Academy | Tactics | Targets | Weak Back Rank
In chess, the back rank can be a weakness for both players. It is most dangerous when a king is trapped behind its pawns, as it can potentially lead to a Back Rank Checkmate.
In this position, it seems the white rook defends the back rank but black can show it is still a weakness.
