Discoverd attack + trapping

This lesson combines the discovered attack with trapping.

What should you do?

Win material by trapping a piece with a discovered attack.


The white knight and the bishop form a battery. Removing the knight causes the bishop to attack the queen. However, with square b7, the queen has another escape square. By playing 1.Nc5! white not only attacks (2x!) the queen, but also takes the escape square away from the black queen. The queen is trapped!
