sentence: Deflection is an undesirable effect from the use of sidespin.
sentences_before: The stick used to hit billiard balls, called a billiards cue, is different in some ways from the typical pool cue. These features make the billiard cue stiffer. This stiffness helps players in striking the larger and heavier billiard balls as compared with pool balls.
sentences_after: Sidespin is spin placed on a ball by striking it not at its center but off to one side of its center, causing it to spin as it travels down the table. Deflection causes a ball to travel not in a straight line in the direction it was struck.
