TEPaul & Chipoat,
The concept of hitting to the left of the row of left side fairway bunkers is misquided because the aerial doesn't reveal the right to left nature of the terrain.
The area between the bunkers and the left rough is extremely narrow. It is further narrowed by the slope of the terrain, right to left. It would be a foolish target for any level of golfer. It is doubtful that a straight drive, or a drive with draw or hook could come to rest there, understanding the nature of the trajectory required to clear the bunkers.
A cut or fade would have a better chance, but who would aim into the rough, to a super narrow corridor of fairway bordered by menacing bunkers
I think the play is in conformity with risk/reward found throughout the golf course.
The ideal drive is a drive right of the bunkers, allowing either the terrain or the flight of the ball to bring the ball close to the bunkers, setting up the shortest, but most aerial approach to a green angled right to left.
Emmett also allowed for the ground game for those choosing a longer or safer route to the right.
The green sits below the level of the fairway in the drive zone, this falloff, coupled with the right to left nature of the approach area allows a ball with less carry to navigate its way to the green via the terrain and/or reduced ball flight/height.
However, with the pin along the right perimeter of the green, approaches from the latter angle would have a difficult time getting close to the hole, and shots that bounced straight, or were hit a little right of the target line would find deep, difficult bunkers to the right of the green and face a very difficult down hill recovery shot.
I don't believe that going left of the left side bunker line was ever intended as a prudent line of play. So I believe we can dispense with that theory, the terrain and relative position and dimensions of the bunkers, left side fairway and rough won't support it.
The concept of deepening every bunker to counter the Sand Wedge and L-Wedge doesn't justify the expense.
