Re: tips for slices and lobs?
One tip for a lob, assuming you are not at a super high level, always go over the left hand shoulder of a righty and vice-versa. A backhand smash is infinately tougher than a regular smash for 99% fo players. Even if you don't get the lob perfect your opponent may well miss and is very unlikely to hit a clean winner unless they are an expert at that shot.
