Loyd's clearance

A piece moves along a line, crossing a critical square, so that a like-moving piece arriving later on the line can take advantage of this by moving to an opposite direction. The line-clearing piece does not support the second piece like, for instance, in Turton doubling.

See also: Turton doubling; Brunner-Loyd clearance.

Alias: Loyd's line clearance; Loyd's line voidance; Loydschen Linienräumung (Ger.).
