Impact.

The strike. Compare it to Address. Stock full-swing mid-iron.

Driver is a sweep, not a chop.

What's going on.

This is the ball. Face-on shows hands a bit ahead, and whether you are on the front foot. Down-the-line is whether the address space is still there.

What this still is.

This is the strike. Compare it to Address.

Look first.

Face-on

Hands a bit ahead of the clubhead on a mid-iron. You are on your front foot, not still on the back one.

Check these.

Hands relative to body
Hands are ahead of the clubhead on a mid-iron. The handle still leads.

A little ahead is still this still. A press is not required.

Wrist picture
The handle still leads. The clubhead catching the hands is allowed here.

Passing them is the next still, after the ball. You are reading the club, not a hinge.

Shaft to wrists / lead arm
Forward lean on a mid-iron.

A little is still this still. Already vertical is no shaft lean. A flip is scoop.

Hip rotation / belt / depth
The belt is open to the flag.

How open is a style, not a test. Still on the back foot at the hit is hanging back. Space toward the ball is the other camera.

Shoulder rotation
Shoulders are opening. The chest is starting to face the ball.

Address was square. This is not address.

Hip-to-shoulder difference
The belt is often more open than the shoulders. Address is not the hit.
Foot pressure
The front foot owns the ground. The trail heel can be up.

Still on the back foot at the hit is hanging back.

Down-the-line

The space from address is still there. You have not stood closer to the ball.

Check these.

Hands relative to body
Hands stay on the original line. Not thrown out, and not buried.
Wrist picture
The toe can hint.

You cannot see whether the face looks at the flag from this camera.

Shaft to wrists / lead arm
The shaft still matches the address plane, or sits a little under.

A steep wipe, or a hook around the body, is the miss.

Hip rotation / belt / depth
Compare belt space to address. If the hips are closer to the ball, that is early extension.
Shoulder rotation
The tilt from the hips is still there.

Getting much taller is loss of posture. Space toward the ball is the hip row.

Hip-to-shoulder difference
Hips are open. Shoulders are catching up.
Foot pressure
You see the trail foot coming off more than you see a load split.

You cannot see which foot owns the ground from this camera.

When both cameras agree, the hands still lead a mid-iron and the address space is still there.

How you see it here.

  • Down-the-line, belt closer than Address is early extension. Early extension
  • Face-on, if you are still on your back foot at the hit, that is hanging back. Hanging back
  • A mid-iron shaft that is already vertical is no shaft lean. No shaft lean
  • The clubhead already past the hands at the ball is a scoop. Scoop
  • Standing up into the strike is loss of posture. Loss of posture

Official YouTube. Start times are the bit that teaches this slide, not the whole swing.

He names the Impact check: pelvis closer to the ball than it was at Address. Watch that down-the-line pair.

Watch the face-on stand-up into the strike. That is loss of posture, not early extension. After the ball is a different picture.

They name the miss: treating Impact as Address. Watch how open the belt is at the strike versus the start. How open is a band, not a freeze.
