The rematch rule

FIDE's regulations of the era let a dethroned champion demand a return match a year later without re-qualifying. The clause came to be nicknamed the "Botvinnik rule" precisely because Botvinnik, twice deposed, twice used it to win the title straight back. Between matches he prepared with his trademark scientific rigour, this time to reverse the verdict of 1957.

It worked immediately.

Three wins out of the gate

Botvinnik won the first three games and never surrendered the lead. The match was not flawless — in the fifteenth game, absorbed in a winning position, he astonishingly forfeited on time — but he kept his composure, and a draw in the twenty-third game secured a 12½–10½ victory and his second reign (+7−5=11).

Smyslov's brief championship was over; the two would never meet for the title again.
