I am not sure, what "full" means here... Should I try to send the birdy as far as I can? Or I am only allowed to use the whole strength, but it is not necessary? If my opponent says, the birdy is too slow, because he can't send it to the doubles line according to 3.2. But I guess, he doesn't apply himself to 100% intentionally, or even if he actually does... I am able to strike it so hard, and say - it's not my problem, the shuttle is correct. Who is right?
