Advanced Pool Drills With Diagrams: Three Tests

Make the Difficulty About the Next Shot

Advanced pool drills with diagrams should test whether you can reproduce useful cue-ball routes, not merely pot difficult balls. Use fixed layouts, called landing areas and a score that distinguishes a pot from position that genuinely preserves the next shot.

The two diagrams below use a 100 by 50 table: x runs from the head rail to the foot rail, and y runs between the long rails. A diamond is 12.5 units. Coordinates describe ball centres and landing areas approximately; use the diamonds to reset them consistently without treating the drawing as a full physical simulation.

Start with the layouts as shown, then adjust the challenge only after recording a baseline. An advanced task need not include extreme spin or a spectacular recovery. Repeatedly retaining the correct angle through a modest window can be more demanding, and more useful, than making one impressive pot after several unrecorded retries.

Test a Stun Route Into a Window

Layout One: Separate Line From Distance

In the first diagram, the object ball at (75, 12.5) goes towards the foot-top corner at (100, 0). The cue ball begins at (50, 12.5), creating a cut rather than a straight shot. The drawn object path is a reference; the contact point must still be found from the actual ball sizes.

For a stun collision, the cue ball initially departs along the tangent line, towards the lower-right region in this layout. Choose a pace that brings it into the marked rectangle before the cushion. Count the attempt only if you pot and finish in the window without scratching. Record which side of the rectangle you miss.

Use Angle, Not Straight to extend the idea to a next-ball requirement. A cue ball that lands in a box can still leave an unsuitable angle. Once the basic route is repeatable, place a second ball and redefine success as a pot, a window hit and the intended side of that ball.

Use the Geometry Before Adding Spin

The tangent-line explanation is the starting reference for the first layout. A cue ball sliding without forward or backward roll at contact initially departs approximately perpendicular to the object-ball path. If it arrives rolling instead, you should expect a different route rather than blaming your speed judgement alone.

Call the intended cue-ball state before each attempt: stun, rolling follow or draw. Then change only pace within that chosen family. Trying low, high and side contacts interchangeably while chasing one rectangle prevents you from learning which part of the route changed.

Use the interactive path tool to compare the broad options, then test them on your table. It is a teaching reference, not a promise of a precise endpoint. Cloth friction, ball condition, collision details and cushion response affect real shots. If the desired window demands a very delicate contact state, widen it or choose a more forgiving route before narrowing it again.

Compare Two Routes Through a Second Layout

In the second diagram, begin at (35, 35) and pot the ball at (50, 12.5) into the top side pocket. The next ball is at (75, 25). The shaded central-right area is a suggested starting target, not an instruction to use one particular spin combination.

First inspect the shot while standing and identify a direct cue-ball route. Then consider whether a cushion-assisted route could approach the same general area with a larger distance margin. Do not assume the extra cushion is automatically safer. Compare scratch lines, traffic and the angle left on the next ball.

Play five attempts with each chosen route, resetting all balls. Score pots, target-area finishes and playable next shots separately. You may discover that a wider landing area outside the drawn rectangle offers a better next shot. If so, redefine the target before a new set rather than awarding yourself extra credit during the current one.

Add One Constraint at a Time

When both open layouts are manageable, add a single blocker to remove an easy route. Position it so the object-ball pot remains possible and you are testing cue-ball planning rather than an accidental snooker. Sketch or note its coordinates so the next session uses the same obstacle.

Another progression is to narrow the landing rectangle while leaving the balls fixed. A third is to require the next pot from the achieved position, with no ball in hand. Choose one of these changes, not all three. An exercise that becomes almost impossible tells you little about which demand caused the breakdown.

The Position Box drill provides another scored way to work on landing areas. Use its stated dimensions and scoring when comparing sessions. Custom layouts are useful for investigation, but standardised drills give you a clearer reference when table time is limited or when several players want to compare the same task.

Finish With an Unseen Position Test

After the repeated work, move the next ball to a different open location and plan one attempt without rehearsal. State the desired pocket, contact state, route and landing area before getting down. Then play the first shot and assess the actual next shot without adjusting the cue ball.

Use the 9-ball position progression if your main difficulty is retaining the correct angle through several compulsory balls. If you can plan sensibly but repeatedly miss one side of a narrow window, keep the current layout and investigate the delivery or distance error instead of collecting new patterns.

Record the setup version, target dimensions, attempts and results. Add one sentence explaining why your preferred route was more forgiving. A good advanced session improves both execution and your ability to justify a decision. The aim is not to prove that you can solve a diagram once, but to find a route you would trust when the next attempt is the only one available.
