Squares & disco attacks

Back to attacking a mat square. In addition to the double attack, you can also use the discovered attack (a form of the double attack) to attack both a piece and mat square at the same time.

What to do

Use a discovered attack to gain material. You can do this in two ways:
- Attack with the front piece a piece of the other. Attack a mat square with the back piece.
- Attack a checkmate square with the front piece. With the rear piece, attack one of the other's pieces.

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