This is quite comical....
The most unknown chess opening of all

I happened to pick up a copy of "Unorthodox Chess Openings" (Eric Schiller) recently and found it fascinating, so I'm in the mood to post a couple obscure though possibly sound openings from that book...

These openings....

I've played the "Tubingen Gambit" (the "u" should have an um lout over it, or whatever you call those sidewards colons in German) about 5 to 10 times over the board:
The Diagram Thingamabobber is not working today (some kind of scripting error), but it's 1.Nc3 Nf6 2.g4.
There are a number of variations, but Black's best is to directly transpose to the Bronstein Gambit (1.d4 Nf6 2.g4 Nxg4 3.e4 d6 4.Be2 Nf6 5.Nc3) via 2...Nxg4 3.e4 d6 4.Be2 (4.d4? is a mistake because of 4...e5!) Nf6 5.d4, leading directly to the same position listed above in parenthesis.
Post the most unknown opening that you feel actully isn't junk. Bonus if there are traps existing in them.
What I don't want but I guess you could do....
So yeah.
