fatshot I'm in 'Chipping Hell' right now.
I was there early this season and shanking many of them. Several times I shanked the same chip several times. What I finally started doing is taking the lowest loft club that would get me on to the green surface, keep my wrists locked with ball in the center of of my stance and put a shoulder rocking putting stroke on it. Since than no shanks and most have been getting close to the hole. Sounds weird but it is working for me. Usually a 6 or 7 irons is used.
