White to move — find the best continuation

Solution & explanation

Main line

20. Ba6+ Kd8 21. O-O-O+ Nd5 22. Rxd5+

Why it works

  • Great move! bishop to a6 keeps the pressure (#5).
  • Spot on — king to c1 (#4).
  • Precise: rook to d5 is the top choice (#3).
  • You win a piece — the knight.
  • If instead Kd8, then O-O-O+ and you stay on top.
