French Defense Rubinstein Variation Discovered Check in Chess

In the French Defense Rubinstein Variation, the discovered check motif appears when a piece moves away (often from the d-file or a diagonal line) and reveals an attack on the enemy king. The key feature is that the “uncovered” line is already aimed at the king, so the move itself creates check rather than simply improving a piece. In practice, it’s most common around the central/queenside pieces after the Rubinstein setup, where lines on the king become temporarily blocked.
