Hey, I just took up squash in the winter season. I was wondering if anybody is familiar with the rules. On the serve is it okay to serve overhead? And can the serve hit the backwall or is it only good if it lands on the floor of your opponent's box? To wrap this thread to tennis in some way; I really suggest taking up squash. It's great for tennis, footwork skills are very similiar if not more rigorous and there is large amount of "wrist flicking" required, which helps you hit similar flicking shots in tennis when you're on the run.
