blueguitar322, markovich,

Thank you for this.

I imagine White shouldn't hurry with ...dxc5, lest he ends up in a Q-less middlegame, something I'm not particularly fond of!
I guess either White should play along the line I suggested sub 2 in my original post.  Or Black could avoid this by playing 4 ...Bh5 instead of ...Nc6.  Then play could continue something like 5 c3 Nc6; 6 0-0 Nf6; 7 Re1..., and only after Nbd2 at some point would White be able to move his Queen out of harm's way without Black wrecking his K-side with ...Bxf3. 

Right?!

If I don't get 3...cxd4 (rarely happens), I almost always play 4 dxc5...it seems to me that after that pawn trade, White gets some of the same advantages as in the Open Sicilian (free development, slightly more central space) without the strategic drawbacks (2-to-1 center pawn minority, open c-file for Black to get counterplay).

And - for the minute or two I looked at it, which isn't much - the line you give (Bxf7+) looks strong to me. Black can get his pawn back, but the e6 square is terribly weak and the knight on g5 is in perfect place to hop right onto it.
