Underarm serving

Yes, you are allowed to serve underarm, and no, you don’t have to announce your intention beforehand. But beware: your opponent may accuse you of trying to take an unsporting advantage. Famously Martina Hingis once had some success with this tactic at the French Open. She won one point that way but eventually lost the match on an underarm double fault and left the court in tears. Tennis karma at work?
