White to move — find the best continuation

Solution & explanation

Main line

8. Qxa8 Qh4+ 9. g3 Qxg4 10. Qa3

Why it works

  • Brilliant! The queen on a8 is a sacrifice that works — you stand better (+2.7).
  • Spot on — pawn to g3 (+2.6).
  • A natural move: queen to a3.
  • You reach a winning position (+2.5).
  • If instead Qh4+, then g3 and you win the rook.
