White to move
This position came about in a miniature played by Henri Delaire against an opponent whose name was omitted from the records. It appears in the annotations to G. A. MacDonnell -- Anderssen, London 1862, which is my current Game of the Week.
The move 14.Qxf5+! is called "a magnet sacrifice" by Tartakower and Du Mont. Black's king is lured or attracted to a vulnerable square where it suffers additional assaults. Accepting the sacrifice leads to checkmate.
