Pot 2 colours

[murke]

Hi everyone!

My friend thinks he's found an ambiguity in the written rules when 2 colours are potted.

For example when just the black and pink remain, the cue ball hits the pink and then the black, then the pink drops, then the black drops.

Has this happened in a professional match? Unless I can find a real example it will be very difficult to convince him that this is definitely a foul 😂

See rules 2.11, 3.3(h)(iii) and 3.11(b)(iii)

After the reds are potted, the colours become 'on' in ascending order. A colour can't become 'on' on the same turn that the previous 'on' colour is potted. Same as if you pot a red and colour with the same stroke it's a foul.

Thanks, I agree. But where does it say in the rules exactly when the next ball becomes "on"

One of the parts you mentioned says the colours become 'on' in consecutive order. A ball can't become on half way through a shot, it has to he 'on' when you strike the cueball to be a legal stroke.

Thanks, is that explicit in the rules somewhere?

One bit which does make it explicit is when you apply the definition of potting vs pocketing in the rules and apply that to the sections you quoted. If a second colour went in a pocket after the ball on it would be pocketed rather than potted, and would therefore be a foul

Exactly.

The original poster's scenario, with the black being potted (instead of 'pocketed') right after the pink, but in the same shot, cannot be correct. If it were....

ANY shot, splitting the pack let's say from the blue, would be correct if a red fell. You just happen to be on color again, instead of read, as long as the blue dissapears just a fraction before the red does (which it will, given the angle, power... of the split). Ref counts "one, ... six-seven, ..." and you declare black next?

Would be the same. AKA not OK
