Nick Kampars introduced that game, Dahlen-Botvinnik, in the October 1965 issue of his Opening Adventures:
BOTVINNIK MEETS THE B.D.G.
On January 26, 1962 the World Champion, M. Botvinnik, possibly for the first time in his career, met the B.D.G. in a simultaneous exhibition in Stockholm, Sweden. The Champion chose the so-called 0'Kelly Defense (4. P-B3, P-B3) in response to the gambit. It is interesting to note that the Champion could only draw against our favorite gambit.Here are the two games:
