Beating a Dead Elephant

 
    
The first time the Elephant Gambit (1.e4 e5 2.Nf3 d5) appeared in print was in the late 1600s. It’s considered unsound because black is unable to get any compensation for the sacrificed Pawn. It might be OK for Blitz games and amateurs, but at the GM level it’s probably best not to play it. The following game is proof. Lilienthal went really wrong on move 3 (!) and never had a chance. 
    The loser was the strong Soviet GM Andor Lilientha (1911-2010m 99 years old). He was born in Moscow to Hungarian parents and was taken to Hungary at the age of two, but emigrated to the Soviet Union in 1935. He retired in 1976, returned to Hungary and remained well liked and respected. 
    The winner was another strong GM, Isaac Boleslavsky (1919-1099, 57 years old). He learned to play chess at the age of nine, but it was not until after World War II that he really made a name for himself and become one of the top Soviet players. He died in Minsk after a fall on an icy sidewalk. He suffering a broken hip that got infected during his hospitalization. 
    The game was played in the 1941 Soviet championship which took place in Leningrad and Moscow. The winner was going to be the challenger for Alekhine's world title, but WWII put the kibosh on that plan. 
 

     Boleslavsky’s play was not only brilliant, it was perfect! The game was analyzed with the Fritz program and Stockfish at 30 seconds per move and Boleslavsky’s play was assigned an accuracy rating of 100% meaning that the engine could not improve on a single one of his moves. After analyzing hundreds of games I have never seen this happen.

Deep Position Analysis with Fritz

    
Sometimes you want a really deep analysis of a particular position and there are several ways of doing it. Years ago the program Aquarium introduce IDeA (Interactive Deep Analysis), a feature that was all the rage. 
    There was nothing wrong with the program and their customer support was outstanding, but I didn’t like the feature because the learning curve was too steep and I didn’t have the patience! 
    Fritz has something similar, but the disadvantage is that once you stop the analysis the program does not remember it and the next time you access the saved analysis you have to start over. IDeA picks up the project where it left off. 
    In a fit of boredom, I wanted to see see how Fritz' Deep Position Analysis, which I never use, compares to Infinite Analysis, so I did a DPA on a critical position from an old correspondence game of mine and gave the program 30 minutes, but the process took only about 15 minutes. 
    According to the manual the DPA function is very good for getting deep and detailed analysis of a critical position and it is especially useful for correspondence players and, I suppose, opening research. 
    You can determine how deep and broad the tree should be. Using DPA allows you to set time to analyze or the depth to which it should go. You set the number of Branches. i.e. how many alternative moves are given. You set the length of analyzed variations. And, you determines when a variation will be discarded. e.g. the value of 100 (one Pawn) means that moves that are a Pawn worse than the best move will not be investigated. 
    At the end of the DPA all the variations that have been generated are sorted and the strongest move becomes the main line. Here were the results.   
    . A game that I liked (Fritz 17)

    The bottom line (I think) is that there is little reason to bother with the Deep Position Analysis feature and simply use Infinite Analysis.

Capablanca Dodges a Bullet


    The 1931 New York Invitational was sponsored by the Manhattan Chess Club. Capablanca won with little difficulty although he did have a lost ending (surprise!) against Arthur Dake. Unfortunately for Dake, he started rushing his moves and refused to adjourn and eventually lost. 

    Capablanca also dodged a bullet in his game against Frank Marshall. The game appears in Harry Golombek’s book Capablanca’s Hundred Best Games of Chess that was published in 1946. I consider Golombek to have been a good writer, but he missed the mark in this game when he praised Capablanca's tactic at move 22 when, in fact, it should have lost. You can hardly blame Golombek for missing the refutation though! After all, both Marshall and Capablanca missed it, too!

FIDE’s First World Amateur Championship Match

Bogoljubow
    
Founded in 1924, FIDE soon started trying to organize the World Championship, but two years earlier Capablanca, the World Champion from 1921 to 1927, had set the conditions under which he was willing to play for the Championship. Those conditions were far beyond the resources of the fledgling FIDE. 
 Consequently, Alexander Rueb, FIDE’s president, then had the idea of creating a separate championship to be named the FIDE Championship. And so, in a letter sent to Max Euwe and Ewfin Bogoljubow he proposed that the winner of their match would become FIDE Champion of FIDE. 
    Their decision was based mainly on the fact that the 1928 World Amateur Championship that was held in Amsterdam had been won by Euwe. Also, at that time Bogoljubow was one of the top 3 or 4 best players in the world. 
    The match generated a lot if enthusiasm in Holland and Bogoljubow scored a narrow victory, scoring +3 -2 -5. Them after the match a wealthy sponsor finance a second short revenge match that was also won by Bogoljubow +2 -1 =7. 
    The following is game 4 of the first match is replete with imaginative and forceful play on Bogoljubow’s part. Queens were exchanged in the opening, but that didn’t cut down on the aggression shown by Bogoljubow. The tension mounted until ay the critical moment and Euwe went down the wrong path and was never able to recover

Bledow’s Queen Sacrifice at move 8

    Happy Birthday 
Dr. Ludwig Erdmann Bledow (July 27, 1795 - August 6, 1846).  He was a German master and organizer who was the co-founder of the Berlin Pleiades, a group of several German masters and in 1846, he founded the first German chess magazine, Schachzeitung der Berliner Schachgesellschaft. Later it wa renamed Deutsche Schachzeitung. 
    In those days some of the game’s moves and competition rules had not been universally agreed upon, For example, Bledow believed that a player should be allowed to have multiple Queens when promoting Pawns. He also argued in favour of the touch-move rule. 
 In 1848, about two years after Bledow’s death, a letter he had wtitten to Tassilo von der Lasa proposing that an international tournament should be organized was published. His idea was that the winner would be recognized as the world champion. In 1851, the surviving members of the Berlin Pleiades nominated Adolf Anderssen to represent Germany at the London 1851 tournament. As winner of the tournament Anderssen was widely recognized as the world's strongest player. 
    It’s difficult to say exactly how strong Bledow was, but in the mid-1800s he defeated some of the best players around in match play, including the 27-year old Adolf Anderssen by either 5-0 or 4.5-0.5, depending on the source. According to Chessnetrics there is no rating for Bledow and Anderssen’d estimated rating in 1848, three years after the match) was only in the mif-2400s, considerably below his 2600+ rating in the early 1850s. 
Dr. Ludwig Blewow

    As for his playing style, Bledow was described as preferring closed positions and not a "heroic" player. His surviving games support that claim, but the following game featuring a Queen sacrifice on move 8 is a pleasing exception. 
    His opponent was Paul Rudolph von Bilgur (1815-1840, 24 years old) a German master and theoretician. von Bilguer, who was a lieutenant in the Prussian army, resigned his commission and devoted his time to chess. 
    He was considered to be the most brilliant of the 'Pleiades' players. He is best known today as the co-author of the Handbuch des Schachspiels. He died at age 24, probably of tuberculosis, before finishing the Handbuch, but the work was completed by his friend Tassilo und der Lasa, who gave primary credit to Bilguer. The book was a reference book, particularly om openings. 
    While this game is far from perfectly played, Bledow;s Queen sacrifice will leave you gasping.

Seidman Sets a Snare

    
The Intercollegiate Chess League has a long history dating back to leagues like the Quadrangular Intercollegiate league (Harvard, Yale, Columbia and Princeton) in 1892. In 899, thr Triangular Intercollegiate League (Cornell, Brown, and the University of Pennsylvania) established their own triangular league. These laid the foundation and the Pan American Intercollegiate Team Chess Championship, established in 1946, became a major annual event. 
    Today’s game was played in 1938, in a collegiate league in New York City made up of two teams from the Central College of New York, Brooklyn College, two teams from New York University and Yeshiva College. 
    In 1938, the title and custody of the Harold M. Phillips trophy was won on a 4-0 forfeit by a team from C.C.N.Y when the team from Yeshiva College failed to appear at the Manhattan Chess Club for the last match. This was on a Sunday after Saturday’s match had been rescheduled to accommodate the Yeshiva players who could not play o the Sabbath. 
    The Tournament Director, Harold Sussman, who was also the newly elected president of the league, gave the Yeshiva team until noon to appear and when the didn’t they were forfeited. The winning C.C.N.Y. tam consisted of Jack Soudakoff, Sava Jacobson, Milton Finkelstein and Samuel Rubin. 
 
 
    The game's winner, Herbert Seidman (1920-1995) was a Senior Master (rated over 2400) who was born in New York City. At his peak, he was ranked among the top ten players in the country. Seidman played in eight U.S. Championships between 1940 and 1968. 
 His obituary informs us that Jack Soudakoff was born in Russian and on Novmber 19, 2005, at the age of 87, he peacefully passed away surrounded by his beloved wife Bea, sons David and Alan and a future daughter-in-law Diane. Soudakoff was a edicated family man, WWII vet, longtime New York Subway systems analyst. 
    In the early middlegame Seidman had a modest advantage when, at move 20 instead of playing the obvious move, he laid a snare and Soudakoff got caught.

Gelfand’s Anti-Masterpiece

    
The 2012 World Championship natch between the defending champion Viswanathan Anand and challenger Boris Gelfand was held in Moscow. The prize fund was approximately 2.5 million dollars. It was foe 12 games. In case of a tie, first rapid games, then blitz games, and finally an Armageddon game if needed, would br played. 
    After the first six games the match was tied after six fairly short draws. Gelfand won game 7, but the next day Anand won game 8 when Gelfand managed to get his own Queen trapped in a miniature that is the shortest decisive game in World Championship history. It’s today’s featured game. 
    Then after four draws, the match headed into overtime. Anand was famous for his prowess in rapid and scored +1 -0 =3 in the rapid games to retain his title.play,
    The day before this game Gelfnd had produced a strategic masterpiece by Gelfand and it left some profits predicting that Anand’s days as World Champion were numbered, but they turned out to be false prophets when Gelfand produced this anti-masterpiece that lasted only 17 moves and 110 minutes.

A Rook Offer Black Couldn’t Accept or Refuse

 
    
In 1965, people were seeing were seeing changes in music, fashion and television. The British Invasion continued with groups like The Beatles and The Rolling Stones growing in popularity, Fashion saw the miniskirt and television offered a mix of wholesome family sitcoms and superhero like Batman. 
    The chess scene was highlighted by the Candidates Matches, a series of knockout matches to determine the challenger for the World Championship. The players were Spassky, Keres, Geller, Smyslov, Tal, Portisch, Larsen and Ivkov. Spassky won by defeating Keres, Geller and Tal. 
    Bobby Fischer didn’t participate because of his decision not to play in the 1964 Amsterdam Interzonal, the qualifying event. The disgruntled Fischer had previously accused Soviet players of collusion in the 1962 Candidates Tournament, an 8-player event where Fischer had finished 4eeth behind Petrosian (the winner) and Keres and Geller (tied). His accusations were well founded. 
    As a result, FIDE changed to the knockout matches, but, being the snot face he was, Fischer wasn’t satisfied. He still didn’t like the format and demanded specific playing conditions. 
 The Soviet Championship was won by Leonid Stein and veteran Soviet and renowned endgame composer Vitaly Chekhove passed away. 
    Fischer did play in the 1965 US Championship and won it even though he lost to Robert Byrne and Samuel Reshevsjy and was held to a draw by William Addison. He still finished a point ahead of Byrne and Reshevsky who were tied for second; Addison was 4th. 
 Up in Canada the veteran GM Dan Yanofsky of Winnipeg won the Canadian Championship over a strong 12-man field in Vancouver. There were several interesting games, including this one in which Duncan Suttles (born in 1945) defeated Joseph Kalteneck. 
 

    Suttles was born in San Francisco and his family bed to Canada when he was 8 years old. He was awarded the GM title in 1972 and retired from chess shortly thereafter to work on stock market analysis. Suttles was known for his unorthodox treatment of Hypermodern openings. In this game he conducts a vigorous attack straight out of the opening and finishes with a nifty Rook offer that could neither be accepted nor declined.

A Nice Finish by Carlos Guimard

  
 In 1938, tensions in Europe were escalating and growing Nazi aggression dominated world events. In the U.S. things were heavily influenced by the Great Depression and the looming threat of war. 
    In pop culture radio programs like the comedy Amos 'n' Andy, soap operas and sporting events were popular. Hollywood movies, including musicals and gangster pictures, provided entertainment Also, comic book, like Superman, were beginning to appear. 
    It was the year Orson Welles' War of the Worlds was broadcast and it caused widespread panic as some listeners believed the alien invasion was real. 
    In South America there was a a complex web of political, economic, and social shifts, largely influenced by events in Europe and the looming threat of World War II. 
    In Uruguay the situation was no different. General elections were held, resulting in the subsequent presidency of Alfredo Baldomir, a soldier and architect who served as President of Uruguay from 1938 to 1943. 
    Montevideo was the scene for the eighth South American Championship (Torneo Sudamericano) that took place in March. Alekhine was undefeated and finished 1.5 points ahead of Carlos Guimard. The other players were mostly known only in South America. The event was actually held in an elegant seaside resort Carrasco, one of the most expensive neighborhoods in Montevideo. 
    The featured game today has a nice finish. The winner was Carlos Guimard (1913-1998, 85 years old) of Argentina. He was awarded the GM title in 1960 and was he was Argentine champion in 1937, 1938 and 1941.
 

    His opponent was an Argentine National Master. Bensadon played aggressively, jis N on d5 cancelled out Guimard’s two Bs as both sides attacked their opponent’s King. The, right when things were looking drawish, Bensadon struck a snag when he miscalculated the strength of his passed e-Pawn and sacrificed his B in order to Queen it, but Guimard blocked the P and was left a piece up.

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.

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.
