A recent game from the Brazil Open in Rio de Janeiro transformed into a line in the O'Kelly Defense to the BDG (1. d4 d5 2. e4 dxe4 3.Nc3 Nf6 4. f3 c6), reaching a position from a game well known to BDG players.
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.
