Johannes Kohtz
Johannes Kohtz (born July 18, 1843 in Elbing ; † October 5, 1918 ) was a German chess composer and, together with Carl Kockelkorn, founder of the New German School of Chess Composition .
Kohtz and Kockelkorn
Johannes Kohtz moved to Cologne with his parents. There he met Carl Kockelkorn. As a schoolboy, the two were already occupied with chess compositions. Wilhelm Kufferath made it possible for them to publish their own compositions at the age of 17 in the Sunday papers for chess friends . The two composers particularly liked Philipp Klett's assignments.
Kohtz and Kockelkorn agreed so much in their views on chess composition that after a short time they published all exercises as joint works. Rumors that individual compositions were also published as collective works ended in 1870 by Kohtz who stated in the chess newspaper that the two friends composed together on the board for every task.
After Kohtz and Kockelkorn in 1903, half a year after Arthur Gehlerts first attacks against Bergers Old German School, her important book The Indian problem had published, there were discussions with Johann Berger , the founder of the old German school . This correspondence from Kohtz was printed in the German weekly chess. Berger held against it in the German chess newspaper. Kohtz put forward better arguments that the New German School supplanted the Old German School. The discussion was interrupted by the First World War.
After Kockelkorn's death on July 16, 1914, Kohtz continued to publish under the names of both authors. A task that appeared in 1911 gave its name to the German composers' association " Schwalbe ", which was later founded (see there).
The Roman
One of the most fruitful compositional ideas that Kohtz and Kockelkorn formulated and implemented is the so-called Römer. It goes back to a four-move from 1905, which the authors dedicated to Augusto Guglielmetti, President of the Italian Chess Federation, who lives in Rome. In Romans, a black defender is guided by a preliminary plan to a parallel on which an analogous defense is available to him. However, this is associated with damage that white is able to use.

Against 1. Qe2? The black bishop defends with the intention of 2. Bd3 and 3. Qc2: 1.… Bg5! 2. Bd3 Bxe3!
Therefore, White steers with the preliminary plan
1. Nb7 – d6! (threatens 2.Ne4 mate)
the runner on a parallel:
1.… Be7xd6
An analogous defense is now available against the main plan (Qe2):
2. Qf2-e2 Bd6-f4
But this is associated with damage: The defender can be beaten (Schlagrömer) , a new mate is possible.
3. e3xf4 Kc3xd4 4. Qe2 – e5 with pattern mate .
The “Roman parallelogram ” is described here by the fields e7 – g5 – f4 – d6.
Private
Johannes Kohtz studied in Berlin and Karlsruhe. He worked as a senior engineer in a factory for railway wagons in Elbing and Königsberg. From 1901 Kohtz lived as a pensioner in Dresden and met Arthur Gehlert. After his death, his chess book collection was transferred to the Saxon State Library in Dresden in accordance with a will . His gravestone is in the urn grove in Dresden-Tolkewitz.
