White to move — find the best continuation

Solution & explanation

Main line

20. Rxg7+ Kf8 21. Rg3+ Kf7 22. Qh7#

Why it works

  • Best move. rook to g7 is exactly what the engine plays (#2).
  • Spot on — rook to g3 (#1).
  • Precise: queen to h7 is the top choice (#).
  • The line ends in a forced mate in 3.
  • If instead Kf8, then Rg3+ and you stay on top.
