Symptom
I putt well in practice and badly on the course
Putts that drop on the practice green start missing once you are on the course, and the misses get worse when the putt actually matters.
This usually traces to something already true before the club moves: grip, aim, posture, or where the ball sits in your stance. All of those are checkable standing still, which is why the questions ask you to look rather than to guess.

Narrow it to one cause
Each question is here because golfers answer it differently, and that difference is what rules a cause out. Nothing is generated while you answer: every question, cause and fix was written and checked in advance.
A few questions · no account needed
What you will be asked
- When a putt that matters goes wrong on the course, what does the ball usually do?
- Compare a putt that matters with one on the practice green. What changes before the putter moves?
- Squeeze the putter grip as hard as you can and call that ten. What number are you holding it at over a putt that matters?
- Hold your finish on a putt that matters. How does the stroke compare with your practice stroke?
- When is your putting furthest from how you putt in practice?
- As the putter starts back on a putt that matters, how settled is your plan?
Where this can come from
These are the causes this symptom resolves to, in the order they turn up most often. That order is not a diagnosis and it is not your answer: two of them can produce a shot that looks identical from behind. Each has a fix you can read now, whether or not you answer anything.
No repeatable setup or routine
Aim, ball position, stance width and grip get rebuilt slightly differently on every shot, so face angle, low point and strike location all vary with them. Address is the reference the whole swing is measured from, and a reference that moves explains misses that seem to have no pattern.

Grip pressure too tight
Holding the club hard enough to tense the hands and forearms makes the delivered face angle less repeatable and shortens the motion. It is the most common physical expression of pressure, which is why the same golfer strikes it well on the range and loses the face on the first tee.
Read the fix
Deceleration into impact
The club slows down before it reaches the ball, almost always after a backswing longer than the shot required. Speed disappears at the only moment it matters, and the bottom of the arc becomes unpredictable, which is why decelerating produces both the chunk and the blade.
Read the fix
Putter face open or closed at impact
Start direction on a putt is set almost entirely by where the face points when it meets the ball. The shorter the putt, the less room there is for anything to hide a small face error, which is why short putts miss for reasons that feel invisible.
Read the fix
Break not matched to the pace
Slope acts on a ball for as long as it keeps rolling, so the same putt takes more break when it is rolled softly and less when it is firm. Reading a line without deciding a pace, or hitting a different pace than the read assumed, misses on either side.

These are not here because they sound similar. Each one can come from a cause on the list above, which is why fixing one sometimes quietly fixes another. The closest matches are first.
