Taking Out The Trash - Part 6 - The Latvian Gambit

A little bit of a warning here:  The previous 5 TOTT blogs presented fairly simple opening plans to combat 'bad' gambits.  This blog is slightly different.  Here, I am going to attempt to present a concrete (and very sharp) refutation to the entire gambit.  The lines are much more complicated than you may be used to.  

As usual, I must mention that I have not comprehensively covered all of black's options.  I have covered black's two main tries (8... Nc6, and 8... Nf6).  Therefore, the lines given here should be studied carefully if one plans on using them to score a theoretical win against the Latvian gambit.

And now, at the risk of enraging the tricksters I strive to refute once again, I present my dear reader with a wholly convincing refutation of 1. e4 e5 2. Nf3 f5? - the Latvian Gambit.
