White: king h3; queen e3; rook c1; pawns a4/b3/e4/f4/g3/h2. Black: king h8; queen b2; rook d4; pawns a6/b7/e5/f6/g7/h6. Material is balanced. White to move.
White's 1.Qc5 deflects Black's queen from defending the back rank and the rook on b4. The queen must move to stop the threat of 2.Qf8#, and every queen retreat abandons the rook's defender. After 1...Qxb3 (Black's most forcing try, capturing material), 2.Qf8+ forces 2...Qg8 (the only move preventing mate on h8), whereupon 3.Qxb4 wins the rook cleanly. The deflection works because Black's queen was the sole guardian of two critical squares—g8 and the rook itself—and White's check sequence forces it to abandon one to prevent the other. The combination is forcing throughout: 1...Qxb3 is met by check, 2...Qg8 is forced (any queen move loses to 3.Qh8#), and the rook falls.
Recognize deflection patterns where the defender guards both an escape square and the piece being attacked. Look for moves that attack the defender directly, forcing it to choose which duty to abandon. Here, Qc5 threatens f8 and implicitly threatens the rook; Black's queen cannot defend both at once when a forcing check lands on the next move. This pattern—a quiet move that poses two problems, resolved by a follow-up check—is the hallmark of a long combination.
