Arseniy_Nesterov vs magnuscarlsen

Black responded to White's 11.f4 with 11...gxf4, capturing the pawn that had just advanced to f4. The capture eliminates White's central pawn, opens the g‑file for Black's rook, and places a pawn on f4 that attacks e3 and g3. After the exchange, Black still has the same material but has removed a key pawn that was supporting White's central break and the upcoming threats of b5, c5, and g5. The move also neutralises White's immediate pressure on the kingside and keeps Black's pieces (especially the bishop on g7) safe, despite the fact that Black's b7‑bishop and g7‑bishop remain temporarily undefended.

The engine rates 11...gxf4 as the optimal continuation because it converts White's pawn thrust into a concrete gain. By taking on f4 Black: (1) removes a pawn that could later support a central or kingside attack; (2) creates a passed pawn on the f‑file that can become a future tactical weapon; (3) opens the g‑file for possible rook activity; and (4) eliminates the immediate threat of White's pawn storm (b5, c5, g5). Any alternative, such as a quiet move, would allow White to keep the pawn on f4, maintain central space, and accelerate the pawn storm, giving White a dangerous initiative. The engine’s suggested continuation 12.Bg1 (for White) shows that after the capture Black still retains a solid position with no immediate tactical liabilities.

Capture advancing pawns that create central or kingside threats: When an opponent pushes a pawn that strengthens their center or attack, taking it removes that momentum, opens lines for your pieces, and can turn a defensive move into a strategic advantage.
