++1.    Machgielis (Max) Euwe

Machgielis (Max) Euwe (May 20, 1901 - November 26, 1981) was a
Dutch chess Grandmaster, mathematician, and author. He was the
fifth player to become World Chess Champion (1935-1937). Euwe also
served as President of FIDE, the World Chess Federation, from 1970
to 1978.

++1.A   Early years

Euwe was born in Watergraafsmeer, near Amsterdam. He studied
mathematics at the University of Amsterdam, earning his doctorate
in 1926, and taught mathematics, first in Rotterdam, and later at
a girls' Lyceum in Amsterdam. He published a mathematical analysis
of the game of chess from an intuitionistic point of view, in which
he showed, using the Thue-Morse sequence, that the then-official
rules did not exclude the possibility of infinite games.

++1.B   Early career

Euwe won every Dutch chess championship that he participated in
from 1921 until 1952, and additionally won the title in 1955 - his
12 titles are still a record. The only other winners during this
period were Salo Landau in 1936, when Euwe, then world champion,
did not compete, and Jan Hein Donner in 1954. He became the world
amateur chess champion in 1928, at The Hague, with a score of
12/15.

Euwe had a young family and could only play competitive chess
during school vacations, so his opportunities for international
chess competition at the top level were limited. But he performed
well in the few tournaments and matches for which he could find
time from the early 1920s to the mid 1930s. Fine comments, "Euwe's
main international successes came in the form of narrow defeats" -
but these were in matches against the world's best: Alekhine
(1926), Capablanca (1931) and Spielmann (1935); and Euwe drew a
match with Flohr in 1932. His playing strength gradually increased,
so that by 1932 he and Flohr were regarded as Alekhine's most
credible challengers.

At Zurich 1934, Euwe finished second, behind only World Champion
Alexander Alekhine, and he defeated Alekhine in their game.
Alekhine was in an eight-year stretch, from 1927-35, where he lost
only six games in tournament play.

++1.C   World Champion

On December 15, 1935 after 30 games played in 13 different cities
around The Netherlands over a period of 80 days, Euwe defeated
Alekhine by 15.5-14.5, becoming the fifth World Chess Champion.
Alekhine quickly went two games ahead, but from game 13 onwards
Euwe won twice as many games as Alekhine. His title gave a huge
boost to chess in The Netherlands. This was also the first world
championship match in which the players had seconds to help them
with analysis during adjournments.

Euwe's win was a major upset--he reportedly had believed that
beating Alekhine was unlikely - and is sometimes attributed to
Alekhine's alcoholism. But Salo Flohr, who was helping Euwe during
the match, thought over-confidence was more of a problem than
alcohol for Alekhine in this match, and Alekhine himself said he
would win easily. Former World Champions Vasily Smyslov, Boris
Spassky, Anatoly Karpov and Garry Kasparov analyzed the match for
their own benefit and concluded that Euwe deserved to win and that
the standard of play was worthy of a world
championship. Vladimir Kramnik, ex-champion and still a strong
contender, said that Euwe won the 1935 match on merit and that the
result was not affected by Alekhine's drinking before or during the
match.

Euwe's performances in the great tournaments of Nottingham 1936 and
the 1938 AVRO tournament indicate he was a worthy champion, even if
he was not as dominant as the earlier champions. Reuben Fine wrote,
"In the two years before the return match, Euwe's strength
increased. Although he never enjoyed the supremacy over his rivals
that his predecessors had, he had no superiors in this period."

Euwe lost the title to Alekhine in a rematch in 1937, also played
in The Netherlands, by the lopsided margin of 15.5-9.5. Alekhine
had given up alcohol to prepare for the rematch, although he would
start drinking again later. Alekhine got back to the sort of form
he had shown from 1927-1935, when he dominated chess. The match was
a real contest initially, but Euwe's play collapsed near the end
and he lost four of the last five games. Fine, who was Euwe's
second in this match, attributed the collapse to nervous tension,
possibly aggravated by Euwe's attempts to maintain a calm
appearance.

The two world title matches against Alekhine represent the heart of
Euwe's career. Altogether, the two played 86 competitive games, and
Alekhine had a +28 -20 =38 lead, according to chessgames.com. Many
of Alekhine's wins came early in their series; he was nine years
older, and had more experience during that time. Then in the return
match, Alekhine won by six points. So, during the period 1925-1935,
the two were very closely matched.

++1.D   Later career

Euwe finished equal fourth with Alekhine and Reshevsky in the AVRO
tournament of 1938 in The Netherlands, which featured the world's
top eight players and was an attempt to decide who should challenge
Alekhine for the world championship. Euwe also had a major
organizational role in the event.

He played a match with Paul Keres in The Netherlands in 1939-40,
losing 6.5-7.5.

After Alekhine's death in 1946, Euwe was considered by some to have
a moral right to the position of world champion, based at least
partially on his clear second place finish in the great tournament
at Groningen in 1946, behind Mikhail Botvinnik. But Euwe consented
to participate in a five-player tournament to select the new
champion, the World Chess Championship 1948. However at 47, Euwe
was significantly older than the other players, and well past his
best. He finished last.

His final major tournament was the Candidates' Tournament in
Zurich, 1953, in which he finished next to last.

He played for The Netherlands in a total of seven Chess Olympiads,
from 1927 to 1962, a 35-year-span, always on first board. He scored
10.5/15 at London 1927, 9.5/13 at Stockholm 1937 for a bronze
medal, 8/12 at Dubrovnik 1950, 7.5/13 at Amsterdam 1954, 8.5/11 at
Munich 1958 for a silver medal at age 57, 6.5/16 at Leipzig 1960,
and finally 4/7 at Varna 1962. His aggregate was 54.5/87 for 62.6
per cent.

In 1957 Euwe played a short match against 14-year-old future world
champion Bobby Fischer, winning one game and drawing the other. His
lifetime score against Fischer was one win, one loss, and one draw.

Euwe won a total of 102 first prizes in tournaments during his
career. While it is true that many of those were local and were not
very strong, the total is very impressive, considering that Euwe
was never a true professional player.

++1.E   FIDE President
From 1970 (when he was 69 years old) until 1978, he was president
of the FIDE. As president Euwe usually did what he considered
morally right rather than what was politically expedient. On
several occasions this brought him into conflict with the Soviet
Chess Federation, which thought it had the right to call the shots
because it contributed a very large share of FIDE's budget and
Soviet players dominated the world rankings - in effect they
treated chess as an extension of the Cold War. These conflicts
included:
*       The events leading up to Bobby Fischer's participation in
        the World Chess Championship 1972 match against Spassky,
        which led to Fischer's becoming the first non-Soviet
        champion since World War II. Euwe thought it important for
        the health and reputation of the game that Fischer should
        have the opportunity to challenge for the title as soon as
        possible and interpreted the rules very flexibly to enable
        Fischer to play in the 1971 Candidates Tournament.
*       The defection of grandmaster Gennadi Sosonko in 1972. The
        Soviets demanded that Sosonko should be treated as an
        "unperson", excluded from competitive chess, television or
        any other event that might be evidence of his defection.
        Euwe refused, and no Soviet players took part in the 1974
        Wijk aan Zee tournament in The Netherlands because Sosonko
        was playing in it.
*       In 1976 world championship contender Viktor Korchnoi sought
        political asylum in The Netherlands. In a discussion a few
        days earlier Euwe told Korchnoi, "...of course you will
        retain all your rights ..." and later opposed Soviet
        efforts to prevent Korchnoi from challenging for Anatoly
        Karpov's title in 1978.
*       Later in 1976 Euwe supported FIDE's decision to hold the
        1976 Chess Olympiad in Israel, which the Soviet Union did
        not recognize as a country. The Central Committee of
        Communist Party of the Soviet Union then started plotting
        to depose Euwe as president of FIDE.

Of course Euwe lost some of the battles with the Soviets. For
example in 1973 he accepted the Soviets' demand that Bent Larsen
and Robert Huebner, the two strongest non-Soviet contenders
(Fischer was now champion), should play in the Leningrad Interzonal
tournament rather than the weaker one in Petrspolis. Unsurprisingly
Larsen and Huebner were eliminated from the competition for the
World Championship because Korchnoi and Karpov took the first 2
places at Leningrad. Some commentators have also questioned whether
Euwe did as much as he could have to prevent Fischer from
forfeiting his world title in 1975.

Despite the turbulence of the period most assessments of Euwe's
performance as president of FIDE are sympathetic:
*       Spassky, who had nominated Euwe for the job: "He should
        certainly not have disqualified Fischer, and he should have
        been a little tougher with the Soviets.... you get a pile
        of complicated problems. But Euwe, of course, was the man
        for the job."
*       Karpov said Euwe was a very good FIDE President, although
        he did commit one very serious error, rapidly extending the
        membership of FIDE to many small third-world countries.
        "But neither he nor I could have foreseen what this would
        lead to. ... This led not only to the inflation of the
        grandmaster title, but also to the leadership vacuum at the
        head of the world of chess."
*       Garry Kasparov was blunter: "... unfortunately, he could
        not foresee the dangers flowing from a FIDE practically
        under Soviet dominance."
*       Korchnoi regarded Euwe as the last honorable president of
        FIDE.
*       Yuri Averbakh, who was a Soviet chess official as well as
        a grandmaster: "... he always sought to understand the
        opposing point of view ... Such behavior was in sharp
        contrast to the behavior of the Soviet delegation leaders
        ... Max Euwe was, without a doubt, the best President FIDE
        ever had."

He died in 1981, age 80, of a heart attack. Revered around the
chess world for his many contributions, he had travelled
extensively while FIDE President, bringing many new members into
the organization.

++1.F   Assessment of Euwe's chess

Euwe was noted for his logical approach and for his knowledge of
the openings, in which he made major contributions to chess
theory. Paradoxically his two title matches with Alexander Alekhine
were displays of tactical ferocity from both sides. But the
comments by Kmoch and Alekhine (below) may explain this: Euwe
"strode confidently into some extraordinarily complex variations"
if he thought logic was on his side; and he was extremely good at
calculating these variations. On the other hand he "often lacked
the stamina to pull himself out of bad positions".

Alekhine was allegedly more frank in his Russian-language articles
than in those he wrote in English, French or German. In his Russian
articles he often described Euwe as lacking in originality and in
the mental toughness required of a world champion. Gennadi Sosonko
thought Euwe's modesty was a handicap in top-class chess (although
Euwe was well aware of how much stronger he was than "ordinary"
grandmasters).

Vladimir Kramnik also says Euwe anticipated Botvinnik's emphasis on
technical preparation, and Euwe was usually in good shape
physically because he was a keen sportsman.

++1.G   Chess books by Euwe

Euwe wrote over 70 chess books, far more than any other World
Champion; some of the best-known are The Road to Chess Mastery,
Judgement and Planning in Chess, The Logical Approach to Chess, and
Strategy and Tactics in Chess Play. Former Soviet grandmaster
Gennadi Sosonko used Euwe's Practical Chess Lessons (Practische
Schaaklessen) as a textbook when teaching in the Leningrad House of
Pioneers, and considers it "one of the best chess books ever".
Fischer World Champion, an account of the 1972 World Chess
Championship match, co-authored by Euwe with Jan Timman, was
written in 1972 but not published in English until 2002.

++1.H   Other interesting accounts

In Amsterdam there is a Max Euwe Plein (square) (near the
Leidseplein) with a large chess set and statue, where the 'Max Euwe
Stichting' is located in a former jailhouse. It has a Max Euwe
museum and a large collection of chess books.

His granddaughter, Esmee Lammers, has written a children's book
called Lang Leve de Koningin (Long live the Queen), which is
popular among the youth. It is a fairytale about a young girl who
learns to play chess and at the same time finds her father. Lammers
filmed the story in 1995.

++1.J   Quotations

*       "Strategy requires thought; tactics requires observation."
        - Max Euwe
*       "Does the general public, do even our friends the critics
        realize that Euwe virtually never made an unsound
        combination? He may, of course, occasionally fail to take
        account of an opponent's combination, but when he has the
        initiative in a tactical operation his calculation is
        impeccable." - Alexander Alekhine
*       "If Richard Reti was interested only in the exceptions to
        positional rules, then Max Euwe believed perhaps a little
        too much in their immutability." - Alexander Alekhine
*       "He is logic personified, a genius of law and order. One
        would hardly call him an attacking player, yet he strides
        confidently into some extraordinarily complex variations."
        - Hans Kmoch
*       "Euwe can only breathe freely when he is smothered in
        work." - Hans Kmoch
*       "Euwe resting would not be Euwe. His star is work, work,
        and more work. Work is his entertainment, his strength and

*       "There's something wrong with that man. He's too normal." -

++2.    Richard Reti

Richard Reti (May 28, 1889 - June 6, 1929) was an ethnic Jewish,
Austrian-Hungarian, later Czechoslovakian chess player, chess
author, and composer of endgame studies. He was born in Pezinok
which at the time was in the Hungarian part of Austria-Hungary,
where his father worked as a physician in the service of the
Austrian military. His older brother Rudolph Reti was a noted
pianist, musical theorist, and composer.

++2.A   Biography

Reti came to Vienna to study mathematics at Vienna
University. One of the top players in the world during the 1910s
and 1920s, he began his career as a fiercely combinative classical
player, favoring openings such as the King's Gambit (1. e4 e5 2.
f4). However, after the end of the First World War, his playing
style underwent a radical change, and he became one of the
principal proponents of hypermodernism, along with Aron Nimzowitsch
and others. Indeed, with the notable exception of Nimzowitsch's
acclaimed book My System, he is considered to be the movement's
foremost literary contributor. He had his greatest early tournament
successes in the period 1918 through 1921, in tournaments in
Kaschau (Kassa) (1918, Rotterdam (1919), Amsterdam (1920), Vienna
(1920), and Gothenburg (1921). The Reti Opening (1. Nf3) is named
after him. Reti famously defeated the world champion Jose Raul
Capablanca in the New York 1924 chess tournament using this opening
- Capablanca's first defeat in eight years, the only one to Reti,
and the first since becoming World Champion. Reti was also a
notable composer of endgame studies.

In 1925 Reti set, and for a time held, the world record for
blindfold chess with twenty-nine games played simultaneously. He
won twenty-one of these, drew six, and only lost two.

His writings have also become "classics" in the chess world. Modern
Ideas in Chess (1923) and Masters of the Chess Board (1933) are
still studied today.

Reti died on June 6, 1929 in Prague of scarlet fever. His ashes are
buried in in the grave of Reti's father Dr. Samuel Reti in the
Jewish section of Zentralfriedhof cemetery, in Section T1, Group
51, Row 5, Grave 34.

Reti composed one of the most famous chess studies, shown in this
diagram. It was published in Ostrauer Morgenzeitung December 4,
1921. It seems impossible for the white king to catch the advanced
black pawn, while the white pawn can be easily stopped by the black
king. The idea of the solution is to move the king to advance on
both pawns at the same time using specific properties of the chess
geometry.
