Doubles in blackball

To make a double, picture the rebound point on the cushion as the mirror image of the pocket, then play towards that mirrored point with moderate power.

Schéma de la situation

Why this situation is tricky

A double bounces the object ball off a cushion before it goes in the pocket. The rebound angle depends both on the contact point on the cue ball and the angle at which it reaches the cushion, which multiplies the sources of error.

The method

Picture the rebound point on the cushion as if the target pocket were reflected on the other side of the cushion. Then play normally towards that mirrored point with moderate power: a double hit too hard amplifies angle errors on the rebound.

In blackball, the softer cushions send the ball back at a slightly different angle than in snooker, where firmer cushions make the rebound more predictable once the technique is mastered.

What repetition changes

The double is a shot most players avoid in a match for lack of confidence. By repeating it with Sniper, you test several rebound angles on the same setup and gain the confidence to attempt it in a match.

Frequently asked questions

How to make a double?
Use the mirror principle. Picture the target pocket reflected on the other side of the cushion, as in a mirror, then play the object ball towards that mirrored point: the angle into the cushion and the angle out of it are then equal. This reference only holds under two conditions: a centre-ball strike and moderate power. As soon as you add side or hit firmly, the rebound stops following the model. So always start by playing the double with centre ball at medium pace, and only adjust once the basic reference is in place.
Why does my double always come up short or long?
Because two factors change the rebound angle, and they are rarely neutral. The first is side spin: running side, in the direction the ball is travelling along the cushion, widens the angle out; reverse side shortens it and slows the ball. The second is power: the mirror model assumes a moderate pace, and straying from it distorts the rebound. So if your doubles consistently finish on the same side, the fault is not in how you picture the rebound point, but in unintended side spin or in hitting too hard.
Does a double work the same way in blackball and snooker?
The geometry is the same, the margin is not. The mirror reference applies in both games, but cushions and pockets do not behave identically: in blackball, more generous pockets accept a ball arriving slightly off line after the rebound, whereas snooker's cut pockets reject it. Add the length of a snooker table, which extends the path after the rebound and magnifies any angle error, and you get a noticeably more demanding shot from the same reference.
When should I attempt a double in a match?
When there is no reasonable direct option, and only after weighing what the shot leaves behind if it fails. A double remains a shot with several sources of error: contact point on the cue ball, angle into the cushion, power. It is justified when the object ball is blocked for a direct pot, when a miss leaves your opponent in an awkward position, or when the score demands it. In practice, though, it deserves to be drilled for its own sake: it is a reference shot, and a reference is only built by replaying it.

Start repeating

Sniper resets the ball in about 2.5 s, so you run this drill far more times than in a regular game.
