WHAT HAPPENED Move Played: Qh6 Black played 25...Qh6. By moving the queen from c6 to h6 the defender of the c5‑knight was removed. The immediate consequence is that the white rook on e5 now attacks the undefended knight on c5. White’s threats (b5, c5, f7) include the concrete tactical shot 26.Rxc5, winning a piece. Additionally the move leaves the g7 pawn undefended (as shown in the ‘undefended_black’ list) and abandons the pressure on f3, so Black’s own threats evaporate. WHY IT'S BETTER Engine suggested: Ne6 The engine’s recommendation 25...Ne6 keeps the material balance. The knight jumps to e6, covering the c5 square and also reinforcing the d4–f4 diagonal, while the queen stays on c6 to maintain the pressure on f3. After 25...Ne6 Black still threatens …Qxf3 and retains a solid defensive net around the king. In contrast, 25...Qh6 concedes the knight and gives White a free winning tactic, which is why the engine rates it as a blunder. KEY PRINCIPLE Never abandon the defence of a piece without a concrete gain: If a piece is currently defended, moving the defender must create at least equal counter‑play. Here the queen left the c5‑knight undefended, allowing a simple capture. Keeping the defender (or finding a replacement) is essential. |
