Definition of the Schiffmann defense: "White threatens with discovered mate. Black defends by self-pinning his own piece, which would be unpinned by the threat. White utilizes this pin in mate." (Encyclopedia of Chess Problems) Invented in 1928 by the Romanian composer Israel A. Schiffmann (1903-1930)

Александр Сергеевич Кузовков (*27.2.1953 in Provideniya) Russian composer and Grandmaster, see wikipedia de, it, lv, ru. "Kuzovkov is a constructions engineer and also an excellent direct mate composer. What is noteworthy is that Aleksandr Kuzovkov, beside this 1st place in the WCCT, has also won 2 second places and 3 third places in WCCT tourneys!"
