In snooker, push shots and double contacts are not allowed. This particular unfouled push foul was performed by David Lilley in a 2024 Championship League match. Referee Ben Williams missed it.

There is a very simple formula that all referees can use to identify a double contact: Quite simply if (A) the distance the cue travels through the white is greater than (B) the distance between the two balls then it has to be a double contact. This is because the white will always slow down when it meets the object ball and this allows the cue to catch up for a second contact. (This all happens in a split second of course.)

And because the object ball went in the hole we can also assume that the second contact is a push, that is: The cue contacts the white exactly when the white is contacting the object ball. If it wasn't a push then the timing would have been off and the ball would not have gone in the hole.

In the video, A is clearly greater than B. This is a push.

The white also gives a little jump which confirms the second contact as the ball rolls over the angled shaft of the cue.
