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.
