could we get a "no play list" set up on the stairs games?  He has plenty of others he can invite to a game and he knows I don't want to play him.  He holds up games and is in general a pain.  If there is only one person on the tier, then playing them could be forced but if he has other choices, he should play them.   Otherwise maybe he needs to be banned from there as well.  It is afterall another form of a tournament.
