From the October 1965 issue of Nick Kampars' Opening Adventures:
In the July,1965 issue of "Chess", edited by B.H. Wood, a contest for brilliant games was terminated with the following comment: "Our second great contest for brilliant games of 25 moves or less drew 129 entries from all parts of the world.... we have decided to divide the two cash prizes between three competitors,all from overseas: Dr. R. Cherubim,Saarland, Germany; D. Gedult,Paris,France ; and K. Winterton, Ottawa,Canada" . The following game from this contest was a BDG., a "natural" brilliancy. It was played at the Cercle Cassia, Paris,in March, 1965. Notes are by the winner.

[#] 1.d4 Nf6 2.f3 d5 3.e4 Transposing into the BDG, which I never fail to employ--at least for the first time--when playing against a master; and it has scored at least 90% for me. 3...dxe4 4.Nc3 e3 A master knows when to hand back the pawn--which he does not need for winning a game against an obscure opponent... 5.Bxe3 Now see how the bishop and f-pawn are badly placed, aren't they? 5...Bf5 6.Bd3 Not because I really intended exchanging pieces, but, as in most such games, when I castle queen's side, I didn't want his bishop staring at my c2, which after 0-0-0 becomes a weak point... 6...Bxd3 7.Qxd3 g6 8.O-O-O Bg7 9.Qd2! Just to disquiet him a bit. 9...h6 10.Nge2 Nbd7 11.Kb1 e5 12.d5 g5 After all, he would like to castle. 13.Ng3 O-O 14.Nf5 Nh7 He smells a rat and would be glad to change the bishop for that damned knight, but I'm not in a hurry. 15.h4 f6 16.g4 Nb6 17.Qd3 Qd7 18.hxg5 hxg5 19.Rxh7 Kxh7 20.Ne7+ f5 21.Rh1+ Bh6 22.Nxf5 Resigns. [1-0]
