Jens Enevoldsen

Jens Evald Enevoldsen-Elsing (23 September 1907 – 23 May 1980) was a Danish chess master born in Copenhagen.

[1][2][3] Enevoldsen won the Danish Chess Championship five times (1940, 1943, 1947, 1948, and 1960).

[2] He took 4th place at the Helsinki 1947 zonal tournament; Eero Böök and Gösta Stoltz shared first place.

[4] Enevoldsen played for Denmark ten times in Chess Olympiads (1933, 1935, 1937, 1939, 1952, 1956, 1958, 1966, 1970, and 1972).

In a 1933 tournament in Copenhagen, the little known Enevoldsen defeats Aron Nimzowitsch, one of the world's leading players, with an overwhelming king's side attack featuring a rare double knight sacrifice.
