Press [A] only once and let the bars totally fill. Your player will throw the ball all by himself and you will have a 100% strike all the time. if you do not have a strike, then aim slightly to the left or right until you find the correct spot.
Select the character with the red shirt and give him no Power, full Curve, and the rest Accuracy. Pick the 20 pound ball that looks like a pirate's ball. When you first start out on the alley, keep pressing the right arrow until it is on the left side, so that it is going into the gutter. Then, press [A] and move it all the way over to the right. Put it at about 100 Power and full Accuracy. You should get a strike.
