saltiresfan: Back pin at STA17
Im yet to master the shot, but one way of approaching is to go right of the bunker with some top-spin, as the green naturally progresses around the corner and then down toward the hole. I've birdied it a few times using this method and if my approach is off its still a fairly comfortable par..
hope this is helpful, (I spent ages trying to approach it using backspin, but from the black tee's its not really an option anymore)
