Rudolf Charousek

  
     The Romantic Era chess was a time when the style of play that emphasizes quick, tactical maneuvers rather than long-term strategic planning. The style was popular in the 18th century until its decline in the 1880s. Romantic players consider winning to be secondary to winning with style! 
     Games during the Romantic Era usually opened with 1.e4 with the King's Gambit and Giuoco Piano to folloed. The era is generally considered to have ended with the 1873 Vienna tournament where Wilhelm Steinitz popularized positional play and the closed game thus ushering in the Modern, or Classical, Era. Then in, the 1930s the Hypermodern Era was ushered in
     One forgotten player of the Romantic E`ra was Rudolf Charousek (September 9, 1873 - April 18, 1900), a tragic figure who was known for his many brilliant tactical games. 
     He was born in what is modern day Lomecek which is near Prague, but as an infant his family moved to Debrecen, Hungary, where he became a naturalized Hungarian. 
     He learned to play chess at to age of 16. While studying law in Kassa, he soon became a strong player and during the 1890s he was was on the top ten players in the world. In 1893 he entered a correspondence tournament organized by the Budapest newspaper Pesti Hirlap, in which he eventually shared first place with Geza Maroczy. 
     Unfortunately, his career was cut short when he died at the age of 26 from tuberculosis. 
 

     In the following game Charousek neat Chigorin, but they played a tie-break match for sole first place which was won by Chigorin, 3-1. A game that I liked (Fritz 17)

Game 11Tahl-Botvinnik World Championship 1960

     Chess has been on the back burner for some time now owing to the post-storm cleanup which also lead to some home remodeling projects.  Plus there have been some obligatory social functions. Hopefully, things will soon return to “normal.” 
     The following game was one of the key games of the match. Botvinnik had the momentum after winning games 8 and 9 to close within one point, but the loss of this game left the normally imperturbable Botvinnik psychologically shattered.
     Tahl’s trainer Koblentz said, “Botvinnik, a man of strong will, who was capable of hiding his emotions, left the stage literally broken, and behind his horned-rimmed glasses his eyes were incredibly sad... At this moment he appeared to me to be very unhappy.” 
 
 
     This game also shows that Tahl also knew how to play positional chess and was more than just a swindler. 
     Calculating tactical lines often fails to be satisfactory. If you have a superior position and there are no immediate tactical threats you must find a way to improve your position. To this end a tentative plan is helpful. You need to draw up a “wish list” of piece setups. You begin with an objective then constantly check it tactically. Hopefully, when your plan is successful, the balance will eventually tip in your favor and you can then launch the decisive attack. 
 
The short version of finding an attacking plan is:
     1) Deciding on a point to attack 
     2) Figuring out what pieces are required and any P-breaks that will be necessary 
     3) Determining the path to get your pieces into the desired positions 
     4) Calculating the exact sequence of moves being sure to include
         possible defensive replies.     
     5) Modifying you ‘plan” as required 
     6) Constantly reassessing the position at critical points. This results in planning an attack, calculating variations and, if necessary, modifying the plan.
     
     One difference between games of the older masters and modern day players lies in items 5 and 6. In older games you often see games where a plan is executed flawlessly and the clash of ideas is clear because the loser did not defend until it was too late. 
     Modern players tend to play games where plans are adopted for a few moves and when the plan becomes obsolete, they toss it out and replace it with a new one. The result is ‘plans’ are often nothing more than short maneuvers, lasting 2-4 moves, designed to place a piece on a better square for example. 
     Modern players rely on intuition and imagination, often accepting positions that older masters would have looked at in horror, as long as the play is dynamic enough. Sticking with a plan too long is often as bad as not having one at all. 
     In the following game both players adopted plans that were only partially completed when they had to be abandoned to meet changing conditions. In this game both players used strategic and tactical weapons against each other. A game that I liked (Fritz 17)

QGD, Symmetrical Defense

     While checking offbeat defenses the QGD, the Symmetrical Defense (1.d4 d5 2.c4 c5) drew my attention. It was analyzed as far back as 1604 but was studied by the Austrian players Hans Haberditz, Hans Muller and Ernst Gruenfeld. Today most theoreticians think white’s advantage is too great and the best black has is a draw. Of course, it can transpose into the Tarrasch variation if white wants to go that route.
     White usually plays 3.cxd5 when it is not advisable for black to play 3...Qxd5 because white gets a big lead in development. Instead, black should play 3...Nf6 intending to recapture on d5 with his Knight. White should be able to maintain the advantage with either 4.Nf3 or 4.e4 though. 
     One of the games I came across was the following amusing Spielmann debacle. 
     Rudolf Spielmann (1883-1942) is well known. His opponent is lesser known. Hans Fahrni (1874-1939) was a Swiss master. In 1892 he was joint Swiss champion. His best results were: 1909, first ahead of Tartakower, Alapin and Spielmann in a Munich quadrangular tournament and first place in 1911 at San Remo. 
     In 1916, he began suffering from psychosis…a generic term for a mental state often described as involving a "loss of contact with reality.” He was hospitalized, but after his release, he had a relapse. 
     In this game Spielmann played a horrible continuation and Fahrni handed him an ignominious defeat.
 
 
     The game was played in the Barmen Meisterturnier A 1905. For the most part, it was a three-way race between Cohn, Swiderski and Forgacs, with occasional challenges from others. 
     The first two were tied for the lead after round 9, but Cohn lost to Swiderski in round 10 and was always a bit behind after that. 
     Forgacs, recovering from a slow start, caught Swiderski in round 11. Round 16 proved critical. 
     Cohn lost to Spielmann, who found his form for this game after losing five in a row! Perlis, going up against tail-ender Pettersson (who had scored one draw in 15 games), slowly frittered away an endgame. That ended their challenges and Swiderski collapsed and lost his last two games while Forgacs won his last two games and took the tournament by a full point. 
     Although Spielmann’s play in the following game was hardly perfect, the game is a good example of why the Symmetrical Defense is not a good choice.

Buddy Simonson

     Albert Simonson (December 26, 1914 – November 16, 1965) was one of the strongest American players of the 1930s and was part of the American team which won the gold medals at the 1933 Chess Olympics. 
     “Buddy” Simonson was born into a wealthy family. His father Leo was a successful wig maker to the Manhattan rich, the theater and movie businesses. His mother, Irene, was from the family that owned the Illinois Watch Case Company in Elgin, Illinois. 
     Simonson showed tremendous skill soon after learning the game. At New York 1933, he scored 7-3 to tie for places with Arthur Dake behind Reuben Fine. This earned him selection to the United States Olympic team at age 18. In the Olympiad at Folkestone 1933 he played first reserve board and scored 3-3, as the Americans won the team gold medal. Simonson's teammates were Reube Fine, Isaac Kashdan, Artheu Dake and Frank Marshall. 
     In the 1935 U.S. Open at Milwaukee, Wisconsin he scored 5.5-3.5 to tie for 4th-6th places. In the first modern US Championship in 1936 Simonson placed second with 11-5 behind Samuel Reshevsky. He scored 11-5 in the 1938 U.S. Championship to finish third behind Reshevsky and Fine. 
     In the U.S. Championship of 1940 he tied for 4th-5th places with 10-6 behind Reshevsky, Fine, and Kashdan. In the 1951 U.S. Championship hefinished tied for 11th-12th, with only 3.5-7.5. 
     Simonson was ranked 6th in the country on the first official rating list issued in 1950. Simonson served with the Army during World War II, attaining the rank of Sergeant. Simonson was very skilled at card and board games, but had a serious gambling problem. 
     He was married three times, and fathered three children. Simonson was a colorful character in U.S. chess history, but little is really known about him. 
     Arnold Denker sheds a little light on the real Simonson in his chapter on the man he called A Daring Young Man on the Flying Trapeze in the delightful The Bobby Fischer I Knew. Denker wrote that Simonson burst onto the New York chess scene like a meteor and then disappeared almost as quickly. But, during his short stay, he won many honors as a player, as a problemist and as a member of the U.S. team at the Folkestone Olympiad. 
     According to Denker, the high point of Simonson’s career occurred in 1936, where only a final round defeat prevented him from winning the first modern US Championship. After that setback, his interest in chess seemed to wane. He did well enough in the 1938 and 1940 championships, but his comeback attempt in the 1951 fixture ended catastrophically, when he shared 10th – 12th places. Denker went on to fill in some of the details and ends the chapter on Simonson describing himself sitting at Simonson’s funeral in the All Souls Unitarian church in New York City thinking, “What a waste.” 
     Physically, Denker described Simonson as a young man as bring tall and shy, always with the slicked-back hair style men wore in the 1930s, well-cut clothes accompanied by an umbrella draped over his arm. 
     According to Denker, if Simonson had chosen a career in chess, there was no telling how far he could have gone. Unfortunately, like many young men who were handed a fortune and never compelled to work, he had no appreciation of it and piddled it all away. Simonson had a restless nature that caused him to jump from one thing to another without ever really accomplishing anything. He became bored with chess and took up pinochle, bridge, gin, poker and backgammon, always willing to gamble on the outcome and always with the very best player he could locate; he nearly always lost. 
     $429,000. In 1933, at age 19, that is the equivalent of how much Simonson collected for his first annuity that had been left to him by Grandpa Elgin. Actually it was $25,000, but $25,000 went a lot further in those days. 
     He was to receive many of these annuities but always, after paying off gambling debts, there was little left. Denker described how on occasions loan sharks had threatened to break his legs and how Simonson often sold off ‘futurities’ on his annuities for as little a $0.25 on the dollar. 
     Simonson also had a habit of pulling practical jokes on people and that sometimes made him enemies. 
     By the late 1930s he needed money and founded a direct mailing business that turned out to be quite successful. This prompted him to get married, but more gambling debts soon caused his wife to leave him. 
     After WW2 broke out Simonson was drafted and, as Sergeant Simonson, ended up in England. After the war he married an English woman, but that marriage did not last long and when it ended he returned to the U.S. where he married a third time, also short-lived. 
     Always a chain smoker, his health declined as his emphysema worsened and while on a trip to San Juan in mid-November, 1955, shortly after his 51st birthday, he passed away. 
     Held at the Hotel Empire in New York in August of 1951 and directed by Hans Kmoch, no players were seeded directly into the championship finals, but competed in four, six-player preliminary sections. Mengarini, Horowitz, and Shainswit qualified out of Group A, while in Group B, Bernstein and Reshevsky qualified and Santasiere advanced over Shipman by way of a coin toss tie breaker. Evans, Seidman, and Simonson qualified out of Group C, and Pinkus, Pavey, and Hanauer qualified out of Group D.
 

 
     This would be the only U.S. championship prior to the emergence of Bobby Fischer in which Reshevsky would play but not place first. A game that I liked (Fritz 17)

Weinstock Wallops Stenzel

     National Master Solomon Weinstock (1925-2009) passed away peacefully at his home in New York after a brief illness. 
     He retired from Brooklyn College after more than 20 years as professor of Psychology where h was a distinguished teacher and researcher. 
     Weinstock served in the Army during World War II. After the war, he majored in math and physics and graduated from City College of New York; he received his doctorate in Psychology from Indiana University. 
     He was a strong advocate for civil rights and environmental issues, enjoyed nature, chamber music, traveling and art. 
     Weinstock was a participant in the 1944 US Championship in which he scored 7-10 and tied for 10etg place with Atillio Di Camillo. Weinstock won the Correspondence League of America championship in 1999. 
 
 
     His opponent in the following game was Harold Stenzel (born 1952) who is an International Arbiter. The game was fairly even until Stenzel played 12...Bxa6 which precluded his castling to safety on the Q-side. His final mistake was the loss of time trying to make K-side threats with 15...Qh5. After that he got walloped.

Fischer Was Perfect, Others Weren’t

     Larry Evans once said Fischer’s weakness was overconfidence, stating that it "sometimes causes him to forget his opponents are also capable of finding good moves." Evans’ statement notwithstanding, the 1963/64 US Championship Bobby Fischer made a perfect score of 11-0. 
     Fischer’s first loss in a US Championship to Edmar Mednis had happened in the previous year’s tournament. Evans wrote that “Fischer plays about 50 per cent stronger with white than with black,” adding "It is hard to remember when he last lost with white." But, that’s exactly what happened in a long French Defense in his game against Mednis. 
     As a result of his defeat by Mednis, Fischer arrived at this championship determined not to let it happen again. This tournament was a strong one with only William Lombardy missing from the top rated players. 
 

     Fischer’s rating going in was FIDE 2702. For comparison, the other’s best ratings (either FIDE or national) were: Reshevsky 2621, Benko 2582, Evans 2602, and Robert Byrne 2550, Saidy 2490, Weinstein 2488, Bisguier 2499, Addison 2445, Mednis 2473, Donald Byrne 2434 and Steinmeyer 2425. 
Weinstein circa 1960
     Those ratings may not seem too high by today’s standards, but at the time most garden variety GMs were rated 2500-2600 with a few actually below that, so the championship did have some pretty strong players. Based on ratings though, Fischer was still in a class by himself and was expected to win the event, but what was not expected was the way he did it. 
     He had been studying for five or six hours a day according to friends and was well prepared in the openings as evidenced by his surprising Larry Evans with a King’s Gambit. 
     But, enough of Fischer...others were also playing and they produced some interesting games. Here’s one by Raymond Weinstein. I always liked his sharp style which he demonstrates in this game against Robert Byrne. Note that in this tournament Weinstein did not have a single draw!

Daring Tactics by Anthony Suraci

 
     Anthony Suraci of East Haven, Connecticut played in the 1948 US Championship where he scored +3 -16 =0 and finished in 19th place out of 20. He was the 1951 state champion. Other than that nothing is known about Suraci. 
     However, the July 30, 1964 issue of the New York Times chess column headlined, “An Unknown Becomes Known Through Some Daring Tactics”. 
     So, he was an unknown local player. Chessgames.com has 27 of his games, mostly from the ‘48 championship and a couple of US Opens, the last being in 1962.
     Here is Suraci’s game featuring those daring tactics. His opponent was Harry Lyman (1915-1999), many time champion of New England and the 1957 US Amateur Champion who is remembered as the Dean of Boston chess. He was the uncle of Shelby Lyman. 
     At the time, Lyman was the champion of the Marshall Chess Club and was, himself, a fearless and dangerous tactician. When the two met and both were bent on complications a fierce battle ensued. The symmetrical opening meant a slow start, but things heated up after black’s 13th move.

Gheorghiu Demolishes de Castro

     It’s been quite an ordeal recovering from the recent flooding. Cleanup, replacing lost items and dealing with the insurance company has not left much free time, but a few spare moments here and there have been spent looking around in the 1970s chess world. 
     The year 1973 was filled with events: it saw the birth of the first mobile phone, abortion being declared a constitutional right, and the Battle of the Sexes, the most-watched tennis match of all times, It was a match between Billie Jean King and Bobby Riggs, the two greatest tennis players of the day. King won easily.
     Vasily Panov (1906-1973) died in the USSR at the age of 66. He was champion of Moscow in 1929. Al Horowitz (1907-1973), a leading US players in the 1930’s and publisher of the great Chess Review magazine, died at the age of 65 in New York. Hans Kmoch (1894-1973) also passed away in New York at the age of 78.
     Aleksander Lipenieks (1908-1973) died in Lincoln, Nebraska at the age of 64. He was the city champion 15 times and also published a number of chess books. FIDE President Folk Rogard (1899-1973) died in Stockholm, Sweden at the age of 73. 
     Three-time USSR Champion Leonid Stein (1934-1973) died of a heart attack at the age of 38 in Moscow. And, two-time Yugoslav champion Braslav Rabar (1919-1973) died in Zagreb, Yugoslavia at the age of 54. 
     At the beginning of the year the world’s top rated players were: 1) Bobby Fischer (2780), 2) Mikhail Tal (2660), 3) Anatoly Karpov (2660), 4) Boris Spassky (2655), 5) Viktor Korchnoi (2650), 6) Lajos Portisch (2650), 7) Tigran Petrrosian (2640), 8) Mikhail Botvinnik (2630), 9) Lev Polugaevsky (2625), and 10) Bent Larsen (2620). 
     Walter Browne won the National Open in Las Vegas on tiebreaks over Laszlo Szabo and James Tarjan. He also won the World Open in New York City. Arthur Bisguier won the big Lone Pine tournament in California. Norman Weinstein, age 22, won the US Open, held in Chicago. 
     Bobby Fischer was making news. He was offered a million dollars to play a match in Las Vegas. According to his lawyer, Paul Marshall, Fischer had over $10 million in offers to or advertise, but he turned them all down...it was beneath his dignity to advertise any product. 
     He moved to Los Angles to continue his religious studies with the Worldwide Church of God
     In August, he announced his upcoming plans at a press conference in Beverly Hills, California with the chief lawyer for the Worldwide Church of God standing by his side. 
     In November, 1973, Fischer was the guest of Philippine President Ferdinand Marcos against whom he played an exhibition game that was broadcast on television. It lasted 5 minutes and a draw agreed after 8 moves. 
     Fischer also played Florencio Campomanes, President of the Philippines Chess Federation, a blitz game on television. Fischer won on time. 
     Ourense is a city in northwestern Spain known for its hot springs; they held an international tournament there in January of 1973. 
     From the beginning it looked like Romanian GM Florin Gheorghiu was going to win, which he did. The one point margin of victory was mainly due to defeat of Pal Benko in the very first round. 
 
 
     The tournament produce a number of interesting games, especially miniatures. Here is one of the more entertaining games in which Gheorghiu totally destroys De Castro. 
      Florin Gheorghiu was born in Bucharest on April 6, 1944. He won the World Junior Championship in 1953 and was awarded the IM title. In 1965 he became a Grandmaster. He won the Romanian Championship in 1960 (age 16), 1962, 1964, 1965, 1966, 1967, 1973, 1977 and 1984. At his peak in November 1980, he was rated No. 10 in the world. 
     Edgar De Castro was a Filipino player and International Arbiter and from the begin of 1960s to the mid-1970s was one of the leading Filipino players. Other than that nothing is known about him.
