Solution & explanation

Main line

28. Qxa8+ Rxa8 29. Rxa8+ Qb8 30. Rxb8#

Why it works

  • Great move! queen to a8 keeps the pressure (#2).
  • Well found: rook to a8 (#1).
  • Strong! rook to b8 is the sharp choice (#).
  • The line ends in a forced mate in 3.
  • If instead Rxa8, then Rxa8+ and you stay on top.
