Black played 20...b6, a pawn push on the queenside. The move does nothing to address Black's most urgent threat – the looming ...f2+ check – and it weakens the c5 square, which White can exploit with the knight or a pawn advance. Meanwhile, Black's pieces on a8, e7 and g8 are left undefended, and White's b3 pawn becomes a tactical target.

The engine's top move 20...Ne5 immediately confronts White's attack by centralising the knight, eyeing the f3 and g4 squares, and covering the critical f2 square. By placing the knight on e5, Black not only defends against the immediate mate threat but also creates counter‑play against White's c5 and d7 ideas. The move keeps the queenside pawn structure intact and forces White to respond to the active piece rather than gaining tempo with pawn pushes.

Prioritise king safety and active piece placement over pawn moves: When the opponent threatens a direct check or mate, address the threat first with a piece move that also improves your position.

Black captured on c6 with 37...Rxc6, eliminating White's active rook on c6. This exchange removes a powerful attacker, clears the c‑file, and leaves Black with a material advantage while maintaining a safe king. The move also eliminates White's bishop on d5's support for the c6 square, reducing White's counter‑play.

The engine confirms 37...Rxc6 as the optimal continuation. By removing the opponent's rook, Black not only wins material but also simplifies the position into a winning rook‑and‑pawn endgame. Alternative moves would allow White to keep the initiative with Bxc6 or maintain pressure on the seventh rank, which could lead to perpetual threats.

Exchange when it wins material and reduces opponent's activity: Capturing a key piece that supports enemy threats can turn a complex position into a clear winning endgame.

Black played the knight jump 51...Nd4, centralising the knight on a strong outpost. The move attacks the White bishop on b7 and supports the advance ...e3, while also cutting off the White king's escape routes. No immediate threats exist for White, and Black's pieces are well coordinated.

The engine also lists 51...Nd4 as the best move, confirming that the knight placement maximises piece activity and creates multiple threats (e.g., ...e3 and ...f3). Any other move would leave the knight passive and miss the chance to dominate the dark squares, allowing White to regroup.

Place knights on outpost squares where they attack key enemy pieces and support pawn breaks: A well‑placed knight can dictate the flow of the game.

Black delivered the final blow with 64...Nf2#, a knight move delivering checkmate. The knight on f2 covers the only escape squares for the White king, while the pawn on g3 and bishop on b7 restrict all other routes. White has no legal moves, and the game ends.

The engine's suggestion is exactly 64...Nf2#, confirming that this is the only winning move. Any other move would either allow White to escape or prolong the game unnecessarily. The move exploits the coordination of Black's pieces to create a forced mate.

Coordinate pieces to deliver a forced mate: When the opponent's king is confined, look for the move that simultaneously checks and covers all escape squares.
