Its not that great at all.
The line 3.dxe5 d4 4.Nf3 Nc6 5.a3 is really good for white. People say "Oh Moro beat Topalov with it...." but that was a rapid game
You are not taking a decent d4 player out of their game using this just because it is sharper than say the QGD. Modern lines in d4/c4 can get very sharp and you need to prepare against them anyways! Yea, maybe if they were a Colle player this scares them, but in that case the Albin isn't even there!
The albin counter gambit is a great counter for black against the queen's gambit. So tell me what you like about this gambit, what you hate about it, main lines, counters, and games you've seen.
