B10: BriskerGolf: Green-side, Tee-side, and the Natural T-G Line. Leading to Brisker Golf
When no Green-side hazards (sand or water) exist on the Tee-Side edge of a Hole, then the division between Tee-side and Green-side regions on a golf hole, the T-G Line, is an imaginary line that skirts the front edge of the green (the Tee-side edge), and that travels the complete width of the Hole, on manicured grass and rough, without encountering any Green-side hazards (sand or water). This is called the Natural T-G Line, (or Default T-G Line).
Tee-side in this instance is the region from the Tee to the Natural T-G Line.
Green-side in this instance is the region from the Natural T-G Line towards and including the green and its surrounding area, to the limits of the side and rear boundaries of the hole.
Note that pockets of @Tee-Side areas often exist within @Green-Side and are termed Invasive Tee-Side regions.
A ball in any @Tee-Side area may never be marked, and must be played before any @Green-Side ball regardless of its distance from the Pin.
Invasive Tee-Side regions are the following areas within @Green-Side:
- Water Hazards
All the above Invasive Tee-Side lies may be freely re-placed (not dropped), at a location not nearer to the Pin, by virtue of the generous OOBLU* rules, [Out Of Bounds, Lost, Unplayable rules]
Note that all balls lying in Tee-Side areas, including Invasive Tee-Side areas, must either be played onto @Green-Side or picked up, before any @Green-Side play begins.
