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

White to move — find the best continuation

Solution & explanation

Main line

28. bxc7+ Kc8 29. Ra8+ Kb7 30. Qa7#

Why it works

  • Best move. pawn to c7 is exactly what the engine plays (#2).
  • Spot on — rook to a8 (#1).
  • Precise: queen to a7 is the top choice (#).
  • The line ends in a forced mate in 3.
  • If instead Kc8, then Ra8+ and you win the bishop.
