Is there luck in chess?

From The Master Game, Book 2, Jeremy James and William Hartston (1981). London: BBC.
'Chess,' said the Dutch grandmaster, Jan Hein Donner, 'is as much a game of chance as blackjack; or tossing cards into a top hat.' There was a pained silence, then a polite babel of disagreement: it was a game of the utmost skill; a conflict between disciplined minds in which victory would inexorably go to the more perceptive, the more analytical player; a duel of the intellect in which luck played no part. Donner shrugged, lit another cigarette and said: 'Believe that if you like.' Bent Larsen smiled the smile of a man who had heard his friend air such iconoclastic arguments in the past but was quite happy to contest them again, when the score of the fifth game of the World Championship match between Karpov and Korchnoi was brought in. Both men pulled out of their inside pockets the wallet sets all grandmasters seem to carry at all times and began to skim through the moves.

It happened that the teleprinter tape had been torn off after Karpov's 54th move as Black [...]. They studied the position for a few moments, mated Karpov in four moves and were surprised when another whole sheet of moves was brought from the teleprinter.

When they saw Korchnoi's 55th move - Be4+ - Larsen's eyebrows went up.

'There you are,' Donner said, quietly and without triumph as though some self-evident truth had been revealed, 'pure luck'.
