I had a match today on a team I don't captain. Players on adjacent court started having a huge argument. My partner asked me what we should do, and I said we should do nothing, they have to work it out. On and on the argument went. Finally, one of the players came over to us on our changeover and asked what they should do if they disagree on a rule. I said you have to work it out yourselves. The player said, "We've tried that. We can't agree. Is that a pro? I'll go ask him." I said, "You can't ask anyone. I have the rules in my bag if you want to look it up." She said, "We've already looked at the rule and there is no rule in what we have." I said, "Well, spin a racket and winner decides how you'll proceed." After all, we play timed matches and cannot spend all afternoon researching rules. After the match, they told me the problem. They were playing a tiebreak, and a player served her first service point from the deuce court rather than the ad court. They played the point. Someone realized the error. Does the server serve to the ad court or the deuce court for the next point? Do they disregard the errant point entirely and go back and do things correctly? Or does the server serve her second point to the same returner who struck the first return, thereby fixing things as soon as the error is discovered? I am too lazy to look it up, so I am hoping someone will know the answer. I remember reading this in the rules, and struck me as very complicated. My gut says that the server should serve to the other player, to avoid having the same returner hit two returns in a row, and the point played in good faith stands. True? False? In the lobby, someone asked what would happen if a player realized the service error mid-point and caught the ball and declared a let. I didn't know the answer, and thinking about it gives me a headache.
