A Confession About Capablanca's Games

     In my chess library I have four Capablanca books: Chess Fundamentals and My Chess Career by Capablanca, Capablanca's Hundred Bet Games by Harry Golombek and Capablanca, A Compendium of Games, Notes, Articles, Correspondence, 1lustrations and Other Rare Archival Materials on the Cuban Chess Genius Jose Raul Capablanca, 1888-1942 by Edward Winter. 
     Here's my confession...I have never read them. The reason is that Capa's games never appealed to me; I don't know why. However, of late I have been peeking at the books and today's game feature an in instructive game from the 1916 Rice Gambit tournament that was held in New York City in 1916.
     His opponent was David Janowsky, the guy who is probably best remembered as a punching bag for the greats of his day. That's not fair though because Chessmetrics assigns him a high rating of 2776 in July 1904. On the site's May through September list he was ranked number 1 in the world ahead of such players as Maroczy, Tarrasch, Lasker and Pillsbury. 
     The problem was Janowsky played very quickly and was a gambler both on and off the board. He was a sharp tactician who was devastating with the Bishop pair. 
     Capablanca, himself, said, "...when in form [he] is one of the most feared opponents who can exist". Capablanca noted that Janowsky's greatest weakness was in the endgame, and which Janowsky reportedly claimed to detest. Frank Marshall wrote that Janowsky "could follow the wrong path with greater determination than any man I ever met!" 
     Reuben Fine called him a player of considerable talent, but a "master of the alibi" when it came to his defeats. Fine also noted that Janowsky was sometimes unpopular with his colleagues because of his habit of stubbornly playing on in lost positions. 
     In 1915, Isaac Rice started planning the Rice Jubilee Tournament to celebrate the twentieth anniversary of his discovery of the Rice Gambit, but he died on November 2, 1915. 
     Rice planned to invite primarily American masters and leading European players who might be able to compete despite the war. No reply was received from Alekhine and Marshall refused to compete after a dispute over his fee, but Janowsky was able to make it from France. The event consisted of a round robin with the players with the four highest scores playing a final with the preliminary scores carrying over. 

 

I understand that Capa himself annotated this game in My Chess Career, but I do not have access to his notes. However, Alex Yermolinsky commented on the opening in The Road to Chess Improvement and stated that the game made an impression on him in regards to the Queens opposing each other on b3 and b6.

Chess on IECG

  
Simon Webb
     The International Email Chess Group was an electronically based organization whose aim was to organize, develop and promote the study and practice of international e-mail or server correspondence chess all over the world. 
     It started in 1995 and ceased operations on December 31, 2010 because e-email play had quickly declined in popularity making it impossible to form tournaments in a reasonable time. 
     There were also other problems with e-mail like viruses and spam filters that made playing by e-mail difficult. It was for that reason that IECG stopped its operations and transferred its activities to Lechenicher SchachServer Server which is run by Dr. Ortwin Paetzold, one of the IECG founders. 
     The last IECG World Champion was IECG Senior Master Sergei Bubir from Ukraine. IECG's first World Champion in 1996 was Simon Webb (June 10, 1949 – March 14, 2005), a British IM and Correspondence GM. He was once ranked seventh in the world in correspondence chess 
     On March 14, 2005, the mild mannered Webb, who was living in Sweden, was stabbed to death in his kitchen. Police said that the attack was carried out by his 25-year-old mentally disturbed son, Dennis. 
     According to teammate Per Soederberg they were playing together in the finals of the Swedish Chess League in Malmo and after the game Webb said goodbye and took a train to Stockholm. Soederberg guessed that Webb must have arrived home at about 1am. And, at about that time he apparently had an argument with his son. 
     Dennis had served four years in prison for drug related offenses and his friends said that, unlike his father's placid demeanor, he had an explosive temperament. Police said that Dennis first shoved his father then grabbed a kitchen knife which he dug into Webb’s stomach. 
     Webb's wife, Anna, heard her husband screaming and came out into the hall to see him lying in a pool of blood having been stabbed repeatedly.   Immediately after the stabbing Dennis grabbed the car keys and stormed out of the house and Mrs. Webb called the police and tried to stop the bleeding. 
     Dennis drove at high speed through the suburb of Kallhaell, a 30-minute drive from the center of Stockholm. According to police Inspector Hans Strindlund's statement Dennis crashed the car at about 80 miles per hour into a bus stop and as a result of the crash he suffered a broken nose. 
     Between 2004 and 2009 I played 41 e-mail games on IECG, scoring +5 -7 =29. There were no rules against the use of engines and the top engines were (I think) Fritz, Junior and Rybka. My first tournament in 2004 was entered at my Correspondence Chess League of America rating which was 2000-something. I was unaware that there wasn't any rules against engine use in IECG tournaments and so my 6th place (out of 7) finish with a +0 -4 =2 score wasn't bad because my draws were with one of the aforementioned engines. 
     Looking over the games today reveals that none of them rates a second look. Consequently, let's take a look at one of Simon Webb's games. 

A game that I liked (Komodo 14)

Rubezov's Fatal King Walk

     Lou P. Andvere describes himself as a reasonably strong correspondence player (about 2300+ ICCF) who has written several chess engines. As he explained, these days in correspondence chess a good correspondence player using an engine is always stronger than a lone engine, especially in situations with a material imbalance that are difficult to evaluate. He added, "Correspondence players are a bit like race car drivers. They can’t outrun the car, but that’s not the point - the point is how well do you steer it." 
     Be that as it may, correspondence chess was a lot more fun before engines and it produced games like the following one. 

     Nothing is known of the Soviet correspondence player Anatoly Rubezov except that between 1960 and 1963 he he played, and lost, a game in the 1960 USSR Correspondence Championship to Georgy Borisenko (May 25, 1922 - December 3, 2012) that can be found in several books of chess brilliancies. 
     Borisenko was a Soviet correspondence GM and theoretician who trained, among others, Nona Gaprindashvili, his wife Valentina Borisenko, Viktor Korchnoi, Mark Taimanov and Timur Gareyev. He became a Russian Master of Sport in 1950 and a Russian Correspondence GM in 1966. He won the USSR Correspondence Championship twice, in 1957 and 1962, and came in second in 1965. 
     In the following game Borisenko displays fantastic ingenuity as he forces Rubezov's King on a long walk to its doom. The white King started on e1 and from there went on a journey to g1-f2-e1-d2-c3-c4-d5-d6-e5-e6-f5-e4 and ended up on d5 at which point Rubezov resigned. 
     In the game, at move 13, Borisenko made the sacrifice of the exchange that's often seen in the Sicilian (...Rxf3) and a few moves later makes what looks like a mistake, but was actually a carefully laid plan: a whole Rook down he chases white's King all over the board until there was nothing for Rubezov to do but send off a postcard with the dreaded words, "I resign" or some such. A game that I liked (Komodo 14)
[Event "USSR Correspondence Championship"] [Site "?"] [Date "1960.??.??"] [Round "?"] [White "Anatoly Rubezov"] [Black "Georgy Borisenko"] [Result "0-1"] [ECO "B89"] [Annotator "Stockfish 15"] [PlyCount "74"] [EventDate "1960.??.??"] {Sicilian: Sozin Attack} 1. e4 c5 2.

A Sidney Bernstein Brilliancy

 
Senior Master Sidney Bernstein
     In 1959 gas was 25 cents a gallon, a postage stamp cost 4 cents and you could buy T-Bone steaks for $1.09 a pound. Membership in the USCF was $5.00 a year and Chess Life was published twice a month on newsprint paper,. 
     If you wanted to play, let's say, in the New Jersey Amateur (rated under 2200) that was held in April at the Midway Diner in Hammonton, New Jersey, the entry fee was $5,00. Accommodations were available at the Lake Front Motel (today it's the Red Carpet Inn) for $3.00 a night, $2.00 for double occupancy. The prizes..."many trophies." 
Midway Diner

     Most chess books were under $5.00 and Chess Review was selling folding cloth boards for $1.75 to $4.00. An imported German chess clock could be had for $22.00 (plus $2.20 Federal excise tax) and a wooden set with a 3-1/2 inch King cost $35.00; a wood storage box was included. 
     On October 31, 1959, Mikhail Tal won the Candidates Tournament at Bled, Yugoslavia. More importantly, 1959 was the year I started playing postal chess in Class C (Average) with Chess Review. 
     The year 1959 began with 15-year-old Bobby Fischer winning the U.S. Championship with an undefeated +6 -0 =5 and pocketing a $1,000, a little over ten times that amount in today's dollars. 
     Not surprisingly, Fischer was complaining to the tournament organizers before the tournament even started. He said there were "irregularities in procedures" that could unfairly deprive him of the title. His complaint was that the choosing lots to determine who played whom and when was done in private without the players being present. He said the practice was just unfair and threatened to forfeit his games if the pairings were not redrawn in public. 
a querulous Bobby Fischer

  The tournament officials were adamant. One of the directors was Hans Kmoch, who had double-forfeited Eliot Hearst and Edmar Mednis in the 1956 Rosenwald tournament because neither of them had kept an accurate scoresheet. 
     It was agreed that Fischer's protest had some merit, but the officials were not going to redo the pairings because they had already been published and doing so would only serve to antagonize the other participants.
     They also wisely prepared to deal with Fischer's threat by placing a 22-year-old pre-med student named Anthony Saidy on standby. In the end, Fischer played. 
     According to Edmar Mednis the level of play in the championship, when compared to previous championships, was quite high...as evidenced by the fact that Samuel Reshevsky could only manage third place. 
     Sidney Bernstein agreed, adding that the emphasis was positional play, but that also contributed to a "certain lack of color and excitement." He added that the level of play was higher and that with the rising of the level of play the number of blunders was reduced.    
     Arnold Denker considered the level of play "fairly high,'" but he thought it was a shame that the playing conditions were becoming worse. James Sherwin agreed, calling the playing conditions and prizes "quite unfortunate." 
     In the following game Sidney Bernstein did his part to deal with the lack of color and excitement. He opened with the Orangutan and the play was rather boring until Seidman counterattacked and things got real tactical and Bernstein finished off his opponent with a surprising Queen sacrifice. A game that I liked (Komodo 14)

Fluorescent Lights, Walter Browne and Bobby Fischer

     Fluorescent lights are highly versatile and the type of lighting that you most likely to see in offices, schools and commercial buildings because it's known for its energy efficiency compared to other types of lighting. 
     There are several different types of fluorescent lighting, but what are known as linear fluorescent tubes, the kind that are commonly used in overhead fixtures, are probably most familiar to us. 
     Fluorescent lighting is the result of a chemical reaction inside of a glass tube. Fluorescent lights have a ballast. Its main purpose is to take the alternating current and turn it into a steady and direct stream of electricity. This stabilizes and maintains the chemical reaction that is occurring inside the bulb. 
     From the ballast electricity flows to the electrodes inside the glass tube, which is kept under low pressure. Inside of the tube are inert gasses and mercury which are excited by the electrical current. The mercury vaporizes and the gasses begin reacting with each other to produce an invisible UV light that we actually cannot see with our naked eye. 
     The tube is coated with phosphor powder coating that glows when it is excited by the invisible UV light producing a visible white light. Environmentalists emphasize that because of the mercury it is important to recycle fluorescent bulbs after they’ve burned out. 
     If you look at a large room that's lit mostly by fluorescent lights there's a good chance that you'll see all kinds of different colors coming from them. That's because of something called color shifting. 
     The longer the bulbs burn the more likely it is that the chemical properties change and cause an imbalanced reaction. As a result the lights are less white and not as bright. In order for the fluorescents to reach their full brightness it may take anywhere between 10-30 seconds for warm up. 
     Fluorescent lighting has been around over 100 years, but it doesn't work well everywhere and relying on solely on fluorescent lighting can produce negative ergonomic and health effects
     Aside from the EPA and environmental concerns about broken fluorescent bulbs and their disposal, frequent switching on and off results in early failure.
     Light that comes from them is omni-directional...it scatters light in every direction which is grossly inefficient because only about 60-70 percent of the light given off is being used and the rest is wasted. 
     Prior to 1978 magnetic ballasts were required to operate fluorescent lights and they could produce a humming or buzzing noise. The problem was eliminated with the introduction of high-frequency, electronic ballasts. 
     Ultraviolet light can also affect artwork like watercolors and textiles. Artwork must be protected by the use of additional glass or transparent acrylic sheets placed between the source of light and the painting. 
     More importantly, in a 1993 study researchers found that ultraviolet light exposure from sitting under fluorescent lights for eight hours is equivalent to one minute of sun exposure. 
     Health problems relating to light sensitivity may become aggravated in sensitive individuals. Researchers have suggested that the UV radiation emitted by this type of lighting had led to an increase in eye diseases, most notably cataracts. 
     Other medical professionals have theorized that retinal damage, myopia or astigmatism can also be attributed side effects of fluorescent light. And it's not easy on the eyes! If you have bloodshot or dry eyes it could be because fluorescent tubes n an office space can cause people to subconsciously squint due to the harsh light. The best designs in those spaces soften the light that reaches the ground. 
     players notorious for demanding the light in the tournament room meet their personal specifications were Walter Browne and Bobby Fischer. Browne even went so far as to withdraw from the 1978 U.S. Championship in a dispute over the lighting.
     The 1978 championship would have been Browne's biggest test in the U.S. Championship because virtually all the top players were participating and there was some doubt that he'd be able to win it. 
     The tournament was held on the Southern California campus of the Worldwide Church of God where Bobby Fischer was holed up and several of the players were granted brief audiences with him. 
     At the initial meeting of players Browne made what was by then his familiar complaint about the lighting, claiming it was inadequate and that it could seriously undermine his chances. Most of the players either humored him or ignored him.
     The tournament director was Isaac Kashdan who had run ins with Browne in the past and when Browne bellyached about the lighting Kashdan arranged to have the college's lighting technician meet with Browne to work things out to Browne's satisfaction. 
     A few hours before Round 1, Browne chanced to run into Kashdan and told him the lighting was good enough, but with the proviso that he be allowed to sit at a particular table for the entire event. The players' seating assignments was rotated, but Kashdan agreed. 
     Shortly after that and before the first round started Kashdan was inspecting the tournament room and noticed one of the tables out of line so moved it back. When Browne entered the playing area late and noticed "his" table had been moved from under the spot he thought offered ideal lighting conditions he approached Kashdan who was unaware that it had been Browne himself who had moved the table out of line. 
     After a brief conversation with Kashdan, a belligerent Browne, who accused Kashdan of hating him, stormed out which resulted in him being forfeited against Larry Christiansen. 
Isaac Kashdan
     Later, Kashdan called a meeting of the appeals committee (William Lombardy, Kenneth Rogoff and Andrew Soltis) and Browne presented his case, saying that he would walk out right then if forfeit stood. If the forfeit was erased, he agreed to play Christiansen on whatever day Christiansen and the appeals committee decided. The committee, not wanting to put Christiansen on the spot, upheld the forfeit. Lombardy then tried to convince Browne to continue in the tournament, but it was a waste of time. Browne left. 
     Isaac Kashdan was, unfortunately, involved in another dispute over lighting. This time with Bobby Fischer during the 1971 Candidates Semifinal match played in Denver, Colorado. 
     In a Sports Illustrated article that never got published Kashdan explained how the lights were a problem based on Fischer's demands. It seems Fischer had made a special study of the subject and his specifications called for twenty fluorescent fixtures, each with four daylight tubes, to be twenty feet above the playing surface. 
     The committee in charge of such things made sure his specifications were met, but when Fischer arrived he complained that the lights were...too bright! The electricians explained that fluorescent lights are brighter than rated when newly installed and so Fischer asked for changes which ended up having to be made on a daily basis! Add four blue lights, lower the fixtures three feet, try yellow lights, try soft white lights, etc. Somehow, in spite of Fischer's demands, the match reached a conclusion with Fischer winning 6-0.
     The World Chess Hall of Fame has a fascinating page on Fischer and you can listen to interviews in which Browne, Helgi Olafsson, Viktors Pupols, Larry Remlinger, Aben Ruby, Dr. Anthony Saidy, Yasser Seirawan, James T. Sherwin and Walter Shipman reminisce about Fischer. VISIT SITE

Marshall vs. Manhattan 1941

 
     When the Marshal and Manhattan chess clubs met on Saturday, May 3rd, 1941, to determine the championship of the Metropolitan League of New York City, the front page of the Brooklyn Daily Eagle was filled with news of the war in Europe, but there was no hint of what was to come on Sunday, December 7, 1941, at Pearl Harbor in Honolulu. 
     At the time, the U.S. Navy was patrolling at least 2,000 miles off the coast and within 1,500 miles of western British ports for the purpose of spotting Axis surface ships, submarines and aircraft. The Navy's orders was to report their location and maintain contact until British forces arrived. The Navy was under strict order not to fire unless it was necessary in order to avoid getting sunk. 
     In other news, back on February 2, 1941, 24-year-old Patsy Lasasso and his partner, Michael Gurlo robbed Louis Ozinsky, a laundry collector; they got 7 cents. They told Ozinsky that they thought he had a lot more money on him. He replied, "Not today. I make my next collection on March 8th. See you then; same time and place." 
     The brainless bandits kept the appointment and detectives concealed nearby as the result of Ozinsky's report of the first hold-up arrested them. It turned out that after the Ozinsky incident the two thieves had also robbed Frank Purpura, a barber, on February 8th. For his crimes, on May 3rd, 1941, Lasasso was sentenced to 15-30 years in Sing-Sing prison; his partner was still awaiting sentencing. 
     Buried on the back page of the Eagle was a story about how the previous year four Brooklyn police detectives were returning by train from Auburn prison with a prisoner who they wanted to question concerning the shooting of two police officers. 
     When the train pulled into Yonkers, the prisoner tried to escape and according to the article, the prisoner "was pumped full of .38 calibre bullets, one of which would be enough to rip a horse." The prisoner later died in the hospital and the four detectives were commended in a Brooklyn Police Department bulletin for foiling the escape. 
     About that Met league championship...it was determined in 1941, as usual, by the match in the final round between the Manhattan CC and the Marshall CC. Playing 18 boards, the Marshall team emerged victorious with a final score of 9.5-8.5. Having drawn one of their earlier matches (with North Jersey), the Marshall team had to beat the Manhattan team to win back the title. A drawn match would give the championship to the Manhattan team which was undefeated. 
     The upset of the match was Albert Pinkus' victory over Reuben Fine in what was the first game Fine had lost for a long time and after he had just scored an impressive win in the Marshall club championship. 

     At the conclusion of four hours of play the Marshall team was one point ahead but the games at boards 2, 6 and 11 were unfinished. 
     Frank Marshall at board 2, fought a grueling battle with Arnold Denker and emerged with a Rook and Bishop against Denker's Rook, Bishop and Pawn. Although Denker was a Pawn up the game was a sure draw. 
     On board 6, Herbert Seidman had blundered away a whole piece early in his game against State Champion Robert Willman, but fought back and reached a Rook and Pawn ending only a Pawn down. The two didn't adjourn and played on until Seidman finally succeeded in establishing a drawn position. 
     The remaining unfinished game between Irving Heitner and Geoffrey Mott-Smith was a different story. After he sacrificed the exchange, Mott-Smith failed to find the winning continuation and by adjournment even his drawing chances were in jeopardy and Heitner had excellent winning chances. That meant the result of the match depended upon this game. For Marshall to win the match and the championship Mott-Smith needed to salvage a draw. 
     The game was resumed eight days later and on May 11th after 40 more moves Mott-Smith managed to salvage the draw the game and so win the match for Marshall. 
     Here is Albert Pinkus' win by very precise play over Reuben Fine. As sometimes happened to Fine in domestic tournaments, he made a gross blunder in an even position. Over confidence maybe?

Make 'em sweat. Play Basman's Defense

 
     English IM Michael Basman (March 16, 1946) is a prolific writer who has made a lot of contributions to the field of openings. 
     What I like about Basman is that he is particularly known for playing bizarre openings in his own games. Stuff like the St. George Defense (1.e4 a6), the Grob (1.g4), the Creepy Crawly (a3, h3 followed by a quick c4) and the Basman Defense, aka the Borg Defense (1...g5). 
     Besides the Grob which I have played for years, I also like the Basman Defense and play both of them a lot on Chess Hotel. Of course, they both severely weaken the K-side, but the Basman more so because black is already a tempo behind. 
     According to Modern Chess Openings black is only somewhat worse, but that doesn't seem right! One source I looked at asserted that the data gives white a very high chance of winning (almost 59 percent), while black only has a 41 percent chance of winning. That doesn't seem right either because the drawing percentage is zero! 
     Whatever the percentages are I'm convinced that against average players Basman's Defense is not all that bad because they often seem to get totally bewildered when they face it. All in all, it's not a bad defense to keep in your back pocket. 
     The following wacky game is a good example of the kind of fun you can expect when you meet 1.e4 with 1...g5. A game that I liked (Komodo 14)

A Flurry of Tactics by Reshevsky

 
     The 1942 U.S. Championship was the most controversial ever. In January the USCF had canceled the tournament because the Japanese had bombed Pearl Harbor on Sunday morning, December 7, 1941, and the government had issued a call for an all-out struggle in the war. In an attempt to comply, the USCF stated that because our way of life was in great peril, it was not a propitious time for holding the championship. 
     Al Horowitz dissented in his magazine, Chess Review pointing out that Washington had encouraged the continuation of professional sports and that other nations at war, such as Great Britain, had continued holding tournaments. The USCF relented and the top players agreed (surprise!) to forego appearance fees and guarantees of prize money agreeing to play for modest prizes. 
     The lineup wasn't a very strong one with only seven real contenders: Reshevsky, Kashdan, Denker, Steiner, Pinkus, Horowitz and Seidman. The winner should have been Isaac Kashdan. 
     The tournament was a race between him and Reshevsky, but Kashdan got cheated out of the title. 
      In the 6th round tournament director, the infamous L. Walter Stephens, incorrectly forfeited Denker after Reshevsky supposedly exceeded the time limit...or did he? 
     Both players were in time trouble and it has often been reported that Reshevsky's flag fell when Denker made the drawing move and punched the clock. According to the report on the incident in Chess Review they "were using a battered old clock with no flag indicators." 
     Stephens, standing behind the clock, picked it up and turned it around so that the clocks were facing opposite sides and then, declaring that Denker had exceeded the time limit, ruled him to have forfeited. 
     When his mistake was pointed out, Stephens refused to change his decision. The spectators demonstrated their disapproval of Stephens' ruling with boos and jeers and Denker filed a protest because Reshevsky was not keeping score. It was all to no avail because his protest was disallowed! 
     Isaac Kashdan reported on the incident in Chess Review stating that Reshevsky defeated Denker in a drawn position when Denker overstepped the time limit and Stephans' ruling "(caused) a commotion and near riot." Kashdan wrote, "The spectators and officials all (got) a look at the clock which (was) carried about and handled by all and sundry. There (was) a wide divergence of opinion, but the referee (had) ruled and (was) later upheld by the tournament committee." 
     From beginning to end the tournament was a neck and neck race between Reshevsky and Kashdan. After nine rounds they were tied at 8.5 points apiece! Reshevsky had drawn with Matthew Green in the third round and Kashdan had drawn with Jacob Levin in the fourth. Their scores put them ahead of their closest competitors by two points. 
     The remaining rounds were a battle between the two. In the tenth round Reshevsky took the lead when Kashdan overlooked what was called a brilliant Queen sacrifice by Herman Steiner and lost. But, then in the next round Reshevsky could only draw against the last place finisher, Herman Halhbohm, a minor master from Chicago. 
     After finishing his last round game Kashdan had a 12.5-2.5 score. Reshevsky, at 12-3, adjourned his game against Horowitz who had outplayed him and was two Pawns up. But, thanks to opposite colored Bishops and a better placed King, Reshevsky had drawing chances. 
     Upon resumption Horowitz' 58th move allowed Reshevsky to draw and so tie with Kashdan. In the 14-game playoff Reshevsky took the lead after the fifth game and won the match +6 -2 =3. 
     The U.S. Women's Championship was held concurrently and, unlike the men's event, it was no contest. May Karff scored 8-0 and outdistanced the second placed finishers, Adele Belcher and Nancy Roos by two points. 
     I was going take a look at that Kashdan-Steiner game because the "brilliant Queen sacrifice" description caught my eye, but after looking at the game it turned out the Steiner only offered his Q in a won position and Kashdan didn't take it. In fact, Kashdan was forced to surrender his Q two moves later. 
     Probably the most brilliant game of the tournament was Reshevsky's win by a flurry of tactics over Herbert Seidman. Let's take look at it. 
     Reshevsky's style was often criticized because it was said he was lucky and that his play was boring. But, as they, good players are always lucky. 
     As for the boring part, back in 1940 in Meet the Master, Dr. Max Euwe wrote that Reshevsky liked boring positions and then went on to explain that many situations which other masters would abandon as won or drawn were analyzed more correctly by Reshevsky who often discovered numerous hidden possibilities.
     Reshevsky's rival, Dr. Reuben Fine, preferred to say that Reshevsky was "the tactician par excellence." Fine explained, "Regardless of the nature of the position, he is rarely prepared to accept any conventional judgment and he will exhaust all his resources before he admits that he is wrong." 
     Looked at from that viewpoint, Reshevsky's win in the following game was quite typical of his style. Herbert Seidman (1920-1995) was a Senior Master from New York City known for his swashbuckling style. He played several U.S. Championships and took the scalps of many notable players, including Benko, Bisguier, Donald Byrne, Denker, Lombardy, Mednis and Reshevsky. In the U.S. Open in 1974 he defeated the formidable Dutch GM Jan Timman on the black side of a Scandinavian Defense. A game that I liked (Komodo 14)

New York Met League Match 1954

     At the end of New York City Metropolitan League, two undefeated teams, the Marshall Chess Club Seniors and the Manhattan Chess Club, met at the Manhattan club in the seventh and last round on Saturday, May 22, 1954.
     The weather was partly cloudy with a high of 65 and a low of 45. The front page of the Brooklyn Daily Eagle had a story that was a prelude of what was to come. 
     Halfway around the world in what was then known as Indo-China, it was reported that Communist troops overwhelmed the French fortress at An Xa in the Red River delta and then struck northward toward Hanoi 40 miles away. 
     The outpost in Quang Nam Province fell after three weeks of bloody fighting when 800 Communist Vietminh regulars overcame the exhausted company of Vietnamese by sheer weight of numbers. 
     Just 11 years later, on October 3, 1965, 30 men from Company M, 3d Battalion, 9th Marine Regiment were walking across a rice paddy in eastern Quang Nam Province when rifle fire and mortar explosions erupted from three sides. The ambush was nearly perfect. About 200 Viet Cong had surrounded the Marines. Caught in the open with no cover they were pinned down. The firefight that resulted lasted for almost eight hours and 13 Marines were killed in one of the costliest days since the United States had entered the war. 
     When relief reached the patrol the firing suddenly ceased and the Viet Cong slipped away into the gathering night. The Marines rescued what was left of the patrol and retrieved the dead and wounded. The firefight had nearly annihilated the patrol and all of them had been wounded and nearly half were dead. 
     The dead were: 26-year-old 1st Lieutenant Adam E. Simpson, Jr., Staff Sergeant Roscoe Ammerman (age 37), Private First Class Robert W. Allen who was 2 days shy of his 18th birthday. Sergeant Nelton R. Bryant (age 26), Corporal Eugene L. Ellwood (age 19), Private First Class Louie G. Fritts (age 19), Private First Class Michael R. Fulk (age 18), Sergeant Paul Hamilton, Jr. (age 27), Corporal Larry D. Harvey (age 21), Private First Class Leon P. Lampley (age 20). Oddly, Lampley was from the same hometown (Hamilton, Ohio) as Corporal Ellwood. Private First Class Bernard J. Masny (age 19), Sergeant Reginald Nicolas (age 29) and Private First Class James Edward Thomas (age 19). Semper Fi, Marines!
     Back to the chess match. By mutual agreement, there were 12 players to a side for this match. The names for the first six for each side were shuffled and drawn to determine who played whom. By a happy coincidence, US Champion Larry Evans and former Champion Arnold Denker met. The lower six were similarly drawn. 
     At adjournment, Manhattan led by 4.5-3.5. In the play-offs, however, the match turned out one-sided and Manhattan won 8-4. 
     In the following game Simonson put up a fierce struggle, but he was unfortunate as the dubious opening variation he chose saddled him with a weaknesses which plagued him throughout all the phases of the game.

White's pressure on the d6-pawn often compels black to respond to Bxf6 with ...gxf6, rather than recapturing with a piece (e.g. the queen on d8) that also has to defend the d-pawn. This weakens black's K-side P-structure, but in return black gains the two Bs and a central Pawn majority.} Qa5 {Starting out as a QP opening it has now transposed and no doubt because of his unfamiliarity with the latest lines Simonson feared walking into a prepared variation and so chose the inferior text move deliberately.
