Qc6 Kd8 ...[text shortened]... construct games like the above without a rook on d1, in fact it is a lot easier, in both cases.
    Have you read the posts in this thread explaining Dead Reckoning? This rule eliminates the PG with lost castling rights, for Black could not play KxR at the end.

    In move 53 for b), after White moves Re3+, the position is already dead, so black can make no further moves.

    And again, if the rook weren't on d1, then you'd be right in that games could be constructed in which White keeps his castling rights, and in which he loses them. But with the rook there, only keeping them yields a legal position.

    EDIT: SwissGambit, you posted while I was typing again! You're good.

    Here's an article by Andrew Buchanan on the subject.

    You are right (as usual), I didn't take account of that point.
