It is important to start with these disclaimers:
I love links golf. I love playing it, I love watching it, and I will always defend it as a the way golf was meant to be played against everybody who doesn't like it.
I love the Irish culture and the Irish landscape. All people from Ireland I have met were extremely pleasant and likeable.
So please, I don't want to draw the ire of this entire nation at me.
That being said:
I don't understand the glowingly positive things people said about Portrush in all of the previews, especially that it is a fairer test than many other Open venues. I can't remember ever seeing so many great shots ending up with terrible results and so many mediocre shots with good results. In my view, this is caused by the way the greens are built with their false fronts and upturned saucer features.
And after watching two full rounds, I still don't recognise many of the holes immediately, like I usually do on almost all other Open courses. The 4th, 5th, the 16th and the 18th are the only exceptions.
I also ask myself how this course is even playable without thousands of spectators and hundreds of spotters and marshals.
