Prokeš_maneuver
Ladislav Prokeš (7 June 1884 – 9 January 1966) was a Czech chess master and one of the most prolific composers of endgame studies in chess. He was born and died in Prague.[1]
Prokeš was joint Czech Champion in 1921[1] and played for the Czech Olympiad team in 1927, 1928, and 1930.[2] While a strong tournament player, it is his chess compositions that gained him fame. In 1951 he published a collection of studies "Kniha šachových studií". His 1,159 endgame studies, as listed in Harold van der Heijden's database, rank fourth among all composers.[3]
