I started playing the Hammerschlag (1.f3 e5 2.Kf2!), which is one of the "unofficial" Bongclouds listed in the ECO; but the Bongcloud seems better!
P.D: I would like to add the Pawn Advance variation In Alekhine's Bongcloud:
1.e4 Nf6 2.e5!? (not as good as Ke2, but still good) Nd5 3.Ke2
Looks solid to me.
After reading a bit of this thread, I went onto live chess and faced the bong cloud for the first time. My opponent had the advantage but didn't protect h2 or attack f7 and I managed to pull off the win. I was lucky
