Searching for Old Chess Publications

 
       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.

Reshevsky Butchers Bruckstein

    
Samuel Reshevsky (1911-1992) has always been one of my favorite players; the other was Mikhail Botvinnik (1911-1995). His 100 Selected Games had the cover worn off it from excessive use. I don't know what happened to the book as it got lost somewhere. I do have Mikhail Botvinnik by Andy Soltis though. 
    The same goes for my copy of Reshevsky's Best Games which I think was a republication of Reshevsky On Chess that was published by Chess Review in 1948. Rumor has it that the book was ghost written by Fred Reinfeld. At some point I managed to procure a copy of the book in Spanish...Reshevsky Frente al Tablero that was translated by Enrico Falcon that was published in Buenos Aires in 1954.
    When downloading the following game I discovered there was some confusion concerning it. A reader on the download site pointed out that the original source for the game was the American Chess Bulletin, but noted that the St. Louis Star's newspaper report on the simultaneous listed Reshevsky's opponents and Bruckstein was not one of them. Reshevsky's book doen't help. He simply said that it was played as "part of exhibitions held during my tour of various locations in the United States." 
    However, a check of the American Chess Bulletin clears up the problem. Reshevsky was on the road under the care of his manager and he paid two visits to the city. His game against Bruckstein was played on the second visit. In all, he played 40 games, scoring 38 wins and a loss with one game apparently unfinished. We will take a look at the game he lost in the next post. 
    After his visit a committee of St. Louis citizens made an offer, including special educational advantages for Reshevsky if his family would take up permanent residence in St. Louis. 
    Nothing is known of Reshevsky’s opponent, but I did locate a bit of information on one of those ancestry sites. Max Bruckstein, a baker by profession, was born in 1880, in the Russian Empire. He married Helena Bruckstein on October 27, 1903, in St. Louis, Missouri. They were the parents of at least one son and one daughter. He died in 1946, at the age of 66. In this game Bruckstein butchered the opening and Reshevsky dispacted him with deadly accurate play.

Elmer E. Southard

    
Elmer E. Southard (July 28,1876 0 February 7, 1920, 43 years old) was a neuropsychiatrist, neuropathologist, professor, author and chess player. He was born in Boston, Massachusetts and lived there most of his life. 
    Southard’s professional accomplishments were legion, but nor a lot is known of his chess. He was a member of two local chess clubs and was described in his New York Times obituary as "one of the foremost amateur chess players in America. He was able to play up to six blindfold games simultaneously. It was Southard who introduced what he called the Danvers Openign, but to day ot;s known by a few other names: 1.e4 e5 2.Qg5. The Danvers State Hospital was formerly a psychiatric hospital in Danvers, Massachusetts, 
    At the age of 43, Southard died of pneumonia in 1920 during a trip to New York City to deliver lectures to two medical societies. 
    After his death a study was done on his brain anf, a;sp, the brains of his parents. Ithe study was conducted to determine hereditary links in brain structure. His brain had a prominent frontal lobe, which was believed to be associated with his planning ability. 
    It was also noted that he had small olfactory tracts and that’s why he had difficulty detecting certain smells. It was a;so noted that the arteries at the base of his brain were small, but the significance of them was unclear. None of these features were apparent in his parents. 
    The report mentioned that during the last years of his life Southard experienced considerable mental discomfort and he sensed his impending death. As a result he felt pressure to complete his research tasks. 
    His opponent in the following game was Dr. Robert P. Elmer (1877-1951, 73 years old). He was bon in Bridgeport, New Jersey and passed away in Bryn Mawr, Pennsylvania. The game was played in the fourth annual intercollegiate tournament which was held at Harvard University Cambridge, Massachusetts. Southard went on to win the tournament the following two years. 
 

    The winner of the tournament was Arthur Ryder (1877-1938), a professor of Sanskrit at the University of California, Berkeley who became known best known for translating a number of Sanskrit works into English. He finished second to Southard in the event the following year.

Razzle-Dazzled by the Irish Gambit

    
There is a Chess Hotel in Paris that is located in one of the most prestigious areas of the city, close to the Opera and La Bourse – the Paris stock exchange. If you want to hang out there it will cost you somewhere around $300 a night. If you want to hang out at the other Chess Hotel, the one online, and play chess it’s free.
    When boredom sets in I sign in as a guest at Chess Hotel and play a few 10 minute games. I am not sure, but I think the Chess Hotel website is controlled from Stockholm, Sweden. 
    It’s a good site for a few casual games and you can expect to meet all kinds of opponents ranging from engine users to strong players to beginners. 
    There is a fair share of poor sports...players who get losing positions and then just leave the site, or worse yet, those who just let their time expire without moving. Occasionally you get an opponent who like to swear at you, or as happened to me a while back, a near beginner who quickly got a lost position and then began slinging accusations of engine use. Believe me, it didn't take an engine to beat him! It reminded me of the time at the chess club at Camp Lejeune, North Carolina when I beat some young kid and he said, "Where I come from I hardly ever lose." My reply, "Where I come from I hardly ever win."
    Then there was a recent opponent who asked if I spoke English and after finding out I did, asked where I was from. When he found out he said he was from the Ukraine and proceeded to tell me how much he hates Americans. All I can say is some people are amusing. 
    When playing these games my openings are all the dubious ones I can think of because they are fun to play and the results don’t mean anything. Upon seeing things like 1.h4, 1.g4 or with black 1.e4 d5 2.exd5 c6 3.dxc6 e5 (sort of a Danish Gambit Reversed) it’s surprising how careless some players get. The following game featuring the Irish Gambit (aka the Razzle-Dazzle or Chicago Gambit) is a case in point.

Morphy At His Worst

    
Yesterday dawned gray (in American English) or grey (in British English), but either way it was a dreary day as a huge winter storm brought cold and snow, or rain and chill, depending on your location. 
    After digging out, it was time to settle in and look at some chess games. The following caught my interest. In 1858, before Morphy left Paris he finally met an opponent who, while not his equal, was at least able to put up a fight. 
    The fact that Morphy got off to a bad start though wasn’t due to his opponents great play. According to Morphy’s secretary it was lack of sleep and fatique due to his having been enjoying Paris’ night life. 
     Daniel Harrwitz (1821-1884) was one of the stringest players of the day. He had a minus score against Morphy, but was one of a few who could occasionally beat him.  

    Harrwitz lived in England from 1849 and founded the British Chess Review. In 1856, he moved to Paris. In hos match against Mor[hy he won the first two games, but then Morphy got his act together and after the score was 5.5-2.5 in Morphy’s favor Harrwitz withdrew vlaomomg health problems. After that he retired to the Austro-Hungarian Empire.

An Old Masterpiece

    
I recently came across an old book edited by Fred Wilson titled Lesser Known Chess Masterpieces 1906-1915 which contains 165 games that appeared in the old Year Book of Chess. The book was published by Dover Publications in 1978. 
    Fred Wilson is still around and owns Fred Wilson Chess Books in New York City. He has authored a number of chess books and appears to have set some sort of record when, in 2017, at age 71, he finally elevated his rating over 2200 to claim the National Master title. Unless you’re in that age bracket it’s hard to appreciate the accomplishment! 
    The games are all exciting and some of the opening are out of date, but that’s part of their charm. Most of the games, as well as those who played them, have been long forgotten. 
    Today we will take a look at the first game in the book. It was won by Simon Alapin (1856-1923). He was born in Vilnius, Lithuania and later settled in St. Petersburg before finally moving on to Heidelberg, Germany. He has a number of opening variations named after him, most notably the Alapin Variation of the Sicilian (1.e4 c5 2.c3), which has become quite popular in recent times. Chess metrics estimates him to have been one of the world;s top 10 players in 1898. 
 His opponent was the Russian Pyotr Romanovsky (1892-1964) who won the Soviet Championship in 1923 and, jointly, 1927. According to Chessmetrics he was the 12th best player in the world six different time between 1925 and 1935. 
    During the Siege of Leningrad in winter of 1941–42, a rescue party reached Romanovsky’s home where they found him half conscious from starvation and the cold. The rest of his family had frozen to death. All their furniture had been used for firewood. 
    During the winter of the siege temperatures in Leningrad dropped to 40 degrees below zero (F). That winter was considered the coldest of the 20th century in Europe. People ate meager rations of bread and when food ran out, they resorted to eating things like wallpaper paste, leather and in some cases the bodies of the dead. 
    I remember the Andes flight disaster in 1972, where a plane carrying a Uruguayan amateur rugby team crashed in the remote Andes mountains. Only 16 of the 45 on board ultimately survived their 72-day ordeal. They survived by resorting to anthropophagy (eating human flesh). Of that practice, in a documentary one of the survivors stated, “If you had been there you would have done the same thing.” 
 
    After his recovery Romanovsky started a new family and continued to work to promote chess and train players. He was awarded the IM title in 1950 and the International Arbiter title in 1951. In 1954 he Soviets partitioned FIDE to award him the GM title, but lated withdrew it for political reasons that had nothing to do with Romanovsky.

Robert Byrne At His Best

    
In 1972, the U.S. saw bell bottom pants and platform shoes, and popular toys included the the Easy Bake Oven. In more recent times the oven was considered to be one of the most dangerous toys ever because children could get burned using it. It makes you wonder how children managed to survive playing with such horribly dangerous toys!? 
    A major film was The Godfather and on cable televidion HBO was launched becoming the first subscription cable service in the U.S.. The Volkswagen Beetle became the world's best-selling car by the end of the year. The year was dominated by the Match of the Century when Bobby Fischer defeated Boris Spassky to become the World Champio thus ending 24 years of Soviet dominance. It also generate an unprecedented worldwide interest in chess, particularly in the United States. 
 In San Antonio, Texas the Church's Chicken International was the strongest tournament held in the US since 1924. It ended in a three-way tie between Tigran Petrosian, Lajos Portisch and the rising star Anatoly Karpov. Mikhail Tal dominated the Soviet Championship, winning with a score of 15-6. 
    The 1972 United States Championship and Zonal Tournament, played in New York City, was a cliffhanger. The U.S. Championship was an exciting one. Going into the last round six players were still in the running, but Robert Byrne, Lubomir Kavalek and Samuel Reshevsky ended up sharing the title. Byrne qualified for the 1972 Interzonal in Leningras where he had the greatest success of his career, finishing in third place a half point behind Korchnoi and Karpov. He lost his first-round Candidates match to former world champion Boris Spassky by 1.5-4.5 in San Juan, Puerto Rico, in 1974.
 
 
    GM Robert Byrne (1928-2013), before becoming a professional player, was a university professor from Indianapolis, Indiana. I had the pleasure of meeting Byrne once and found him to be a perfect gentleman with a sense of humor. Reshevsky? Well, I once heard the infamous Norman T. Whitaker declare, “Reshevsky wouldn’t help anybody!”

Impressive Win by a Young Larry Evans

    
First, to US readers, enjoy your Thanksgiving tomorrow. I hope your weather is better than ours...winds that are half of hurricane force, freezing temperatures and snow. 
    Today’s post features a game by the loser in the last post, Larry Evans, that shows him in a better light. In the 1954/55 Rosenwald tournament held at the Marshall and Manhattan Chess Clubs there were mo surprises. 
    Reshevsky, who had 25 year’s experience and was the country’s top rated player at 2766 finished first as expected. Larry Evans (2620 amd Arthur Bisguier (2587) took the bext two spots. Donald Byrne (2587), James Sherwin (2404) and George Kramer (also rated 2404) were also rans. 
    At the time it was thought that Evans and Bisguier might, in the not too distant future, be, like Reshevsky and Fine had been, the top US players; they developed into very strong GMs, but mot that strong! 
 
 
 
    Evans had an even score in the first half, but them scored three wins and two draws in the second half. He barely edged out Bisguier who started s;ow;y, but then in the second half scored four wins (one over Reshevsky) and a draw (with Evans).
    Kramer’s horrible score could be attributed to his long absence from play against strong opposition. Larry Evans (1932-2010, 78 yearsd old_ was born in Manhattan, New York am achieved the GM title in 1957. After WWII George Kramer (1929-2024, 94 years old) was one of the most promising new players in the country. A chemist by profession, he remained an amateur, but a very strong one.

A Rare Bird

    
By the time of the 1958/59 US Championship Bobby Fischer had become a Grandmastyer and an international star. In this tournament it was thought he might face a sweious challenge from the former Hungarian Pal Benko who had been doing very well in European events. But, Benko had a mediocre performance and Fischer went undefeated to take his second title in a row. 
    The following game is from that event and it’s an interesting one that contains a mix of strategy and tactics. It’s a rare bird in that, at least in modern times, not many games between Grandmasters end in mate. 
    The players came out of the opening with equality, but on move 13, in an attempt to play aggressively, Reshevsky made a slightly inferior move that gave Evans good chances. Things were going well for Evans until move 23 when he made a tactical error that, according to Reshevsky, could only be attributed to a lack of positional judgment. He was quick to add that he wasn;t implying that Evans lacked positional judgment, but his troubles resulted from misjudging the position and sacrificing a Pawn on move 27. After that his, position deteriorated rapidly. In spite of his manly defense his position soon collapsed.
