{[%mdl 194] The American Harry Nelson Pillsbury was one of the brightest stars
to ever sparkle in the chess firmament. He never played in a world
championship match, but for a year he was considered the future of the game.
His sensational victory in his international debut at the Hastings Christmas
tournament 1895/96, ahead of the newly crowned world champion Lasker, won him
a place amongst the very best players. At the time there was an uncertainty
about the true hierarchy at the top of the chess world, which made new
contests inevitable. To clarify the situation five of the best players in the
world were invited to a tournament in St. Petersburg in 1896: Lasker, Steinitz,
Pillsbury, Chigorin and Tarrasch (at the last moment Tarrasch cancelled his
attendance because of his duties as a medical practitioner). Each player
played six games against each of the others. After three rounds Pillsbury was
in the lead and Lasker was second, but even he was badly losing his
micro-match against Pillsbury 2 1/2 : 1/2. It was only due to Steinitz'
successful performance against the leader that Lasker managed to remain in
contention, just one point behind Pillsbury. The following game was played in
the fourth round. If Pillsbury would win, the outcome of the tournament would
be more or less clear. And then the chess world would call into question the
legitimacy of Lasker's title, forcing him to play a new match for the world
championship with this young energetic opponent under very unfavourable
circumstances.} 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Nf3 c5 5. Bg5 cxd4 6. Qxd4 Nc6

this fascinating human drama. "Too many mistakes" you say? Please don't rush
to write off this game. Remember its unique historical importance! That day
Caissa chose Lasker, and as we know today, the chess goddess did not err. Her
cruel decision marked a fork in the lievs of both players. Lasker, inspired by
this victory, won the tournament convincingly. Later that year he crushed
Steinitz in a rematch and kept his title for 25 more years! Pillsbury, after
the above disaster, collapsed and lost five games out of the remaining eight,
ending up third behind Steinitz. He never achieved the same peak of playing
strength as in that magnificent year and died eight years later at the age of
34. Who know how often Harry Nelson Pillsbury remembered that traumatic day in
St. Petersburg and the chances he had missed - chances that would have changed
his entire life and the course of chess history. womit ein faszinierendes
menschliches Drama zu Ende ging. "Zu viele Fehler" sagen Sie? Bitte schreiben
Sie nicht diese Partie zu schnell ab. Denken Sie an ihre historische
Bedeutung! An jenem Tag entschied sich Caissa für Lasker, und, wie wir heute
wissen, irrte die Schachgöttin nicht. Ihre vielleicht etwas grausame Wahl
markierte eine Wende im Leben der beiden Spieler. Lasker, von seinem Sieg in
dieser Partie inspiriert, gewann das Turnier in überzeugender Manier. Später
im gleichen Jahr zerschmetterte er Steinitz im Rückkampf um die
Weltmeisterschaft. Er behielt den Titel für weitere 25 Jahre! Pillsbury
dagegen brach nach diesem Desaster förmlich zusammen, verlor fünf von den
nächsten acht Partien und beendete das Turnier als Dritter hinter Steinitz. Er
konnte nie wieder den gleichen Gipfel der Spielstärke erklimmen wie in diesem
glorreichen Jahr. Er starb acht Jahre später im Alter von 34. Wer kann wissen,
wie oft er diesen traumatischen Tag in St. Petersburg durchlebt hat und dabei
an die verstrichenen Chancen denken mußte – Chancen, die sein Leben so
gründlich geändert hätten.} 0-1
