Debrecen 1925
Compiled by Phony Benoni

The tournament was held in Debrecen, Hungary from August 9-24, 1925, with the following players.

Lajos Asztalos, Ernst Gruenfeld, Kornel Havasi, Paul F Johner, Hans Kmoch, Hermanis Karlovich Mattison, Geza Nagy, Ladislav Prokes, David Przepiorka, Jakob Adolf Seitz, Lajos Steiner, Savielly Tartakower, Dr. Arpad Vajda, Vladimir Vukovic

Chessmetrics estimates this as a Category 11 tournament with an average rating of 2508.

Hans Kmoch had one of his finest results, winning with a margin of 1 1/2 points. He and Geza Nagy were the front-runners at the halfway mark with 4.5/6. Both lost in round 7, and drew in round 13. In between, Kmoch won five in a row while Nagy lost an additional five in a row!

And Kmoch needed those wins. Johner had taken the lead in round 7, and stayed ahead until a draw with Gruenfeld and loss to Tartakower allowed Kmoch to coast home in the last round.

A noteworthy happening was the congestion in the lower ranks, as only five of the 14 players could finish over 50%.
