White to move — find the best continuation

Solution & explanation

Main line

12. Rxf8+ Nxf8 13. Qxg7 O-O-O 14. Qxg5

Why it works

  • Brilliant! The rook on f8 is a sacrifice that works — you stand better (+2.0).
  • Well found: queen to g7 (+2.0).
  • Precise: queen to g5 is the top choice (+2.2).
  • You win a piece — the rook.
  • If instead Nxf8, then Qxg7 and you stay on top.
