Setting up a skewer: threat (1)

In this lesson you will learn how to prepare a skewer by means of a threat. As you know, by a threat you can think of attacking a piece, a mate threat, or threatening to promote. In Example 1 we look at attacking a piece and in Example 2 we look at a promotion threat. In both cases, a skewer is prepared.

What do you have to do?

Create a threat and prepare a skewer. Then, win material with a skewer.
