Is this pic showing left hand neutral or strong grip?

It's hard to tell from that photo. In "my world" a neutral grip is when you can have a flat left wrist and the face is parallel to your left arm at the top of your swing.

I've seen this somewhere. Whatever your hands look like while they are naturally hanging is YOUR neutral. Some people see two knuckles, some see three and some see one. It just depends on your body what your neutral is.
