PHILIDOR, François-André Analyse du jeu des échecs. With a new abbreviated notation, and forty-two plates where is represented the situation of the game for cross-references and endgame. New edition [...]. Philadelphia J. Johnston [ca. 1821] 8vo: -150 pp.; 21 pl. (author's front. pasted on, probably coming from the orig. wrappers, spotted). Quarter brown sheep, marbled paper on boards, flat spine (rubbed, def. on head and tail), marbled endpapers. Later edition (first 1749) and one of at least three similar editions (two 12mo and one 8vo, one with imprint dated 1821, the other two with the same place, publisher and printer, undated), of this analysis of the game of chess by the French composer and chess player Philidor (1727-1795). In 1803 Montigny renewed Philidor's work introducing a more brief chess notation and the 21 coloured plates with 42 chess positions. The chess boards are printed in green and white, the chess pieces are indicated by capitals in black and red. It has been said that Philidor was the best chess player of his age, once playing three blindfold games simultaneously at a chess club in London. A well-known chess opening and checkmate pattern are both named after him. With a list of booksellers on verso half title. This list appears in all three "Philadelphia" editions. It's been thought that the "1821" edition is typographically European, not American. Both "Johnston" and "Lafourcarde" differ from the names "Johnson" and "Lafourcade" found in Philadelphia imprints of the period. Given the list of European bookellers, it has been concluded that the Philadelphia editions were printed in Belgium, to rival Causette's edition (Paris, 1820) (Worldcat, George Allen, The Chess Monthly, v. 1, p. 287).
