What is a knight fork in chess?

A knight fork occurs when a knight attacks two or more pieces simultaneously. Because knight attacks cannot be blocked, the opponent usually has to move one target and concede the other. Checks make knight forks particularly powerful.

How can I win material when my piece is attacked?

What is an overloaded defender in chess?

How does a chess quiz improve tactical calculation?
