Development 2
In the opening phase it is very important to mobilize pieces as actively as possible. Pieces are active if they have a lot of freedom of movement. In addition, pieces like to attack important targets. In this lesson, a particular developing move is significantly better than all other alternatives.
Also note that castling is an important developing move. By castling, you activate your rook and bring your king to safety at the same time.
What do you have to do?
Develop a piece to an active square, or choose castling.
