Huh, actually not a bad gambit now that I check it a bit more with Fritz.

What do you think? I think Black is equal.
@yereslov. Your line is certainly interesting, but I feel that black would simply take on c3 after a3 and play Qc7 or cxd4, transposing into the poisoned pawn variation of the winawer.
Yes, that makes sense.
Something like this came up in my tournament game recently. I was black.
Here's a better variation:
Oh, never mind. 9.b3 destroys the whole thing.
What about Qb6 after Bb5?
