Jacksonville, Florida. 2019 WPBA Tour event.
Quarterfinal match. Hill-hill. I’m shooting.
Straight-in 8-ball. Six inches from pocket. Looks simple.
The position requirement: If I make it, I win. If I miss, cue ball must stay near object ball (safe position).
Correct shot: Stop shot. Cue ball stops dead on contact. Miss leaves no runout for opponent.
What I executed: Follow shot. Hit slightly above center.
Result:
Made the 8-ball. But cue ball rolled three feet forward past pocket.
Opponent had straight shot on her ball. Ran out. Won match.
Prize difference: $3,200 (2nd place vs. 1st place).
The mistake: Aiming for stop shot but striking 2mm too high on cue ball. Just 2mm error converted stop shot into follow shot.
Here’s every technical detail separating stop shots from follow shots that determines match outcomes.
Quick Takeaways: Stop Shot vs. Follow Shot
- Stop shot: Strike cue ball at center (no spin), ball stops dead on object ball contact
- Follow shot: Strike cue ball above center (topspin), ball continues rolling forward after contact
- Optimal stop shot contact point: 0-2mm below true center (compensates for cue elevation)
- Follow shot contact point: 5-10mm above center (moderate follow), 10-15mm (aggressive follow)
- Speed requirement: Stop shots require medium-firm speed, too soft won’t stop, too hard causes hop
Stop Shot Fundamentals
Definition: Cue ball stops immediately upon contact with object ball.
Physics:
When you strike cue ball at center with no topspin or backspin, ball travels with pure sliding motion (no rotation). Upon contact with object ball, friction with table surface stops sliding ball immediately.
Perfect Stop Shot Mechanics
Cue Ball Contact Point:
True center is geometric center of ball. But cues aren’t perfectly level—typical elevation angle is 3-7 degrees.
Effective center (accounting for cue elevation):
- For 5-degree cue elevation: Strike 1-2mm below geometric center
- For 3-degree elevation: Strike 0-1mm below center
- For 7-degree elevation: Strike 2-3mm below center
Why strike below center?
Cue elevation causes “effective contact point” to shift upward. Striking slightly below geometric center compensates for this, delivering pure center-ball hit.
My Calibration Method:
Set up straight-in shot, 3 feet distance. Strike at various points near center. Observe cue ball behavior after contact.
Perfect stop: Cue ball stops within 1-2 inches of contact point.
Slight follow: Cue ball rolls 3-6 inches forward (struck too high).
Slight draw: Cue ball backs up 3-6 inches (struck too low).
Adjust until you find your zero-spin contact point. This is your personal “center ball” for stop shots.
Speed Requirements for Stop Shots
Critical Finding:
Stop shots require medium to medium-firm speed. Too soft or too hard fails to stop.
Why:
Too soft: Ball begins rotating (picking up topspin) before reaching object ball. Rotating ball continues rolling after contact.
Too hard: Ball hops slightly upon contact due to compression force. Hopping ball has forward momentum that continues after landing.
Optimal speed range: Ball travels with pure slide for entire distance to object ball, contacts object ball while still sliding (no rotation), friction stops it immediately.
Distance-Speed Relationship:
| Distance to Object Ball | Required Speed (1-10 scale) | Impact Force |
|————————|—————————-|————–|
| 1-2 feet | 4-5 (soft-medium) | Gentle |
| 2-4 feet | 5-6 (medium) | Moderate |
| 4-6 feet | 6-7 (medium-firm) | Firm |
| 6+ feet | 7-8 (firm) | Strong |
Why speed increases with distance:
Longer distance = more time for ball to pick up rotation from table friction. Higher speed maintains slide motion for longer distance.
Common Stop Shot Errors
Error 1: Striking Too High (Accidental Follow)
My Jacksonville mistake. Aimed for center, hit 2mm high.
Result: Slight topspin causes cue ball to roll forward 1-3 feet.
Solution: Lower contact point 1-2mm. Practice with chalk mark on cue ball at your zero-spin point.
Error 2: Too Soft Speed
Symptom: Cue ball rolls forward 6-12 inches after contact.
Cause: Ball picks up forward rotation during travel, arrives at object ball with topspin.
Solution: Increase stroke speed one level (soft-medium → medium, medium → medium-firm).
Error 3: Too Hard Speed
Symptom: Cue ball hops on contact, rolls forward 3-6 inches after landing.
Cause: Excessive impact force compresses balls, causes cue ball to hop, forward momentum continues after landing.
Solution: Reduce stroke speed one level. Stop shots rarely require power—control is priority.
Error 4: Incorrect Cue Elevation
Symptom: Can’t find consistent zero-spin contact point.
Cause: Cue elevation varies shot to shot. Higher elevation shifts effective contact point upward.
Solution: Maintain consistent cue elevation (3-5 degrees typical). Use same bridge height for all stop shots.
Follow Shot Fundamentals
Definition: Cue ball continues rolling forward after contact with object ball.
Physics:
Striking above center imparts topspin (forward rotation). After contact with object ball, topspin causes cue ball to continue rolling in direction of rotation.
Follow Shot Mechanics
Cue Ball Contact Point:
Amount of follow depends on contact point height:
- Soft follow (1-2 feet forward): 5-7mm above center
- Medium follow (2-4 feet forward): 7-10mm above center
- Aggressive follow (4+ feet forward): 10-15mm above center
- Maximum follow: 15-18mm above center (near miscue limit)
Miscue Limit:
Chalk contact area extends approximately 18-20mm from center. Beyond this, cue slips off ball (miscue).
My Maximum Follow Contact Point: 16mm above center (80% of maximum possible)
Why not use full 20mm?
Risk of miscue increases dramatically above 16-17mm. Risk/reward favors slightly lower contact point with reliable execution.
Speed Requirements for Follow Shots
Unlike stop shots, follow shots work across wide speed range.
Soft Follow:
- Speed: 3-4 (soft)
- Follow distance: 1-2 feet
- Use case: Delicate position play, avoid over-running position
Medium Follow:
- Speed: 5-6 (medium)
- Follow distance: 2-4 feet
- Use case: Standard position play, most common follow shot
Aggressive Follow:
- Speed: 7-9 (firm to hard)
- Follow distance: 4-8+ feet
- Use case: Getting from one end of table to other, breaking up clusters
Speed-Distance Relationship:
Unlike stop shots (where excess speed causes problems), follow shots benefit from speed. More speed = more follow distance (up to practical limits).
Common Follow Shot Errors
Error 1: Insufficient Topspin
Symptom: Expected 3 feet of follow, got 6 inches.
Cause: Struck too close to center (minimal topspin).
Solution: Raise contact point 3-5mm. Practice recognizing difference between 5mm, 10mm, 15mm above center.
Error 2: Excessive Topspin (Miscue Risk)
Symptom: Cue slips off ball occasionally, or heavy english applied unintentionally.
Cause: Striking too high (beyond reliable contact zone).
Solution: Lower contact point to 12-15mm above center. Prioritize consistency over maximum follow.
Error 3: Insufficient Speed
Symptom: Topspin applied correctly, but ball doesn’t follow expected distance.
Cause: Too soft stroke. Topspin dissipates due to table friction before ball travels full distance.
Solution: Increase stroke speed. Aggressive follow shots require firm to hard speed.
Error 4: Path Miscalculation
Symptom: Cue ball follows but not in expected direction.
Cause: Follow path depends on cut angle. Thin cuts cause cue ball to curve, thick cuts maintain straighter path.
Solution: Learn tangent line deflection angles (covered in advanced position play).
Stop Shot vs. Follow Shot: Decision Framework
When to Use Stop Shot:
- Safety Position: If you miss, leaving cue ball near object ball prevents opponent runout
- Precise Positioning: Need cue ball to stop at specific location (near object ball)
- Avoiding Scratches: Preventing cue ball from rolling into pocket after contact
- Defensive Play: Eliminating opponent’s position options by keeping balls clustered
When to Use Follow Shot:
- Forward Position: Need cue ball to travel toward next shot location
- Breaking Clusters: Following through object ball to separate nearby balls
- Table-Length Position: Getting from one end of table to other
- Avoiding Obstacles: Following path curves around interfering balls
Jacksonville Match Analysis (My $3,200 Mistake)
Situation Review:
- Hill-hill, quarterfinal match
- Straight-in 8-ball, 6 inches from pocket
- If I make it: win match, advance to semifinals
- If I miss: leave safe position (no runout for opponent)
Correct Shot Selection: Stop shot
Why?
If I miss, cue ball stopping near 8-ball leaves opponent no shot. Even if I make it, stopping cue ball prevents accidental scratch into same pocket.
What I Executed: Follow shot (2mm too high on cue ball)
Why The Error Happened:
Pressure. Match point. Prize money. Rushing pre-shot routine.
Normal pre-shot routine: 8.2 seconds (measured average)
Jacksonville shot: 4.7 seconds (43% faster than normal)
Rushed bridge setup. Didn’t verify cue tip contact point. Struck 2mm high.
Result:
Made 8-ball. Cue ball followed 38 inches past pocket. Left opponent straight-in shot on her remaining ball.
Opponent ran out. Won match.
Lesson:
Stop shots require precision. 2mm error converts stop into follow. Under pressure, slow down pre-shot routine—accuracy matters more than speed.

"acceptedAnswer": {
"@type": "Answer",
"text": "Perfect stop shot requires striking cue ball 0-2mm below geometric center to compensate for cue elevation (3-7 degree typical angle shifts effective contact point upward). Use medium to medium-firm speed based on distance: 1-2 feet requires speed 4-5, 4-6 feet requires speed 6-7. Ball must travel with pure sliding motion (no rotation) until contact. Common errors: striking too high (2mm error causes accidental follow), too soft speed (ball picks up forward rotation), too hard speed (ball hops on contact), or inconsistent cue elevation. Calibrate personal zero-spin contact point by testing straight-in shot at 3 feet until cue ball stops within 1-2 inches of contact."

"name": "What contact point creates maximum follow on the cue ball?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Maximum reliable follow contact point is 15-16mm above center (80% of theoretical maximum). Chalk contact area extends approximately 18-20mm from center, but striking beyond 16-17mm above center dramatically increases miscue risk where cue slips off ball. Follow distance depends on contact point: 5-7mm above center (soft follow 1-2 feet), 7-10mm (medium follow 2-4 feet), 10-15mm (aggressive follow 4-8+ feet). Unlike stop shots, follow shots benefit from increased speed—more speed = more follow distance. Professional player uses 16mm maximum contact point for aggressive follow rather than full 20mm to prioritize consistency over maximum distance."

Optimal speed maintains slide for entire distance: 1-2 feet requires speed 4-5, 2-4 feet requires 5-6, 4-6 feet requires 6-7, 6+ feet requires 7-8. Longer distances need higher speed to overcome table friction attempting to impart rotation. Unlike follow shots which work across wide speed range, stop shots have narrow speed window for success."
