The ICBM

The ICBM, a nice opening trap to win a queen.

This is only a follow up from the Scandinavian - Tennison gambit, which for me, I think is pretty rare.

Even if the opponent doesn't fall for the trap you still get many advantages through center control and early development. 

Here's an example.

It still often works though, and when it does work, the results are devastating.
