The Classical Defence (3...Bc5) has proved difficult for even top players to handle succesfully:

Short vs Kamsky, 1994
E Jimenez Zerguera vs Fischer, 1960

<11.Ng5> Nxg5 12.Bxg5 Qe8 13.d6 Ng6 14.Re1 Nxe5 15.Bc4+ is also strong.

Black finds it difficult to organize counterplay aginst White's centre, especially in the face of the threat of the <d6> advance. Unfortunately, playing a preventative <11...d6!?> is not advisable 12.Nxe4 fxe4 13.Bxe4 dxe5 14.Nxe5 with advantage

<12.d6!> cuts Black's position in two, and he does not recover.

<13.Nc4!?> may be even stronger, 13... Nxd3 14.Nxb6 axb6 15.Qxd3 c6 16.Qb3+ Kh8 17.Ng5 winning

<17...h6> may have been a better defensive try 18.dxc7 Bxc7 19.Nxe4

<18.Nxh7> is an alternativce way of progressing the K-side attack 18... Nf3+ 19.gxf3 Kxh7 20.Bxe4+

<has proved difficult for even top players to handle succesfully:>

E Jimenez Zerguera vs Fischer, 1960

Fischer has no problems in that game.

However, I agree that the Classical variation favors white.
