White to move — find the best continuation

Solution & explanation

Main line

17. Ba4+ Bd7 18. Bxd7+ Kxd7 19. Nb3+ Qd5 20. Rxd5+

Why it works

  • Great move! bishop to a4 keeps the pressure (+5.3).
  • Well found: bishop to d7 (+5.3).
  • Strong! knight to b3 is the sharp choice (+5.4).
  • Best move. rook to d5 is exactly what the engine plays (+5.6).
  • You win a piece — the queen.
  • If instead Bd7, then Bxd7+ and you win the bishop.
