French Defense Steinitz Variation Discovered Check in Chess

In the French Defense Steinitz Variation, the “discovered check” happens when a piece moves away (often from a line like the diagonal or file) and reveals a check on the enemy king. The defining feature is that the check is not delivered by the moving piece itself, but by the piece newly exposed behind it. In this Steinitz structure, tactics often revolve around central tension and lines opening for bishops/rooks after a forcing move.
