Bukovina theme

In the diagram position a white piece controls a black king's flight. Black captures that piece and subsequently self-blocks the flight-square that white piece controlled previously.

In the reverse form of the Bukovina theme, Black first self-blocks the flight-square and later other black piece captures that white piece.

Alias: Nagnibida theme.
