This is what I also do.

I used to like this opening. But, I am stepping away from this since after 3...a6, white's forced to exchange B for N.

'Classical Defence'. So sensible does this look, you'd think it was one of the main lines, eh?

This is what Jack played against me. But, as reversion pointed out, it's not so good for black. Better is 3...a6, or the Berlin Defense, 3...Nf6 with which, they castle.

I used to play this, but I learned that after 3...Bc5, best is to respond with 4.c3, as it allows 5.d4, and after you exchange pawns, the B is attacked.

Interesting.

As would I here.

Why not.

As do I because it captures toward the center.

What about 7...d6 and after the Ne5 retreats, 8...d5 is still an option, with which, the Bc5 is only blocked a move. But, to me, that'd be worth it for the gain of tempo.

This is one occasion in which ...h6 would be disastrous, after 9.Bxf6 ... [A] 9...Qxf6 10.Nxd7 Qxb2 11.Nd2; or [B] 9...gxf6 10.Qg4ch .Kh8 11.Nxd7 Bc8 12.Qh5 Bxd7 13.Qxd5 - with 2 pawns ahead for White, and all 6 Black pawns are isolated.

True. I like this move the best. At first glance, 8...Be7 looks good, but I'd find it a bit passive.

As do I.

I agree with Fritz. As I was taught that the reason why 4.c3 is so popular after 3...Bc5 was attacking the B which works. But, it's especially useful in a position like this. I remember because in a game against Coach Stockel, I played Nc3, but c3 would attacked the B right away, as reversion also pointed out.
