<P> The curler can induce a curved path by causing the stone to slowly turn as it slides , and the path of the rock may be further influenced by two sweepers with brooms who accompany it as it slides down the sheet , using the brooms to alter the state of the ice in front of the stone . Sweeping a rock makes it curl less , and decreases the friction that slows the rock down . A great deal of strategy and teamwork go into choosing the ideal path and placement of a stone for each situation , and the skills of the curlers determine the degree to which the stone will achieve the desired result . This gives curling its nickname of `` chess on ice '' . </P>
