Easy Steps to Long, Straight Shots
By Kim Jeong-kyooKorea Times Golf Columnist

To hit the long, straight drives, accurate irons and precise partial shots, it's essential to be committed to sound pre-swing basics, hard practice and dedication to the game. However, they are not all that are required to be an advanced golfer. There are a few critical in-swing keys that all great players focus on.
Try them out one by one, pick the best two or three and incorporate them into your swing. You will hit the ball better on a more consistent basis.
1. Cross the right forearm over the left through the ball.
Many tour pros cross their right forearm over the left through impact so that their left hand is below the right just after impact. They create an X-shape in their forearms during the follow-through.
Releasing the club in that fashion increases the clubhead speed through the ball, creating more distance. That also promotes solid impact as it keeps your head from moving ahead of the ball on the downswing, which avoids a faulty outside-to-in swing path. Similarly, the motion keeps your left arm from bending at impact and during the follow-through, preventing the chicken wing.
Importantly, it guarantees to stop a slice as it delivers the clubhead to the ball with its face square or slightly closed.
A similar key to preventing slice is to rotate the back of your left hand aggressively through the ball so that it points at the ground immediately after impact. Rolling your left hand in that manner leads your right arm to rotate over your left through impact, thus squaring the clubface at impact. You will produce a straight or a powerful draw.
2. Rotate hips through the ball
All great players rotate their hips toward the target through impact. That helps hit the ball farther, straighter and more accurately.
Properly controlling the speed of your hip rotation encourages your arms to stay in front of your body at impact.
Ideally, your hips need to be open about 45 degrees at impact but your goal needs to be rotating your hips completely through to the finish so that your belt buckle is pointing at the target at the completion of your swing.
Rotating your hips properly with your head still will prompt you to finish your swing with your back arched in a position resembling a reverse C-shape, but golfers with back pain need to avoid the reverse C-shaped finish as it puts unnecessary strain on the lower back.
A good way to avoid this C-shaped finish or rather to control the speed of your hip rotation is to focus on placing your right shoulder over your left foot in the follow-through with the majority of your bodyweight on the back of your left heel. That promotes proper hip rotation and powerful clubhead release, improving balance.
3. Maintain the side tilt of your spine to the right away from the target
For a proper setup it's essential to tilt your spine right away from the target and to hit the ball firmly you need to maintain the side tilt of the spine throughout the swing. That facilitates delivering the club to the ball on a path that is from inside the ball-target line, enabling you to keep your arms in front of the body at impact without a conscious effort.
Keeping the spine angle intact also helps keep your arms and body moving in synchronization during the downswing.
A good way to maintain the spine angle throughout the swing is protruding your rear end out backward at address and maintain the position during the entire swing. Sticking your rear out will cause your buttocks to position behind your heel line, causing a tight tension felt on the small of your back.
Importantly, that gets the roundness out of your spine, guaranteeing the natural curve on your lower back. A straight spine is essential to turn your body freely on the backswing and swing the club down on the proper inside path, two ingredients for solid powerful impact.
4. Maintain angle on the right wrist
Crucial to hitting the ball far and straight is to maintain the angle formed on the right wrist during the backswing late into the downswing.
Advanced golfers make sure that the clubhead stays still above their head when their hands are at waist level. That happens as they maintain the wrist hinge late into the downswing. Delaying your release leads to storing power until the last moment, thus maximizing the clubhead speed at impact.
Importantly, delaying the release prevents the coming-over-the-top problem, enabling you to hit the ball powerfully on a path that is from inside the ball-target line.

The right arm after follow through

Indeed straight...

Baseball swing

Try wood swing to iron. It works mysteriously.
Not sure though if the same I can do with real ball at the range or field.
Another issue would be slices, which I see in the wood swing.

Automatic weight shift

1. Start addressing the ball on the left foot side

2. Weight is more than 70% on the left foot, default position.

3. During backswing, weight shifts to the rigth foot momentarily, then comes back to the left foot, the default position, "automatically".

4. There is "a bit of" body translation back during backswing to forward during downswing, helping weight shift described in 3.

5. Stance should a bit WIDE with asymmetricity due to the left leaned ball position to ease the body translation and straight impact.

c.f. During impact, weight should be on the left foot. Above tip ensures this occurs automatically.

Irons sucked
Woods so so

You are looking at your ball almost vertically.
Especially for higher number irons.

Spine almost upright
Neck and head bent forward

Spine+neck lean forward together

Oscillation, ball position, and knees

1.
When addressing, you often do "stepping" between your right and left foot.
This is very good for feeling the shift of center of mass between feet.
The way you step is like "damped 1st harmonic oscillation".
At first large steps and gradually smaller steps and at the end of it, start of swing.

2.
Be aware that the optimal ball position changes depending on the situation:
i.e. the first iron swing and the same iron swing after using woods will have
different optimal ball position.
For me, it goes more than the middle to "close and square" the face the club head.
Thus optimal ball position tends to go further left side.


3.
For irons, left knee can bend quite a lot. It's natural motion induced by other body
motion. Thus, don't try to force a certain knee posture and accomodate other
body motion. Never.

Another improvement

DON'T NEED TO BEND YOUR KNEES TOO CONCIOUSLY.

AIM THE BACK BOTTOM OF THE BALL.

Another KEYS

1. "Fasten" your right foot and knee: you remember the twisting motion?!

2. Chin up and should be able to see your left shoulder passes and comes back.
