Chess Diagram: 


Game: 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qb3 c5 5.a3 Qa5 6.Bd2 Nc6 7.Qd1 Nxd4; during these opening moves we have already seen an aggressive play on Black's side, using the power of the pins. The result is an advantage in development by Black. Your tasks:
a) Name the opening
b) What happens if White takes the Bishop: 8.axb4 ...?
c) What should white do here? Play the best line you can think of.
