Thanks Jay. FYI, I have a lot more examples of bad calls here:
I am pretty sure I remember you commentating on at least one of the examples linked on the page linked above, but I can't be sure without watching all of them again (which you can do if you are interested).
It is an illegal shot only if it is a "
double hit" (e.g., if there is a gap between the balls), a "
push shot" (e.g., if the tip is touched to the CB first), an
intentional miscue, or
any other foul.
Since hitting into a frozen CB with a normal stroke involves a single clean hit with no push, there is nothing to make the shot illegal, unless there is a "special rule" that prohibits frozen-CB shots (which is not the case currently). Was that the case in the past? Was there a rule that explicitly prohibited frozen-CB shots?
For explanations (including super slow motion video) for why frozen CB shots are allowed, see the videos and info here:
