The top-ranked Tseng tops the LPGA money list and is full of confidence heading into the year's fourth and final major after her victory at the LPGA Championship last month.
"There are so many ways you can play this course, you can be aggressive, you can be safe, you can hit driver, you can hit iron," the 22-year-old Taiwanese player said. "You've just got to use your imagination and hit creative shots."
Last year at Royal Birkdale Tseng led from the start, with 68s in the first three rounds before closing with a 73 to clinch victory.
"I love the links courses. I'm so excited to be here and I just can't wait to go out tomorrow," Tseng said. "It's a very, very fun course for me. I have so many good memories of the British Open, so I'm just so excited to be here."
Miyazato, winner of the Evian Masters in Paris last week, will be one of the favorites alongside Tseng to lift the title on Sunday. The sixth-ranked Miyazato said she would be ready for the challenge of Carnoustie.
"This is the British Open. The wind is going to pick up and it will be raining, I'm pretty sure," Miyazato said. "I feel very confident and I feel comfortable. You can't control the wind and the rain you just have to play the golf course as it is on the day."
Michelle Wie, whose sixth-place finish at this year's Kraft Nabisco Championship was her best performance at a major since 2006, said she is still working on mastering her long putter coming into Carnoustie.
"I decided to make the change the week after the Open back home," Wie said. "I'm obviously just trying it out, different grips and different ways to do it. I thought it was time for a change. I'm a pretty tall person so I thought I would give it a try.
"This is a pretty unique golf course. The greens are pretty bumpy and slopey, which make it difficult. So it will be a challenge for me this week."
Paula Creamer traveled to Carnoustie before the Evian event for a couple of practice rounds.
"I had a local caddie, the club champion, and played with the pro and I really learned a lot," the 2010 U.S. Open champion said. "I love links golf, this tournament and this golf course. I feel I can play well here.
"I like the challenge, in fact the harder the better. I believe it's going to rain tomorrow. I want it to be blowing and bouncing during the tournament."
"I played a lot here as an amateur ... so I know it very well," said Matthew, who won at Royal Lytham two years ago, 10 weeks after giving birth to her second daughter and three weeks before her 40th birthday.
"It's a tough test, but like any links course it depends on the wind. If there's no wind, none of them are overly difficult," she said. "If you can drive the ball well, you'll have a lot of birdie chances out there. Keep out of the bunkers and you've got a great chance."
Melissa Reid of England won the Dutch Open in June and is fourth on the European Tour money list.
"I certainly feel my game is more mature than it was a year ago. My swing feels a lot better, and I feel very calm this week," Reid said. "This is definitely one of the top five courses I have played and I feel quite settled here."
