Black to move — find the best continuation

Solution & explanation

Main line

38... Bb1+ 39. Ka1 Bc2+ 40. Ka2 Bb3#

Why it works

  • Great move! bishop to b1 keeps the pressure (#2).
  • Spot on — bishop to c2 (#1).
  • Precise: bishop to b3 is the top choice (#).
  • The line ends in a forced mate in 3.
  • If instead Ka1, then Bc2+ and you stay on top.
