Setting up a skewer (2)

In the previous lessons, two opposing pieces of the defending side were already on the same line (file, rank or diagonal). In the next three lessons, you will learn that by playing forcing moves, you can also get pieces that are not yet on the same line to be on the same line one move later. Then a skewer wins material.

In this lesson we focus on checks.

What do you have to do?
Give check and to force the king in an unfavorable spot. Subsequently win material with a skewer.
