Grip:
Written with a right-handed golfer in mind.
A proper grip will reduce your tendency to slice your golf ball. A good grip helps keep the club head square at impact.
Your grip should have a relaxed and comfortable feel. A tight grip will hinder your rhythm and release.
The biggest problem I see is people getting the club in the palm of their hands and not their fingers. Thinking of the top of your club as a clock with 12:00 being a square club face to the target, get your heel pad of your left hand to wrap over to about 1:00. Wrapping your 4 fingers underneath the club, with your thumb down the right-center of the shaft. If done correctly you will make the letter “V” between your thumb and forefinger (pointer). That letter “V” should point to your right shoulder.
With your right hand you have a life line going down the middle of your palm, you should use that part of your hand to cover the left thumb. If done correctly you should make another letter “V” between your thumb and forefinger. That “V” should also point to your right shoulder. Now your hands will work together instead of against each other.
Connecting your hands together is also important. The 3 ways to do this is:
Interlock - Putting your right pinky finger between your left forefinger and middle finger.
Over-lap - Putting your right pinky finger on top between your forefinger and middle finger.
Ten Finger (baseball) - Putting all fingers on club together. This is not a grip I recommend except to persons with small hands or juniors. If you do choose to use this grip be sure that both your hands stay together and not separate them.
If the first time you try this grip and it feels uncomfortable its probably correct. After a little while it will feel normal and you will be on your way to solider, straighter golf shots!
