Normally, for match play, practice on the course is permitted before the match begins.
If GV pennant rules disallow that, then the only practice permitted is that on a specified practice area, such as the practice putting green or driving range. No other practice anywhere else on the course is permitted.
The pennant rule quoted by Bumpy above relates to practice during a match.
Chipping back through the markers has nothing to do with it.
The relevant questions are:
- Was practice before the match prohibited by the pennant rules and, if so, at what penalty?
- Had the match begun (by teeing off on the first allocated hole of the match)?
If the match had begun and this was between holes, the player is allowed to chip in the vicinity of the teeing ground providing he does not delay play.
