1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 0-0 5.a3 Bxc3 6.Qc3 b5!?
7.cxb5 c6
An interesting Gambit, which was played by Adams. Most players decline the gambit with 8. Bg5 and black regains the pawn with cxb5 .  Taking the c-pawn seems to be risky.
-7....a6!? seems to be an interesting alternativ. Is there a refutation
What do you think of 6.b5!? I think that it's playable but white get's a small edge as usual.  Perhabs a good line for lazy players. 
Comments please
