Doppelkopf

German

From doppel- (“double”) +‎ Kopf (“head”).

Doppelkopf n or m (strong, genitive Doppelkopfes or Doppelkopfs or Doppelkopf, no plural)

(card games) A trick-taking game for four players, popular chiefly in the northern half of Germany, consisting of several rounds in which the players are assigned (based on the cards they are dealt) to two initially unrevealed sides of two, most often played with two decks from 9 to ace (48 cards).
- 1972 June 28, Walter Rauff, Vernehmungsniederschrift‎^[1]:
  In diesem Zusammenhang möchte ich auch noch einmal wiederholen, dass Heydrich beim Spiel nicht verlieren konnte und dass deswegen meine Kameraden und ich uns in Prag dahin verständigten, ihn beim Doppelkopf gewinnen zu lassen.
  In this context I also want to repeat again that Heydrich was a sore loser at games and that therefore my comrades and I at Prague agreed among ourselves to let him win at doppelkopf.
