You played Na4, relocating the knight from b6 to a4. The move does not challenge White’s pressure on the queenside, leaves the pawn on b4 untouched, and still offers no defence for the vulnerable e7 pawn. White’s threats on d7, f7 and g6 remain, while Black’s own threats (b2, c4, e4, h5) are unchanged.

The engine’s 20...a5 pushes the a6 pawn to a5, immediately attacking the b4 pawn and forcing White to address the queenside weakness. By advancing the a‑pawn, Black creates counter‑play, opens the a‑file for the rook, and reduces White’s ability to exploit the b4 pawn. This active pawn break is far more effective than a passive knight hop that does not improve Black’s defensive posture.

Create counter‑play on the opponent’s weaknesses: When under pressure, push a pawn or activate a piece that directly attacks the opponent’s vulnerable target rather than moving pieces to idle squares.

You moved the bishop from b2 to f6 (Bf6). This maneuver does nothing to stop White’s looming tactical strike, most notably the forced 26.Qxg6+ which wins material and opens a decisive attack on the Black king. The move also leaves the a4 knight and the pawn structure untouched, and the e7 pawn remains undefended.

No engine move is listed because the position is already lost; the priority is to meet the immediate threat. Any move that does not address the forced 26.Qxg6+ allows White to seize the initiative and convert the attack. Bf6 is a point of no return because it ignores the critical capture on g6, leaving Black with no viable defense.

Never ignore a direct tactical threat: When the opponent has a forcing capture that wins material or mates, your first duty is to neutralise that threat, even if it means sacrificing material elsewhere.

You played Rb8, sliding the rook from f8 to b8. The move does not defend any of Black’s critical weaknesses (a6, c3, c5, h4) and leaves the bishop on h4 completely undefended. White’s threats on a6, c3, c5 and g6 remain fully active, while Black’s only threat is the modest e4 push.

The engine recommends 32...e6, a pawn move that attacks the white pawn on d5, reduces White’s pressure on c5, and opens lines for the bishop on f5 to help defend the h4 bishop. By playing ...e6 Black directly confronts the most dangerous white pawn (d5) and creates counter‑play, whereas Rb8 is a purely cosmetic rook shift that does not improve the defensive situation.

Defend critical weaknesses before making side‑ways moves: When key pawns or pieces are under attack, prioritize moves that shore up those points; peripheral rook maneuvers are ineffective if the king’s safety and material balance are already compromised.
