You retreated the knight with 28.Nf6, moving it back to its original square. The move does not create any new threats; Black still threatens …Nd3, which could fork White's queen‑side pawns and the rook on d1. White's pawn on d5 remains undefended, and the knight on f6 does little to stop Black's upcoming fork.

The engine's alternative 28.Be2 develops the bishop, reinforces the d4‑square, and prepares to meet …Nd3 with a solid defence (e.g., Bc4‑e2). By playing Nf6 you waste a tempo and allow Black's knight to jump to d3 with a fork, whereas Be2 keeps the position cohesive and limits Black's tactical options.

Avoid unnecessary retreats – Every move should either create a threat or improve your position; stepping back without purpose gives the opponent time to generate counterplay.

You played 33.Rf8, sliding the rook away from the active d8‑file. This move abandons the pressure on Black's f7‑pawn and allows Black's knight on f3 to hop to g1 with a fork, winning material or delivering a decisive attack. White's bishop on c4 still eyes f7, but the rook no longer supports the attack.

The engine recommends 33.Bd5, keeping the bishop on the diagonal that attacks f7 and simultaneously shielding the rook on d8 from tactical ideas. Bd5 forces Black to defend the pawn, preserving White's winning chances. Rf8, by contrast, hands Black the initiative and leads to a losing position.

Maintain the momentum of an attack – When you have a concrete threat, keep the pieces that generate it; moving them away often lets the opponent seize the initiative.

You chose 58.Rf5, a passive rook lift that does not improve your pawn structure or king safety. The move leaves the rook on the a‑file free to infiltrate, and White's only pawn weakness (b4) remains undefended. No new threats are created, and Black's rook on a1 can soon dominate the seventh rank.

The engine's move 58.c4 pushes the passed pawn, gaining space and restricting Black's rook on a1. The pawn advance also creates a potential queening threat and forces Black to respond, buying White time. Rf5 does nothing to stop Black's plans, while c4 actively reshapes the endgame in White's favour.

Create passed pawns and restrict opponent's pieces in the endgame – A pawn push that gains space is often stronger than an idle rook move.

You played 68.Ke4, stepping the king into the line of Black's advancing b‑pawn. After Ke4, Black can push …b4 with tempo, creating a passed pawn and opening lines for the rook on d6. White's king becomes a target, and the pawn on b4 becomes a decisive passer.

The engine suggests 68.b5+! Kb6, a checking pawn advance that forces the black king to move, gains a tempo, and immediately creates a passed pawn on the b‑file. This move not only avoids the king walk into danger but also turns the pawn structure to White's advantage. Ke4 forfeits the initiative and hands Black a winning pawn.

Never walk your king into the path of an opponent's pawn – Use checks or tempo‑gaining moves to keep the opponent's pawn from advancing and to create your own passed pawn.
