Sacrifice in the french TWO!!! ignore the first one

Okay I got carried away with the first post but I think this is a legit gambit where piece sacrifices are still possible.

are these any better?

wtf? anyone know what happened?

In the second one, black can simply 12...g6, 13.QxB O-O. He's going to lose the bishop anyways, and I see no clear advantage white can demonstrate.

After 14.Qxe6, white is winning clearly.

But in the line given, after 12...Ke7 13.Bxd7 Bxc3, black maintains his material edge, and white won't have enough pieces left to harass black's king.  In fact, its march toward the center will probably just be of benefit if black can force a swap of queens.

I see.. I guess I didn't look enough, thanks, I agree with you in the line given, the OP wrote "White is much better" is totally false. But the position with white to move does threaten Nxd5+ and Qxg7+, but after 15.. Kf7 white is obviously not better, Qf4+ can be answered by Qf6 and black might even be better.

So @the OP, can you tell me how is white better in the last line you gave? I understood the first only. (Well, black played the opening rather poorly, that was not a standard French line if anything)

 White can push f4-f5

Well, this variation is flawed in several ways. 6... a6 is a perfectly viable alternative to 6... Nc6, and after 7. Bxd7+ Bxd7 8. Be3 Nc6 9. dxc5 Qc7, black appears to be totally fine here.

Anyways, going back to the line, 8... Ncxe5? is a mistake, and 9. Bf4? is not the way to punish it. Instead, better is  9. Qh5 Qf6 10. Re1  Bd6 11. Bg5 Qg6 12. Qxg6 hxg6 13. Bf4 and white is bound to get a pawn back with the better postion, for example, 13... Nf3+ 14. Nxf3 Bxf4 15. Nxd5 +/- Also possible 9. Re1 Bd6 10. f4 Nc6 11. Nxe6 fxe6 12. Rxe6+ Be7 13. Nxd5 with some interesting pressure for white.

After 9. Bf4? black can avoid all those tactics with 9... Ng6 and he has a solid extra pawn.

After 9... Bd6? you again miss the correct move. 10. Bxe5? Bxe5 11. Nxe6 fxe6 12. Qh5+ Kf8 (13... Ke7 also works) 13. Bxd7 Bxc3 (instead of 13... Bxd7?) 14. Bxc8 Rxc8 15. bxc3 Rxc3 and black does have an extra pawn. The better way to punish 9... Bd6? is 10. Nf5! exf5 11. Qxd5 Qe7 12. Rad1 Bb8 13. Bxe5 Bxe5 14. Rfe1 0-0 15. Bxd7 Bxd7 16. Rxe5 and white is in a position of strength.

Don't play the 5. Nf3 line. It's better to go to the normal Tarrasch lines after 5. Bd3 or 5.f4

Does pretty much nothing...You don't have enough pieces to start any attack, g6 can be played and black can simply try to trade queens. And also 13...Bxh7+ and I would even go as far as to say white is worse because he doesn't have enough compensation for the pawn.

I don't understand why none of you guys are going 13... Bxc3... black is just better. Look at my lines above.

In the above line: instead of 12... Bxd7, black has 12... Kxd7, and there's no more fork, so he keeps a piece.

Good analysis duskrevival - Just one small inaccuracy in the very last move

I still do not think that this opening is sound. White has better ways of being aggressive in the French.

I fully agree - If you play white and you come out of the opening with a pawn down in an equal position you´d better do some extra work on your repertoire ...
