You missed quoting the part where I describe the on clauses you need to
distinguish between "them" and "me"

Me: u.uid in (player...) and (s.uid = u.uid)
Them: u.uid in (player...) and (s.uid <> u.uid)

In particular, the IN expression causes two rows to be returned, one for
them and one for me - but for each join you only want one or the other.
