I did learn something in this.
In pro play, say a green is cut super slick, such that the ball rarely if ever, rests on the green, but rolls off of it. The type of green where most players take 3-5 strokes,..or more,..on the approach to get in the cup.
If there is a water hazard, the smart play is to approach closest the cup with no spin, then allow the gradient on the green to take the ball off the green into the water hazard, setting a new line for the next stroke.
Then you have a new line directly along the green’s gradient to the cup. Making a much more reliable approach than any other, but not living up to the intent of it being a penalty shot with more risk than the original.
Depends,lateral hazard?
