Cue, if ballA is slightly left of sidepocketS,
and I want to pocket ballB in sidepocketS using
cueballC, both B and C being roughly positioned
as shown, and all shots must be fully called,
then it is easier to call "ballB in the side
pocket, kiss off ballA" ..... agree?
And you'd chalk your cue before shooting, of course...
