A Fine Mini Loss


    
In 1937, Reuben Fine played in a number of European tournaments: Hastings, Warsaw, Moscow, Leningrad, Ostend, Kemeri, the Stockholm Olympiad and Semmering/Baden.
    According to Google AI, a tournament took place in Orebro, Sweden that year, the Nordic Chess Championship, which was won by the Swedish master Erik Lundin. Naturally, Fine did not participate, but he did give a simul there in which the following game was played. It’s a short, sharp tactical display won by his opponent.
    Tactics are crucial because they are short-term, forcing moves that capture pieces, deliver mate or gain a decisive advantage. Tactical patterns (or motifs) and mating patterns can be learned. Today there are a lot of books on tactics, but the one I learnrd from was The Art of Checkmate by Renaud & Kahn. You can read C.J.S. Purdy’s review of the book HERE
    Today programs and websites offer a wealth of possibilities for tactical training. The only problem is that in the training positions you know a tactic is lurking in the position. In your own games you don’t and that’s the problem! In casual Internet games I see a lot of players who evidently think they are playing tactical chess when they just willy-nilly sacrifice a piece without a tactical motif being present,  Those are not sacrifices...they are blunders.
     In the following miniature Fine played in a simul in Orebro in 1937, he played 11.Qb3, voluntarily walking into a pin on his N, he immediately got into serious trouble and his opponent took advantage of it in grand fashion.

Rhoda Bowles

 
    
The biography of Rhoda Bowles (1861-1931) appears in an excellent article by Batgirl on chess,dom HERE
    It’s hard to say how strong she really was, but in the following game her Accuracy Rating (i.e. how closely her moved matched Stockfish) was a whopping 85% which is considerably higher that most GMs achieve. 
    Her opponent was Frideswide (Fannie) Rowland (née Beechey (1845-1919) who was married to the Irish player Thomas Rowland (1850-1929). She was born in Gallway, Ireland and passed away in Bray, a coastal town on Ireland’s east coast.

Nezhmetdinov’s Flight of Fancy

    
From time to time I like to pull out Super Nezh: Rashid Nezhmetdinov, Chess Assassin by Alex Pishkin and play through a few of his games. 
    Nezhmetdinov was an early version of Tal...his combinations were fantastic, if not always entirely sound. Every time I play over his games I get to thinking I could play like that, but, of course I can’t. 
    The following game was played against Oleg Chernikov (1936 – 2015), an International Arbiter and the 2000 World Senior Champion. It was played in a Russian team championship at Rostov-On Don in 1962. 
    After Chernikov played 11...Bf6 a position was reached that had long been known to be drawn and so after making it, Chernikov went for a stroll thinking Nezhmetdinov would take a quick draw. But, Nezhmetdinov sunk into deep thought and everyone wondered what he could be thinking about. Finally, after 45 minutes a youngster rushed up to Chernikov and informed him that Nezhmetdinov had sacrificed his Queen. Nezhmetdinov’s Queen sacrifice only netted him two pieces, but he hoped to attack the weakened dark squares around black’s King.
    Immediately after the game it was thought black had a draw at best. Subsequent analysis reached the conclusion that the chances should be about equal if black plays 14...d5 instead of Chernikov’s 14...Re8. 
    However, since then it’s been discovered that black has several reasonable moves. While the engine evaluations after 14.Nc3 lead one to believe that the chances are even, practical results strongly favor black. 
    In the end, Nezhmetdinov didn’t succeed in overturning theory, but what does that matter? The depth of his plan and his flight of fancy are worth more than reams of engine analysis.

Potpourri

    
Now that the last few hectic days have passed things are starting to settle down. Christmas day put the quietus on chess activity although I did run a 5-minute tournament using the strongest engines in my arsenal. Clearly, Stockfish is the best, but the other engines can serve a purpose for strong OTB players who are looking for more human-like play in the search for opening innovations. The poor result of Lc0 is probably due to the fact that it requires more powerful hardware than I possess. 

    Isaias Pleci (1907-1979) was of Argentine was awarded the IM title in 1965 and was the Argentine Champion in 1929-30. He is little known, but fared very well in South American events in the 1930s and Chess metrics estimates his highest ever rating ti have bee 2582 in 1940 making him the 44th best player in the world. 
    Pleci won the individual bronze medal at the Stockholm 1937 Olympiad and the gold medal at the 1939 Buenos Aires Olympiad 
    His opponent in the following game played in the 1939 Olympiad was Gunnar Fried,amm (1909-1i44, 34 years old) of Estonia. He played on several occasions in Estonian championships and was a member of the Estonian Olympic temam several times. 
    Friedemann played for Estonia in the following Chess Olympiads. According to Chess metrics his highest rating was 2536 in 1941 ranking him #80 in the world. He died in the German Army on the Eastern front. 
    This game is the first game in Alekhine’s book 107 Great Chess Battles,; the games date from 1939 to 1943. The book gets a lot of negative reviews on Amazon and while it feels like an Alekhine potboiler, I like it simply because it has a lot of great games and not all were played by Alekhine.

Tal vs, Botvinnik

Mikhai; Ta;
    
One of the most exciting World Championship matches that I remember was the 1960 Tal vs, Botvinnik match. How would the staid, scientific Botvinnik do against the “Magician from Riga”, Mikhail Tal with his wild and sometimes unsound sacrifices Botvinnikd didn’t do well at all, but in the rematch the following year he turned the tables and won easily. 
    In their very first game Tal’s success was well deserved, but it wasn’t much of a fight. Botvinnik adopts one of his pet lines which is now known ti be questionable and his 11th move worsened the situation. Then for no obvious reason Botvinnik gave away a Pawn after which Tal demonstrated flawless technique.

Petrov’s Immortal Game

    
Such tactics as we see in the following game are likely to be considered crude by today’s strong players, but they were considered charming in the 1800s. Today most of us amateurs still find then charming, I think. 
    The idea of readily surrendering the Queen in order to hound the hostile King with the other pieces isn’t new, but Petrov's sacrifice was one of the earliest examples we have. What’s more, Stockfish suggested no improvements on his play. 
    Alexander Petrov (1794-1867) was a Russian player, composer and writer. He was born into a noble family and is usually remembered as the first great Russian master. From 1804, he lived in St. Petersburg. He established himself as the best Russian player at the age of 15 and remained so for over half a century. 
    He was the author of the first chess handbook in Russian. He also analyzed with Carl Jaenisch the opening that later became known as the Petrov Defense. From 1840. he lived in Warsaw (then in the Russian Empire), where he successfully played against the top Warsaw masters which included Alexander Hoffmann (1798-1855). 
    During the January Uprising (1863–64), he left Warsaw for Vienna and Paris. He died in Warsaw in 1867, and was buried there.

Fischer’s Last American Tournament

    
Bobby Fischer's last game was the 30th game of his 1992 rematch against Boris Spassky who resigned on his 27th move. I am not 100% positive, but I believe Fischer’s last America tournament was a double round rapid tournament at the Manhattan Chess Club in August of 1971. He won it with the incredible score of 21.5-0.5; he got nicked for a draw by Walter Shipman. 
    At the time, Fischer had just returned from winning candidates matches against Mark Taimanov and Bent Larsen. His match against Larsen, played in Denver, Colorado, had just concluded and Fischer, himself, called the club and suggested they arranged a 5-minute double round -robin invitational tournament and he would participate/ 
    Fischer wasn't known for playing in such events although he had played in one in Herceg -Novi, Yugoslavia, where he won easily against top level competition. In this tournament everybody was certain Fischer would win and the question was, would he make a perfect score? He had some close calls, but the only real danger came in his games against Andrew Soltis and Walter Shipman. 
    Against Soltis, who at the time lacked an international title, Fischer had a Rook and some Pawns against a Queen and Pawns. For young reader who aren’t familiar with pre-digital age chess clocks, they had little flags that the minute hand raised and the flag dropped at 12. With both flags hanging and the players moving at lightening speed, Soltis blundered into a lost position. He could have played on and possibly won on time, but Soltis is a class act and so he resigned. 
    Against Walter Shipman, Fischer tried hard to to win a drawn Rook and Pawn endgame, Fischer blundered away his Rook but his connected, passed Pawns enabled him to secure the draw. 
 
 
    In the following game Fischer crushed GM Robert Byrne. On the March 1971 USCF rating list Fischer was #1 at 2771 and Byrne was ranked #7 at 2527. Note that ratings are a reflection of results, not strength although it’s obvious that the strongest players will have the best results. Ratings across decades do not compare to each other. For example, on the latest USCF rating list Fabiano Caruana is #1 at 2876 and there are 3 other players rated over 2800. Today a rating in the 2500s will only get you ranked below 35th place. A game that I liked (Fritz 17)

Marshall vs. Pillsbury, a Titanic Struggle

    
By1906, when a King’s Gambit Accepted theme tournament was held in Vienna the enthusiasm for romantic gambit play had all but disappeared. In an attempt to revive interest, the Vienna Chess Club sponsored a King's Gambit tournament. 
    With the financial support of Albert Rothschild, an Austrian banker, and Leopold Trebitsch, an Austrian industrialist and chess patron, the Vienna Chess Club invited ten masters who played a double-round event. 
    The positional players (Schlechter, Maroczy and Teichmann) found it tough going; the wild tactical positions resulting from the King’s Gambit were anathema to them! 
 
     Thee Russian Chigorin, known as King of the Gambiteers, was in his element as was Marshall. He got lucky in the following game, a titanic struggle, against Pillsbury. This tournament turned out to be Pillsbury’s last European tournament. He died of syphilis in Philadelphia in 1906. The first effective cure for the disease came in 1910, but it was an arsenic-based compound that was toxic and hard to use; the real and safe cure, penicillin, began its widespread use in the 1940s.

Fine Beats Botvinnik

    
Reuben Fine (1914-1993, 73 years old) is mot, or perhaps never was, greatly appreciated as a player. He grew up in New York City and learned to play chess at the age of eight. 
    After winning several strong tournaments in the U.S. he then made a name for himself in international tournaments. He played on three Olympiad teams from 1933 to 1937, winning one gold and one silver individual medal. In 
    1937 he tied with Paul Keres for first at Margate, and at the AVRO tournament in 1938, he again finished tied for first with Keres. Then came World War II and he was employed by the Navy to estimate where enemy submarines might surface. These estimates were essentially educated guesses and often highly inaccurate.
    After World War II, Fine was invited to the World Championship tournament in 1948, but declined because he was working on his Ph.D. in psycholgy and he expressed dissatisfaction with FIDE's organization coupled with a distrust of thr Russian players thinking they would cheat bu helping each other. After that he pretty much faded from view. 
    Mikhail Botvinnik (1011-1995, 83 years old) was a different story. He learned the game early and progressed rapidly, winning the first of six USSR Championships in 1931; the others came in 1933, 1939, 1944, 1945 and 1952. 
    With the death of Alexander Alekhine in 1946, FIDE took control of the World Championship and invited six players to take part and Botvinnik won it. In 1957 Smyslov defeated Botvinnik in a World Championship match, but lost the return match the following year. Then in 1960, he lost to Mikhail Tal, won the rematch in 1961. He lost the title for the last time to Tigran Petrosian in 1963.
 

    In November of1938, a Dutch radio company AVRO organized and sponsored what was up to that time the strongest tournament ever held. Fine finished tied forfirst with Paul Keres who was declared the winner as a result of a better tiebreak score.

       Sunday posts are rare, but after the Alberta Clipper went through this neck of the woods last night and most of the city is moving at a crawl, it's a good time to check out the Hathi site.
     HathiTrust was founded in 2008 as a not-for-profit collaborative of academic and research libraries now preserving 19+ million digitized items. They offer access to the extent allowed by U.S. and international copyright laws. 
    If you sign on HERE and search for "chess' a lot of stuff comes up and a lot of scrolling will be required, but you can find old publications on chess problems or old copies of the British Chess Magazine or if you get really lucky, something like Smyslov’s Best Games
    Some other title you might find are Chess News Jan-Nay 1916 or a selection of games played in the international tournament at Bradford, England in 1888. 
    Most of this material won't find anywhere else and it is entertaining browsing. Of course, you must be able to read Descriptive Notation.

Don’t Scratch That Itch!

  
    
Not too long ago I got the urge to try my luck again at correspondence play. My last try was a year ago when I played a two game match against a player who is both an OTB IM and ICCF IM. 
    The goal was to test the Berserk engine which I had read was sometimes able to uncover hidden opening resources that might not be found by other engines. It didn’t find any and when we reached the early middlegame it seemed like my position in both games was starting to deteriorate a bit, so I switched back to Stockfish and drew both games. 
    I nearly entered an event that would have required me to play 10 games, but got to thinking that was too many. A lot of players who win top level correspondence tournaments these days find repeating the task too exhausting and they often don’t opt for a repeat performance. I’m not a top level player, but do I really want to put in that kind of effort? The answer is, “No!” and in any case my old laptop which is held together with clamps and duct tape just isn’t packing the gear for such play. 
    These days an important thing in correspondence play is opening preparation. The goal is to find a line that looks good on a cursory engine analysis, but when you go deeper it’s flawed. That takes hours (or days!) of analysis. 
    You also have to use different engines because each has its own strengths and weaknesses. Plus you must be able to guide the engine into lines that it might not prioritize on its own. Engines sometimes misjudge complex positions, especially endings. (I wouldn’t know, but that’s what the good correspondence players say). It’s those critical junctures a human has to recognize. The bottom line is that merely copying an engine's top move will likely lead to a draw or a loss against a strong, engine-assisted opponent. I have neither the gumption nor the skill to do all that. Hence, I avoided temptation. Here’s the way we played correspondence chess in the old days.

Fine’s Preposterous Opening

    
Reuben Fine (1914-1993) was a formidable player with a solid style. Arnold Denker compared him to Bobby Fischer because both were active positional players who possessed a universal style and were able to win in a variety of ways.
    Fine always aimed for precision without regard for where it lead tactically, positionally or into the ending. Tatrtakower observed that Fine, like Capablaca, was often able to make something out of nothing in his games. Denker even went so far as to claim that Fine was better than Reshevsky because he had a better understanding of the game. According to Denker, Reshevsky had the better record only because Fine lacked the tenacity and singleness of mind that Reshevsky had.
    Today Fine is probably remembered more for writing Basic Chess Endings than anything else. It's hardly entertaining reading because it's like a text book on a boring college subject. It focuses on endings that occur most frequently and offers tried-and-tested rules. Over the years mistakes in analysis were found, but the value of the book has not diminished and a great deal can be learned from it.
    Before he became one of the world's best players, in his college days the teenage Fine sometimes played some pretty bizarre openings as the following game show. The game was played in the 1931/32 Intercollegiate Championship that was won by City College of New York; Fine played board 1. 
    Even when playing an irregular opening the objective must be based on sound opening principles. So, after the move 1.f3 against Rappaport, Fine did not neglect the center. When his opponent failed to take advantage of the opportunity to gain space with 3...d4 Fine was able to gain control of the center himself.

King Hunt by Feigins

    
Movsas Feigins (or Feigin) was born in what was at the time the Russian Empire, but is now Daugavpils, Latvia. 
    He was a prominent Jewish Latvian master duting the 1930s. He was the Latvian Champion in 1932 and competing in several strong international tournaments before World War II. Between 1930 and 1939 Feigin played for Latvia in five official Olympiads and one unofficial one.
    Chessmetrics estimates his highest ever rating to have been 2581 in 1941 ranking him #49 in the world. Some other players close to his ratings were Soviet GM Grigory Levenfish and American Masters Albert Pinkus and Arnold Denker. Botvinnik was top rated at 2786. 
    In September 1939, when World War II began, Feigins was competing in the Olympiad in Buenos Aires, Argentina. Like many other participants, he chose to stay in Argentina permanently. He remained in South America, living for a time in Paraguay before returning to Buenos Aires, where he died in poverty in 1950.

Reshevsky Caught in Boden’s Mate

    As promised in the previous post this is the one game a young Sammy Reshevsky lost in a 1921 simultaneous display in St, Louis, Missouri. The game is interesting because Reshevsky got caught in Boden’s Mate. It's a handy pattern to keep in mind though it rarely happens. I can remember pulling it off in an online game only once.
