Caro Kann Defense Panov Attack Discovered Check in Chess

In the Caro-Kann Defense Panov Attack, a common structure arises after 1.e4 c6 2.d4 d5 3.exd5 cxd5 4.c4. The “discovered check” motif happens when a move (often involving a pawn break or piece repositioning) opens a line so that one piece reveals check from behind—typically along a diagonal or file connected to the king. The defining feature is that the checking piece is “uncovered” by the move, not created by a direct capture on the checking line.
