1. False: The reason many beginning players start with doubles is that they find some security with a partner and gain some confidence on the court. Some doubles players remain doubles players throughout their careers: Caroline, Ilona, and Anna last season; Aleksa and Angela in 2017. It's a separate set of skills involving an understanding of the court, of angles, of coverage, etc.
2. False (mostly) A baseline player in a long, lobbing doubles point may run much farther than a singles player with less court to cover and probably a quicker point. It is true that a net player may not move during a point, but that's because she doesn't understand her role.
3. True. There is a lot to talk about: where on the court you will play, which opponent is better, which opponent is the weaker server, the stronger net player, more likely to make a mistake, etc. More than that, it's important to keep each other's spirits up, to feel you're not alone out there; otherwise it's like playing singles on a doubles court against three opponents.
4. True. Why would you want to start off by losing a game?
5. False, On the deuce side, stand about halfway between the mid-court hash mark and the singles sideline. Adopt the same principle same from the ad-court. This allows you to cover the corners on an angled return.
6. True, but with a caveat. If you missed the call and your partner is sure of that fact, she can and should overrule you. Don't take it personally: we all miss calls. It's better to correct an obvious mistake than to let your opponents think you're playing dishonestly.
7. True. You may not switch sides or serving order during the first set, but between sets, you may.
8. False. Get out of the way.
9. False. If the ball is out, it's out. What happens after that is irrelevant.
10. You're joking, right? You are in this together—survivors of a shipwreck—one of you rows, the other bails. Eventually you'll rescue yourselves. Or not.
