Blackmar Diemer Gambit
Cult following openings

I'm trying to start a 1...Nc6 cult. You will win all your games with black, but you have to send me all your money.

I thought cult opening signified an "inferior" opening with fierce devotees. We have seen KG at top levels recently.

@11 You can use that to say any opening isn't inferior. Sometimes they are played because they think the opponent won't be well prepared, not just because it's the most theoretically challenging.

I agree with Graywacke, I have a fetish with the Pirc. I don't play her (yes, her) nowadays, I think she needs a lot of time to be devoted, but I'm sure I'll be back with her any day.
What are se openings that have always had a bit of a cult following ?
