Center ball english ( c ). It is possible, to have an infinite # of cueball contact points, for example; if you had moved your tip 1/1000 of a millimeter to the right from this center ball hit, it would be possible for 13,000 different hits to move a 13mm tip one full tip away from center. This is a factoid - however useless...

1 tip of right center ( rc ); Used preferrably to cinch an ob I happen to be cutting a little left, or when banking an ob ball a little left...

3 tips toward 3 o'clock. This is maximum right spin, not counting a masse' of course.

Ob spins 1 tip toward 4 ( ob loses 1 tip of spin in transference ).
Cb goes further through the obcp than would be the normal c to c where they meet deflection, the cb then fights to spin left after hitting a rail...

10:30; The perfect equal amount of left spin and follow, by this I mean, neither are dominant, the cb will transfer 4:30 spin to the ob, which is another perfect combination of right spin and draw.
