Niall,
My original post may have been worded clumsily. The photo at Chambers is before they narrowed the fairway. I believe they've brought the fairway in 20 yards or so on the right (locals, please correct me if I'm wrong). Even with the narrowed fairway, it is still uber-wide. However, the strategic line to the right hand pin is adversely impacted. With the lion's mouth bunker, it really pays to be on the correct side of the fairway to have a chance to get close.
