Where does the black king move?
It can’t move but it’s not in check so that makes it a stalemate. I am a Chess Expert™️ so you can probably believe me
I didn't know that rule 😂 Then the Rook must turn into a Castle forcing the Black King to move to G7. White Castle F1 moves up to F7 for the checkmate. https://i.nostr.build/ttgCK2iQ2Qcd88Mb.jpg
