Try playing 11-7, it's better for you than playing 10-6. You'll find the weaker player player has a harder time when he has to make 7 balls as opposed to 6. I used to play this guy giving him 9-7 and I always won. Finally I started giving him 9-6 and it was a very different game, he came out ahead. We played 9-6 again and I played very well all night and we broke even. that one ball makes a big difference.
