Fork
A fork is a tactic where one piece makes two or more attacks simultaneously.
If two pieces are attacked, it can be called a double attack.
The defender will find it difficult to address both threats in one move.
The attacking piece is called the forking piece; the pieces attacked are said to be forked.
