Double Check

A discovered Check is an attack on the King caused by a piece moving out of the line of a piece which he was obstructing. If the piece discovering the Check also attacks the King the Check is called a double Check.

In the scenario below, Black can initiate a double check by moving the knight on d4 to e2, putting White's king in check from both the knight and bishop.
