Study of the Month: Endgame Studies, Endgame Theory

Endgame studies sometimes go to extremes, e.g. by demonstrating a win in 584(!) moves in a study, in which King, Rook, two Bishops (standing on the same colour), and pawn fight against King, Queen and Pawn. But are these and similar studies relevant for the theory of the endgame or practical games? It depends. Siegfried Hornecker takes a closer look.
