Baltic Defense Refuted

Because I had just played a game where my opponent played the baltic defense and I had heard that this was a defense that had been refuted, I began searching for it. However, all I could find on search engines were win %s and claims that a certain book had the refutation. So instead of purchasing a book to win a single online game, I decided it would be good training to look at the opening and try to find the refutation myself!

After being beat with this opening in live chess, I understood some of the basic ideas... This is what I came up with after a bit-o-work... Pls say something if you see an issue OR if you know the refutation yourself.

The Budipest gambit wins a queen too.

If it wouldn't be too much of a bother, would you pls post the line that leads to the queen capture?

Yes. I'm obviously kidding. This is just the main line after the first 10 moves

lol, well i am too, you can't refute an opening based on one line, I'm just showing what i think of the MAIN line.

6...Nf6 is a mistake. Better is 6...e5. Immediately placing pressure on d4. Does anyone know what to do as Black after 3.Qb3? So, 1.d4 d5 2.c4 Bf5 3.Qb3. What's Black's best move?
