The tournament and its record
Ehrhardt Post won the master tournament of the twenty-first German Chess Federation congress at Hamburg, held from 18 to 30 July 1921. His 8½ points from eleven games put him a point ahead of Friedrich Sämisch. Willi Schlage finished third on seven.
All sixty-six games of the twelve-player round robin are available. The congress also held lower sections and an amateur playoff; those were separate competitions. Individual game dates are unknown in the preserved source, so the archive retains its partial dates.
