[For other posts about the 2020 rules and changes to the rules, see THIS.]
The FIPJP rules have changed. Article 7 of the 2020 version of the rules makes dramatic changes to the rules about where the circle and the jack can be thrown or placed. Basically, the new rules specify minimum required distances from three things— boundaries, other games, and obstacles.
Previously, the rules defining the landing strip were quite complex. Now there is only one simple rule. The jack can be thrown or placed anywhere on the assigned lane, except within 50cm of an end (short side) of the lane.
There is no longer any requirement that a jack must be a minimum distance from a side line or a dead-ball line. As long as the jack is touching the ground of the assigned lane, it is valid. It can touch a side line, and even extend over it, and still be valid. (A thrown jack is not like a hit jack, which can be resting on ground outside the dead-ball line and still be good.)
The rule now is simple. The circle and jack must be at least 1.5 meters from any other active circle or jack.
Formerly, the circle and the jack had to be at least 1 meter from any obstacle. The distance for the jack was reduced to 50cm, so now the minimum distance from an obstacle is different for the circle and the jack.
- The circle must be at least 1 meter from any obstacle.
- The jack must be at least 50cm from any obstacle.
Worst-case scenarios under the new rules
The new requirement that the jack must be at least 1.5 meters from any other active circle or jack, has raised concerns that it would create problems, especially when playing on a narrow 3-meter-wide lane.
One worst-case scenario occurs with active jacks in neighboring games kissing the boundary strings on both sides. The full width of the lane is available only if you throw the jack to 6-7 meters. There is no place on the lane where you can throw the jack to 8.5 meters. (In this diagram, pink areas show the landing strip for the jack.)
Perhaps the very worst scenario is this one. The neighboring jacks are offset from each other, so that there is virtually no place where the landing strip extends the full width of the lane.
Obviously, such situations will be extremely rare. But they are possible.
