Is it an infringement of the rules for your opponent to be standing directly behind you or in front down the line whilst you are putting?
I always thought it was but have have been trawling through the rules book, as you do, and I can't find it within the rules.
The only place it seems to be covered is under etiquette
Consideration for Other Players
"Players should not stand close to or directly behind the ball, or directly behind the hole, when a player is about to play"
Is this right? Perhaps one of the rules gurus on here can let me know and point me in the right direction.
