- Superior putting
- Getting up and down around the greens
- Avoiding OB, lost balls and water hazards
It really just comes down to these factors, and that second one is very largely a factor of the first.
The course doesn't make that much of a difference to me, typically. I'm a pretty steady player, mostly pars and bogeys so what can really swing my score is making some putts for birdie or par saves, or those rounds where I'm really crooked and piling up penalty shots, so that double+ becomes a factor.
That said, I have always felt I'm pretty good at reading the architecture, even if it's in a very basic way. It's always weird to play with people who hit driver off of every tee, even if you tell them the fairway runs around, narrows, or whatever. Knowing where to miss is another key and even on a course I'm not super familiar with I probably have a bit of an advantage since I spend the time to study course aerials, yardage books, etc even before I play--that can help you to know that maybe you really don't want to miss right on a hole where it's a little blind, for example.
