White to move — find the best continuation

Solution & explanation

Main line

19. Rxc3+ Qc6 20. Bxc6 Re8+ 21. Be4#

Why it works

  • Best move. rook to c3 is exactly what the engine plays (#2).
  • Spot on — bishop to c6 (#1).
  • Precise: bishop to e4 is the top choice (#).
  • The line ends in a forced mate in 3.
  • If instead Qc6, then Bxc6 and you win the queen.
