What's a joke is your lack of understanding of how things work.
YOUR forehand might defeat me breadsticks, but it won't faze a 5.5, and Federer will pound it into a clean winner.
YOUR backhand might cause me to miss over and over again, but a good 5.5 will pummel you by going to your backhand every time.
YOUR serve might knock me silly on my butt, but a good 5.5 will just chip it into a corner you can barely reach, as you stumble and fall on your face.
What you call "POWER" might be just a rally ball for someone better than you.
