South African spinner Johan Botha is relishing the challenge of quelling Kevin Pietersen's switch-hitting tactics.
Botha has yet to face England captain Pietersen in a competitive match but has been scheming ways to counter any changes of stance at the crease.
Pietersen brought the stroke to attention with two huge sixes, after reverting to a left-hand grip, off New Zealand medium-pacer Scott Styris in the English summer's first NatWest Series.
Since then, South Africa's management has been particularly impressed in the Test series with how Pietersen's ingenuity has made them alter their field settings.
Before the NatWest campaign opener at Headingley on Friday, Botha said: "Obviously you have to find a way to bowl some dots against him and build a bit of pressure, because he is one of the world's best if not the best at the moment.
"He has got all the shots and new ones. I see it as a challenge because no one else out there does it, so I would like to see what I do if he does it.
"We have had a few chats, and some of the senior guys have an idea what I should do.
"If he moves late you cannot do anything if the ball has already left your hand.
"If he does move early you maybe could pull out, but I suppose it is also a good opportunity for a wicket if you get it right.
"If he is totally turning around then his head is moving.
"But you have to acknowledge he has done it well so far: I have seen him five to 10 times, and he has never failed."
Botha, 26, is one of the Proteas' limited-overs specialists and captained the side to victory over England Lions in Leicester when Graeme Smith rested his troublesome back last week.
Although South Africa is rated second in the world in limited-overs cricket, it tripped up against the Lions in Derby - and England also gained momentum with a win in the final Test, which reduced series defeat to 2-1.
"The first two games are going to be important," Botha insisted.
"If we can set it up early and take a lead I am sure the confidence should take us through to the end, and we can win the series."
Wet weather - which wiped out Wednesday's scheduled Twenty20 international at the Riverside - has frustrated the South Africans since they swapped whites for their green limited-overs kit.
They plan to train outdoors in Leeds on Thursday, however - and although all-rounder Albie Morkel (shoulder) is not expected to be fit for the series opener, they are hoping his fast-bowling brother Morne Morkel (side strain) will be available.
