Approach shot can be on # 13 when you lay up, especially when the hole is cut close to the creek.
To the right of the green the land slopes down, toward the creek, making that pitch very, very difficult.
Back in the extended DZ, as you approach the green, the Prefered flight is a fade, so that you can use the slope of the green and stay away from the creek, but try hitting a fade off of a fairway with an 11 degree slope.
Hence a layup is often called for.
But, WHERE do you lay up to ?
