Stephen Hendry is snooker's greatest ever player and greatest ever champion and demonstrated that the desire for further success burns deep within him at the Crucible last night.
But his match against Mark Williams at the Betfred.com World Championship also proved that, in sport, the unexpected can play a major part.
We all studied the form and made predictions based on it but nobody would have thought that Williams would have problems with his tip.
It played on his mind from the start of the final session and, at the end of the 12th frame, he asked the referee, Alan Chamberlain, if he could take a time-out to replace it.
The rule is that the tip has to have come off or at least be about to come off for this to happen.
Very sportingly, Hendry said he had no problem taking an early interval.
But as it transpired, the new tip - which will always take time to bed in - did for Williams. He fell apart as a succession of misses handed Hendry the chances he needed to win his 65fh match from the 81 he has played in 24 appearances at the Crucible.
This win clearly meant a lot to him.
This was no surprise. Great champions relish only one thing: winning.
And Hendry still believes he is a winner.
