Interregnum

The only official interregnum in the reigns of the world chess champions was that between the death of Alekhine in 1946 and the accession of Botvinnik in 1948. There is, however, an unofficial interregnum which occurred when Bobby Fischer won the world title in 1972 but did not play a serious game of chess as champion and forfeited the title without play to Karpov in 1975. At this point, step forward Mikhail Tal. According to statistician John Ellis in the August issue of the British Chess Magazine, it was Tal who filled the void created by Fischer’s disappearance. From July 1972 to April 1973, according to the BCM, Tal played a record 86 consecutive games without a loss, comprising 47 wins and 39 draws. Then he improved on this record between October 1973 and October 1974 when he played a further 95 consecutive games, again without loss, scoring 46 wins and 49 draws.
