Billy Horschel said his game plan would stay the same despite taking a two-shot lead at the Tour Championship on Friday.
The American carded another four-under-par 66 in Atlanta to be ahead of countryman Chris Kirk, Northern Irish world number one Rory McIlroy and Australian Jason Day.
Despite closing in on a $10million FedEx Cup win, Horschel said his approach would remain unchanged.
"We've got a game plan that we came up with and we're going to stick to it," he told a news conference.
"We have some information from the way the course is playing before we tee off and take that into account and we're going to be aggressive at the holes.
"On the holes where par is a good score, we're just going to make sure that we're in the right place to make par.
"There's nothing different, not thinking different, just doing my thing and whatever everybody else wants to do out there I'm fine with."
Horschel holed six birdies and two bogeys during his second round and said his iron shots let him down, but he was pleased overall.
"I drove the ball really well today, got off to a good start, two under through three," he said.
"Unfortunately, I gave some shots back and five and seven with some easy chips and then I played pretty solid coming in.
"I probably could have hit some better iron shots but I'm happy with the way I played today.
"Like I said yesterday, I'll take three more 66s and see where that puts me, and today I'll take two more 66s and see where the puts me on Sunday."
