Caro Kann Defense Forgacs Variation Back Rank Mate in Chess

In the Caro-Kann Defense, Forgács Variation, the “back rank mate” theme happens when Black’s pieces restrict the opponent’s king and the white back rank becomes locked by pawns. The defining feature is that White’s king has no flight squares, while Black can deliver a decisive rook/queen check along the back rank or through a forced mate sequence. This is a mate-pattern classification (backRankMate) rather than a single move—your goal is to reach the specific locked-back-rank position.
