Planinc Loses Queen, Wins Game

Albin Planinc
    The names in this game probably won’t be familiar to today’s players, but they were very active in the 1960s and 1970s. Dragoljub Minic (1935-2005) of Yugoslavia was an IM who was made an Honorary Grandmaster in 1991. Minic was found dead by friends in his Novi Sad apartment on April 9, 2005, after failing to respond to phone and intercom calls for several days. Doctors determined that he died of a heart attack approximately four days earlier, on his 69th birthday. 
    Albin Planinc (1944 -2008) was a Slovenian GM who was a venturesome, romantic player that was committed to taking great risks to win. Known for extremely imaginative play, he was capable of spectacular results and often played brilliant attacking games, but his play was always too erratic to enable him to make it to the very top levels. 
     He was awarded the GM title in 1972, then became a chess trainer when the strain of playing tournament chess was contributing to his poor mental health. Planinc continued to suffer from severe depression for decades, spending the last years of his life at a mental institution in Ljubljana. In 1993, he changed his last name to Planinec. 
    The opening is the Archangelsk Variation which is one of the more aggressive, fighting variations against the Ruy Lopez. The variation was developed in the early sixties by players from the north Russian town of Archangelsk and was intensively analyzed by players from Lvov. The game features bold, imaginative play and explodes when Planinc is practically forced to surrender his Queen, but manages to create threats using his far advanced d-Pawn and when Minic soon went wrong it allowed Planinc a spectacular win.

Space, Time and Material

    
One of the first instructional books I read was The Middlegame in Chess by Eugene Znosko-Borovsky (1884–1954). Little known as a writer, Znosko-Borovsky was a Russian master and highly regarded author who was known for his instructional books. He had a knack for explaining things in an easy to understand way. In the book he discussed how to evaluate middlegame positions based on space, time and force (i.e. material). Another book that addresses these same elements, but also covers a lot more subjects, is Ludek Pachman’s The Opening Game in Chess. 
    These basic elements play a large part in the opening. Time, that is piece development and the gain or loss of a tempo, and the struggle for the center and the attempt to gain space to maneuver the pieces are, or should be, familiar. 
    The other element, material, can be hard to assess because the amount is important, but sometimes other factors must be considered. e.g. in some positions a Knight might be more valuable than a Rook. And, another example is in the opening when material may be sacrificed to gain time or space.
    Today’s game is a good illustration of the elements. The game was played in the Hastings tournament in 1895. This tournament was the strongest ever held up to that time. 
    Steinitz’ opponent was Curt von Bardeleben (1861-1924) of Germany. According to Chess metrics in 1895 he was one of the top ten best players in the world. On January 31, 1924, at the age of 62, after plunging from an apartment window in Berlin. Some sources say it was suicide, others an accident. 
    The suicide theory suggest it was triggered by financial troubles he experienced. He was supposedly living in povery at the time having lost his fortune during World War I. 
    Jacques Mieses and Bernhard Kagan, two of his contemporaries, believed it was accidental. In an obituary, Kagan suggested that Bardeleben suffered from severe arteriosclerosis and might have had a dizzy spell while leaning out an open window and lost his balance. Kagan’s theory is possible. Feeling dizzy, losing coordination have a difficult time walking and unexpectedly fall down are some of the symptoms of arteriosclerosis.
 

     In this game von Bardeleben avoids a lot of pitfalls by not taking a second gambit Pawn when it was offered at move 7. However, he was under some pressure after having taken the first gambit Pawn because Steinitz had more space and piece activity. von Bardeleben’s real mistake came when he played 16...c6 which made it impossible to complete his development even though the material was greatly reduced. Had he played 16...Kf7! it would have connected his Rooks and resulted in complete equality. This brings to mind the statement by one of the game's really great teachers, C.J.S. Purdy, who reminded his students that development is not really complete until the Rooks are connected.

Another Fine Win at New York 1948/49

Reuben Fine
    
A Chess Life article on the 1948/49 New York international tournament caught my attention because Fred Reinfeld labeled Arnold Denke’s 9th place finish with a +0 -5 =4 score as greatly disappointing. He then lambasted Denker saying that while Denker’s play was rich in (tactical) ideas, he lacked “staying power and a serious attitude. His play is fundamentally frivolous: he lacks the self-discipline to stick to a logical line of play and will always cast it aside for the gaudy bauble of a scintillating sacrifice which may or may not be sound.” 
     Harsh criticism! Fred Reinfeld was a very strong player, stronger than most people give him credit for, but he never accomplished as much as Denker did. Reinfeld also chastised Denker for having time trouble “again and again.” In this tournament the time limit was 40 moves in two hours. 
    A grumpy Reinfeld was also critical of the play of the then U.S. Champion Herman Steiner saying, “He is a happy-go-lucky player whose performances are extremely uneven. Aside from the fact that the time limit plagued him, his play was much too superficial to carry weight in such company.” 
    Reinfeld’s blathering about the course of the following Denker vs. Fine game was way off, but then he didn’t have an engine, so we can forgive him. That said, it was those very comments that caused me to ferret out the unpublished game and take a look at it! The game turned out to be a bit disappointing. It was boring up until the point where Denker’s rambunctious attempt to attack backfired and he lost quickly. But, since I bothered to look it up and run it through Fritz for analysis here it is.

Nice Guys Finish Fifth

    
In the last round of the New York International tournament of 1948/49 Reuben Fine offered Al Horowitz a draw on the thirteenth move. Horowitz, who was considered a kind and gentle person by his close chess colleagues, refused in order to preserve Miguel Najdorf's chances. Horowitz went on to lose and so the nice gut gesture cost him a share of the prize money. 
    Fine, at the time rated (on paper at least) as one of the workd’s top players, jas his fans (if he had any) worried that he wouldn’t be able to live up to his reputation. For this tournament, at least, they need not have worried. According to Chessmetric’s December 1948 rating list Najdorf was rated #2 in the world behind Botvinnik. Fine was ranked #11 and former World Champion Euwe was still doing pretty well being ranked #18. 
    This tournament was Najdorf’s first appearance in the United States and ieven though he finished second. Chess Review called it “an artistic fiasco.” In the early going it looked like he was going to run away with first place, but he had been lucky.
 
 
    In his game against Najdorf, Arnold Denker had achieved a winning position and Horowitz’ draw against him had been a lucky one. Horowitz was in bad time pressure and am excited Najdorf missed the win several times and got himself into a lost position, offered a draw, and a keyed-up Horowitz accepted. After that hair raising encounter Najdorf cooled off. A half point behind at the start of the sixth round, he played recklessly and lost to Fine. His last two games were lifeless draws.

Membership required losing a tournament game to her and the club membership included Dr. Max Euwe, Samuel Reshevsky, Edgar Colle, Lajos Steiner, Sultan Kahn, Sir George Thomas, F.D. Yates. Albert Becker and William Winter, all big names back in those days.   
    Vera Menhik Stevenson (February 16, 1906 – June 26, 1944) was born to English and Czech parents in Moscow. She was married to Rufus Henry Streatfeild Stevenson, who at one time served as secretary of the British Chess Federation, from 1937 until his death in 1943. She learned to play chess at the age of nine and, after her family settled in England in 1921, she began taking lessons from Geza Maroczy. 
    Her style was positional and she was also known for her endgame expertise. Chessmetric estimates her highest rating to have been 2535 in 1929m ranking her #52 in the world. The top players were Alekhine. Capablanca, Nimzovich, Bogoljubow and Euwe. 
    Menchik was Women's World Champion from 1927 until 1944, when a German V1 rocket destroyed her London residence, killing her, her mother and her younger sister Olga Menchik. Watch a Youtube video
    The virtually unknown Olga Menchik (1907-1944) was also born in Moscow. In January 1927, Vera won the London ladies championship, and Olga finished second. She finished fourth in the Women's World Championship at Warsaw in 1935, and tied for 17–20th in the sixth WWC at Stockholm in 1937. In 1938, she married a Briton named Clifford Glanville. 
    At London 1932, the prominent British Master Sir George Thomas (1881-1972, 91 years old) joined the Vera Menchik Club. Thomas was born near Istanbul, Turkey. He learned chess from his mother, Lady Edith Thomas, who won one of the first women's tournaments that was held in Hastings in 1895. He was the British Champion in1923 and 1934.
 

    In addition to chess, Thomas wass the most successful player ever in the All England Open Badminton Championships, considered the unofficial World Badminton Championships, with 21 titles from 1903 to 1928. Four of those titles were in men's singles, nine in men's doubles and eight in mixed doubles. In tennis, he reached the quarterfinals of the singles and the semifinals of the men's doubles at Wimbledon in 1911.

Benko Bashes Fischer

    
The 1962 Candidates Tournament in Curacao was a disappointment for Bobby Fischer; he finished fourth with a score of 14-13 behind Tigran Petrosian, Paul Keres and Efim Geller, but ahead of Viktor Korchoi, Pal Benko, Mikhail Tal and Miroskav Filip. 
    Fischer's poor result resulted in him howling about how the Soviet players colluded to prevent non-Soviets from winning. He alleged that the short draws Petrosian, Keres and Geller played against each other were prearranged. They were and his accusations resulted in FIDE changing the Candidates Tournament to a series of knockout matche.
    Fischer was also involved in a dispute involving Pal Benko and the use of their second, Arthur Bisguier. The USCF didn’t have the money to furnish noth players with a second, so they had to share Bisguier. 
    Benko and Bisguier showed up at Fuscher’s hotel room hopong he would assist in analyzing Benko;s adjourned game against Petrosian, but Fischer had a hissy fit and refused to let Bisguier help Benko, arguing that since he was in a better position in the tournament, his games should take priority. 
 The result was a physical altercation when Benko refused to leave tFischer’s room. Fischer filed a formal protest with tournament officials, claiming Benko hit him. The way I heard it told was that Benko slapped him.
    Fast forward to 1970. Benko gave his place in the 1970 Interzonal tournament to Fischer because Fischer was the best hope for winning the world championship. Benko had qualified from the U.S. Championship (Fischer did not participate), which was a zonal qualifier.
    Getting back to this Benko vs. Fischer game played in the first round at Curacao, Benko opined that losing this game “had a very negative effect on Fischer and in the next round against Geller he lost again...When (the tournament was over) his great performances (in other tournaments) were overshadowed...” 
 Benko opened with 1.g3 which is rarely seen in GM play, but he played it in every game until the round 23. Fischer had difficulty handling it and Benko got a space advantage, won a Pawn, and despite his usual time trouble, he managed to secure a winning advantage. In annotating the game I found Benko’s comments very enlightening.

A Most Remarkable Game?

`
In 1938, the U.S. faced economic difficulties with rising unemployment. President Roosevelt founded the National Foundation for Infantile Paralysis (known as the March of Dimes) to combat polio. As an elementary school student I remember filling collection cards with dimes. We would receive a card, collect dimes from family and friends and then return the filled card to the school and it could earn you a lapel pin. In those day the possibility of getting polio was a scary thing and the program helped fund the development of the successful Salk polio vaccine. 
    On June 24, 1938, a meteorite weighing over 990,000 pounds exploded about 12 miles above the earth near Chicora, Pennsylvania. It was felt for miles and injured a cow though it missed populated areas like Pittsburgh, averting a major catastrophe. The explosion's sound and light were described as a fireball, similar to thunder, and were initially mistaken for other events, like a powder magazine explosion. 
 The fact that the meteorite entered the atmosphere at a 30- degree angle which expended its energy. If it had entered the atmosphere at a nearly vertical trajectory, most of it would have survived the descent. The resultant impact would have caused major damage to Pittsburgh and the surrounding area. 
    In 1938, movies out of Hollywood offered with box office hits like Alexander's Ragtime Band (it generally traced the history of jazz music) and You Can't Take It With You (about a man from a family of rich snobs who becomes engaged to a woman from a good-natured, but eccentric family.) 
    The year saw the invention of practical, synthetic fabrics and board games like Monopoly. Games like backyard games, card games, and board games were popular ways for people to entertain themselves during the Great Depression. 
    A game was played in the 1938 Utah State Championship that Chess Review describes as, “One of the most remarkable played by American amateurs!” Was it remarkable as in notably or conspicuously unusual? You be the judge. One thing that is was however, was an example of when NOT to play the Classic Bishop Sacrifice, Bxh7+ and Ng5+.
     The Utah Chess Association has long existed in various forms, bu records are not generally available. The 1938 Utah Champion is not documented in tournament records. Fortunately, the July 1938 issue of Chess Review listed the results. The championship was won a 20-year old University of Utah student named Richard Durham who scored 7.5-1.5.  Others scores: 
 
        2-3) D.L. Morgan (Salt Lake City champion) 7.0-2.0 
        2-3) W. Taylor (the only player to defeat Durham_ 
        4) C. H. Stewart (Idaho champion) 5.5-3.5 
        5-6) Dittman 4.5-4.5 
        5-6)) O.W. Manney (Arizona and New Mexico champion) 
        7) L. N. Page (defending champion) 4.0-5.0 
        8) G. J. Moore 3.0-6.0 
        9) H. Davis 1.5-4/5 
        10) R. Kooyman 0.5-8.5.

More on the Alexandria Engine

    
In a previous post I noted that I had been experimenting with the Alexandria engine and noted that it might be useful for uncovering an opening surprise when preparing for over the board play. 
    The following game was recently played online and using Fritz, I tested Alexandria by letting it analyze the game at 15 seconds per move with the idea of then checking the analysis against Stockfish’s. 
    To my surprise, Alexandria suggested no improvements! What I ended up doing was analyzing the game with Stockfish and then going through it again with Alexandria running in orfer to compare the results. 
    Unlike other engines that will allow you to see multiple lines, Alexandria only shows its top choice and it only uses one core. Its evaluations in Centipawns seems considerably higher than Stockfish. 
     As mentioned previously, while Version 8 is obviously very strong based on its Computer Chess Rating List results, it no longer seems to be available. The version 5 that I have does not seem to be practical for analysis. While it may be able to discover some hidden possibilities in the opening, a better engine for that purpose is probably Berserk which is also highly rated on the CCLR rating list and can be downloaded from the same site as Alexandria HERE
     Last year I played two games against a 2300+ otb Master who is also an ICCF International Master because I wanted to test the highly aggressive Berserk to see if it could discover any opening innovations. It didn’t and once we got out of the opening I felt my positions were slipping a bit even though Berserk showed things were equal, It was then that I switched back to Stockdish and we played two uneventful draws.

Dr. Miroslav Filip Hoodwinks Tal

    
Miroslav Filip (1928 - 2009) was a Czech Grandmaster. He was born in Prague and like Ludek Pachman, he benefited from the occasional presence of the world champion Alexander Alekhine in Prague competitions during the early 1940s. However, it was not until the age of 25 that Filip began to make a serious mark on the postwar chess scene. 
    From 1955 to 1962, the 6 foot 9 inch tall Filip became a world force. During this period he twice achieved the arduous feat of qualifying for the Candidates Tournaments for the World Championship at Amsterdam in 1956 and again at Curacao in the Netherlands Antilles, 1962. Filip never was chess professional so his two appearances in these events are an impressive achievement. 
    After the Candidate tournaments Filip grew less enthusiastic about tournament play and was more concerned with avoiding defeat than in scoring wins. He also became more involved in journalism and serving as an arbiter. 
 

 
    The following game, mentioned in the previous post, was probably Filip’s best in the tournament. Tal was playing his usual sharp game and had established a significant advantage when he got hoodwinked. Filip’s sacrifice of the exchange caught Tal off guard and he played a few weak move before totally collapsing.

Engine Experiment

    
Labor Day was officially established as a national holiday in the United States on June 28, 1894, when President Grover Cleveland signed a law passed by Congress making the first Monday in September a legal holiday to honor American workers. The first Labor Day celebration, however, had already taken place in New York City on September 5, 1882, organized by the Central Labor Union. 
    Now that the long weekend (for those who are still working) is over) and things are back to normal I have been monkeying around analyzing a game Tal lost to Filip in 1962 that has turned out to be more complicated than expected, playing a bit online where I had one interesting game that I might publish and I have been looking at an engine named Alexandria. 
    While visiting the CCLR engine rating list I noticed the open source neural network engine Alexandria 8.0.0 64-bit 4CPU was ranked 7th only 28 points below Stockfish 17.1. 
     I was unable to locate a site where version 8 was available and while searching for it visited Chess Engine Diary on Facebook and found the link to download version 8. Clicking on it took me to a porn site! Quickly backing out and running my antivirus program turned up no threats. 
    What I did find was a safe download of an older (about two years) version, Alexandria 5.1.4 on an interesting site called CHESSENGERIA. On my laptop Alexandria version 5 was defeated in 4 minute blitz games by Stockfish by a score of +0 -4 =1, but I found something interesting in the process. The evaluation of Alexandria notes that it “does not wait for...unfavorable developments”, but is willing to take risks in an attempt to weasel out of an unfavorable situation. 
    As a test, I used a position from the previously mentioned Tal-Filip game because that’s exactly what Filip did. He was in a bad situation and took a risk and it worked. Specifically, I wanted to compare the two engines’ analysis of the position after Tal’s 24.gxf5 to see how they compared. 
 

    Both engines give white a winning advantage of about 3.5 Pawns after 24...Re7. However, I was excited to see that Alexandria initially looked at Filip’s sacrifice of the exchange (24...Rxe5) which it finally evaluated at about 6 Pawns in white’s favor compared to Stockfish’s 5 Pawns. As a result, the risk was too great and so Alexandria finally settled on 24...Re7 as preferred by Stockfish. 
    Obviously, Alexandria is weaker than Stockfish and so there is not much point in using it for analysis purposes after the fact. What it might be useful for is uncovering an opening surprise when preparing for over the board play.

The Famous Levitsky - Marshall Game

    
In the previous post mention was made of the fact that Rossolimo’s brilliant Queen sacrifice, which mimicked Marhall’s against Levitsky at Breslau in 1912, received scant attention. According to Andy Soltis in his book of Marshall’s best games, in his memoirs Marshall wrote that the spectators became "so excited" by the finish that they "showered me with gold pieces." Marshall added, "I have often been asked whether this really happened. The answer is… yes, that is what happened, literally!" 
    Soltis noted that in his original handwritten notes Marshall made no mention of the coin tossing incident, bur commented, "A purse was presented to me after this game." 
    Also from Soltis' book, according to Walter Korn, the Austro-Hungarian chess writer who is most famous for authoring Modern Chess Openings, that’s not the way he heard the story. 
    Korn wrote that when he was a young player in Prague witnesses to the game claimed that Alekhine and another friend of Levitsky's had bet on the game (presumably with Marshall) and when Levitsky resigned they tossed their bets on the board. 
 

    The game was played in the Congress of the German Chess Association. While Marshall;s performance was forgettable, his game against Lewitsky was not. Stepan Levitsky (1876-1924) was a Russian Master of considerable ability who passed away prematurely at the age of 47. Chess metrics estimates his highest ever rating to habe beem 2603 in 1913, placing him at #22 in the world.

Rossolimo's Most Brilliant Games

    
Most players beyond the beginner stage are familiar with the concept of control of the center and the idea that pieces must be developed quickly and actively. Pawns also play their part and in the opening Pawn moves can be good or bad. Pawn moves delay the development of the pieces can have dire consequences. 
 I occasionally play online and often see lower rated players wasting time with Pawn moves like a3, ...a6, h3 and ...h6 in the belief that they are preventing possible attacks by Bishops and Knights reaching b4 or b5 and g4 or g5. However, such Pawn moves should not be played unless there is a specific reason for doing so. 
 Most players are also familiar with the concept of the Classic Pawn Center (Pawns on d4 and e4) and the following game is a good example, plus the opening, the Giuoco Piano which is a favorite of many non-Masters, was used. 
    The Giuoco Piano was a favorite of GM Nicolas Rossolimo (1910-1975) who was born in Kiev in the Ukraine, but eventually made his way to New York City by way of Paris. 
    The game, which was awarded a Brilliancy Prize, was played in the 1967 Puerto Rico Open that was held in San Juan. Robert Byrne scored 6.5-0.5 to take first place and Bernard Zuckerman, who drew with Byrne and Dr. Erich Marchand, finish second with 6-1. The sixteen-year-old Puerto Rican Champion Julio Kaplan and Rossolimo headed a group with 5.5-1.5. 
    Besides being a good example of opening play, Rossolimo’s Queen sacrifice is reminiscent of the one Marshall played against Leviysky at Breslau in1912. See the game HERE. As far as I know, Rossolimo’s game received no mention in the tournament reports.
