Pull Hooks
 

Last round I hit numerous pull hooks with all irons, but most noticeably with the shorter irons. But I was cranking the driver straight and long.

I have been focusing on keeping the head still and rolling down the line.

Might this be a flat left wrist issue?

You can pull it with the face . . . Like if you roll the face off the plane early and then roll . . . your path may be good but the face came off the plane . . . Or you could just slap come over it.

What's the Problem?
 

As advocated by Harvey Penick some time back.
"First decide if the thing to work on is the swing itself or the angle of the clubface at impact"

Timeless good advice eh?
