WORLD No. 1 Park In Bee is primed for one of her toughest battles yet as she headlines the field at the HSBC Women's Champions golf tournament in Singapore this week.

The South Korean, who won three of the five Majors last year, expects a keen fight at the Sentosa Golf Club as her rivals seek to wrest the top spot which she has held for 45 straight weeks.

The California resident, 25, said at a media conference on Tuesday: "The Serapong course requires you to be extremely precise with bunkers and water at every turn but if you want to be the best, you have to embrace a challenge like this.

"As ever, this is a world-class field and I'll be going all out to win the trophy."

A total of 58 of the planet's top 60 female golfers are in town, including New Zealand prodigy Lydia Ko and fan favourite Paula Creamer of the United States.

Teenager Amanda Tan - the tournament's youngest player at age 14 - will represent Singapore at the US$1.4 million showpiece, which runs from Thursday to Sunday.

World No. 2 Suzanne Petersen already has a plan in mind to tackle Serapong, which is known for its unforgiving rough, skinny fairways and quick greens.

The Norwegian said: "You got to play smart and take advantage of the pin positions - some of the par-fives are reachable. Finding the right spots on the fairway is crucial or you'll get blocked out.

Creamer is hoping that the course stays true to its reputation and that the fans will have much to cheer about this week.

She said: "The greens here are among the best we see on the LPGA Tour - let's hope we give fans something to remember for a long time to come."
