Reshevsky Owned the e-file

    
The 1972 Chess Olympiad was held in Nice, France and saw the Soviet Union (Karpov, Korchnoi, Spassly, Petrosian, Tal and Kuzmin) took forst, finishing ahead of Yugoslavia (Gligoric, Ljubojevic, Ivkov, Planinc, Velimirovic and Parma.) The United States (Kavakek, Robert Byrne, Browne, Reshevsjy, Lombardu and Tarjan) finished third. 
    In the following game from the US vs. Sweden match in the Final A group the dominant factor was Reshevsky’s control of the e-file. Playing black, Reshevsky opened with the Benoni Defense which morphed into a King's Indian. 
    Udderfeldt failed to get anything out of the opening and Reshevsky hit on an idea on move 14 that he said seemed to surprise Udderfeldt who then made what Reshevsky called a “peculiar reply.” 
    Reshevsky gained control of the e-file and the game was practically over as the activity of his pieces kept increasing until his opponent was reduced to complete passivity. 
    It was a fine demonstration of putting the squeeze on an opponent, but a careful examination shows that it wasn’t the positional rout Reshevsky’s notes suggested. Udderfeldt missed some better defenses, but the game demonstrates the difficulty of defending a position with no real hope of counterplay. All that said, I consider the game was still a positional masterpiece by Reshevsky.
    Dan Uddenfeldt (born in 1951),is a Swedish master who was one of the leading players in Sweden in the 1970s when he participated in several international junior championships.

Bb2 {Another less than optimal decision. Udderfeldt wants to exchange as many pieces as possible in order to ease the pressure, but this allows Reshevsky to maintain the N on e4 and, as a result his advantage becomes very real.

Engine Analysis Then and Now

    When b
rowsing some of my old server games I came across the following very difficult game that was played on a site where engine use was allowed. When it was played in 2011, Rybka was the strongest engine, but it was later disqualified from the World Computer Chess Championship and stripped of all titles for plagiarism. 
    That meant Houdini was next in line as the top engine, but Rybka’s disqualification opened up opportunities for other engines like Stockfish to rise in prominence. Fritz was also a well-known engine in 2011, but it was generally considered weaker than Rybka and Houdini. Overall, by this time engines had become significantly stronger than human players with the best engines exceeding 3000 Elo. 
 In those days I only used the free engines and there were several strong free and open-source engines available. Stockfish was one of the most widely used. Houdini 1.5a was another extremely strong engine as was Rybka 2.3.2a. Critter, Gull, Protector and Crafty were also very strong free engines. 
    Many of these engines could be used with free graphical user interfaces such as Arena and Scid, but I was using Fritz 12. It was released in November of 2009. I don't remember the cost, but I found the program in a long defunct office supply store whose name I have forgotten, but not the price. I bought the CD for $20 which was a fraction of the price from the USCF. It was my go-to program until I replaced it with Fritz 17 in 2021. It's still on my laptop and I actually use it to conduct Shootout analysis because it works better for that than the newer Fritz programs. 
    When playing the following game I used several different free engines and on occasion felt they were suggesting less than optimal moves. In my old post-mortem analysis it was very difficult for me to determine what the best moves were, but my feeling was that black missed several chances to draw.
    Black’s trouble seemed to stem from the decision at move 52 to trade his two R’s for my Q and a P. Despite the engine evaluations giving white a nearly 3 Pawn advantage, my gut feeling was that by keeping the R’s on he would have made it much more difficult for me to squeeze out a win. 
    All that is moot because today it’s clear that he was already dead lost at move 52 and he had a bad position for many moves before that. It was interesting to analyze the game using today’s Stockfish and comparing it to the old free Rybka engine.

Fritz 20

 
    
First, let me say I have no financial interest in this product. As most readers are aware, I have been a fan of the Fritz program for years and not too long ago upgraded to Fritz 19 from Fritz 17. 
    There was not too much difference between the two for my purposes because I do not play against the program for fun and any idea about using it for improvement is out of the question. 
     According to reviews some users had some bug issues with Fritz 19, but I have not run into a single problem, at least not with the feature I use. 
    Now Fritz 20 is available (download from the USCF costs $77). The first thing I noticed is that the user interface has been redesigned. The new design is supposed to be “modern” and visually aesthetic. I don't like it, but that’s probably because it’s not what I am used to after all these years. They have also changed the 3D boards, but I never use them so for me it’s a moot point. 
    The major changes are in the area of playing for fun. They have added three modes for you to play against: Hypermodern, Robot and VIP.  In the Hypermodern mode the program uses flank openings. In the Configurable mode you can adjust various characteristics of the opponents. Most intriguing is the VIP mode that allows you to play against opponents like Fischer, Tal, Karpov, Capablanca and Lasker. These opponents play with the style of the player and use their opening repertoires. Watch this Youtube video
 
Conclusion:
    For Bloggers looking to publish games, average players looking to improve or just have fun, Fritz 20 is a fantastic program that is well worth $77. 
    If, like me, you are no longer looking to improve or you prefer meeting real live opponents online or you just want the basics like publishing games, analyzing, playing over games or using basic database functions then an earlier version, if you can fine one, will suit you just fine. If, on yhr other hand, you are looking for a program that is just plain fun to tinker with then you can;t beat Fritz 20.

A Solid Performance by Tal

    
Former World Champion Mikhail Tal (1936-1992, 55 years old) was noted for his brilliant sacrifices which were often base on intuitive thinking and his ability to calculate variations. 
    The following game shows another side of Tal’s play; there is no flashy tactics, subtle positional play or brilliant endgame play...just a rock solid performance. It shouldn’t be surprising that Tal could play something other than tactical chess because no player is going to become world champion with a one sided style. The intuitive sacrifices he was famous for were a personal preference. 
    In this game that was played in World Student Team Championship that was held in Uppsala, Sweden, in April 1956, Tal play was nothing flashy, just solid chess. 
    The Soviet team won the tournament with Hungary taking second place. The Soviet team won convincingly, notably defeating their main rivals, Yugoslavia, in the early rounds. Yugoslavia and Bulgaria tied for third. The United States team finished eighth. 
    Tal’s opponent was Borislav Ivkov (1933-2022, 88 years old). He was born in Belgrade, Yugoslavia and was awarded the GM title in 1955. Ivkov won the Yugoslav Championship in 1958 (tie), 1963 (tie) and 1972.

Najdorf Spits the Hook

    
In the following game Najdorf played the opening poorly, got a bad position, then got lucky when Rellstab missed the best move and completely collapsed. 
    For some players this game might reinforce the “never resign” philosophy. I play occasionally on Chess Hotel and often run into poor sports (that’s the kindest way I can think of to describe them, but other words come to mind) who, when they are badly lost will not move and let their time expire even if it means sitting there for several minutes, or rather than resig, they just leave the game. 
    Almost as bad are those who play on to the bitter end no matter how much material they are down. Sometimes that is justified if your opponent is very short of time and he may not be able to mate before his time expires. It’s an ugly way to win, but time limits are a part of the game. 
    One reason for not resigning a bad position though might be because you are playing a much weaker opponent who might be prone to making a blunder that allows you to salvage the game. That’s what happened to Najdorf here. 
    That’s not to imply that Ludwig Rellstan (Senior) (1904-1988) was a weak player!. Far from it. In his day (the late 1930’s and 1940’s) Chessmereics estimates his rating to have been near 2600 which put hime in the world’s top 25 or so players. Rellstab won the German Championship in 1942 and was awarded the International Master title in 1950. He was also an International Arbiter. His son, a Jr., was born in 1935 and his last FIDE activity was in 2001 when he was rated in the 2100 -2200 range. 
 

    When this game was played Najdorf was one of the top players in the world, at least in the top ten, so it’s natural that he wasn’t going to resign a bad, but not lost, position. The position was complicated and Rellstab had a wide choice of possible moves and he chose the wrong one and Najdorf got away.

A Seesaw Battle

    
My knowledge of players only goes back to Siegnert Tarrasch because I had Fred Reinfeld’s excellent book on Tarrasch’s best games. Steinitz, Staunton and Morphy are familiar names, of course, but not their games. 
    I confess to having no knowledge of the players of today’s game. The loser was Hyacinthe Boncourt (1765? - 1840), who was one of the leading players in France between 1820 and 1840, but not much is known about his life. Even the date of his birth is uncertain. 
    Boncourt was a contemporary of Philidor, but the two never played because the latter hademigrated to England and although Boncourt traveled around Europe, but he never visited London. He was a civil servant, and chess was mostly a hobby for him. 
    Pierre de Saint-Amant (1800-1872) was a regular player at the Cafe de la Regence and studied under Alexandre Deschapelles and Schlumberger. He was the editor of the chess periodical Le Palamede. Whilst visiting England in 1843 he lost a casual match to John Cochrane (+4 -6 =1) and defeated Howard Staunton (+3 -2 =1) in a casual match. Later u 1843, he lost a formal match to Staunton (+1 -6 =4). 
    Note: I came across this game in an old chess book that was published in 1952. The book and the author will remain anonymous because while the games themselves are interesting, the annotations are atrocious. Still, the games was a tremendous seesaw fight.

Corzo - Capablanca Match of 1901

    
In 1901, the 13-year ols prodigy Jose Capablanca played an exhibition match against Juan Corzo (1873-1941). 
    Corzo was born in Madrid and emigrated to Cuba in 1887 and won the Cuban championship five times (in 1898, 1902, 1907, 1912, and 1918). He is best remembered though for having lost the match against Capablanca.  
    Today’s game is ftom that match and it appears in Fred Reinfeld’s old nook, Attack and Counterattack in Chess. The old book was one of his “pot boilers”, in which he illustrates basic strategic principles with illustrative game. It’s annoying that he did not give players’ names, the event or the date. They are just labeled White and Black. 
    It’s a decent book with mostly verbal explanations. Of course, like all old books there are quite a few mistake in analysis, but the games themselves are interesting. I was able to identify this game because it was referenced in the tactical analysis performed by the Fritz program. 
    Reinfld used the game as an example of how to play against gambits, claiming that knowing how “is one of the most important qualifications for playing the black pieces skillfully.” Reinfeld ststed that “in order to succeed against a gambit, you must keep two valuable principles in mind. They are 1) the initiative is much more important than a material advantage and 2) the extra material can be used as a means of seizing the initiative yourself, often by returning it. Returning the extra material works because the opponent needs time to get it back and you can use that extra move or two to your advantage. 

    Capablanca’s game against Corzo is fascinating because of the way that he handled Corzo’s adventurous Hamppe-Allgaier Gambit which can lead to some real fireworks.

B.H. Wood Clubs Winter

    
The 1948 British Chess Championship was held in London ot turned out to be the last time the championship was contested as a round robin tournament. It was won by Reginald J. Broadbent. The Ladies' Championship was won by Edith Price at the age of 76, making her the oldest player ever to win a national championship. 
     Reginald Broadbent 1906-1988, 82 years old) was born in Durban, South Africa. He won scored many local successes in the 30’ and 40s. 
    The winner of today’s game, Baruch H. Wood (1909-1980, 79 years old) was born in Sheffield, England. He founded CHESS magazine in 1935 and was its editor until 1988, when it was sold to Pergamon Press. Wood served an an Arbiter for FIDE, a correspondent for the Daily Telegraph, and wrote a weekly column for Illustrated London News from 1949 to 1979. He co-founded the Sutton Coldfield Chess Club. His best playing years were in the 40’s and 50’s. His son and daughter are both strong players.
 
  
    The colorful William Winter (1897-1955, 58 years old), a man with a fondness for drink, was born in Medstead, England. FIDE awarded him the IM title at its inception in 1950. He was the nephew of Sir James M. Barrie, the creator of Peter Pan. 
    Winter won the British Open in 1934 and the British Championship in 1935 and 1936. A chess journalist by profession Wint authored a few chess books. At the outbreak of World War One he left college to serve in the Army. After the war he returned to his studies at Cambridge. The rumor goes that while there he came under the influence of an older woman and left the university and hisjob so he could air his Socialistic views. As a result, in 1921, Winter, an active member of the Communist Party, was sentenced to six months in prison for his seditious speeches.

Bernard Parham and the Matrix System

 
    
Born in 1946, Bernard Parham passed away on June 19, 2024 at the age of 77 in Lafayette, Indiana which is near Indianapolis. He was a National Master and the Indiana champion in 1967.
     
    He is best remembered as the inventor if the Matrix System, a method of analyzing a position.  The system views the board as a Cartesian plane. A Cartesian plane is a two dimensional plane defined by two perpendicular lines. the horizontal x-axis and the vertical y-axis. These axes form a grid system that allows for the precise location of any point. 
    Param’s system uses geometric patterns and vectors to analyze piece movement and attacking routes, especially towards the enemy King. It assigns point values to pieces based on their geometric capabilities that sometimes differs from their traditional values (e,g, traditionally a Rook equals 5 Pawns). The matrix provides a visual representation of attacking and defensive moves which serve as an aid to strategic decision making. 
    Confused? Intrigued? You will want to check out Chess Drum’s great article about Parham and his system HERE
    What’s the best way to meet 1.e4 e5 2.Qh5? Here is the result of 30 minute’s analysis by Stockfish which has been incorporated into an actual GM game. As you can see, 2.Qh5 is not a bad move and there is no refutation. In fact, the top three lines result in equality.

Marshall Surprises Mlotkowski

    
In 1915, World War I (1914-1918) limited international play, but there was still some activity. There was some activity in the United States...it wasn’t until April 2, 1917, that President Woodrow Wilson went before a joint session of Congress and requested a declaration of war against Germany. 
    A major tournament in New York was won by Capablanca ahead of Marshall. There followed by Oscar Chajes and Abraham Kupchik (tied). Edward Lasker and Jacob Bernstein (tied) and Einar Michelsen. It was also the year the Marshall Chess Divan (later the Marshall Chess Club was established. 
    In 1915, Marshall was active, giving simultaneous exhibitions a;; across the country including the following echibition game. Stach Mlotkowski (1881- 1943, 62 years old) born in Clifton Heights, Pennsylvania ajd died in Gloucester City, New Jersey. In 1904, he won theWestern Chess Association championship and in 1923, he ties for first with Norman Whitaker in the Western Chess Association championship, held in San Francisco. He wwas the California State Championship om 1923

Euwe Trashes Tartakower

    
The book was first published in English in 1953 and it’s been in my library for decades, but I have never read it. It’s Euwe’s Judgment and Planning In Chess. 
    An Amazon review says Euwe examines positions “from the point where the opening stage has come to an end and he describes the characteristics of the position. He explains why one side stands better and gives practical advice.” 
    Except for readers too lazy to learn Descriptive Notation, reviewers on Amazon give it good reviews, but I don’t like it. To me, Euwe’s writing is dry and boring. Naturally those of us who go over the games with engines will find errors in his analysis. That’s the case with all these old books. You can still learn from them because you are learning patterns and ideas. Besides, the games are usually interesting because they illustrate a point of some kind. 
 
 
    While browsing the book the other day I noticed the following game and after examining it more closely it turned out to be pretty interesting. Euwe played the opening poorly and Tartakower got an excellent position, but then got sidetracked by defending against a not very dangerous attack by Euwe. In trying to defend against the “attack” Tartakower weakened his own position and ended up with a lost one. Euwe’s conduct of the concluding attack was not perfect, but it was good enough.

Helms – Frere, an Exciting Slugfest

    
The name Hermann Helms (1870-1963, 93 years old), the Dean of American Chess, is fairly well known as the long time chess columnist for the Brooklyn Daily Eagle which carried his column from 1895 to 1955. He also served as editor of the American Chess Bulletin from 1904 until his death in 1963. 
    The little known Walter Frere (1874-1943, 69 years old) was a strong New York City amateur. His father had helped organize the First American Chess Congress of 1857 that was won by Paul Morphy. Ferer had been wanting to meet Helms in a match because when the last club junior championship had been held Frerer had been ill and unable to participate; hence, his desire to meet Helms in a match. 
    In October of 1893 one was finally arranged. Helms was the junior champion of the Brooklyn C. C. and Frere was the youngest player in the club. Frere had performed well the previous year. having defeated one of the club’s strongest players in a match. He had also finished third in a New York state handicap tournament. 
    The match started on September 19, 1893, and the winner was to be the first to win five games, draws not counting. With the score tied 4-4 the match was extended and the 6-6 result stood.. 
    The games were sharp and curiously several were quite short! Ferer lost the 2nd game in 18 moves, the 4th in 25 moves and the 7th in 29 moves. Helms lost game 9 in 13 moves, game 10 in 15 moves and game 13 in 22 moves! With the exception of the first game where the opening was a Scotch Game, all the games were either a Ruy Lopez or an Evans Gambit. Here is the exciting 7th game.
