The convention of White having the first move is much more recent than that. François-André Danican Philidor in the original (1749) edition of his famous treatise "Analyse du jeu des Échecs" cited one game in which Black moved first. Johann Horny, in a book published in Germany in 1824, wrote that Black moves first. Phillip Sergeant wrote in his book "A History of British Chess" of the great Alexander McDonnell (1798–1835), remembered today for his series of matches with Labourdonnais: He preferred to have Black, as first player as well as second ... this was a common fad in his day, which persisted with a great number of players, as a study of the "Chess Players' Chronicle" and other magazines shows. In the Immortal Game (Anderssen–Kieseritzky, offhand game, London 1851), one of the most famous games in history, Anderssen had the Black pieces but moved first. He also took the Black pieces but moved first in the sixth, eighth, and tenth games of his famous 1858 match against Paul Morphy. Each of those games began 1.a3 e5 2.c4, when Anderssen was effectively playing the Sicilian Defense with an extra tempo.
