Solution & explanation

Main line

39... Rxb3+ 40. Kxb3 Qb1+ 41. Ka3 Qb2#

  • Great move! rook to b3 keeps the pressure (#2).
  • Well found: queen to b1 (#1).
  • Strong! queen to b2 is the sharp choice (#).
  • The line ends in a forced mate in 3.
  • If instead Kxb3, then Qb1+ and you stay on top.
