Justin Thomas: “It changes with the day, it really does. Take 14 at St Andrews… if you get that hole with the wind in and off the left, that all of a sudden becomes very challenging. But I think 17 is the hardest in my eyes. If it’s downwind and you have a short club in, it’s going to be hard to hold the fairway. And if you do, it’s going to be really hard to hold the green. And if it’s into the wind, you’re just going to have a long club and you can’t carry as much.”

Padraig Harrington: “It’s 17, the ‘Road Hole’, because of the pain it’s caused so many people over the years. The idea you can play 70 holes at The Open and you’re still worried about the 71st hole… You can’t win at St Andrews until you’ve played the 17th. It’s intimidating.”

Richie Ramsay: “I would have said 14 at St Andrews a few years ago, but now I think 17. It’s right at the end of your round but still has the power to cause catastrophe. If you misjudge something, get your angles wrong, then you can take a double in a heartbeat. If you play a fantastic shot, a three is out there. If you’re chasing, it gives you hope, and if you’re leading your heart will race coming down there. It’s a brilliant hole for spectators, and it tests us to the max.”

Alex Noren: “I would say the one that gets your attention the most is 17 at St Andrews. It’s so good, and it plays so tough. You can play it towards the 18th tee box or to the right. It’s the toughest tee shot in the world. If you put it behind the bunker, you have to hit the perfect flight, the perfect shape, into a 10-foot area.”

Paul McGinley: “My favourite course is Turnberry but you’d probably have to say one of the holes at St Andrews. Probably the 17th because of all the history on it. It depends on the wind but you’re always happy to take a four.”

Matt Fitzpatrick: “I’d have to go with one at Turnberry. I love it there. Maybe the ninth, the par three with the water.”
