I know that when you start a match, you spin the racket or toss a coin and decide who serves first and who goes on what side. If you finish a set that's not a multiple of 4, say 6-3, does the person who served last now receives?
Example: Person A serves first on side 1. They keep on playing. Say A wins the set 6-3. A served in the last set on side 1. In the next set, do they swap sides and Person B serves on side 1 or does A serve again on side 1 like the start the first set?
I'm pretty sure it's the first option but when I play some people say you spin the racket again or start again like a new set. When they do it my way, they get confused when to swap sides because the rely on the number of games played, and they don't count the first set.
