It is equivalent to AM for all three-candidate cases, and Chris did not
specify what AM was with more candidates, so AMS is indeed a possible
version of AM. So are Beatpath(AM), Ranked Pairs(AM), and River(AM), and
I wonder which of them, if any, is equivalent to AMS. From the
construction, I guess it must be possible to decide whether AMS is
"immune from second place complaints", which will help answering that
question since Beatpath and River are not, while RP is.
