Small nitpick: you could replace “no funny business with pawns promoted to Rook” with “and are on their home squares” as there’s no way for a promoted pawn to get to a rook’s home square without moving ;)
- toast0 2y agoWell... if you want to get into really funny business, white could promote to a black Rook on its home square (not valid with current FIDE rules, but older rule sets weren't always specific about the color of the piece promoted to). I don't think you should castle with that Rook, but maybe? I guess something about being on the squares since the beginning of the game.
- scott_w 2y agoYeah but now you’re following a path the rules don’t allow so it’s not really necessary :-p
