Chess960 twist: use the unusual starting setup of the pieces.

White to move — find the best continuation

Solution & explanation

Main line

9. Qxb4 O-O 10. Qd6 Nc7 11. Bg5

Why it works

  • Great move! queen to b4 keeps the pressure (+4.7).
  • queen to d6 develops smoothly.
  • A natural move: bishop to g5.
  • You win a piece — the bishop.
  • If instead O-O, then Qd6 and you win the bishop.
