Your grip changes more than your hands
A grip adjustment can change how you deliver the clubface without a deliberate swing change. But a stronger grip is not a universal slice cure: the ball’s curve depends on the face relative to its path at impact.
How one adjustment can trade one miss for another
Original GolfSpark instructional illustration
For a right-handed golfer, rotating both hands slightly clockwise around the handle creates a stronger grip. More left-hand knuckles are usually visible. That arrangement can help some players return the face less open. Rotating the hands the other way produces a weaker grip.
The complication is that the face does not act alone. Strengthen the grip while retaining the same swing path and the result may become a pull or hook rather than the intended straight shot. A useful correction depends on the pattern you actually deliver.
With the face square at address, try small changes in both directions and notice how the wrists feel. Then observe the start direction and curve of real shots. That makes the grip an experiment with evidence, rather than a permanent change based on the hope that one position suits everybody.
