Chess960 twist: use the unusual starting setup of the pieces.

White to move — find the best continuation

Solution & explanation

Main line

36. Rb1+ Bb2 37. Rxb2+ Ka7 38. Qa4#

Why it works

  • Best move. rook to b1 is exactly what the engine plays (#2).
  • Spot on — rook to b2 (#1).
  • Precise: queen to a4 is the top choice (#).
  • The line ends in a forced mate in 3.
  • If instead Bb2, then Rxb2+ and you win the bishop.
