It’s a good language for quickly talking about differences of opinion about the motivatedness of an idea or conceptual attack. Someone might think one of your moves is ? where you think it’s !?, or ?? instead of ?!, or !! instead of !?. It’s not uncommon for moves you initially think are ?! to end up being ? or ?? upon further examination. Initially !?-seeming moves tend both ways.
