Bishop Sacrifice Puzzle (Rated 1347): Crush the Endgame — Advanced Pawn Promotion

This chess endgame is built around an advanced pawn that becomes the main tactical target. In simplified positions, a single passed pawn can decide the game if it is supported by active pieces and king activity. Here, the side with the initiative uses forcing captures and pawn advances to convert a small edge into a winning material sequence. The key lesson is that endgame tactics often come from pawn races, not just direct attacks on the king.
