Hole-by-hole guide to Southern Hills:

1st, 464 yards, par 4: Drive is from elevated tee to a dogleg left with bunkers on the outside of the angle. Green slopes from front to back and is guarded by three traps.

2nd, 488 yards, par 4: Drive requires a 260-yard carry over cross bunkers and a meandering creek. Green is well-bunkered.

3rd, 451 yards, par 4: Dogleg left where the right centre of the fairway opens up the hole.

4th, 372 Yards, par 4: Rolling fairway leads to a heavily-bunkered elevated green, sloping back to front.

5th, 653 yards, par 5: Slight dogleg left. Narrow landing area between bunkers causes problems and plenty of trees and heavy rough lie in wait for any straying off line as well.

6th, 200 yards, par 3: First of the short holes has creek down the left and out of bounds is close behind the green. Green tilts back to front and is heavily bunkered in front.

7th, 384 yards, par 4: Blind tee shot to the brow of a hill. Narrow green is bunkered front and left. 8th, 245 yards, par 3: Tough hole placements possible here. Better to be short than over the embankment at the back. Very few birdies made here.

9th, 374 yards, par 4: Dogleg right with bunker guarding the corner. Prevailing wind and elevated green make the hole play longer than its yardage and green slopes severely from the back.

10th, 366 yards, par 4: Trouble on the right of this dogleg right. The short approach shot to this elevated two-level green must be kept below the hole to have a reasonable birdie chance.

11th, 173 yards, par 3: Shortest hole on the course. Small green is surrounded by four bunkers and the prevailing right-to-left wind adds to the degree of difficulty.

12th, 458 yards, par 4: Slight dogleg left calls for accurate drive to a blind landing area sloping right to left. Approach has to carry water and bunkers to the well-banked green.

13th, 537 yards, par 5: Slight dogleg left is reachable in two for the big hitters. Small green is well-protected by sand and water.

14th, 223 yards, par 3: Six bunkers and out-of-bounds on the left will test the entire field, especially if the prevailing right to left wind is blowing.

15th, 413 yards, par 4: Dogleg left with bunker guarding the corner. Second shot must then avoid bunkers and the green is sure to see a number of three-putts.

16th, 507 yards, par 5: Longest par four on the course. Aim of the drive is to carry a slope 245 yards off the tee. Shorter shots leave a blind second.

17th, 358 yards, par 4: Shortest par four doglegs right and anything going right towards the trees and a creek will present a real problem. Shallow, two-level elevated green.

18th, 465 yards, par 4: Dogleg right requires a drive to a plateau on the left side of the fairway 200 yards from the elevated green. Severely sloping green from back to front will cause many three-putts as seen at the climax of the 2001 US Open won by Retief Goosen.
