Isolated Pawn Puzzle (Rated 1164): Checkmate — Bishop and Knight Mate
This puzzle shows a classic mating net where a bishop and knight coordinate to trap the king on the edge of the board. The key idea is to use a forcing check that limits escape squares, then follow with a defender-removing move that leaves the king boxed in. In practical terms, this is a clean example of a short tactical finish in the middlegame, where active pieces and king safety matter more than material count.
