Attacking squares

In this lesson, you will learn that attacking squares can be just as important as attacking pieces. Obviously, this only applies to squares that are important to your opponent. Such key squares are, for instance, promotion squares or mating squares.

So, search for more attacking options: Besides threatening your opponent's pieces, try to control important squares. 

What do you have to do?

Win material by means of a double attack. Remember: you can attack both pieces and squares.
