I've had a 78 hitting every green. I've played a bogey free round 70 hitting 3/18... My only birdie way a 50 feet chip-in.
But on a good game it's pretty simple.
Have to stay out of trouble on my drive. (Knowing where to miss)
Have to hit decent irons on the green or near miss. (Knowing where to miss)
On those near miss I have to chip very close. Because I'm not that good at making 5'+ footers for par.
If I do all this I'll play a 74 or better.
On a very low score day If I can play to my strenght I drive very well and setup alot of 125 to 75 yards shot. From there, I'll get down in 3 most of the time... and in 2 more than in 4.
