ABSTRACT

Amelung (1842-1909) was a famous Latv ian

chess endgame analyst and problem com­

poser.

Figure 2. (S. Loyd, Musical World, 1859) 1 Q a l would threaten mate by 2 Qh8, and Black's only defense would be to castle. C a n he do so? Well, Black's last move cannot have been with a pawn, since neither of his pawns has moved, so it must have been with the king or the rook. Hence he has lost his right to castle, and 1 Q a l does indeed force mate in two. Sam Loyd (1841-1911) was America's most famous puzzlist, whose work has been featured in Martin's books right from the start.
