Some questions on Alapin Variation (B22: Sicilian: 2 c3)

Note:The commentaries without text are made by Fritz 13 with a little time

As somebody not good at Sicilian (what a shame), I faced the 2.c3 line playing black:

1. e4 c5 2. c3 Nc6 3. d4 cxd4 4. cxd4 d5 5. exd5 Qxd5 6. Nf3 Bg4 7. Nc3 Bxf3
8. Nxd5 Bxd1 9. Nc7+ (9. Kxd1 O-O-O {Where the actual game stopped with the accidental (9.Kxd1?!})
9... Kd7 10. Nxa8 Bh5 I was told that the position at 9.Nc7+ is winning for white (the original words were like "a line that's lost on 6.")

And the engine did gave something like 0.60 (+/-) after 14.Bxa7 or 14. Bb5+ —— which is probably based on the (meant-to-be) lost a7 pawn or initiatives black will give up when trying to capture the Knight on a8. But does it really mean black is lost without chance to equalize?

Is this 7. ... Bxf3 line something commonly not suggested?

I even went on wikipedia for the name "Alapin", so I'd be grateful for any kindly pointed out mistakes.

2...Nc6 is not a common line against the Alapin. You have three main choices: 2...Nf6, 2...d5 and 2...e6. 2...e6 may be best but it can transpose to the Advance French Defense. Hence you should probably go for 2...Nf6.

2. ...Nf6 line is better.I'm not saying e6 has something wrong,it's good enough,especially when you know advanced french well. But I suggest Nf6 because it's more "sicilian". Black can have a more flexible center pawn structure, which promise a quicker and sharper center counter attack.

And another reason I suggest Nf6 is that it's also a much reliable reply to the Smith–Morra Gambit

i playing e6 usual this set up, but like say above get taken to French defence advance game, which i am not liking... alapin is nasty variation of sicilian, very difficult game,

You have transposed into a known line that arises in the mainline 2...d5 variation. It's rarely played, because Black has safer looking paths to equality, but it seems playable
