Emil Diemer was a deeply troubled chess player. He was the co-author of the Blackmar-Diemer Gambit, a committed madman, forbidden to play chess by his doctors, and disturbingly, the official chess reporter of the Third Reich. For a good summary of his troubled life, see the link below. In this game, he plays according to his aggressive principle, but at the critical moment, it is Trommsdorf who plays an INSANE move and SHOULD have won the game.
