Special attacks: discovered attack (2)

Do you remember the double attack on a piece and a mating square? You can do the same thing with a discovered attack!

Have a look at the example. White can threaten mate while at the same time attacking a piece. Another smart move to win points!

What do you have to do?
Use a discovered attack to win material. You can do this in two ways:
1. The front piece attacks a piece. The back piece attacks a mating square.
2. The front piece attacks a mating square. The back piece attacks a piece.
