Which major would you most like to win? A common question from golf writers to players. Answers, of course, vary, but it's not surprising to hear most European-based players swing toward the Open Championship - particularly when it's at St Andrews, the home of golf.
Martin Kaymer had two major championship titles to his name before he hit 30. He edged out Bubba Watson at the 2010 PGA Championship, but suffered a dip in form largely related to attempts to adjust his swing in a bid to arrest his poor record at The Masters. It worked, to an extent. Four missed cuts were followed by three top-50 finishes, but he suffered elsewhere.
A return to his old routine sparked a bit of the old magic that had seen Kaymer force his way to world No.1 and that major breakthrough at Whistling Straits. He announced his return in spectacular fashion, taking the Players Championship title before romping home at the U.S. Open - becoming the first player to win the PGA Tour's flagship event and national open in the same season.
"My focus is the Open," Kaymer admitted ahead of the Masters in April. And it showed. He slumped to another missed cut at Augusta - a fifth in eight years - as well as his title defence at Chambers Bay.
But Scotland is a happy hunting ground for the 30-year-old German. He won the fifth and eighth of his 11 European Tour trophies at the Scottish Open and Dunhill Links Championship respectively, while he was a vital cog in Paul McGinley's expertly engineered Ryder Cup triumph at Gleneagles last year.
And it all serves as a frank reminder to the St Andrews field of the threat Kaymer poses around the famous Old Course this week.
"It is my favourite course in the world," he says. "The whole atmosphere around St Andrews is just so pure, so natural. That is the place where I feel the most comfortable.
"I have won on that course [at the Dunhill Links] and in 2010 I finished seventh at the Open there."
Kaymer opted not to play in the Scottish Open last week, choosing instead to "chill out", as he calls it, and "watch a couple of days of tennis at Wimbledon". He will practice at nearby Kingsbarns and Carnoustie to get used to the conditions.
"I really want to start off the week fairly calm and enjoy it," he adds. "I have thought about the Open since January or February because I think I have a chance. I just need to make sure that my excitement is not in my way. It is important you try to lower that excitement and let things fall into place.
"For me, it is the most important week this year."
