Hole-by-hole guide to Oakmont Country Club, Pittsburgh:

1st, 482 yards, par 4: A really demanding opener, with the second shot blind to a green that slopes from front to back.

2nd, 440 yards, par 4: Irons for many off the tee with a ditch left and bunkers right, but downwind some will try to get as close as they can to a green where three putts are common.

3rd, 428 yards, par 4: Famous Church Pew bunkers are left of the fairway and the bunkers on the right are no fun either. Elevated green is relatively flat.

4th, 609 yards, par 5: Long enough, but nearly 60 yards shorter than the record-breaking 12th. Not necessarily a driver off the tee because accuracy is so important.

5th, 382 yards, par 4: Irons for position the usual course of action, leaving an approach to one of the most undulating greens.

6th, 194 yards, par 3: First of the short holes has a small green which slopes from right to left.

7th, 479 yards, par 4: Another hole where par is a real achievement. Left of the green is the main danger, while the putting surface itself is angled severely from left to right.

8th, 288 yards, par 3: Longest par three in major history. Green might well be out of reach for some, while anything slightly left likely to find Sahara bunker that is 100 yards long.

9th, 477 yards, par 4: Plays as a par five for club members. Blind uphill drive with ditch left and pot bunkers right. Another demanding green.

10th, 462 yards, par 4: Downhill, but narrow drive where it is imperative to avoid the bunkers down the right.

11th, 379 yards, par 4: Iron or three-wood to reach a plateau on the fairway, leaving an approach to a green which slopes from back to front.

12th, 667 yards, par 5: Longest par five ever in majors and strategy will play a big part. Like the fourth some may keep driver in the bag, even though it will mean a far longer third shot.

13th, 183 yards, par 3: Hour-glass green is very narrow and crucial thing is to leave an uphill putt.

14th, 358 yards, par 4: Driveable in favourable conditions. Making birdie or even eagle, though, depends on coping with a large green that has a lot of subtlety to it.

15th, 499 yards, par 4: Blind tee shot to a fairway that slopes left to right. More church pew bunkers down the left, with ditches and further bunkers on the right.

16th, 231 yards, par 3: The large green slopes left to right and while much shorter than the eighth many are predicting this will be the tougher of the two.

17th, 313 yards, par 4: Opportunity to make up lost ground, but there are risks attached. Bunkers lie in wait 50 yards short of the green on the left-hand side.

18th, 484 yards, par 4: One of the toughest closing par fours in golf. Long and straight needed for both the drive and the second shot to an undulating green.
