On page 6 of “The Chess Beat” by Larry Evans:
To the surprise of nobody, young Karpov romped over his countryman Lev Polugayevsky 5 1/2 – 2 1/2 [In the 1974 Candidates’ quarter-final.]
A rather peculiar thing to claim, particularly since on the very next page Evans writes “[Bobby] Fischer told friends he was surprised that Karpov beat Polugayevsky”.
