Figure[White to move]

Where does White have the makings of a discovered attack? This position is similar to the last one and is offered mostly for the sake of pattern reinforcement. They differ in trivial respects: the White pieces comprising the kernel of the discovery are another square apart, and this time it’s the queen rather than the bishop that is unmasked. But the execution is about the same. Black’s queen starts out as a bad target because it has protection from the knight on g7. White can eliminate the guard while unmasking the queen—and can do it with check: RxN+. After KxR, White plays QxQ and wins a queen and a knight for a rook.
