Squares & disco attacks

Let's return to attacking a mating square. In addition to the double attack, you can also use the discovered attack to attack both a piece and mating square at the same time.

What do you have to do?

Use a discovered attack to gain material. You can do this in two ways:

- Use the piece in front of a battery to attack a piece and attack a mating square with the piece behind.

- Attack a mating square with the piece in front and uncover an attack on an enemy piece with the piece behind.

You are already familiar with this, but it never hurts to refresh your memory. Fast-forward to the example!
