Learn How to Promote: Pawn Promotion
This puzzle is a classic chess endgame tactic built around promotion and a forcing mating net. Black’s advanced passed pawn is the key asset, but the real point is that the position is tactically loaded: the enemy queen and rook are vulnerable, and the king has very little room. In positions like this, a quiet-looking forcing move can create a direct threat that cannot be met without allowing a back rank mate or immediate promotion-based checkmate.
