🔸 Berlin 1881
🔸 August 29 - September 17

🔰 Berlin 1881 (Germany)
CHAMPION: Joseph Henry Blackburne , 14/16 (+13 -1 =2)

▪️ The Berlin 1881 chess tournament organised by Hermann Zwanzig and Emil Schallopp, took place in Berlin from August 29 to September 17, 1881.
▪️ The brightest lights among the German participants were Louis Paulsen, his brother Wilfried Paulsen, and Johannes Minckwitz. Great Britain was represented by Joseph Henry Blackburne, the United States by James Mason, a master from Ireland. Mikhail Chigorin travelled from Russia, and two great masters from Poland: Szymon Winawer and Johannes Zukertort, also participated. Karl Pitschel, from the Austro-Hungarian Empire, arrived and played his games in the first three rounds, but was unable to complete the tournament.
▪️ The eighteen collected masters constituted a field of strength that had not been seen since the Baden-Baden 1870 chess tournament. The games were fiercely fought, as few draws were recorded, and a formula from this event would serve as a template for all future chess congresses in Germany before World War I.
