Ask yourself this: what is the purpose of the 'call the ten ball' rule? Give it a moments thought and you will arrive at this conclusion - the purpose of the rule is to make it so that a player cannot win the game by pocketing the winning ball in a hole other than the intended pocket. That is why we have this rule. There is no other reason. We might call this 'The Spirit of the Rule', to take away false victories due to luck.
Now what happened in this game isn't what the rule was designed to overcome, because it is clear that the player is attempting the ball in the made pocket. This is so clear to everyone, even a beginner who walked in off the street, that the only gentlemanly conduct from the opposing player would have been to decline the foul.
The only sensible result of Biado's shot on the ten ball is that it should be declared the winning shot of the rack. There is the technical interpretation and there is what is clearly just, like in law sometimes the letter of the rule doesn't tell the whole story and the judge has to make a decision based on what the law is trying to achieve. This is so obviously to me a dick move that deserves to be heaped with scorn that I'm amazed that others can defend such conduct.
I think it just kind of shows who the pool hall lawyers are, those guys that are going to look for any technicality no matter how trivial or what the rule was meant for to pull a move.
