Default Sicilian Classical

The Larsen line of the Classical 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4.Nd4 Nf6 5. Nc3 d6 6. Bg5 Bd7 seems fail after 7. Qd2 Rc8 8. O-O-O Nd4 9. Qd4 Qa5 and it seems that just about anything gives white an advantage. For example 10. Be3 or 10. h4 But I really need an answer to 10. Bd2 If someone can provide advice and help with 10. Bd2 would be appreciated!

Now that I know what I am looking at, the basic idea here for black is to play e6, bring the bishop to e7 and castle.

Nah its not. e6 Bxf6 gxf6 and the black king dies on the kingside. It stays in the center where it is vulnerable to Nd5 ideas.

Bd2 doesn't seem right. All of white's ideas in this opening are telling me to take on f6 in this position, bring the rooks to the center and prepare to either open it up with a pawn sacrifice or a piece sacrifice on d5.

Just a heads up, the articles that I have say Be2 is best after Bd7 according to theory.

10.Bd2 a6 White cannot play 11.Nd5 yet because of 11...Qxa2
If white plays 11. Kb1 you need to respond with Qc5. Endgame is somewhat equal, albeit a bit more pleasant for white (but plenty of life in the position!).
Then you might have to play e6 and Be7, with another bishop going to c6 (after rook retreats from c5).
If white plays 11.f3 you have time for 11...g6. Then after 12.Kb1 Bg7 13.Nd5 you can play 13...Qa4 with excellent counter play.

Does this defence provide equality and perhaps even winning chances? 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.Bg5 e6 7.Qd2 Be7 8.0-0-0 Nxd4 9.Qxd4 a6. One might call this the Kramnik Variation.

10.f4 and white can activate the other bishop with 10.Bc4 when Qc7 11.f4 (perhaps 11.Bb3 idea b5 12.Rhe1) b5 12.Bb3 Qc5 looks like an equalizer. I could not find much against 11...h6 either.

10...b5 11.Bxf6
11.e5 dxe5 is not convincing.
11.Be2 Bb7 12.Bf3 Rc8 13.Bxf6 gxf5 14.f5 Qa5!?
The text move is Gary Kasparov's choice. Again Black has to play a kind of Botvinnik setup (7...h6 8.Bxf6 gxf6) and again it seems to be an improved version.

11...gxf6 12.Bd3 Qc7 but perhaps Black can do without this move and play 12...Bb7 instead. Pawn e6 remains sensitive.

13.Qe3 Qc5 14.Qg3
14.Qh3 b4 15.Ne2 Bb7 idea 16...0-0-0.

14...b4 15.Ne2 Kf8 16.Kb1 a5 17.Rc1 a4 where black has developed counterplay. His pair of bishops are an important trump on long term.

This approach is more direct than Kramnik's choice 17...h5 in a game from the mid 90s.

I haven't played this line, but it's quite a mainstream and leads to a typical Rauzer position that I often get from similar lines (two bishops vs double f pawn). I view it as close to even (very small plus to white) with mutual chances.
Useful rule of thumb (by no means absolute!) - if black manages to swap queens they have slightly better chances in the endgame.

This line is not acceptable for Black because of the incisive 8.f4! Nd4 9.Qd4 Qa5 10.e5 de5 11.fe5 e6 12.0-0-0 and Black's unsafe king, coupled with White's initiative, provide White with a clear advantage.

Not quite. Black often withstand the attack (quite successfully).
The attack can be avoided all together by playing 8...h6 9.Bxf6 gxf6 converting to typical Rauzer structure of 9.Bh4 g5 which is a different sharp line.
