Lehrbuch des Schachspiels mit besonderer Berücksichtigung des Gambitspiels, nebst einer systematischen Anleitung zum kleinen Kriegs- und sinesischen Schachspiel. Miteinem Anhange Die Geschichte des Schachspeils
An 1845 German chess instruction manual by Hirsch Silberschmidt, published in Wolfenbüttel by the Holle bookshop and aimed at students of chess and its gambit openings. Its pictures are plain diagrams: a chessboard with German piece abbreviations such as Kn, Gd and Cr over algebraic coordinates, a second board of letter-and-number squares, and a grid of circular markers with a crossed-out region for a Chinese-style variant. A designer could take the clean grid layouts, coordinate labels and simple engraved symbols as a model for schematic or game-board graphics.
