Ok, so I read "The Natural Swing" by George Knudson by DaGolfDocs request, but his grip is confusing me, it seems to me he suggests both thumb to go down the middle of the shaft.

Do one of you have a picture or video of proper grip?

i do ill trade it for your avatar pic

Google it ffs

Here is some info my coach gave me on the grip...the biggest improvment to my game is because of this.

The Grip
The grip is the MOST important part in golf. Your grip controls the power and the spin of the ball which controls
which direction the ball will move. 75% of all golfers play right handed in Canada and that number increases to 90% in
the USA…the reason for the difference - hockey. So to help both left and right handed golfers with the explanation we
use the terms target and trail. Your target side is the side closest to the target and your trail side is the side following.
Target -The Top Hand
The grip hits two points of your hand; the middle knuckle of your index finger and the lower palm. The shaft sits
diagonally across the fingers. Close your fingers and wrap that hand around the grip. The top target thumb will be
placed on the opposite side of the shaft. For example, the target thumb will sit on the trail side of the middle of the
shaft.
The grip pressure of the top hand is like a firm mans’ hand shake. This hand is a firmer grip than the bottom hand. The
hand should be relaxed enough to squish onto the grip. If there is a gap, the grip pressure is too tense or stressed.
There is a “V” formed between the top thumb and the index finger. This “V” will point to the trail shoulder. That is the
target hand V points to the trail shoulder.
Trail -The Bottom Hand
There are three types of grips: the baseball grip where the player has 10 fingers on the grip; the interlocking grip where
8 fingers are on the grip and the overlapping or over-locking grip, where 9 fingers are on the grip. 90% of golfers
worldwide use the latter grip. This is the grip we prefer and the grip we encourage our students to adopt.
Spread out the bottom hand so all fingers are not touching each other and place the pinkie finger in between the index
and middle finger of the top hand. The index finger of the top hand should be raised so the pinkie doesn’t slide around.
All three fingers of the bottom hand can now be wrapped around the grip. It is common to see the ring finger squishing
the index finger of the opposite hand. Do not let this happen as a blister will probably occur.
Wrap the bottom hand around so the top thumb is hidden. The bottom index finger should be BESIDE the grip to
impart power…not under the grip. The bottom thumb is placed on the other side of the middle of the grip. There is
another “V”, formed between the bottom thumb and the index finger. This “V” should point to your chin or slightly to
the trail side. Not too tight with this hand! The feeling should be of a person shaking an elderly hand.

I may or may not be accurate here, but I understood OP's question to be how George Knudson grips the club according to his book "The Natural Golfer". Not what a standard grip looks and feels like.

BO

Fixing my right thumb on the grip took 5 strokes off my scores instantly. I read Hogan's book and iirc it suggests thumb rests on left side of shaft. Well that felt funny to me so I kept it on the right side of the shaft (while squeezing between my thumb and index finger). That "felt" like a compromise between what he suggested and me having pretty small hands.

Anyway yeah I separated my thumb from my palm and it's on the left side of the shaft and it makes a loose "hook" with the tip of my index finger. Now the clubhead always feels like it just follows my left (lead) arm and my right hand is just along for the ride. My ball striking got much better and more consistent. 5 strokes to move a thumb one damn inch. It felt flimsy at first but the results kept being good so I just went with it.

I'm sure some "pro" will rush in and tell me how this is still wrong but I was amazed at how much difference something so minor could make.

Compared to this:



^^ Is the thing that looks most like the grip in the book, I could find on google.

So which one is correct, and has anyone read and understood the book who can tell me how to do it right?

EDIT: What we are looking at is the right thumb
