I am new to tennis, both as a viewer and a player. I hope this is not the wrong place to ask a beginner question.
So what happens is, after serving the ball I am too invested in the game and I don't remember which side I served from last. That means I can't figure out where to serve from next. This is also true for when I am on the receiver end. I can't figure out which side of the court to stand on.
I couldn't find any trick for this on the internet after a quick search. How do you do it? Is there a way to "calculate" the service side from the current score?
