White to move — find the best continuation

Solution & explanation

Main line

29. Bxb6+ Nxb6 30. Qxb6+ Kc8 31. Qc7#

Why it works

  • Great move! bishop to b6 keeps the pressure (#2).
  • Well found: queen to b6 (#1).
  • Precise: queen to c7 is the top choice (#).
  • The line ends in a forced mate in 3.
  • If instead Nxb6, then Qxb6+ and you win the queen.
