Conducted as part of the 6th Rheinische Schachcongress in Köln. (The 6th
Congress was originally planned to be held in 1866, but was cancelled. See
Westdeutsche Schachbund, 1866 for further information.)
Ten sets were received, one of which was retracted by the competitor.
The original announcement included R. Lichtenscheidt as a judge instead of A. Keller, and did not mention a referee. G. Schnitzler was mentioned as a fourth judge, but was unable to participate due to lack of time.
The report mentions that in difference to earlier tourneys, where the judges conferred during the congress, in this tourney each judge issued his own report, which were sent to E. Hammacher for final decision on awards. As the remaining three judges reached the same verdict, there was no need for further adjudication.
The report does not indicate that there were any issues with any of the prize-winning sets, but Braune's set does not appear to have been published in full. K. Kockelkorn's report, printed a few months later, says that only problem 3 of Braune's set survived testing, but as he considered it to be the best single problem of the tournament, he gave it precedence to other fully correct but otherwise less interesting sets. (Problem 1 of the set suffered from a short solution as well as duals, and in problem 2 the mainplay could be bypassed: see below.)
