Novotny (chess)
From Wikipedia, the free encyclopedia
This article is about the Novotny chess device. For other uses, see Novotny (disambiguation).
The Novotny (also often spelled as Nowotny, even in non-German sources) is a device found in chess problems named after a problem from 1854 by Antonín Novotný, though the first example was composed by Henry Turton in 1851. A piece is sacrificed on a square where it could be taken by two different opposing pieces, but whichever makes the capture, it interferes with the other. It is essentially a Grimshaw brought about by a sacrifice on the critical square.
This pattern can arise as part of a combination in an actual game, but it is extremely rare (see games below). Most chess players would not use the term "Novotny" to describe such a move, since that term is almost exclusively used in the context of chess problems.
