Figure[White to move]

This position will not be difficult if you remember to scan in all directions, including side to side. For then you see White’s rook aimed through a Black pawn to Black’s queen on the fifth rank, which means the pawn on e5 is the subject of a relative pin. The next thought should be automatic: what does the pawn purportedly defend? The knight on d4. So White plays QxN and wins a piece.
