The chess openings
A manual of chess openings by the English player Henry Edward Bird, published in New York by H. Lockwood in 1880 for club and amateur players studying published games. The plates are square wood-engraved board diagrams, cross-hatched dark squares against plain ones, with small silhouetted pieces—crowned kings and queens, mitred bishops, horse-head knights, round pawns—usable as grid patterns, game-piece icons, or endgame position motifs.
