OK, to a casual student like me, the comments about the shot patterns are profound. I am rethinking my second shots into all the greens at my course.
But, back to the 12th: When the green is very firm, that shot from the back bunker to the Sunday pin (right) has to be spot on perfect, otherwise there is a great chance of dunking it into the water with your second shot - sure death to a round. If you are facing a downhill lie in the bunker, I think you maybe have to think about intentionally leaving it in the bunker on a flat lie, to be able to spin your third. I saw Couples do this in an early round a few years ago. That scenario (along with other second shot horrors) has to be in the back of your mind during the tee shot.
