Hehe the stoners option. 
how about this- strangest looking opening that is actually a good opening? mainline caro-kann maybe
The Alekhine's Defense has always looked strange to me. Some variations are almost comical looking. The four pawns attack is: 1.) e4, Nf6 2.) e5, Nd5 3.) d4, d6 4.) c4, Nb6 5.) f4. Here White has four pawns in the center. Meanwhile Black has moved his Knight three times, and does not have a pawn in the center.
I'm guessing your kidding, but if not how is that black is lost here??
