Discovered Check

Wolverhampton Chess Club


When you put your opponent in check by moving a piece that is not the checking piece, you are using the method of checking known as DISCOVERED CHECK.

The checking piece is hiding behind the piece that moves. Therefore when you move the piece that is blocking the check attack you put your opponent into check by removing the blocking piece, rather than moving the piece that finally produces the check attack.
