Black moved the queen from c6 to c7 (25…Qc7). The move does nothing to address White’s looming threats – the pawn on d5 can advance with tempo and the rook on f7 (or the pawn on f7) is vulnerable. Moreover, the pawn on e7 becomes completely undefended, giving White a target. White retains the initiative with threats of d5 and f7.

The engine’s recommendation 25…Qe3 creates a direct counter‑threat by attacking White’s king on b1 and the rook on h2, forcing White to respond defensively. After 25…Qe3 White cannot continue the d5 push without losing material, and Black gains the tempo needed to consolidate the position. By playing Qc7, Black missed the chance to seize the initiative and left a pawn (e7) hanging, allowing White to improve the position.

Prioritise active counter‑play over passive moves – when the opponent threatens, look for moves that create your own threats, especially checks, rather than idle repositioning.

Black delivered a check with the queen moving from c2 to c1 (54…Qc1+). The check forces the white king on a3 to move, but it does not end the game immediately. After the forced king move, Black can continue the attack and eventually force mate, though a few more moves are required.

The engine’s line 54…Qb2# is a forced mate in one, delivering checkmate directly on b2. While 54…Qc1+ is still winning, it allows White an extra move (Kd2) before the final blow. Choosing the immediate mate removes any chance of a defensive resource and ends the game cleanly. The player’s move is solid, but the engine’s move is objectively superior because it finishes the game instantly.

When you have a forced mate, always take the quickest finishing move – even a winning move is suboptimal if a shorter checkmate exists.

Black checked the white king on a2 by moving the queen to c2 (55…Qc2+). The move forces the white king to move, but it does not deliver immediate mate. Black still retains a dominant position with the queen and king deep in White’s territory.

The engine’s move 55…Qb2# gives a direct checkmate. By playing Qc2+, Black allows the white king a legal move (Kb1), extending the game unnecessarily. The queen on b2 attacks the king on a2 and also covers the escape squares, leaving no defense. The engine’s move is superior because it ends the game instantly, whereas Qc2+ merely continues a winning sequence.

Always look for the mating net – if a checkmate is available, choose it over any other checking move.

Black delivered checkmate with 73…Qc4# (queen from d4 to c4). The move mates the white king on a2; all escape squares are covered by the queen on c4, the pawn on a4, and the black king on c3. No defensive move exists for White.

The engine’s alternative 73…Qdf2# also mates, using the other queen on d4 to move to f2. Both lines achieve the same result, but the player’s choice Qc4# is perfectly correct and immediate. It demonstrates precise calculation of the mating net and proper coordination of the two queens.

Coordinate multiple pieces to deliver a forced mate – when you have two heavy pieces, align them so that every escape square is covered, ensuring an unstoppable checkmate.
