If you're looking for more yards and thinking of strengthening your grip -- turning one or both hands to the left to facilitate the release of the clubhead -- you're on the right track. Beware, however, that an overly strong left hand actually can do more damage than good, resulting in a fade or slice. If you're going to strengthen your grip, focus on the right hand, not the left. Here's why:
Turning the left hand under on the golf club (so the V formed by the thumb and forefinger points outside the left shoulder) forces the left wrist to bow. This is a restrictive position. Instead of encouraging a faster release, the left hand is less mobile and occasionally will turn even more under through impact, further opening the clubface.
This arched position promotes a faster forearm rotation through impact, making it easier to square or even slightly close the clubface.
If you do decide to experiment with a stronger grip, turn the right hand so you can see three or more knuckles and keep the left hand neutral, the palm facing the target. That's the best position for the quick release necessary to draw the ball.
