Solution & explanation

Main line

31. Rxa7 g4 32. Qc5 g3 33. Qxe7+ Kg6 34. Qg7#

Why it works

  • Best move. rook to a7 is exactly what the engine plays (#3).
  • queen to c5 develops smoothly.
  • Precise: queen to e7 is the top choice (#1).
  • Best move. queen to g7 is exactly what the engine plays (#).
  • The line ends in a forced mate in 4.
  • If instead g4, then Qc5 and you stay on top.
