@Eric That might be true to a point, but don't dig up something too old or too dubious... you will just get faceslapped. A master I beat about 2 months ago, he was told I played 8. Rb1 and knew the theory well. He decided to deviate with a dubious line from the 80s. He was lost right out of the opening and never got a chance to even play a game.
Well, my first criteria is always soundness. I would never play anything unsound purposely. Well ok, maybe if I was already in a very bad position and thought creating complications was my best chance, but you know what I mean.
But people are way too obsessed with main lines and playing whatever is in the latest book they buy. I mean, think about the King's Indian. As White, you could play the Classical, the Four Pawns Attack, the Saemisch, the Averbakh, The Fianchetto...these are all sound and "main lines". And within each system there are choices, like the Classical with 9.Ne1, Nd2, b4, etc. I get annoyed at the obsession to play the absolute sharpest, latest fashion. Take John Cox's repertoire in Starting Out: 1.d4 (an excellent book, btw). What are the chances, ask yourself honestly, that the Bayonet vs. the KID, the 8.Rb1 Exchange Gruenfeld, the Exchange QGD, 7.Bb3 against the QGA, the main-line Botvinnik Semi-Slav, 4.Qc2 in the Nimzo, etc., are all perfect openings for you? Not very likely, I'd wager. And there are plenty of choices out there that are still "main lines."
Then again, there are people who are afraid of anything with main line status and play a bunch of junk just to avoid them, which is probably what you're warning against.
