I spent 3 weeks trying to figure out how to play this pattern. I stumbled on to this website and studied the tweener instructions. A gentleman at my local center helped me apply this and I went from avg 160 on this pattern to 207. It was all about the angle. I kept throwing my shot like I would a house shot since the pattern was similar in length. I moved 12 boards inside and started throwing over 5. I dominated my PBA experience league that night and scored 1037 over 5 games.
