Setting up a skewer: sacrifice (3)

In this lesson we see the forcing moves of checks and captures in action. As in the previous two lessons, material is sacrificed to set up a combination, in this case a skewer.

In Example 1, You prepare a skewer by luring an enemy piece to the same file as another piece. Example 2 deals with eliminating the defense.

What do you have to do?

Sacrifice a piece by capturing with check. This way you can prepare a skewer that wins material.
