I don't know how to type German, but the U should have an um lout over it:
Tubingen Gambit (1.Nc3 Nf6 2.g4) and Yes, ABSOLUTELY, it's sound.
Lolli Gambit (1.e4 e5 2.f4 exf4 3.Nf3 g5 4.Bc4 g4 5.Bxf7+ Kxf7 6.O-O gxf3), and ABSOLUTELY NOT! I don't even find the King's Gambit Sound, and SURELY this ain't sound.



What are the weirdest gambit names you ever heard of and do you think these gambits are sound?
