Jens Enevoldsen Explained

Jens Evald Enevoldsen-Elsing (23 September 1907 – 23 May 1980) was a Danish chess master born in Copenhagen.^[1]

Chess career

Enevoldsen won the Danish Chess Championship five times (1940, 1943, 1947, 1948, and 1960). In 1939 he shared first but lost a playoff, and in 1950 he again shared first but lost a lottery.

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

Enevoldsen played for Denmark ten times in Chess Olympiads (1933, 1935, 1937, 1939, 1952, 1956, 1958, 1966, 1970, and 1972).^[3]

He was awarded the International Master (IM) title in 1950 and was made an International Arbiter (IA) in 1960.

Notable game

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.^[4]

Enevoldsen relates that he and Nimzowitsch subsequently became good friends, Nimzowitsch describing him as "the hope of Danish chess". At his request, Enevoldsen was buried alongside Nimzowitsch in Bispebjerg cemetery, Copenhagen.^[5]
