Draw
Draw, sometimes called back-spin or "bottom," is backward spin applied to the cue ball by hitting it below the midpoint of its vertical plane as it faces the shooter. If the cue ball is hit with draw, and if that spin remains on the cue ball at the moment of impact with an object ball, the cue ball will reverse direction on a dead-on or center-to-center hit, and "draw" backwards. Draw is referred to in the United Kingdom as "screw" or "back-spin".
Draw applied to a non-dead-on shot will cause the angle of departure of the cue ball from the object ball to narrow shortly after impact. Similarly, it will cause a narrowing of the cue ball's rebound angle after impact with a rail cushion.
Draw can also be used to slow the rate of cue ball travel as a result of increased friction between the cloth and the cue ball. This is often called "drag draw".
A cue ball with back spin can impart a small amount of follow to the object ball. This is often useful in close combination shots to make the first ball struck follow instead of stun after second ball contact.

Famous quotes containing the word draw:
“As kingfishers catch fire, dragonflies draw flame;”
—Gerard Manley Hopkins (1844–1889)
“I always draw a parallel between oppression by the regime and oppression by men. To me it is just the same. I always challenge men on why they react to oppression by the regime, but then they do exactly the same things to women that they criticize the regime for.”
—Sethembile N., South African black anti-apartheid activist. As quoted in Lives of Courage, ch. 19, by Diana E. H. Russell (1989)
“It is sometimes well for a blatant error to draw attention to overmodest truths.”
—Jean Rostand (1894–1977)
