Make sure you follow the correct procedures in playing 2 balls—1: decide before taking any action, 2: declare which ball you want to count as score, 3. MOST IMPORTANTLY, let committee know you played 2 balls even if you score same with both balls.
I am amazed each year as to what players do not understand about the rules and I’m talking about just the basics, not the complicated ones. I’m interested to see what Local Rules the WA decide to use. Most people that do not play in other tournaments will assume the local rule a lost ball or ball OB, is a Rule and not the Local Rule it is.
