White to move — find the best continuation

Solution & explanation

Main line

19. Ra8+ Rb8 20. Rxb8+ Kxb8 21. Qb7#

Why it works

  • Great move! rook to a8 keeps the pressure (#2).
  • Well found: rook to b8 (#1).
  • Strong! queen to b7 is the sharp choice (#).
  • The line ends in a forced mate in 3.
  • If instead Rb8, then Rxb8+ and you win the rook.
