This is the sixth article in a series on fundamentals. In the last five months, I've covered the
stroke, the basics of aiming, issues involved with cut-shot aiming systems, the effects of bridge
length, and the basics of cue ball (CB) control. This month we will look at some examples of how
to apply the CB control principles covered last month. We will look at examples of how to avoid a
scratch and how to plan and execute carom and break-out shots. Recall, the 90 rule predicts
that the CB will head straight in the tangent-line direction for a stun shot, where the CB has no
topspin or bottom-spin at object ball (OB) contact. The 30 rule predicts a rolling CB will deflect
by close to 30, with respect to its original direction, for a wide range of shots. And the trisect
system predicts, for a good action draw shot, the final direction of the CB will be three-times the
cut angle away from the original direction (see last month's article and NV B.43 for more
