White: king h2; queen e2; rooks g1/g2; bishop d2; pawns a2/b2/e6/f2/h3. Black: king g8; queen d7; rooks a8/f7; bishop f8; pawns a6/c5/d4/f5/f6/g7/h7. Black is ahead by 2 points of material. White to move.
White's e6 pawn is a far-advanced passed pawn attacking Black's queen on d7. After 1.exd7, White trades the queen for Black's queen and the advanced pawn — a seemingly even trade, but the critical point emerges after 1...Rxe2. White plays 2.Ba5, and the bishop on a5 controls the c7 square, preventing Black's rook from queening via e1–c1–c7. More importantly, the d7 pawn is now only one move away from promotion (d8=Q), and Black's rook on e2 cannot stop it in time: 2...Re1 allows 3.d8=Q, and 2...Rd2 is similarly powerless. White's rook on g1 controls the back rank, ensuring the d-pawn promotes without interference. The combination of the unstoppable passed pawn and the bishop's control of queening squares forces a drawn or winning endgame where Black has no perpetual check or counterplay.
Recognize when a far-advanced pawn justifies trading your queen. The e6 pawn was worth more than material parity because it cannot be stopped — Black's rook alone cannot both capture on d8 and defend against White's pieces. Train yourself to calculate whether a passed pawn deep in enemy territory converts a bad trade into a drawn or winning position. The bishop move to a5 demonstrates the follow-up principle: after pushing the pawn, place your remaining pieces to escort it home, not to defend passively.
