Indian
To allow the opposing king a flight, a line-piece moves across a critical square so that a second unit can temporarily occupy that square and thereby create a shut-off (subsequently moving away from the critical square).
See also: Critical move; Maslar theme; Cheney-Loyd theme.
Alias: Helpmate Indian theme.
