The tee shot is not dissimilar to the drive off the 13th - there are bunkers to the left and right.

To take them all out of play, you have to carry it the best part of 290 yards - even the longest hitters would need a bit of breeze.

The further you hit the tee shot, the more the fairway bottlenecks in.

If you lay up short to bunkers, in particular to the one on the right, then you're faced with a long second.

There are three bunkers guarding the front of the green, but nothing to its left or right.

However, there are plenty of bumps and hollows around the putting surface.

There's a very narrow target for the golfers to aim at, and coupled with the long-iron approach, it makes the 15th one of the most fascinating par fours in golf.
