Apropos of 2.Bc4, I've been playing some Scheveningen games with 2...e6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6.  What to do after 3.Nc3 is a problem, since for example, 3...Nc6 4.d4 cxd4 5.Nxd4 e6 6.Be3 Nf6 7.Bc4 and I have to face a Sozin/Velimirovic, which I don't have to do via my preferred move order (where my b8 knight hangs back and, in case of Bc4-Bb3, comes out on a6). 

So instead of 3...Nc6 I would prefer 3...d6 when White has, among other moves, 4.Bc4 which perhaps is a little stronger with Black's d-pawn committed to d6, e.g. 4...a6 5.a4 and it's a mess.  I don't suppose that Black has much to worry about, but on the other hand his game doesn't look that inspiring to me.

If White wants to play in this manner, he should play 2.Nf3 first, and then meet 2...d6 with 3.Bc4, so that Black cannot play ...d5 in one turn. This doesn't change the overall evaluation of the line, but at least forces Black to find a few good moves to secure equality. I can't remember the equaliser exactly, but I recall that Black plays ...Nf6/...e6/...Nc6/...Be7/...0-0/...d5 in some order, perhaps with ...a6 thrown in.

I have faced this 2.Bc4 line in some correspondence games.

May be used as a surprise weapon, but I use to play 2... e6 in order to play normal black setup (sometimes the game finally follows the Schevenigen Sicilian).

Do not be afraid of 2.Bc4, but the bishop at c4 square is a useful piece in many Open Sicilian Variations.

The reversed Sicilian has a different philosophy than the proper one, so I wouldn't necessarily try to compare them.

On 1. e4 c5 2. Bc4 e6 and you have a normal Sicilian where I think Black will quickly equalise in all possible variations. I think we had some discussion about this system some time ago (you can check that through the 'search' function)..
