Promotion Puzzle (Rated 1451): Force Mate in 2 — Promotion Tactic

This puzzle is a classic forcing sequence built around an advanced pawn and a mating net. White’s heavy pieces are active, but the key idea is not material gain—it is to use a forcing check that drives the king into a helpless line. The position also highlights how a passed pawn can become decisive when it promotes with tempo. In practical classical chess, these motifs often appear in sharp middlegames where king safety matters more than raw material.
