Black played 53...Be2, sliding the bishop from h5 to e2. The move blocks White’s central pawn thrusts (c6, e4) and simultaneously attacks the white knight on c1 while defending the a7 pawn that White is eyeing. Threats show Black only worries about a7, while White threatens c6 and e4. By placing the bishop on e2, Black neutralises both threats: the bishop controls c4‑e2‑g4 diagonal, limiting White’s pawn breaks, and it also covers the a7‑square, preventing White’s rook from infiltrating.

The engine also recommends 53...Be2, confirming that the bishop move is the most accurate. Any alternative (e.g., retreating the bishop or moving a pawn) would leave the a7‑square vulnerable and allow White to advance c6 with tempo, gaining a passed pawn. Be2 also prepares possible tactics such as ...Nd3+ after White’s next move, exploiting the now‑exposed white king. By choosing the engine‑approved move, Black maintains material equilibrium and curtails White’s active plans.

Neutralise opponent’s active pawn breaks: When the opponent threatens central pawn pushes, a well‑placed piece (here the bishop) can both defend key squares and limit those advances, preserving the balance.

Black advanced the pawn with 64...f2, pushing the pawn from f3 to f2. This creates a passed pawn but also opens the diagonal for White’s rook on g5 and leaves the black bishop on d1 without a defensive role. White’s threats (d5, g2) become more potent, and the pawn push does not address the immediate danger of Rxg5+, which would win material and expose the black king on e1.

The engine’s top continuation is 64...Be2, retreating the bishop to e2 where it both blocks the rook’s line on the g‑file and prepares to meet White’s d5 push with ...Bxd5. By keeping the bishop active, Black maintains control of critical squares and avoids the tactical shot Rxg5+. After ...Be2, Black can later support the f‑pawn with ...f1=Q if the position allows, but only after solidifying the king’s safety. The pawn break f2, while ambitious, loses a tempo and gives White the initiative.

Don’t create weaknesses for short‑term gains: Advancing a pawn that creates a passed pawn is attractive, but if it opens lines against your king, the resulting tactical liabilities outweigh the material prospect.

Black delivered 69...Qb5+, checking the white king on c3. The queen move forces the white king onto a vulnerable square and sets up a forced mating net. White’s only realistic replies are forced moves that allow Black’s pawn on g2 to promote (as indicated by the engine’s continuation 69...g1=Q+). The position’s threat list shows no immediate white threats, while Black’s queen check dominates the board.

The engine’s suggested line continues with 69...g1=Q+, a promotion that immediately forces mate after 70.Re3 (the only move to block). By playing Qb5+, Black creates a decisive tempo, drives the white king into the corner, and ensures the pawn promotion is unstoppable. Any alternative, such as a quiet move, would allow White to consolidate and potentially escape the mating net. The queen check is the most forcing move, converting material advantage into a forced mate.

Use checks to drive the king into a mating net: When you have a passed pawn ready to promote, a well‑timed queen check can force the opponent’s king onto a square where promotion becomes decisive, turning a material edge into a forced win.

Black played 73...Qe3#, delivering checkmate. The queen on e3 attacks the white king on e1, and the black bishop on e2 covers the escape squares, while the rook on e5 cuts off the king’s flight. White has no legal moves; all escape squares are either occupied or controlled, resulting in immediate mate.

The engine’s top move is exactly 73...Qe3#, confirming that this is the only winning move. Any other move would allow White to survive, potentially drawing the game. The queen’s placement simultaneously checks the king and mates because the bishop on e2 controls d1 and f1, and the rook on e5 controls the e‑file, leaving no defensive resources for White.

Coordinate pieces for a forced mate: A queen, rook, and bishop can combine to cover all escape squares around the enemy king. When the pieces are harmoniously placed, the final move can be a simple check that is also checkmate.
