John Roycroft, 1988 [1]

Arthur John Roycroft, (born July 25, 1929)
an English chess endgame study composer, international judge, and author. He is co-founder and member of the Chess Endgame Study Circle, founded on March 16, 1965, publishing the studies magazine End Game (EG) [2] . Roycroft was its publisher for the first 102 issues, from July 1965 until 1991. Since then, the Dutch-Flemish ARVES, the Alexander Rueb Vereniging voor Schaakeindspelstudie [3] has been publisher, but Roycroft stayed as editor-in-chief until 2007, superseded by Harold van der Heijden [4]. Roycroft's adaptation of the GuyBlandford code in the 70s resulted in the GBR code, an efficient way to index any chess position, in particular endgame studies [5].
