If one of your balls has no shot at any of the other 3 balls and
your opponent is responsible for its position, you can lift it and play it from
either baulk.
To 'have a shot' your ball must be able to hit either side of another ball.
In the diagram you are Black and Blue. Your opponent has broken down at 2-back with Yellow.
Your Black ball is for hoop 1 - what do you do?
Answer: Claim the wiring lift.
Black is clearly wired from the 2 further balls but is also wired from Yellow (although Black can clearly hit Yellow it cannot hit the right hand side of it).
Lift Black to B baulk and rush Red to hoop 2. Take off to Blue and then to Yellow.
