The trees pretty much take away the safe hyzer line, leaving you with the lazer beam chance at an ace run. But you'll lose strokes if you don't deuce. Stable putter or mid straight at it, but not too fast.
You need controlled distance off the tee here, where the best position to be in would be the far side of the ravine, looking straight up the slope to the pin for the possible deuce. But don't go out of control, because tree kicks turn this into a four or five real quick.
The tight fairway line aims left of the basket, so most rhbh folks pull out an understable mid or putter, and try to thread through & glide into the grove of cedars that ring the 'green'. One of the few 'deuce or die' holes on the course. Get yours.
The legendary hole 6 at Idlewild is the definition of a placement hole. The ideal tee shot doesn't have to be long, but under control to get to the landing zone in such a way as to give you a line into the S bend approach. A Fariway driver or even a mid off the tee that gently fades right to left is the usual choice. Then, if you've got a controlled forehand (rhfh), you have a chance to get to the 'green' in 2 (or 3). Four is a good score on this hole for most players.
Choose a disc that works left to right for you, under control to hit the lane up to the right to the short pin. There are gaps here and there on the right of the fairway, but they're low percentage. Most players going for the long basket want to get to the landing zone left of the short for a clean, pond-crossing upshot.
Smooth is far. Most players can't reach this for the deuce, so you're looking to get way down the fairway off the tee to place the approach shot anywhere close that's not blocked by that cedar. Overthrows can go far as the ground falls away past the basket.
Play it safe and just try to place your drive somewhere near the bottom of the hill that heads up to the short basket. From here you'll have a decent look at either pin.
If you don't have a crazy, big arm sky hyzer (rhbh) that can get you over the trees and up on the ridge (most of us don't), I've seen the very smart players go conservative to the landing zone at the bottom. A smart drive here breaks this killer hole into bite-sized pieces: LZ, top of ridge, approach, then a safe 4 (not MY usual 6).
