Byrne Bashes Stein

     The year 1967 is memorable to me because it was the year I returned to civilian life after four years in the military. 
     We lost a lot of players that year. One of the leading German players in the 1930s, Ludwid Engels (1905-1967), died in Sao Paulo. The 1933 and 1934 Scottish champion James Creevey (1873-1967) died in Dublin and the 1956 French champion Pierre Rolland (1926-1967) died in a car accident. 
     The 1957 British champion Dr. Stefan Fazekas (1898-1967) died in England and Swedish GM Gideon Stahlberg (1908-1967) died of liver disease in Leningrad. German master and author Alfred Brinckmann (1891-1967) died in Kiel, Germany. And, finally, the 1928 Hungarian champion Arpad Vajda (1896-1967) died in Budapest as a result of a faulty oven leaking gas. 
     In April, Bobby Fischer took first place at Monaco. When his trophy was presented to him by Prince Rainier and Princess Grace, being the odious snot that he was, Fischer refused to pose for a photograph with them. 
     At the Sousse Interzonal in Tunisia in October Yugoslav GM Milan Matulovic took back a losing move against Hungarian GM Istvan Bilek. Matulovic played his move, but then took it back after saying J'adoube, which he should have announced before adjusting the pieces. Bilek protested to the arbiter who allowed the corrected move to stand. The incident earned Matulovic the nickname "J'adoubovic."
     Bobby Fischer was playing in the Sousse Interzonal. He had a lot of games to play in succession as a result of the organizers rescheduling his games around his religious holidays and Sabbath. At the time he was a member of the World Wide Church of God which observed the Jewish holidays and Sabbath. Because he had so many games to play in a row as a result of the rescheduling, he protested and forfeited his game against Soviet GM Aivars Gipslis. The organizers would not let him replay the forfeited game and so Fischer withdrew. 
     But, enough of Bobby Fischer! Let's take a look at the international tournament held in Sarajevo, Yugoslavia in 1967. The Sarajevo tournaments in the past had a bad reputation because of the large number of draws, but this tournament was different...it was a real battle and until the last move was made it wasn't clear who the winner would be. 

     Among the GMs was the Soviet Champion Leonid Stein who from the very beginning was in the leading position, but he was closely pursued by Borislav Ivkov, Robert Byrne and Dragoljub Ciric. 
     In the first half of the tournament Byrne was among the leaders, but he lost to Nikolic in an easily won position and with that loss he dropped out of contention. Ciric also lost an important game against Stein. Ivkov was in the fight when Stein lost to Byrne three rounds before the end. Stein's loss made it a dramatic race for first. 
     After his defeat Stein then drew with Tringov and going into the last round it was Ivkov who was leading by half a point. In the last round Ivkov drew with Ciric while Stein defeated one of the tailenders, Vladimir Kozomara, and so Ivkov and Stein tied for first. 
     The following game was Byrne's victory over Stein. In order to beat back Byrne's K-side attack, Stein exchanged his Q for two Rs plus a P which theoretically gave him a slight material advantage. However, the lesson to be learned from the game is that in all cases of unbalanced material, positional considerations can nullify a material advantage. 
     In this game, factors such as black's difficulties in obtaining a safe King position and problems in getting good play for his Rs and minor piece his allowed the white Queen to strut her stuff and show her mobility on the open board. As a result, white won a P and then managed to infiltrate black's position and expose its tactical weakness which culminated with white winning a piece. 
     Of the two players, Leonid Stein (1934-1973), three time Soviet champion (1963, 1965 and 1966) is better known. He narrowly missed qualifying for the Candidate tournaments in 1962, 1964 and 1967. Tragically, Stein died at the age of 39 of a heart attack in the Rossiya Hotel in Moscow as he prepared to leave for the European championships in Bath, England. 
     In the late 1960s, college professor Robert Byrne (1928-2013) had become a semi-professional player. He won the 1972 US Championship after tying with Samuel Reshevsky and Lubomir Kavalek and then winning the playoff. 
     In 1973 he placed third at the Leningrad Interzonal in 1973 and thereby qualified for the Candidates Tournament. He lost his first-round Candidates' match to former world champion Boris Spassky in 1974. 
     As a 1974 Candidate, Byrne was seeded directly to the 1976 Biel Interzonal where he performed very well, but missed a playoff spot by half a point, sharing 5th-6th places with 11.5-7.5. 
     Byrne was known as a cagey, patient player who favored flank attacks and solid structural defense, avoided Pawn weaknesses and was especially strong in the endgame He died of Parkinson's disease, a progressive nervous system disorder that affects movement.
     I had an opportunity to meet Byrne at the 1975 US Championship and found him to be quiet, reserved and quite pleasant.

It will take some preparation, but he can also threaten the advance of his center Ps. As Jeremy Silman emphasized in his book Reassess Your Chess, white, who is at a strategical disadvantage, must use any temporary imbalance that is in his favore or lose it. In this case, the temporary imbalance is the excellent placement of white's pieces which are poised for an immediate attack on black's King.} 16.

A Long Tactical Chain of Moves by Alekhine

     Avid readers of this blog (that's just a bit of humor) will, no doubt, remember a post I did a couple of months ago that featured one of Richard Reti's games. As I mentioned in that post, I never relished his games. My book Reti's Best Games by Harry Golombek has been largely unread. 
     Reti was among the best players in the world during his prime which was during the 1910s and 1920s. He started out as a classical, but tactical player, who favored openings like the King's Gambit. However, after the First World War his style changed and he became a proponent of Hypermodernism. 
     The following game does not appear in Golombek's book probably because it was "only" a draw. It does, however, appear in Alekhine's collection of his best games...with his usual hype of course. 

     Although the game was a draw, what a draw it was! It features some excellent positional play and Reti salvaging an inferior ending, but more than that, it features a ten move long tactical sequence by Alekhine that is as instructive as it is astonishing. The game was played in Vienna, 1922, which was one of the first great events after World War One. Alekhine's fourth place tie was something of a surprise, but it was only a minor setback in his career.

In my database 6...Bc5 gives black much better results than Alekhine's recommendation of 6...Be7, but I suspect that may be because in many of those games white did not follow up correctly.} 7. Nxe5 { Alekhine says this gives white an extremely dangerous attack in every variation. Again, my database shows that after this move does quite well which is the reason for my conclusion in the previous note.} Nxe5 8. d4 Bd6 {Uusual, but not bad. Black usually plays 8...Bxd4} (8...

Black's N on f3 is attacked and it is apparently forced to retreat to e8 after which black's position is badly cramped. Alekhine gave Reti credit for finding the only move that gave him defensive chances and Reti was also praised for the exemplary manner in which he conducted the defense.} c5 {This excellent move takes advantage of the limited mobility of the B on b3. Should white take the N, because he is not castled black can equalize fairly easily.} 13. Ba3 {One spectator claimed that when Alekhine played this move he banged the B onto a3 so hard that it was heard throughout the playing hall. The move pins the P and leads to some pretty complicated play. At the end of the tactical sequence white ends up winning a P, but that's all!} (13. exf6 Re8+ 14. Kf2 c4 15. Re1 {Best} Qb6+ 16.

Robert S. Brieger

     Texas Expert (Elo 2000-2199) Robert S. Brieger (1925-2012) was primarily a problem composer who authored several books on problems, but he was also played both over the board and correspondence chess and he won the Houston city champion many times.
     As a composer some of his favorite themes were minor promotions, reciprocal Zugzwang and other problem specialties. As a player he reveled in tactical chess.
     Brieger, who learned to play chess at the age of 17, passed away at the age of 86 on April 26, 2012, in Houston. He was born on October 18, 1925 and in 1926, he moved with his parents to a house located in the NW of Houston where he resided his entire life except for brief jobs away from Houston. Besides teaching math in Houston and other Texas districts, he worked two years for Convair Aeronautics in San Diego, California. He graduated with B.S. in Mathematics from University of Houston in 1946 and obtained a teaching certificate in 1951.
     A lover of classical music, he played clarinet in high school and university orchestras and later enjoyed attending concerts and opera. Also later in life he enjoyed all types of ballroom dancing. He loved classical movies and collected his favorites, especially winners of awards in Cannes and Venice, as well as Hollywood.
     The following game was played in the last round of the 1962 U.S. Open which was held in San Antonio, Texas. Breiger finished with a score of +5 -2 =5 (7.5-4.5) and tied for places 20-30. His opponent, George Kane, finished with 6.5 points and tied for places 43-64. The event was won by Antonio Medina of Spain ahead of Pal Benko and William Lombardy.

Here a brilliancy! There a brilliancy! Everywhere a brilliancy!

     When Max Euwe's book Strategy and Tactics was published back in 1937 he used as examples seven games that were played in Moscow, 1935. They were: Lasker-Lisitsin, Botvinnik-Spielmann, Capablanca-Kan, Spielmann-Pirc, Lasker-Pirc, Goglidze-Flohr and Lasker-Lisitsin. Over the years I think I have posted all of those games, but this tournament was jammed packed with even more thrilling games.
     After a month of incessant struggle in what at the time was considered the most interesting tournament of the century, Mikhail Botvinnik, the idol of Russia, and Czech star Salo Flohr garnered the top honors by sharing first. 
     The sensation of the tournament, however, was Old Man Lasker's fine showing. Like Flohr, he did not lose a game and finished in third place. His defeat of Capablanca was the high point of the tournament. 
 
     What was sensational was that Lasker, at the age of 66, was by far the oldest player and a long tournament like this was a test of physical stamina as well as mental alertness and the grand old man gave a truly remarkable exhibition. His performance was considered a biological miracle considering, in the United States at least, in 1935 the life expectancy for men was only about 60 and about 64 for women. 
     Here's a riddle for you. In the United States, Social Security was introduced in 1935 and the retirement age was set at 65 which was higher than the life expectancy! What's with that? 
     It looks like Social Security was designed in such a way that people would work for many years paying into it, but would not live long enough to collect benefits. But, it was argued that because infant mortality was high and that pulled down the average life expectancy, a better measure was life expectancy after attainment of adulthood. It was argued that the majority of Americans who made it to adulthood could expect to live to 65 and if they did, they could look forward to collecting benefits for several years. 
     Capablanca's fourth place finish was considered a good performance although his fans had expected him to finish higher. His lack of serious competition told against him at Moscow. After getting off to a poor start by losing to Rjumin in the first round, he buckled down and aside from his loss to Lasker played good chess.
    In spring 1933 Adolf Hitler had started a campaign of discrimination and intimidation against Jews, depriving them of their property and citizenship. Lasker and his wife Martha, who were both Jewish, were forced to leave Germany in the same year. 
     After a short stay in England, in 1935 they were invited to live in the USSR by Nikolai Krylenko, the Commissar of Justice who had been responsible for Show trials and, in his other capacity as Sports Minister, was an enthusiastic supporter of chess. On March 24, 1935, Lasker announced in Moscow that he was renouncing his German citizenship and would make his permanent home in Russia, where he would organize and direct a chess academy. He stated, "There is a great depression in the science of chess abroad," and the philosophy and psychology of chess would be studied at his academy. 
     He was given a post at Moscow's Institute for Mathematics and a post of trainer of the USSR national team. Lasker and his wife didn't stay in Russia long. In August 1937, they decided to leave the Soviet Union and moved, by way of Holland, to first Chicago,then New York in October 1937. They were visiting Mrs. Lasker's daughter, but they may also have been motivated by political upheaval in the Soviet Union. 
     In the US Lasker tried to support himself by giving chess and bridge lectures and exhibitions, as he was now too old for serious competition. In 1940 he published his last book, The Community of the Future, in which he proposed solutions for serious political problems, including anti-Semitism and unemployment.
     Lasker died of a kidney infection in New York on January 11, 1941, at the age of 72, as a charity patient at the Mount Sinai Hospital. A funeral service for him was held at the Riverside Memorial Chapel and he was buried at historic Beth Olom Cemetery, Queens, New York. His wife Martha and his sister, Mrs. Lotta Hirschberg, survived him. A few years later, Lasker’s sister, Lotta Lasker Hirschberg, died in a Nazi gas chamber. Martha died in Chicago on October 18, 1942. 
     The following game was yet another instructive one from this tournament. It was once superficially annotated by Fred Reinfeld and, as GM Alex Yermolinsky once so astutely observed, looking at old games with today's engines shows that they often were not the one sided thumping the notes would have us believe. This game was hard fought and both sides missed promising continuations.

Brilliancy Prize for Nicolau

     The women's annual event in Belgrade did not favor Women's World Champion Nona Gaprindashvili. In the 1966 tournament she shared first with Alexandra Nicolau of Romania and in 1967 tournament she was surpassed by her fellow Soviet player Tatjana Zatulovska. 
     Gaprindashvili's results were surprising because at the time she was considered absolutely the strongest female player in the world. In this tournament her result was passed off as a merely temporary and a passing relapse from her earlier fine form. Indeed, she didn't lose her crown until 1978 when she was defeated by 17-year-old Maia Chiburdanidze, 
     The top two places were again secured by representatives of the Soviet Union. Tatiana Zatulovskaya (1935-2017), who had been left in the shadow of Gaprindashvili, revived her reputation and scored a major success. However, after the tournament Zatulovska announced that, although she finished first, she was not satisfied with her play and her result was a matter of Gaprindashvili's bad luck. Zatulovskaya emigrated to Israel in 2000. 
     The greatest surprise of the tournament were the results of the young master candidate, 25-year-old Tatjana Belamarich of Zagreb and the veteran Vera Nedeljkovich (born 1929), several times Yugoslavian Champion. So far as I have been able to determine Nedeljkovich is still with us and she would be 92 or 93 years old. Tatjana Belamarich was an unknown in this event and apparently she still is. 

     The following game was awarded the Brilliancy Prize. In it Romanian Alexandra Nicolau (1940-2013), who studied the Chinese language, showed that she could sometimes play like a GM. 
     Born in Bucharest, she was awarded the WIM title in 1960 and the WGM title in 1976. She was Romanian Women's Champion in 1960, 1961, 1963, 1964, 1965 and 1973. She was also Dutch Women's Champion, in 1974, 1976, 1977, 1978 and 1979. 
     She was the daughter of Ștefan Nicolau, a Romanian virology expert. She was introduced to chess at the age of six by one of her brothers, who taught her how to play. 
     Following her participation in a Dutch tournament in 1974, she stayed in the country to further her studies and began playing for the Netherlands. She was awarded permanent residency and later Dutch nationality when she married Kees van der Mije. 
     Previously Nicolau had been involved in some political maneuvering. Earlier she had lived in Holland for several months after a tournament even though she lacked permission from the Romanian government to do so. In 1969 she wanted to study at Leiden University, but she was not allowed to return to the Netherlands and was banned from playing international tournaments. Her ban was removed after pressure from FIDE president Max Euwe. 
     After that she was forced to promise the Romanian secret police that she would return after playing in any international tournaments until 1974. The 1974 Dutch tournament was the first one she played in after her promise to return had expired and she immediately chose to remain in the Netherlands. She won the Dutch Women's Championship in 1974 and again from 1976 to 1979. 
     From the end of the 1950s to the 1960s WIM Edith Bilek (born 1938) was one of the leading Hungarian women's players. Also a correspondence chess player, she played for Hungary in the 2nd Women's Correspondence Olympiad (1980-1982). She was married to the Hungarian GM Istvan Bilek. Her second marriage was to Dr. Krizsan Gyula.

World Politics and a Chess Tournament

 
     On July 26, 1956, Egyptian President Gamal Abdel Nasser announced the nationalization of the Suez Canal Company, the British and French company that owned and operated the Suez Canal since its construction in 1869. 
    Nasser’s announcement came about following months of mounting political tensions between Egypt, Britain, and France. Although Nasser offered full economic compensation, the British and French were suspicious of Nasser who was opposed to their political influence and efforts to perpetuate their colonial domination. 
     In the United States President Eisenhower was worried by the prospect of the outbreak of hostilities as well as possible intervention by the Soviet Union. Consequently, on September 9, 1956, Secretary of State John Foster Dulles proposed a consortium of 18 of the world’s leading maritime nations to operate the Canal. This and international mediation efforts failed. 
     Additionally, in discussions with the United States that took place between August and October, the British hinted that they might resort to force. At the same time in some political intrigue, the British and French were holding secret military consultations with Israel who regarded Nasser as a threat to its security. The result of those meetings was a plan to invade Egypt and overthrow Nasser. 
     As a result, Israel attacked on October 29, 1956, advancing to within 10 miles of the Suez Canal. Under the pretext of protecting the Canal from Egypt and Israel, Britain and France landed troops a few days later. 
     This left Eisenhower deeply concerned about the Soviet Union's intervention just like they had done in Hungary. The Hungarian Revolution which began on October 23, 1956 was a countrywide revolution against the Stalinist government and it was ruthlessly suppressed. It was also the reason a number of Hungarian chess players, including Pal Benko, ended up in the United States. 
     Under pressure from the United Nations Britain and France withdrew in December and Israeli forces departed in March 1957. That month, Egypt took over control of the canal and reopened it to commercial shipping. 
     What did that have to do with chess? It meant the annual traditional Hastings Christmas tournament had been called off in view of the unsettled international situation. 
     Eventually it was rescheduled and it was a four-way fight for first between Svetozar Gligoric of Yugoslavia, Bent Larsen of Denmark, Alberic O'Kelly of Belgium and Fridrik Olafsson of Iceland. 
     Today, O'Kelly is mostly remembered for his contributions to the Sicilian Defense, but at the time he had been collecting a string of first prizes in tournaments and on the January 1957 rating list Chessmetrics puts his rating at 2644, placing him at number 31 in the world. That placed him in a group of better known players like Pal Benko, Wolfgang Unzicker, Oscar Panno and Alexander Kotov.
     In this Hastings tournament, as a result of a loss to Gligoric, he failed to capture first. Gligoric had been playing under par recently, but at Hastings he was in top form. 
     Olafsson, despite personal victory over Larsen, his bete noire to whom he had lost a match for the Scandinavian title, was relegated to a tie for third when he lost to Gligoric in the last round. 
 

     There is little doubt that when you look at the the crosstable the question springs to mind, "Who was Derek G. Horseman?" I posted about him last year and gave his game with Szabo from this tournament HERE
     The following short, sharp encounter features a nice combination by Peter Clarke against Roman Toran. FM Peter Clarke (March 18, 1933 - December 11, 2014, 81 years old) was born in London, England. He was a ICGM and in 1977 he won the British Correspondence Championship. Over the board he finished 2nd on five occasions in the British Championship. 
     Clarke was also a writer and chess correspondent for the London Sunday Times and is best known for his biographies of Mikhail Tal and Tigran Petrosian. Clarke was also an International Arbiter. 
     In the early 1950s, Roman Toran (October 8, 1931 - October 1, 2005, 73 years old) was among the best Spanish players. In 1951 and 1953, he won the Spanish Championship. He won the Gijon International Tournament seven times: 1946, 1947, 1948, 1949, 1950, 1951 and 1954. He also qualified for two Zonal Chess tournaments (1954, 1962). 
     Toran retired from competition in the mid-1970s and devoted himself to journalistic work and chess activism. From 1982 to 1990 he was the FIDE Vice President for Europe, between 1988 and 2000 the president of the Spanish Chess Federation. He published dozens of books on chess, was the founder of several Spanish chess magazines.

Flummoxed By The Borg Defense


     On February 27th of last year I posted about how depressing the last few days had been. It started out drizzling rain before changing over to snow and it was dark, overcast, windy, cold and there was a fine, almost invisible, lake effect snow blowing around outside. It was a good day to say in and play a little chess online.
     Here's a video from a couple of days ago of the ice flowing from a nearby River into Lake Erie:

 

      Things have not changed much from last year, so playing online is what I have been doing the last few days. It's been fun playing one appalling opening and one horrid defense. 
     The opening of choice has been the Desprez Opening (1.h4), an opening that does nothing in either the fight for the center or for white’s development, plus it weakens the K-side. 
     With black my favorite defense has been the Borg Defense (1...g5). That’s Grob (1.g4) spelled backwards. It’s also known as the Basman Defense, after British IM Michael Basman. The move severely weakens the K-side, but according to Modern Chess Openings (MCO), black is only somewhat worse. I'm convinced that against average players it's not all that bad because they often seem to get totally bewildered! 
     In the following game I gave up the Q for not nearly enough compensation according to the engines, but when two average players are playing a 10 minute game things aren't so clear cut!

Same Player, Different Luck

     Here it is Friday and we were blessed to have survived another ugly winter storm that moved from the SW to the NE and stretched 2,180 miles from Maine to Texas. In places it was over 750 miles wide. I think it was a variation of a Panhandle Hook. Shades of the February 2nd storm! 
     As temperatures rose to 55 degrees this one brought, fortunately, only 1 inch of rain, not the 1-1/2 to 2 inches predicted, but it came on top of 10-12 inches of melting snow. Later in the day the temperature began dropping into the teens and the rain changed to freezing rain and then snow. We woke up this morning with 2-3 inches of snow on top of a layer of ice.   
     Thankfully, it was not as bad as what happened to the people in Petropolis, Brazil. Just over 10 inches of rain fell within three hours on Tuesday (almost as much as during the previous 30 days combined) and set off mudslides and floods in a mountainous region of Rio de Janeiro state, killing multiple people, washing away homes, cars and everything else in their path. 
     Petropolis was the site of the 1973 Interzonal tournament that was won by Henrique Meking. Second place was a tie between Lajos Portisch, Lev Polugayevsky and Ewfim Geller. Portisch and Polugayevsky qualified for the Zonal when they eliminated Geller in the playoff in Portoroz. 
 

     Chess Life editor Burt Hochberg was there and wrote that while he and his wife were in Rio de Janeiro he was reading a newspaper chess article and noticed the name of a participant he had never heard of...somebody the article referred to as Mequinho when the headlines screamed MEQUINHO BEATS RESHEVSKY! 
     Mequinho was Henrique Mecking, Brazil's boy wonder, the strongest player on the South American continent and likely the best player South America ever produced. Mecking won the tournament, as Hochberg put it, "...al1 by himself. He did it cleanly, simply by playing better than anyone else." 
     It was a different story for old timers like Smyslov, Bronstein, Reshevsky and Keres; sadly, their star was fading. 
     Poor Reshevsky! Against Soviet player Vladimir Savon, Reshevsky had a forced mate when, in his usual time pressure, he played the last move of the time control, 40.Qxg6 mate...or it would have been a mate, but, alas Reshevsky simply forgot that Savon had a B lurking on b1 and so after Savon snapped off the Queen it wasn't mate at all...Reshevsky had simply blundered away his Q and so he resigned.
     However, in his game against Yugoslav (now Serbian) GM Ljubomir Ljubojevic, Reshevsky didn't miss the mate. Ljubojevic (born 1950) won the Yugoslav Championship in 1977 (tied) and 1982. During his career he defeated just about every top player there was.

The Intriguing Henschel Twins

     The last post was about a virtually unknown player from the Civil War era. Today's is about a couple of virtually unknown twin sisters that participated in the 1944 U.S. Women's Championship: Wally and Kathe (Kate) Henschel. 
     The November 5, 1946 issue of the Brooklyn Daily Eagle called them "intriguing" and stated that they were in their 40s and arrived in the U.S. from Germany "several years ago." 
     The article also stated that Wally Henschel was the champion woman player in Germany and that the sisters, who had been taught chess by their father, had played chess since childhood. In the article Kate conceded that Wally was the better player.
 

     Not a lot of information is available on the sisters, but it is known that they were born in Hamburg in 1893. Wally participated in two Women's World Championships. In Hamburg 1930, she placed 3rd out of 5 players, scoring +4 -3 =1, defeating Vera Menchik in one of their two their individual games. Then in Prague 1931, she placed last with a score of +2 -6 =0. 
 
 

 
     More information seems to be available on Wally than Kate. Wally Henschel attended a high school for girls in Hamburg and began studying music at t at the age of 16. From 1909 to 1914 she studied piano as her first major and singing as her second major. 
     As part of her exam concerts, she played Beethoven and sang Mozart. According to her diploma, her performance in piano playing was consistently rated "very good." 
     After her studies, Wally most likely continued her musical education and passed further qualifying exams years later. In 1927 she received state recognition as a singing teacher and in 1929 she passed the aptitude test for the stage profession in the opera genre. She appeared in public mainly as a singer and when asked about her professional activity and her income before 1933, she stated that she had given a number of recitals in Hamburg. 
     Wally had a position at the Hamburger Tempel on Oberstrasse. where she sang regularly in church services, at weddings, funerals and on holidays and also conducted the children's choir. She earned her main income giving piano and singing lessons.
     Meanwhile, her sister Kathe worked until 1939 in a secretarial position as a secretary at the company Axel Dahlstrom and Co., There, even though she was Jewish, the company not only did not fire her, but even paid her a higher salary.
     Facing the growing restrictions of Jews in Nazi Germany, the sisters began planning their escape. In August 1938, a cousin sponsored their immigration to the United States and by the end of December they had all the necessary papers together. 
     They left Germany on March 25, 1939 with little or no assets. Six days later their passports were blocked because of visa and transport difficulties and it took them several months to get to New York via the Netherlands, England, the West Indies, Central America and Haiti! 
     After relocating to the United States the sisters still faced immense hardships. Wally found it impossible to establish herself as musician or music teacher and the sisters were reduced to being supported by their cousin for four years. Kate eventually found secretarial work while Wally opened a boarding house. By 1944 they were somewhat established and found time to explore the New York City chess scene. 
     Over time Wally had become almost blind in one eye and severely visually impaired in the other and by the mid-1950s she was badly restricted in her ability to work and lived on a disability pension. 
     In 1986, at the age 93, the sisters moved to Miami, Florida to be close to a nephew. Wally died in 1988 and Kate lived until 1990. 
     I was unable to locate any of Kate's games and only two of Wally's. Here is her win over Vera Menchik in the 1930 Women's World Championship.
