his quest for the GM (which he earned later) title, but he had a great tournament.

Philipp Hirschfeld

    
The better known first class players of the City of London Chess Club in the 1880s were George MacDonnell, Bernard Horwitz, James Mason, William Potter and Joseph H. Blackburne. Today we are going to meet a much lesser known but at the time a prominent club member, Philipp Hirschfeld. 
    Philipp Hirschfeld (October 2, 1840 0 October 4, 1896) was a German player and theoretician. In 1873 he took up permanent residence in London which explains his membership in the city’s chess club. At the club he was a frequent analysis partner of Johannes Zukertort. While residing in London he regularly lived a few months of the year in Berlin which is where he died. 
    He was, apparently, a far better player than we know! Chess metrics assigns him a highest ever rating of 2600 in 1865 and between 1862 and 1866, he was ranked #4 in the world 8 times, though it must be added that those lists contained very few players, 20 or less. 
    Hirschfeld was born in Konigsberg, Prussia, and came from an affluent background. He learned the game of chess as a child in Konigsberg and by the time he went to Berlin in 1859 to study, he was already a very strong player and theoretician. He was on the editorial department of the Deutschen Schachzeitung, where he published analysis of opening theory. 
    In 1863 Hirschfeld finished his studies and joined his father's business. In London, he founded the Konigsberg Tea Company, with branches in Konigsberg, Moscow and China. 
    Hirschfeld's profession left him no time for international tournaments, but on his business trips he met up with the best players of his time and occasionally contested matches with them. 
    In 1865 he drew a match with Ignaz von Kolisch and in 1865 he lost a match in Moscow against Sergey Urusov. Hirschfeld also played individual games against Steinitz, Lowenthal, Horwitz and De Vere. 
    According to the Chessmetrics website his best historical Elo rating was 2600, which he attained in October 1864. Between 1862 and 1866 he was ranked 4th in the world. 
    His opponent in the following game was Ignatz von Koliscj (1837-1889,52 years old). He was born in Pressburg (now Bratislava in what is modern-day Slovakia). 
    During the period 1859-1868, he was one of the top five or six players in the World. Chessmetrics ranks him the #1 player in the world several times between 1867-68. Kolisch is nit appreicated today, but he defeated Danieal Horwitz and Thomas Barnes and drew with Adolf Anderssen in matches in 1860. The following year he played Anderssen again, narrowly lost and drew Louis Paulsen in a match. In 1863, he challenged a retired Paul Morphy who declined to play. 
    Kolisch opened a bank in Vienna in 1871 and within ten years became a very wealthy man. He continued to support chess by financing the great tournaments.

A Classic Capablanca Win

    
The year 1918 was a rough one because it was heavily influenced by World War I plus the Spanish Flu epidemic which resulted in life expectancy at birth in the US dropping by almost 12 years to a scant 26,6 years for men and 42.2 years for women.
    Opha Mae Johnson (1878-1955) was born in Kokomo, Indiana and graduated as salutatorian of her class from the shorthand and typewriting department of Wood's Commercial College in Washington, DC in 1895. 
    As far as is known, she didn’t play chess, but on August 13, 1918, at the age of 39, she joined the Marine Corps Reserve making her the first women to enlist in the Marine Corps Reserve during World War I. 

    Her first duties were as a clerk at Headquarters Marine Corps, managing the records of other female reservists who joined after she did. She was soon promoted to sergeant and was the highest ranking woman in the Corps during her time in service. 
    At the end of World War I the Corps, like all services, women were slowly released from duty and she became a clerk in the War Department and worked for the Marine Corps as a civil servant until retiring in 1943. Semper Fi, Sergeant Johnson! 
    New York 1918 was originally planned as an 8-player double round tournament, but the nefarious Norman T. Whitaker began a game a day before round 1, became ill and withdrew. 
    Round 1 saw the most famous game of the tournament when Frank Marshall sprung his prepared variation of what has come to be known as the Marshall Gambit against Jose Capablanca who managed to win anyway. 
    In Round 2, Marshall lost againt, this time to Oscar Chajes and as a result Marshall was unable to overcome his bad start. 
 
     
    The loser of today’s game, which features some interesting tactical play, was John S. Morrison (1889-1975) from Toronto. He was Canadian champion in 1910, 1913, 1922, 1924, 1926 and shared first place in 1931 with Maurice Fox won the playoff. In 2000, he was inducted posthumously into the Canadian Chess Hall of Fame. 
    The fact is, both players deserve credit for a well played game. The tactical analysis with Fritz assigns Morrison a credible Weighted Error Value of 0.39 while Capablanca performed at a very precise 0.39.

Sacrificing the Exchange

    
As Rudolf Spielmann explained it the chess pieces, like stocks, have two prices: the par value and the quoted rate. The par value is the value assigned by the company that issues it. The quoted price is the current market price meaning it’s the actual price you can buy or sell it for. 
    Chess pieces are the same. For example, the par value of a Rook is 5 Pawns while the par value of Bishops and Knights is 3 Pawns. However, it’s the market, or relative value, that is the decisive factor. In some positions a Bishop or Knight might be worth more than a Rook. It all depends on specific positional and tactical factors. 
    How do you know when the sacrifice of the exchange is feasible? In The Art if Sacrifice in Chess Spielmann gives a number of guidelines and their exceptions and ends up saying you shouldn’t worry about them because, “With a little practice, (the student)will soon be able to grasp all these circumstances instinctively when they arise…” as well as a sound positional judgment. 
    Here’s an example of what Spielmann was talking about. The game was played in an event which, like the winner Hans Fahrni (1874-1939) has been long forgotten. 


     Fahrni was born in the Austrian-Hungarian empire city of Prague which today is in the Czech Republic. It's not certain when he went to Switzerland, but from there he eventually emigrated to Germany.

A Small, Unimportant Tournament in 1937

    
Following Hitler’s appointment as chancellor in 1933, the Nazis transformed Germany into a one-party dictatorship that implemented racial, political and social policies. German Jews felt the effects of legislation that transformed them into outcasts and enemies of the state. 
    When 1937 rolled around the Aryanization of the economy started when Jewish business owners were forced to sell their businesses, in most cases at proces considerably below their valus. Additionally, Jews were prohibited from working in any office in Germany. 
    Buchenwald concentration camp opened and yhe first 300 prisoners arrived on July 16. By the end of the month, there were 1,000 inmates and the number climed to 80,000 in March 1945. 
    While that was happening in Germany, in the U.S. the Neutrality Act of 1935 expire, but it’s replacement did include a concession to President Roosevelt that permits Allied nations to pay cash for American goods and then transport the goods in their own ships. 
    Roosevelt tried to warn the world of the growing threat to international security that was being jeopardized, but he was accused or trying to circumvent the neutrality laws of America. In late 1937, Germany and Japan signed a military pact. Anf the Japanese Army launched the massacre of Nanking and ot’s estimated that over 300,00 people were brutally murdered. 

    Against that backdrop a long forgotten small and unimportant double round tournament was played in the three cities of Bad Nauheim, Stuttgart and Garmisch.   

    The four players were the world champion Max Euwe, former world champion Alexander Alekhine, former world champion challenger Efim Bogoljubow and German champion Friedrich Saemisch. Shortly after this event, Alekhine won a rematch against Euwe for the world championship.

Play the Clemenz Opening!?



    
The Clemenz Opening (1.h3) is named after Hermann Clemenz (1846–1908) an Estonian player who played it in a tournament in St. Petersburg in 1873. He was born in Dorpat which today is Tartu, Estonia. He began his chess career in his native town, then lived in St. Petersburg, where he participated in several tournaments. 
    The opening achieves nothing in terms of development or control of the center and it makes no attempt to exploit white’s first move advantage. By playing in the center and gaining a slight lead in development black can try to exploit the fact that white has wasted time with 1.h2, bit there is no refutation. The Clemenz is probably best described as indifferent. 
    Nevertheless, IM Michael Basman has experimented with it and sometimes follows it up with 2.g4 as in the Grob Attaxk (1.g4) or 2.a3 followed by a quick c2–c4, a line that has been dubbed the Creepy Crawly or the Global Opening. The 1990 Great Britain Championship was held in Eastbourne anf was won by James Plaskeyy with a 9-1 score. 
    The participants in this game were: Michael Basman (2370) who finished wit a 6-4 score which left him tied for places 22-32 (out of 74) and Niall Carton (2220) who scored 5-5 and tied for places 46-51.

Viktor Goglidze

    
Yesterday saw a swath of cold drizzle 250 miles wide and 800 miles long that hung around all day. It was a good day to browse some old chess books. The one I selected was The Soviet School of Chess by Kotov and Yudovich. 
    It was first translated from the Russian and published by the Foreign Languages Publishing House (Moscow) in 1958. If you can find it, this original edition is the one to get. 
    It’s full of propaganda, but it contains bios of many of the older Russian players. Unfortunately many of them have been deleted from the new editions, for example, Bondarevsky, Levenfish, Korchnoi, etc. In my first edition, there is an entire chapter on Alekhine, who the authors claimed was Russia’s greatest player; it’s missing from later editions. 
    One of the old Russian Masters in my book is Viktor Goglidze (November 27, 1905 – September 15,1964, 58 years old) who was awarded the IM title in 1950.
    In 1925, at the age of 20, he won the championship of Tbiliai in where he displayed a good understanding of positional play and he demonstrated the ability to put up a tenacious defense. 
    After a number of major successes in local tournaments he fought a stubborn and thrilling match against Nikolai Grigoriev which he lost by a score of +4 -5 =1. Taking into account the lessons he learned from that match which disclosed shortcomings in his play, in 1930, after making a good showing in tournaments in the Ukraine, Uzbek and other local events, Goglidze beat Vladimir Nenarokov 7.5-4.5 in a classification match and so gained his Soviet Master title. 
    Shortly before the outbreak of WWII he was awarded the title of Soviet Honored Master and in 1950 a publishing house in Tbilisi published a book of his best games.
 

 
    His opponent in the following game was Vsevolod Rauzer (1908-1941, 33 years old) who was the Ukrainian champion in 1927 and joint champion in 1933. After 1937, ill health brought Rauzer's playing career to an end. Confined to a mental hospital, he died during the siege of Leningrad in 1941. His contributions to opening theory influenced play long after his death. 
    The game starts out slowly, but what looks like a small slip by Rauzer quickly proves to be into a disaster. When black resigned he could have played on on hopes that white would botch the win.

Levenfish Plays Like Stockfish

    
In describing Levenfish’s play in The Soviet School of Chess, Kotov and Yudovich wrote, “Levenfish’s style in the middlegame is universal. He has an excellent command of the methods of positional maneuvering and a keen grasp of strategy...His chief strong point however is tactics. A resourceful tactician, he plans complex and disguised combinations, foresees combinational attacks long ahead of time, sets ingenious traps and conceives combinational blows which at first glance appear impossible.” 
    Other terms used to describe his play include terms such as smashing attack, a stunning blow, a sledge hammer blow, etc. Who wouldn’t want to play over his games? Unfortunately no collection of his games exist in English. 
    Awarded the Soviet GM title in 1950, Grigory Levenfish (1889-1961) was born in Poland. He was Leningrad champion in 1922, 1924 and 1925 (jointly). He won the USSR Championship in 1934/35) (jointly with Ilya Rabinovich) and 1937. 
    He drew a match with Mikhail Botvinnik (+5 -5 =3) in 1037, but that was to be the last major success of his chess career although before the war he won a match against Vladimir Alatortsev in 1940 (+5 -2 =7). 
    As mentioned, Levenfish's play was marked by elegant combinations, unexpected tactical blows and deep endgame analysis. Chessmetrics estimates his highest ever rating to have been 2677 which came in 1939 and his best world ranking to have been #9 in 1938.
    Unlike Alekhine, Bogoljubov, Nimzovich and Rubinstein, he was one of the few pre-revolutionary masters who didn't end up abroad. He successfully passed on his knowledge to the first generation of young Soviet players, authoring a book on openings and along with Smyslov, a book on Rook endings. 
    In the following game his opponent was Vyachesvlav Ragozin (1908-1962), another Soviet GM, both OTB and in correspondence play. Ragozin won the 2nd Correspondence World Championship (1956-1959. For many years he served as Botvinik’s sparring partner. He was also active in FIDE affairs, edited Shakhmaty v SSSR magazine and wrote an excellent book on first Botvinnik - Tal Match in 1960. Ragozin died in Moscow in 1962 while compiling a collection of his own games. His friends completed the book which was published in 1964.

J.J, O'Hanlon

    
John J. O'Hanlon was born in Portadown, a town in Northern Ireland and he passed away in Dublin on February 20, 1960. He was the Irish Chess Championship nine times, the first time in 1913 and the last in 1940. He also played in several British championships. 
    In international play O'Hanlon’s successes included sharing 1st with Max Euwe at Broadstairs in 1921 and tying for 1st–3rd with Marcel Duchamp and Vitaly Halberstadt at Hyeres in 1928. He also played for Ireland in unofficial and official Olympiads at Paris 1924, Warsaw 1935 and Buenos Aires 1939. 
    Poor health which had prevented his taking part in tournament play for a number of years, but at the time of his death he was overhauling his opening repertoire in preparation for the 1961 Irish championship. After his death a series of five tournaments in his memory were played at the Dublin Chess Club from 1960 to 1965 where he had been a member. 
    O'Hanlon was popular with Irish players and non-players alike as well as players in places like Hastings, Amsterdam, Moscow, Prague and Munich because of his gentlemanly manners. In his youth he was an oarsman who won trophies at regattas all over Ireland. In addition, he was a strong long distance swimmer. 
    The Irish Chess Union was founded in 1912 and O'Hanlon won the first two. He played in every championship, except in 1927, from 1913 to 1956 and on his last appearance he was eighty years old. 
    The First Irish Chess Union Championship was held in 1913 even though there had been a competition for the title during the period 1865 to 1893 when a number of different organizations had organized Irish Championships. 
    As a result of his play in England he had contact with the German master (who was a resident in England for many years) George Shories and towards the end of 1912 they played a series of 19 friendly games while Shories was on a visit to Ireland. O’Hanlon won 7, drew 1 and lost 11. It was those games that sharpened O'Hanlon's play and prepared him for his attempt to win the Irish championship in 1913. 
    In the following game O'Hanlon's opponent gets mauled. They were to play is a 5 game match to determine the Irish champion, but after O’Hanlon won the first three the match was concluded. 
    Ronald George Doxpn Addey (1882-1956) was a civil engineer employed by the local government in the northwest of Ireland. He was a notable player and around the time of World War One his name regularly appeared in tournaments. 
    "Mr. Dixon Addey belongs to Castlebar and is undoubtedly the best chess player in the West of Ireland. He has competed four times in the British Chess Federation tournaments. The first time was in 1909, when he entered the first class, but, not being accustomed to tourney play, he did not make as good a score as his play deserved. In 1910 he competed in the first class at Oxford, making a better score. In 1912 he played in the first class at Richmond and tied for third prize. Last year he competed at Chester in the major open tournament, and tied for fourth place." (Belfast Newsletter, May 6, 1912)

Lhamsuren Myagmarsuren

    
The Wikipedia Free Encyclopedia only lists about two dozen Mongolian players, but the first internationally known player was Lhamsuren Myagmarsuren (born February 17, 1938). 
    He was awarded the International Master title in 1966 and his peak rating was 2380 which he achieved in 971. He qualified for the the Interzonal tournament in Sousse, Tunisia 1967 where he finished with a 6.5-14.5 score and tied for 19th place (out of 22) with IM Miguel Cuellar of Columbia. 
     Myagmarsuren was the Mongolian champion in 1965, 1980, 1981 and 1982 and played for Mongolia in the Chess Olympiads from 1960 to1982 where at Leipzig in 1960 he won an individual gold medal at fourth board with a +14 –1 =5 score.  
    His opponent on the following game was Julio Garcia Spticco (1930-2020) of Bolivia. An educator of some reputation. If you read Spanish there is a nice tribute to him HERE. It’s interesting to compare the N’s. White’s N maneuvers accomplish something whereas black’s do not.

An Intuitive and Spectacular Sacrifice by Bronstein

    
Intuition is a form of knowledge that appears in consciousness without obvious deliberation. Hunches (feelings or guesses based on intuition rather than known facts) are generated by the unconscious mind after rapidly sifting through past experience and cumulative knowledge. “Gut feelings” tends to arise quickly, without awareness of all of the information. 
    David Bronstein (1924-2006) was not only a great player, but a great author. In 1951 he drew a world title match against Botviinik; he was probably warned by Soviet authorities that he had better not win. 
    In the following rather well known game Bronstein intuitively sacrificed a piece for two Pawns with the idea that his Pawn center would restrict his opponent’s pieces and that would compensate for his opponent's small material advantage. 
    His opponent, Ernst Rojahn (1909-1977), was born in Tonsberg, Norway and was Norwegian Champion in 1945 and 1958. He played in the Olympiads in 1939, 1952, 1966 and 1958. The game was played in the qualifying round of the 1956 Olympiad held in Moscow.

An Early Compiter Tournament

    
In 1980 we could buy chess computers. For example, there was the Voice Chess Challenger, The First Thinking Chess Game That Speaks To You. It played 40 openings consisting of 1,200 moves. On some settings it it displayed the best move and it could play itself. You could also set up problems. It had 10 levels of play. The response time for levels 1-9 ranged from 5 seconds to 11 minutes per move plus there was am Infinite level. The cost: $245.95 plus $3.00 for shipping and fondling...that’s the equivalent of almost $950 today. The average wage in 1980 was $12,513.46 a year, so the computer was not cheap.      
    One of the best machines was Belle. It was developed by Joe Condon (the hardware) and Ken Thompson (the software) at Bell Labs. In 1983, it was the first machine to achieve master-level play with a USCF rating of 2250.      
    Belle's final incarnation was the third generation that was completed in 1980. It consisted of further improvements to the speed of move generation and evaluation. Depending on the stage of the game, it examined 100,000 to 200,000 moves per second.      
    CHAOS (Chess Heuristics And Other Stuff) was one of the leading programs since it first appeared in 1973 until the mid-80s. It examines only about about 10,000 movrd per move. Its book contains about 10,000 lines. It was slow, but it evaluated positions accurately. Its weakness was that it missed deep tactics.     
    You will, no doubt, find the following site amusing: 7 Fun and Funky Vintage Chess Computers. I had one of the set listed...Boris which appeared in February 1978. 
    The computer came housed in a very nice wooden box measuring 10” x 7” x 3-1/2” and had a small folding board and a travel size set. The cost was $350, that’s nearly $1,700 in today’s dollars. It wasn’t very strong and I eventually threw away the guts and kept the box which today sits on a dresser and holds loose change, watches, keys, etc.      
    In 1978, in San Jose, California, the First Microcomputer Chess Tournament, held in March. To be eligible to the computer shad to be small enough to attend, that is, no phone hookups were allowd, they had to have less than 32K of memory, and be based on 8-bit microprocessor chips.  
  
    In the event of crashes and games which promised to go on and on without any result the TYD could adjudicate the game. Some of the programs running in the old, simple BASIC programming language could not meet the 50 moves in 2 hour time limit and they were paired in a separate matches. Boris, Chess Challenger and Compu-Chess were off-the-shelf consumer products. Commodore Chessmate was a prototype of a consumer product that was expected to be available later tin the year.

Continuing Down Memory Lane

    
Continuing the stroll down memory lane I came across my one surviving game from the 1967 Ohio Championship. That was a memorable year if only because I had survived my 4 years in the military and was discharged at Camp Lejeune, North Carolina. 
    American readers have probably seen the television commercials from law firms wanting to take on cases of people sickened by the contaminated water on the base. 
    Water on the base was contaminated from 1953 to 1987. The water was contaminated only at a couple of dependent housing areas mostly due to the disposal practices of an off base dry cleaner. I received letters from the Marine Corps for about two years. When the letters stopped the television ads by civilian law firms flooded television. Over a half a million claims have been filed, but only a very few have been settled. Lawyers get 20%. 
    1967 was a year of a lot of cultural change, political questioning and personal “liberation”. There was psychedelic rock music, young people in San Francisco were showing an interest in Eastern religions and communal living. 
    Racial unrest resulted in the "Long Hot Summer" and saw racial unrest in cities such as Detroit, Newark and Cincinnati. And, of course, there were protests against the Vietnam War. On a lighter note, Elvis married Priscilla Beaulieu in Las Vegas. 
    A leading German platyer of the 1930s, Ludwid Engels (1905-1967) died in Sao Paulo, Brazil. Former Irosh Champion James Creevey (1873-1967) died in Dublin at the age of 93. The 1956 French Champion French master Pierre Rolland (1926-1967) died in a car accident. IM Stefan Fazekas (1898-1967) died at the age of 69 in England; he was the British champion in 1957 at the age of 59. Sweden’s vteran GM Gideon Stahlberg (1908-1967) died of a liver ailment in Leningrad while there for a tournament. German IN and author Alfred Brinckmann (1891-1967) died in Kiel. Former Hungarian champ (1928) Arpad Vajda (1896-1967) died in Budapest of a gas leak from his oven. 
    Bobby Fischer took 1st place in the US Championship and at Monaco. Anatoly Karpov won the European Junior Championship in Groningen, Netherlands. 
    The 1967 Ohio Championship was held in Cincinnati. There were 56 players and Cleveland Master Tom Wozney scored 6.5 out of 7. He was followed by Experts om Mazuchowski of Toledo and Richard Noel of Cleveland. I have no idea what my score was, but I won the following rip snorter from a local player.

Postal Nostalgia

    
The other day I was going through some of my old games and some played in 1972 caught my attention. For readers who don’t remember 1972, girls were wearing maxi dresses (they reached to the floor, boo!), mini skirts (they reached mid-thigh, hooray!). 
    PONG became the first commercially successful video game. Digital watch made their debut and they were just as clunky as PONG. 
    The popular TV program Star Trek spawned Trekkies and the first Star Trek fan convention took place in New York City. HBO came to television making it possible to watch violence, nudity and obscenity right in the comfort of your own living room. 
    Players lost that year were Victor Soultanbeiff (1895-1972) the former Belgium champion. IM Georgy Lisitsin (1909-1972) died in Leningrad. Sir George Thomas (1881-1972) died in London at the age of 91. Kenneth Harkness (1896-1972) an organizer and creator of the Harkness rating system died on a train in Yugoslavia, on his way to Skopje to be an arbiter at the Chess Olympiad.
    Mikhail Tal won the Soviet Championship. Walter Browne won the National Open (on tiebreaks over Louis Levy) and the National Congress Premier Championship held in Chicago. Browne also won the US Open in Atlantic City. Anatoly Karpov, Tigran Petrosian and Lajos Portisch tied for first in Church’s Fried Chicken International in San Antonio. Finally, on September 2, 1972, Bobby Fischer became the World Champion when he defeated Boris Spassky. 
    It was also the year I played a correspondence game in the Finals of the U.S. Open Postal Championship against USCF Senior Master Arthur Feuerstein, a former (otb) U.S. Championship competitor, with a USCF rating of 2427 which ranked him #14 in the country. Fischer topped the list at 2825 and second place went to Lubomir Kavalek at 2573. I had some pretty good results and my rating was up around 2100. 
    I was primarily a correspondence player though and my postal rating with the USCF (which had absorbed the old Chess Review) was 1280. Feuerstein’s was 1514. The top rated player was a New York player named Reuben Klugman at 1846. 
    Sadly, Feuerstein (born in 1935) passed away on February 2, 2022. 
Feuerstein and I had previously met in 1970 in the semi-finals and I had black. I had a won game (4.75 Pawns to the good) according to Stockfish, but miscalculated a tactical sequence and lost! We met again in the finals and I was determined to do better. The following calamity was the result.
