I hold the right button down when I am attacked thinking it will lower the damage I take (since your health bar travels left when you lose hp) and I hold down the left button thinking it will increase the damage done.. Well I used to think that at least, now it is a habit.. Also when trying to catch a hard-to-catch pokemon (legendaries), I throw the ball, rapidly tap a and b (a,b,a,b,a,b,) or sometimes (ab,ab,ab,ab) and if that doesnt work I look away from the pokemon (or sometimes I stare it down, like an intimidation thing), and turn off the volume...
