No-tick free-guard zone explained
The Pinty’s Grand Slam of Curling will be using the no-tick, free-guard zone for the 2022 HearingLife Tour Challenge during the eighth and extra ends only.
During the delivery of the first five stones in the eighth or extra end, if a delivered stone causes, either directly or indirectly, an opposition stone in the free guard zone (FGZ) that is touching the centre line to be removed to an off-centre line position, the non-offending team has the option to:
(i) remove the delivered stone from play and replace all stones that were displaced to their positions prior to the violation taking place; or
(ii) leave all stones where they came to rest.
