For years, I have had trouble with my clubface staying square in my backswing. It likes to close, and though I made great contact, the ball would careen to the left.
After trying everything I could think of to make it a habit to keep the clubface square, I thought, maybe it’s in my grip. Not whether I have a strong, neutral, or weak grip. but which kind of grip I use.
Everyone uses an overlapping grip by default. Something different would be a ten-finger grip.
It didn’t take much time to find out that I had much more control of the clubface with this grip, and it was easier to feel when the clubface was square as I took the club back, or whether it had closed.
And easier to keep the clubface square.
I’m hitting the ball much straighter now, and making more authoritative strikes.
There’s a piece in Harvey Penick’s blue book (p. 148) about Jimmy Demaret saying,
“In a reasonable swing, the right hand won’t take over from the left in a full-fingered grip. The two hands will work together. You get more power and better control.”
To which I say, yes, yes, and yes.
Give it a try. It’s not hard to get used to and you might be pleased with what you get.
