I think most golfers don't think about subtle strategy, let's put it that way, if your can't break a 100, your only strategy is hit the ball as good as you can then to avoid lakes, bunkers etc...
But if the same players keeps getting better, he'll start to understand more relevant stuff on the course, he'll start digging deeper into the strategy of the course.
I'll mention that for example, put Tiger Woods and Bill Waboe (a player who plays 95 on a good day) on the 14th fairway at Augusta at around 150 yards.
Bill Waboe looks at the hole and thinks, no bunkers or lakes, all fairway (before Fazio) and the pin is on the right side of the green, easy shot, just a smooth 6-iron.
Then Tiger from the same spot is thinking, OK the false front is a big problem, 146 to carry it, plus I must hit a shot with not a lot of spin, then at the hole there a left to right slope, I could also use the back stop long and left and bring the ball back... short and right is bogey, not a simple shot but an 8-iron soft cut will get the job done...
Of course Bill will be short right and make double but the point is, he was just thinking to hit the ball...
Subtle strategy is mainly for players who control their game, could be a 65 year old guy who hits the ball 150 in the air... as long as you know what you are doing... A course with Subtle strategy will force you to improve.
