Dutch Defense Leningrad Variation Discovered Check in Chess

In the Dutch Defense Leningrad Variation, the “discovered check” motif happens when a piece moves away (often from a line on the dark squares) and reveals a check on the enemy king. A defining feature is the Leningrad setup with …Nf6 and …e6, where the dark-square bishop/queen line can become active after a tactical displacement. The discovered check is the moment that the “uncovered” line delivers check immediately after the blocking piece shifts.
