Essent 2004 saw Carlsen as White losing badly to this line: 1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Bf5 5.Ng3 Bg6 6.h4 h6 7.Nf3 Nd7 8.h5 Bh7 9.Bd3 Bxd3 10.Qxd3 Ngf6 11.Bf4 e6 12.0-0-0 Nd5 13.Bd2 Nb4 14. Qb3

It looks like an interesting, even attacking  ??? ,  try for Black. What do the Caro experts here think? Gallagher in his book says White can establish a slight edge with both 14. Qb3 and 14. Bxb4. But I doubt this, the first move received a drubbing in the carlsen game (see below), the second move gives up the bishop pair a bit too quickly.
