One of the trickiest drives on the course.

The tee shot has to be played all the way down the right, but unfortunately the out of bounds follows the same path.

There will be a number of competitors looking to reach the green in two. To make life difficult for them, a water hazard called the Suez Canal lies in wait at about 320 yards for the big drivers.

Some players will be looking to lay up, but for those safety-conscious golfers, there are two pot bunkers in the middle of the fairway.

Those playing a long iron to the green from near the water hazard will find out of bounds is right next to the putting surface.

I think this hole will be an important factor in deciding the outcome of the Open - especially come Saturday and Sunday.
