Re: Selby
It is of course but once in it's just you. The curling one they get a go to change the game between all of yours. They can at any point smash one of yours out the way. It's a significant part on the performance of your opponent as it is you.
Just for the sake of pedantry i found one ( with help of Google of course)
A condor in golf .... four under par at one hole ..... so you'd have to hit a hole in one on a 5 par hole or 2-shot a par 6
Only recorded once in a major tournament and 6 times ever .. five times on a par 5 and once on a par 6 ... though the one on a par 6 seems to have had a shot land on a path and travel hundreds of yards ... [www.nationalclubgolfer.com]
however .. all sound like a fluke to me ... so i'm going with the 147 being the most difficult
