Korchnoi knew the rule, he was just suffering from the stress and blew a synapse.

Unless, of course, Sam comes along SEVEN minutes later and blabs the answer. 😠

Not to worry, it doesn't look like anyone cared.

In 1972 the rules for castling were changed. A requirement was added that the King and Rook must be on the same RANK. It would seem the requirement that neither King nor the Rook involved has moved would ensure they were on the same rank (original squares). Why was this change necessary? Let people think about it and I'll post the answer later today.

Because first it was legal to castle with promoted rooks.
