Taking Out The Trash - Part 4 - The Blackmar-Diemar Gambit

In your chess career you'll likely find certain players, usually trapped in the 1400-1600 range with no hope of improvement, who absolutely insist on giving up material.  The Blackmar-Deimer gambit appeals to these players, as there isn't really a great way to decline the gambit without transposing into a French (and your opponent likely has some gambit prepared there too...).  The great thing about facing the B.D gambit is that it's just a bad opening!  

Let's check, I suggest you pay special attention to the variation 8. g4, as many white players will try it, but black has a beautiful refutation.
