The Naegeli Syndrome and Chess

   
Dr. Oskar Naegeli (January 25, 1885 - November 16, 1959), was a Swiss player and dermatologist. 
    In the field of dermatology, the Naegeli–Franceschetti–Jadassohn syndrome is named after him. It is a rare condition characterized by reticular skin pigmentation (distinct brown or pink-red areas or raised bumps that form a net-like pattern), diminished function of the sweat glands, the absence of teeth and thickening of the skin of the palms and soles of the feet. One of the most striking features is the absence of fingerprints. It’s caused by mutations of a gene. Treatment is based on an individual's symptoms. 
    Naegeli was the son of the physician Otto Naegeli (1843-1922) and the brother of the \Otto Naegeli (1871-1938) who were prominent hematologists (specialists in diagnosing, treating and managing diseases that affect the blood). 
    He studied at Geneva, Zurich, Munich, and Heidelberg, obtaining his medical doctorate at Zurich in 1909. He worked in Freiburg at the pathological institute. Later he worked at the university dermatological clinic at Bern. His work concerns immunity research in dermatology and the diagnosis and treatment of syphilis.
    Chesswise, he represented Switzerland at the Chess Olympiads in 1927, 1928, 1931 and 1935 as well as at the unofficial Olympiad in 1936 at Munich.
    Naegeli won Swiss Chess Championship in 1910 and 1936. He lost a match to Dr. Ossip Bernstein by a score of 1-3 in 1932 and to Salo Flohr (by a score of 2-4) in 1933. He participated in the strong international tournaments at Berne 1932 and Zurich 1934, both won by Alekhine. 
    In the following game he pulls off a ni8ce win against Lacido Soler (1903-1964) who was one of the strongest players in Spain in the 1920s and 1930s. He won the Catalan Championship in 1924 and1931. He finished second in the Catalan Championship (1926).1 
    In 1926, he won the silver medal in the Catalan team Championships. In 1921, he was co-founder and first chairman of the Barcelona Chess Club. He was also a chess journalist and was the founder of the chess journal Els Escacs a Catalunya.

Fine – Najdorf Match, 1949

    
In the winter of 1948, when it came to the attention of the Manhattan Chess Club that three top foreign players would be spending December in New York, a tournament was put together on short notice. 
    The masters in question were former world champion Max Euwe, Miguel Najdorf and Swedish champion Gideon Stahlberg. Unfortunately, Stahlberg would not be staying in New York long enough to participate, so he declined. His invitation went to Samuel Reshevsky, who also declined. Argentinian master Herman Pilnik found out about the tournament from Najdorf and offered to fill the empty seat and so he did. 
    When it was all over Fine had defeated Najdorf in their individual game and so took first with Najdrof finishing second. Euwe and Pilnik tied for third. 
    After the tournament Euwe went on tour giving simuls while Fine and Najdorf played a little publicized 8-game match. The hard-fought match ended in a draw.
 
    The majority of the games were played at the Manhattan and Marshall chess clubs; Edward Lasker acted as referee. Fine looked like an easy winner when he won the first two games making it three in a row (counting the tournament) that he had taken from Najdorf. Then Najdort rallied winning games 3 and 4 to tie the natch. The final four games resulted in draws. 
    In the following game, the first game of the match, Fine made quick work of his redoubtable opponent.

Carl Ahues

    
The little known German International Master Carl Oscar Ahues (December 26,1883 - December 31, 1968) was the champions of Berlin in 1910 and the German champion in 1929. 
    He was a frequent competitor in international tournaments in his career with his best result probably being Berlin 1926 where he shared 3rd place with Spielmann behind Bogoljubow and Rubinstein. He represented Germany in three Olympiads (1930, 1931 and 1936). 
    Ahues was awarded the IM title in 1950 and after World War II, he lived in Hamburg, West Germany. His son, Herbert Ahues (1922-2015), was a famous chess author composer specializing in two movers. 
    Ahues opponent was Hungarian IM and IA Dr. Lajos Asztalos (1889-1956) who won the country’s championship in 1913. After World War I, he moved to Yugoslavia, representing that country in the 1927 and 1931 Olympiads and the 1936 unofficial Olympiad. He returned to Hungary in 1942. 
    Asztalos became Vice President of the Hungarian Chess Union and Secretary of the FIDE Qualification Committee. Asztalos was a professor of philosophy and a languages teacher. He passed away in Budapest in 1956. The game was played in Kecskemet in1927. 
 
 
    The tournament was made up of 20 players divided into two preliminary sections of ten. The four leaders in each section then engaged in two separate final tournaments.

Alekhine’s Greatedt Game?

 

   
When it comes to picking Alehome’s greatest game it;s impossible because he had so many, but his game against Reti at Baden-Baden, 1925 has to be one of them. It’s been annotated by a lot of GMs including Gary Kasparov. You’ve probably seen it before, but even if you have it’s worth looking at again. 
    Following World War I which ended in November of 1914 no really great tournaments had been held in Germany and so Tarrasch prevailed upon the authorities Baden-Baden, a famous spa city, to host another international tournament...the last had bee in 1870! 
    Unfortunately neither Emanuel Lasker and Jose Capablanca both priced themselves out of the market when they insisted on a large appearance fee which officials were either unwilling or unable to meet. Also invited but unable to accept because of their professional employment were Milan Vidmar, an electrical engineer and college professor, and Geza Maroczy, at the time an auditor with the Hungarian government. Alekhine’s win at Baden-Baden was just the first of great wins to come. The others were San Remo in 1930 and Bled in 1931. A game that I liked (Fritz 17)

Denker Takes On Washington DC Players

    
The really big news in 1944 was  the Allies invasion of Normandy on D-Day, June 6th. The BBC Home Service presenter, John Snagge, announced these immortal words: "D-Day has come. Early this morning the Allies began the assault on the north-western face of Hitler's European fortress.” 
    A number of players were lost that year.

    In news that went almost unnoticed  Denker took part in an unusual exhibition in Washington DC when he defeated a team of ten of the city’s top players on September 16th. They were simultaneous clock games with each Washington player allowed two hours for his first forty moves. It took Denker 5 hours and 15 minutes to finish with +6 -2 =2. 
    Denker displayed plenty of pluck. He was material down in the last four games, but he succeeded in salvaging 1.5 points. The following day Denker gave a regular simul and scored +24 -1 =4. The sole winner was fifteen-year old Hans Berliner who had been the first to first to succumb to Denker in the previous day’s clock match.

Reginald P. Michell, British Master

`
The big event yesterday was the total solar eclipse and my city was right on the centerline of the zone of totality. It lasted from about 2:00pm until 4:30 pm, but the total time the sun was 100 percent covered was only about 3.5 to 4 minutes. That was the most stunning part of the whole experience.
    It did not get totally dark, like 2:00am dark, but was rather like sunset when the sun is below the horizon, but you still see a little glow in the sky. Also, the temperature dropped about 10 degrees. All in all it was a somewhat eerie (and awesome) experience seeing it get dark in the afternoon! 
    Reginald P. Michell (April 9, 1873 – May 19, 1938, 65 years old) was born in Cornwall in SW England. His wife Edith Mary Ann Michell was a three-time British Women's champion. 
    Michell was British Amateur Champion in 1902 and between 1901 and 1911 he played in eight Anglo-American Cable Matches. He was on the English Olympiad team at Folkestone in1933. In 1914 he received a brilliancy prize for his game in the match against Holland in 1914 which is today’s featured game. 
    I was unable to locate any information on the match other than Britain was represented on the top 5 boards by H.E. Atkins, F.D. Yates, T.F. Lawrence, G.A. Thomas and J.H. Blackburne. 
    In the Hastings Congresses Michell scored wins over Sultan Khan and Vera Menchik and in British Championships he defeated Henry Atkins on several occasions. In Margate 1923, he tied for second place with Alekhine, Bogolyubov and Muffang where he scored 2.5-1.5 against Alekhine, Bogolyubow, Reti and Gruenfeld. 
    Chess metrics estimates his highest ever rating to gave been 2565 in 1904 which ranked him number 22 in the world. 
    Michell was a civil servant by profession and strictly an amateur player who was very modest about his chess accomplishments. Consequently, he rarely ever played outside of England and played in the British Championships on his vacations. His play was sound with few mistakes and with no fireworks. 
    His opponent in the following game was Klaas Geus (1878-1959, dates uncertain) who is virtually unknown today. He finished eighth in the 1929 Dutch championship. He also is supposed to have composed some chess problems under the name “J. de Jutter”

James I. Minchin

James I. Minchin (March 12, 1825 - January 18, 1903) was born in Madras, India where for many years he was engaged in the Civil Service in India. 
    The Sepoy Rebellion (1857-1858), an uprising against the British, caught the British by surprise. During that time Minchin sent his wife Mary, who was in poor health due to the climate in Madras, back to England. In due course she returned to India, however the travel, the climate and seven pregnancies had taken their toll and she passed away in Madras, where she had been born, in about 1877.
    Minchin returned to England a wealthy man and was one of the main promoters of the London 1883 international tournament and he also edited the tournament book.
    For many years while he was in India he was a member of the Legislative Council of Calcutta which gave him the opportunity of becoming acquainted with Indian Princes and rulers, many of whom took a great interest in chess. 
    In a letter in the newspaper Morning Post Henry Bird stated that Minchin was " the principal originator in England and India of the great Exhibition Tournament of 1851", but the British Chess Magazine of the day disputed the claim because Minchin’s name was mentioned by Staunton in his tournament book nor was his name mentioned in the list of subscribers. However, the success of the 1883 Chess Congress in London was largely owing to Minchin’s influence with the Indian Princes and particularly with the Maharajah of Vizayanagram, after whom the Minor Tournament was named and who contributed largely to the prizes. 
    The St. George's Chess Club took a leading role in organizing the 1883 event and Minchin, an honorary secretary of the club, was appointed “manager” of the event. 
     Minchin was known as a kindhearted man who was an excellent scholar both in ancient and modern languages and he had a fondness for reading. 
    As for his chess, he was a very tough opponent over the chess board and no one took him lightly. As a member of the St. George's Chess Club he took part in its numerous matches with considerable success. 
    Later in his life when he had experienced the loss of many of his old friends he retired from the London chess scene and went to live near Bournemouth in southern England. There he was elected the president of the Bournemouth Chess Club where he appears to have played only casual chess. He died near Bournemouth, England. 
     In the following game, perhaps an offhand game, he handily defeats Henry Bird, who in 1866 was, according to Chessmetrics, one of the top 5 best players in the world.

Sam Loyd As A Player

    
Samuel Loyd (January 30, 1841 – April 10, 1911) is best known as a chess problem composer, puzzle author and recreational mathematician (someone who does mathematics for entertainment rather than for research or application based purposes). 
    Loyd was born in Philadelphia but raised in New York City. At his peak, from about 1868 to 1870, according to Chess metrics, Loyd’s best rating was 2474 in 1870 and in 1868-1869 he ranked number 15 in the world. 
     He played in the strong Paris 1867 chess tournament with little success, placing 10th out of 13 with a +6 -17 =1 score. Loyd was infamous for being a fibber, a self-promoter and a hustler. Mel Stover, a contemporary Canadian problemist, called Loyd. "puzzledom's greatest celebrity...popularizer, genius. He also called Loyd a huckster and fast-talking snake oil salesman. 
    For a short period of time Loyd collaborated with another puzzle composer, a guy named Henry Dudeney. Then Dudeney broke off his correspondence with Loyd and accused him of stealing his puzzles and publishing them under his own name. Dudeney despised Loyd so intensely that he equated him with the devil.
    After Loyd's death, his son Samuel Loyd Jr. continued his father’s deceptive ways. He dropped the Junior and published reprints of his daddy’s puzzles. 
    The 1867 Paris event that Loyd participated in was his largest and strongest. The city was host to a World Fair that summer summer of 1867anf the master chess tournament was part of it. 
 

    It was a double round affair with an unusual time limit: 6 minutes per move and draws did not count. The US representatives were Loyd and Wilhelm Steinitz who had defeated Adolf Anderssen in a World Championship match the previous year. 
    The event was also organized somewhat haphazardly in that the players met each other, not in scheduled rounds, but according to availability and inclination.
    Loyd’s opponent in the following game was Polish master Samuel Rosenthal (1838-1903) who, following a Polish revolution in 1854m fled to Paris where he devoted himself to a study of chess and became so rapidly proficient that after a year he won the first prize in a tournament held at the Cafe de la Regence. Chess metrics estimated his highest ever rating to have been 2655 in 1885 and from 1873 to 1876 they rank him number 4 in the world.

A Tartajubow Treat

    
Yesterday was a harrowing one owing to rain, flooding, severe weather alerts and power outages, but we were mercifully blessed to have been spared all but an incessant drizzle. I spent some time playing on Chess Hotel
    I like the site because you sign in with a guest name and then choose your time limit or click on the list of available games and start playing. The strength of the players is usually in the low to medium range. 
    There does not seem to be a lot of engine users and some players demonstrate bad etiquette by abandoning the game when they are losing. If they do, you receive a notice and the win. 
    Chat is available, but it’s rarely used. If it is it it’s mostly profanity laced insults that arr quite amusing. 
  In any case, it’s been a while since I have treated readers to one of my games, so here is one that was played yesterday. I played the Blackmar-Diemer Gambit.
   In the gambit white intends (after 1.e4 d5 2.d4) to follow up with f3 intending to obtains a tempo and a half-open f-file in return for a P. White;s hope is that he can achieve rapid development and active posting with a resulting in a quick attack. 
    The G\gambit was originally named after Armand Blackmar (1820-1888) who was born in Vermon. Along with his brother Henry they invented the gambit. The brothers owned a music publishing company that was originally based out of New Orleans, Louisiana, and later Augusta, Georgia. The company became the most successful publisher of music of the Confederacy during Civil War. Armand was best known for the patriotic songs he wrote. Bonnie Blue Flag
    The gambit is considered aggressive, but its soundness is debatable. Back in the old days (i.e. pre-engine) when we played correspondence chess on post cards there were a few amateurs who specialized in it. GM Boris Avrukh wrote that the gambit "may not be fully correct" but cautioned that he "was surprised at just how potent white's initiative could become.” For us amateurs it’s worth a try!

A Complicated Win by George Kramer

    
The 1950/51 Manhattan Chess Club Championship was conduced at a furious pace as evidenced by the fact that some of the club’s strongest players at the time (Sidney Bernstein, Albert Pinkus, George Shainswit and Jack Soudakoff) finished way off the pace. 
    In this year’s championship, unlike his norm of playing recklessly, Arnold Denker, the defensing champion, played steady, but still imaginative chess and finished with 7 wins and 6 draws. 
    Even so, the outcome was not decided until the final round when Arthur Bisguier, trailing by half point, could not penetrate Denker's defense and had to be content with a draw and a second place finish. 
    Bisguier won more games than any of his rivals, but he had had a very poor start with losses to Edward Schwartz and Max Pavey in the first four rounds. Thereafter he simply could not make up his deficit. 
    Because of personal reasons, George Kramer played all but one os his games in advance of his schedule. Unfortunately, due to his moving to Boston Boris Siff was obliged to forfeit several games, but they had no effect on the top standings. 
    A real surprise was the poor showing of George Shainswit, the previous year's co-champion with Denker. His four losses amounted to his poorest showing in the last few years. 
 
 
    The winner of the following complicated game was George Kramer (1929-2014, 93 years old) the 1945 New York State Championship, the 1951-52 Manhattan club championship and the 1964, 1967 and 1969 New Jersey State Championships. He was also Manhattan Chess Club Champion in 1973 and Co-champion in 1974. 
    He tied for 3rd-4th in the 1948 US Championship with Olaf Ulvestad. He was a reserve for the U. team at the 1950 Olympiad, winning an individual bronze medal. 
    Outside of chess he was Dr. Kramer and was recognized by Marquis Who’s Who Top Scientists for dedication, achievements and leadership as a chess player.
    Kramer studied at Queen’s College in New York, earning a Bachelor of Science in 1951. Kramer served in the US Army, from 1952 to 1954. He then continued his education at the University of Pennsylvania where he earned a Master of Science in 1955 and a PhD in 1957, and started working for Exxon (now Mobil) in research and engineering. Kramer also authored several published works, in his professional career. During his more than 35 years with the company, he rose to the rank of senior research associate and research chemist before his retirement in 1994. 
    It’s a little known fact, but Kramer was Samuel Reshevsky’s analysi partner in his competition for the world chess title in 1948. 
    Information on Richard Einhorn does not seem to be available, but in 1945 he was playing first board for the championship wining City College of New York chess team.

A Vicious Attack By Edgar Walther

`
FM Edgar Wather was born on December 24, 1930 and passed awau in Zuricj at the age of 82 on October 23, 2013. 
    Walther gained a measure of notoriety at Zurich in 1959 when he had a winning position against the eventual world champion, but thanks to a stroke of luck, Fischer managed to draw when Walther misplayed the ending. 
    Walther took four national titles: he was Federal Champion in 1949, 1957, 1971 and in 1965 he won the Coupe Suisse. Oddly, he never managed to win the Swiss Championship. The closest he came was in 1965 when he lost the playoff against Marcel Markus after they tied for first. As a long-time member of the Swiss national team Walther played in six chess Olympiads. He was a long time member of the Zurich Chess Club. 
    He was also well known in correspondence chess and he won the Swiss Correspondence Championship twice (1967 and 1971). In the semi-final of the 8th World Correspondence Championship (1972-75), he tied for first and second and in the final he finished 11th. As a result, he was awarded the Correspondence IM title. His highest OTB FIDE rating was 2316. 
    The following game wa splayed in Oldenburg, 1949. While Walther did not obtain a particularly good result, his game against Heemsoth contained a pleasing finale.
 
 
    Hermann Heemsoth (1909-2006) was a German player who was awarded the Correspondence IM title in 1972 and the Correspondence GM title in 1987. He was German Correspondence Champion in 1954 and 1969. 
    It’s interesting to note that three of the Oldenburg participants ended yp living in the United States. Elmars Zemgalis (1923-2014). Originally from Latvia, when the Soviet Union invaded Latvia in WWII he fled to Germany and in 1952 he finally settled in Seattle, Washington. 
    Nicolas Rossolimo (1910-1975) was born in Kiev and moved to Paris in 1929. In 1952 he moved to New York City. I met Rossolimo at his chess studio sometime in the early 1960s. U asked him for a game and he said, “I can’t play for nothing.” I coughed up his $20 fee and we sat down to play on regulation set. 
    After the opening I must have had a pretty good game because he jumped up, walked over to a display case and grabbed a glass board that look like the dark squares were made out of blue butterfly wings and sat it at the end of the table where the sun was shining on it. He then started grabbing pieces off out board and setting them up on the new one. When I asked what he was doing he said, “I want to play on this board.” I think he set up the position correctly, but in any case I lost quickly. 
    Povilas Tautvaisas (1916-1980) was born in what is now Belarus. Following the Second World War as a displaced person he eventually via Germany made his was ti the Chicago area.

Smyslov Pulls Kottnauer's Strings

    
The tournament held at Groningen, Netherlands from August 13 to September 7, 1946, was a watershed in chess history. Not only was it the first major international tournament after World War II, it marked the first time the Soviet Union sent a team of players to a foreign event. Their results confirmed the growing recognition of the great strength of Soviet players. Of the Soviets, only Alexander Kotov had a middling result, but he defeated both of the top finishers.
    Mikhail Botvinnik and Max Euwe were in a close race to the end. Botvinnik had a lead much of the way, but successive losses to Kotov and Yanofsky in rounds 14 and 15 let Euwe go ahead by a point. However, Euwe then drew three in a row while Botvinnik won three in a row to pull ahead by a half point going into the last round. 
    In the last round Botvinnik’s nerves tool over and he was outplayed by Najdorf, but Euwe blundered and lost a drawn position against Kotov and as a result Botvinnik and Euwe tied for first. 
     For Botvinnik, it was his first outright victory outside the Soviet Union and for Euwe, it was his last great international success. 
 
 
    As for the American representative, US Champion Arnold Denker, he had been playing non-stop since the previous year and his even score was respectable, but deeply disappointing for him personally. 
    Denker’s collapse started in round 11 when he e\suffered the worst mental blackout of his career against Euwe. Denker was tied for third with Smyslov at 7-3 he had already drawn (Botvinnik, Smyslov and Najdorf) or defeated (Szabo) then leaders. 
    Then against Euwe he reached a winning position, but at move 47 he was told that there was a Transatlantic phone call from his wife which he took because he had plenty of time on his clock. Mrs. Denker informed him that while he was out of the country that Reuben Fine and Samuel Reshevsky had conspired against him and convinced Maurice Wertheim, captain of the US team in the upcoming match against the Soviet Union to play on the top boards even though Denker was US Champion. 
    When an angry Denker return to his game against Euwe, he blundered on move 47 and then on move 48 and had to resign on move 52. He proceeded to score only 2.5-5.5 in the rest of the tournament. 
    By the way, the US team (Reshevsky, Fine, Denker, Horowitz, Kashdan, Steiner, Pinkus, Kevitz, Dake and Ulvestad) got crushed by the Soviets (Botvinnik, Keres, Smyslov, Boleslavsky, Kotov, Flohr, Ragozin, Bondarevky, Lilienthal and Bronstein) by a score of 7.5-12.5. Only Kashdan, Kevitz and Ulvestad managed to score a win for the US and Denker lost both of his games to Smyslov. 
    In the following game we see Kottnauer reach a position where everything looks safe, but in reality Smyslov was pulling the strings when he exploited a seemingly innocuous pin.
    For Denker in his game against Euwe, this game would have been a good example of why attention is required right up until the opponent resigns. Only three moves before the end Smyslov still could have allowed his opponent to get right back into the game.

A game that I liked (Fritz 17)
