BOGOLYUBOV (1889-1953) Bogolyubov was an attacking player, to be ranked with Anderssen, Marshall, and Spielmann. With subtle positional play he was less at home; though in his later years he did operate routinely on positional grounds while producing many fine endgames. Bogolyubov was an optimist. One of his famous aphorisms was "When I am White I have the advantage because I am White; when I am Black I have the advantage because I am Bogolyubov" His aims, however, were apt to outrun his capabilities. His great talent was at times just not great enough, and the occasional gross errors in his play were due to this disharmony} 1. e4 {Around 1928 Bogolyubov wrote a book on the d-pawn opening, under the title 1. d2-d4. However, later in his career he usually preferred 1. e4} 1... c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nf6 5. Nxf6+ exf6 6. Bc4 Bd6 7. Qe2+ Be7 8.
