Seems to be a dogleg left bias. It is almost as if the guy who did the routing liked to hit a power fade. 
It's less-slanted to Nicklaus' left-to-right ball flight than many other designs of his that I have played.
To wit:
1: No real movement needed on the drive. Second shot favors R-to-L
2: Favors a R-to-L drive and a L-to-R second shot. Good hole.
3: L-to-R is really the only way to come in at the green.
4: Tons of options off the tee, a huge bomber would favor R-to-L. Second shot is just a wedge, not much movement necessary.
5: R-to-L tee shot.
6: L-to-R approach to par 3 green.
7: L-to-R tee shot, second depends on where the hole is located.
8: Some slight advantage to a L-to-R tee shot, maybe.
9: L-to-R off the tee, R-to-L approach.
10: R-to-L tee shot is favored.
11: Not sure the tee shot favors one or the other. If going for it in two, R-to-L is preferred.
12: Depends on pin placement.
13: L-to-R tee shot and second shot preferred.
14: R-to-L approach preferred.
15: Not much advantage to one or the other.
16: R-to-L par 3.
17: L-to-R tee shot, L-to-R approach, usually.
18: Not much advantage off tee, maybe a slight L-to-R bias. R-to-L approach.
So, for drives you have 4 holes that favor a right-to-left shot and 4 that favor a left-to-right shot, to varying degrees.
For approaches, 6 favor a right-to-left, 5 favor left-to-right.
Pretty even.
