Rory did it, so did Westwood and Goosen, and probably all of us – infringe the Rules of Golf unintentionally. The R&A states that there are some 300 hidden Rules in the Decisions on the Rules of Golf book, so the major revision for 2019 slides those into the normal rule book and concertinas the Rules from 32 to 24.

Such a wholesale revision has not been seen for decades and we will all have to learn new terms – penalty area; no play zone; general area; general penalty; relief area, etc.
