Mario Power Tennis: victory against an ace character!!

I didn´t do it: it was played by the almighty DaNieL!! (yes, my brother, DNL for short). Winning against the cpu at high difficulty levels is near impossible: i can´t beat it on the second most difficult one, so let´s not talk about the highest, the "ace" level (it is shown in the vid. It´s called master maestro in the spanish version because... well, i am spanish) The COU doesn´t control so well all the chars, as it is relatvely easy to win against an ace yoshi, but near impossible to beat other like donkey kong or paratroopa. My bro plays against an ace fly guy (mid difficulty) and manages to beat him... just watch him taking advantage of flyguy´s failures, and beating him... just incredible to me... man i am so bad at this game :_(
