Somov mate

Black either blocks a thematic square (block Somov, Somov B2) or opens a white line to guard a thematic square (line-opening Somov, Somov B1), thus enabling White to close a guard line to that square in the mate. [FIDE Album]

See also: Anti-Levman mate.

Alias: Somov 1/2; Somov B1/B2; Theme B/B2.
