Maybe I'm just not on the same frequency as Simon, but I really don't think
of the Heortlings as people who go around crying "Blasphemy!" all that
often. I don't see their gods being offended that someone is playing a game
with their images; in fact, it might be a useful divinatory tool (though
probably not as good as the normal Orlanthi divination techniques). I also
don't think there's any danger identifying one's self with the gods, since
normal chessplayers don't identify themselves with kings and bishops, and
that each player is playing all the gods in a pantheon on a very abstract
level. YGMV, IMO, et al.
