How to Check Your Snooker Stance and Sight Line with SIGHTRIGHT

What a stance and sight-line check can—and cannot—show

A stance check is useful when you want to separate the setup from the stroke. It asks a narrow question: does the line you selected behind the cue ball still look the same once your feet, shoulders and head arrive in the address position?

SIGHTRIGHT makes that comparison visible with two reference planes and a silver centre line. The trainer is made from aluminium alloy and measures 150 × 23 × 18 mm. Its curved notch sits against the cue ball, so the reference can be placed consistently beside the ball.

The tool does not decide the correct potting line, straighten the cue or promise a successful shot. It also cannot explain every miss. Cue-tip contact, delivery, speed and table conditions remain separate parts of the result. If you want the complete placement and practice sequence first, read the SIGHTRIGHT how-to guide.

Set a neutral baseline before changing your stance

Start with a straight, familiar practice line. Stand behind the cue ball and select the direction in the normal way. Only then place the trainer with the curved notch at the cue ball and the centre line pointing along the intended direction. Do not move the line simply to make the trainer look centred.

Take one clear look while standing and note the relationship between the front and rear references. This is your baseline. Walk into the shot at your usual pace, settle without cueing and look again. The purpose is comparison, so keep the ball position, target and approach the same for several repetitions.

A five-point snooker stance checklist

1. Shot lineConfirm the intended cue-ball direction while standing. The trainer checks your relationship to that chosen line; it does not choose the line for you.
2. Starting positionNotice where both feet begin before the walk-in. A different starting distance or angle can change how the rest of the body arrives.
3. Walk-inEnter at your normal speed without reaching sideways for the cue ball. Keep the same number of steps for each comparison.
4. Shoulders and headSettle naturally, then observe whether the reference appears left, centred or right. Do not twist the neck simply to force a centred picture.
5. ResetStand up completely before making an adjustment. Change one variable, repeat the same entry and compare the new view with the baseline.

How to read left, centred and right feedback

A centred view means your viewing position matches the trainer’s centre reference at that moment. A left or right view means the relationship has shifted to one side. Neither result is a medical assessment, and neither tells you that a ball will definitely be potted or missed.

The useful information is repeatability. If the view shifts to the same side on several identical walk-ins, you have a pattern worth checking. If it changes from left to right between repetitions, stabilise the approach before making a larger stance change.

Four common setup patterns to investigate

The line is centred while standing but shifts after the walk-in

Repeat the starting position and entry first. Reaching across the line, changing the lead-foot angle or lowering the head from a different side can all change the final picture. Check one part at a time instead of moving everything together.

The view changes only after you begin feathering

Return to a no-hit setup. The trainer is showing that the relationship changed after address, but it cannot tell you which part of the cue action caused it. Compare a still address with gentle feathering before adding a shot.

You can centre the view only by forcing the neck

Stand up and review the feet and body entry. A visual reference should not be used to hold an uncomfortable pose. The goal is a stable setup you can repeat without strain.

Every repetition looks different

Reduce the drill to the starting position and walk-in. Use the same straight line, pause at the same points and make no technical change until the entry itself becomes easier to compare.

A simple ten-repetition check

Perform ten no-hit repetitions on one straight line. For the first five, make no correction; record only whether the view is left, centred or right. If a consistent pattern appears, choose one small setup variable for the next five attempts.

After the comparison, remove the trainer and make a few normal practice strokes. SIGHTRIGHT is suitable for snooker, Chinese eight-ball and American pool, so the same observation routine can be used across those games. Its role remains the same: a visual reference before the shot, not an aiming system or a guarantee of accuracy.
