Stephen Hendry's 4-0 victory over Ali Carter to reach the Brazil Masters semi-finals proves that he can still play the game, it is just inconsistency and concentration that have been letting him down of late.
To 2-0, Hendry played really well. Carter's head went in the third when he potted a red, attempted to roll up to the brown, left it short and, put back in, got down and lashed the cue ball off the side cushion and into the reds. That was 3-0.
His poise didn't really return and Hendry gratefully took advantage to sail through by way of whitewash.
Apart from winning the 110sport Legends event in Glenrothes two years ago, Hendry has not been in a final since the 2006 UK Championship.
He needs to beat Shaun Murphy to remedy that, no easy task but not an impossibility either.
The other semi-final is a repeat of the 2006 world final between Graeme Dott and Peter Ebdon.
That was a right old grind of course and Ebdon seems to be in the mood for similar this week but Dott played well in beating Brazilian wildcard Igor Figueiredo in the previous round and can contend with whatever is thrown at him.
