Black chose 36...f5, pushing the pawn from f6 to f5. The move does not create any immediate threats; the only listed black threat is the distant e2 square, which remains blocked by the black knight on e4. By playing f5, Black leaves the h‑pawn on h4 untouched and allows White’s king on b4, rook on e1, and pawn on h2 to stay completely undefended. No material is won and Black’s own pieces (the rooks on e8 and c2, the king on g7) remain undefended.

The engine’s top move 36...h3 generates a concrete, unstoppable threat. The pawn march h4‑h3 attacks the white pawn on h2 and forces the white king to walk from b4 toward the queenside (e.g., 37.Kb3). After the king is forced to defend, Black can continue with ...h2 and promote, or use the rook on c2 to infiltrate. In contrast, 36...f5 merely reshuffles a pawn and does not exploit the far‑advanced white king or the weak h‑pawn. The h‑pawn push creates a passed pawn and forces a defensive response, whereas f5 leaves Black’s position static and gives White time to consolidate.

Create Immediate, Unstoppable Threats: When you have a passed pawn or a distant weakness, prioritize moves that force the opponent to react (e.g., advancing a pawn that attacks a vulnerable piece). A speculative pawn break that does not generate threats (like ...f5 here) wastes tempo and lets the opponent keep the initiative.
