Lines where black plays f6

If I remember correctly, MCO15 has the line, 1 e4 e5 2 Nf3 Nc6 3 Bb5 a6 4 Bxc6 dxc6 5 Nc3 f6. I think that there is also 1 e4 e5 2 Bc4 Nf6 3 Nf3 Nxe4 4 Nc3 Nxc3 5 dxc3 f6 (or something like that).

Another Ruy Lopez exchange, f6 is best and only:

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O Bd6 6.d4 exd4 7.Qxd4 f6
