I find this variation interesting, but it appears winning for white. Could you tell me your opinions?

6. Bb5+ main line ideas for white 
 
 
Looks like with best play white will gain a pawn but be forced to give up the bishop pair, at least in the Bb5+ lines. I think Qe2+ lines probably offer more, but I need more analysis there.

There is a very interesting idea that I need more analysis on, it is 6. Qe2+

My computer prefers it by a lot, though it seems much harder to calculate. Could I have some help analyzing this?

Interesting...what I always played on d4 was Ne4, keeping the pawn, but black has Bc5. I still think white is better in that line though, due to the bishop pair and potentially weak d4 pawn. However, that pawn also has a somewhat cramping effect on white's position so it all depends on the situation.

There is another interesting idea: Combining the 2

 
What do you guys think of this variation, of all of this? It can be found here:

Regarding Qe2+, that seems logical, and I like it. After Be7 then Ne4 with the threat of Nd6+, and the same on Ne7. Thus, black must play Be6 there and white has two options:

A). Ne4

Ne4 is met by simply Bxc5 and all that has changed from 6.Ne4 Bxc5 is that white's queen is misplaced on e2.

B). Qb5+

White goes pawn-grabbing. I think black gets some initiative after Bd7, perhaps enough (but definetly unclear), so Qd7 is probably best.

I would really want to see computer analysis of this opening. I don't have access to chessbase currently (away on vacation), but when I come back I will run this through it.

Thank you for the input! Could you clarify what line you are refering to?

I think the variation is unsound. Your line looks quite convincing (by that I mean the Bb5+ followed by Qe2) and I just don't see any compensation for black. Black's better of with either the Rubenstein (dxe4), the Winawer (Bb4), or the Classical (Nf6).

Quick question on this:

How can black play Bc5 if white's knight is on d4?

 
for (B) Qb5+ looks interesting!

Ok, on this line:

Thank you! I just wanted to analyze it because I have faced it otb twice (once in a tournement game yesterday) and so sometimes people play it because they don't see the flaw and I thought it would be fun analyzing it, maybe preparing a bit just in case.

And I agree, those are all better options.

Ah, this is why I do not recommend doing serious analysis blindfolded :D

You have got the right idea but Qe2 is well placed, and 6.Ne4 Bxc5?? 7.Nxc5 wins a piece. Qe2 defends the Bb5 from any Qa5+ lines.

Robert, on your quote sorry, I typo'd. I meant e4, not d4.

What about forks? Bxc5 Nxc5 Qa5+?

Parimarjan Negri book dismisses 3..c5? due to the line 4.exd5 exd5 5.dxc5 d4 6.Bb5+ Nc6 7.Qe2+ Be6 8.Ne4 is already close to winning.

I said that the queen on e2 WAS well placed and Bxc5 Nxc5 Qa5+ is quite a simple tactic. However, after Bxc5 just Qb5+ as shown in one of the above posts.

Then Bd2 holds everything.
