French Defense Normal Variation Discovered Check in Chess

In the French Defense Normal Variation, a “discovered check” happens when one piece moves away (often a pawn or minor piece) to reveal a line of attack on the enemy king. The defining feature is that the move both opens a rook/bishop/queen line and creates an immediate check, turning a seemingly quiet move into a tactical strike. In this motif, the check is “discovered” because the checking piece was blocked until your move removed the obstacle.
