After 12.Bxc6 bxc6! black can play ...Bb6, c5 and protect his
weak pawn d4. This improves his position considerably, since
the white bishop on b2 leaves out of play.
12. a4 a6
12...a6? is a bad move since 13.Nd2 axb5 14.axb5 Qd8 15.bxc6 is bad
for heam. Black looses now his pawn d4 immedeatly. Better would have been
12...0-0 but white keeps an advantage:
12. Nd2
A) 12...Bb4 13.Nf3 Bc3 (this exchange is good for white) 14.Qc1 Qb6
15.Bxc3 dxc3 16.Qe1... Black has still no counterplay, white will
attack on the kingwing.
B) 12..f6 13.Nf3 fxe5 14.Bxc6 Bxc6 15.Nxe5
Now black has a weak pawn more and still no real plan.
