April 21 1914
St. Petersburg International Chess Tournament, April 21, 1914 – May 22, 1914.
St. Petersburg 1914 was organized by the St. Petersburg Chess Society to commemorate its tenth anniversary. It invited the world’s top twenty players, but Amos Burn, Richard Teichmann, and Szymon Winawer declined for personal reasons. Oldrich Duras, Geza Maroczy, Carl Schlechter, Rudolf Spielmann, Savielly Tartakower, Milan Vidmar, and Max Weiss, on the other hand, declined due to tensions between Russia and Austria-Hungary.
The remaining eleven, nonetheless, made a formidable cast. These included the world champion in Emanuel Lasker, the leading title contenders in Akiba Rubinstein and Jose Raul Capablanca, former world championship contenders in Isidor Gunsberg, Frank Marshall, Siegbert Tarrasch, and David Janowski, a 19th century great in Joseph Henry Blackburne, a leading Russian master in Ossip Bernstein, and the joint winners of the 1913 All-Russian Masters Tournament in Alexander Alekhine and Aron Nimzowitsch.
