The Masters could best be described as four days of the world's toughest golf. So what does it take to win the Green Jacket?

"Skill, definitely skill," Aysegul Siranli said.

"Little bit of luck, but mostly talent," Beth Holland said.

"Getting that ball up or down or two-putting from an awkward place, that's skill," Bob Macmillan said.

The world's best are competing to master the National. But, what does it take to conquer the course? Four days, 72 holes and most fans say a whole lot of skill.

"It must be the skill for sure," Siranli said.

Golf fans will tell you it takes more than skill to master the greens here at Augusta National.

"To play this golf course, you got to have a little bit of luck," Mike Power said.

"I think to win this, you have to have luck because they're all skilled players," Craig Barry said.

So which is it? Some people say a combination of both.

"70-30. Skill 70, luck 30," Power said.

"Pure talent, that's it and a little touch of luck thrown in. Talent carries you the whole way," Holland said.

Golf Digest rated Augusta National as one of the top 10 most difficult golf courses in the World.
