Black, Adjacent

Black, king on b8 hugging the rook on a8 — and you're ordering kingside, to the opposite edge! The king faces a dash b8 → g8 across the whole rank, and my sister on h8 will meet him on f8. A double trap for the beginner: the unfamiliar colour AND the adjacent rook throwing you off — but you're a seasoned fighter by now. King — onto the rook h8, charge!
