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

White to move — find the best continuation

Solution & explanation

Main line

25. axb3 Qxe4+ 26. Rxe4 h6 27. Qc7#

Why it works

  • Great move! pawn to b3 keeps the pressure (#2).
  • Spot on — rook to e4 (#1).
  • Precise: queen to c7 is the top choice (#).
  • The line ends in a forced mate in 3.
  • If instead Qxe4+, then Rxe4 and you win the queen.
