Alekhine Defense Scandinavian Variation Discovered Check in Chess

In the Alekhine Defense Scandinavian Variation, a “discovered check” happens when one piece moves away to reveal a line-check on the enemy king. The defining feature is that the move creates a new attack along a rook/queen/bishop line while the opponent’s king is already vulnerable on that line. In this motif, the Alekhine setup often places pieces so a tactical reveal can come with tempo.
