Ross Fisher continued to take on the mighty Fancourt links with an impressive second round of 70 to hold the outright lead at the South African Open.
He is now five shots clear of his nearest rival, Retief Goosen, with his eight-under par total.
Defending champion Tim Clark was tied for the lead with Fisher after the first day but stumbled to a 78 .
The course is proving to be so difficult that Fisher will have to put in maximum concentration if he is to hold onto his lead.
Second placed Goosen critised the course saying that the pin positions and bunkers were "ridiculous"
