7.Nc3 is basically the same as 7.Ba4, no? The point is 7...a6 8.Ba4 b5 9.Nxb5! axb5 10.Bxb5 etc. I only preferred the quiet 7.Ba4, because it is more amusing and stresses Black's problem: lack of moves. What Black wants to play is Qd6, but after 7.Ba4 Qd6 8.b3! or 7.Nc3 Qd6 8.Bf4 he is in trouble. Not so after, say, 7.Bg5 Qd6. 

For example: 7.Ba4 a6 8.Nc3 Rb8 9.Bg5 Qd6 10.f4 b5 11.Bb3 White threatens a2-a4 (and much else), e.g. 11...Nxe5 12.fxe5 Qb6 13.0-0 c5 14.dxc5 Qxc5+ 15.Kh1 +/-. 

In comparison, 4.Bb5 Qd6 5.d4 Bxf5 6.Ne5 Nf6, intending Nd7, seems less powerful. Note that after 7.b3, Black has 7...Qb4+, when it becomes clear that the bishop stands better on a4.

What I find stunning is that noone has questioned Stefan's 7.Ba4.
I see it is not a bad move, but can someone please explain to my why it deserves an exclamation mark?

In my eyes it retreats an unthreatened piece, and if the idea were to trade light-squared bishops with c3,Bc2 then why not Bd3 straight away?

Presumably in deciding on 7.Qh5, S Kasparov thought that he was threatening g4 after Qe2. given that this doesn't work, Qh5 has to be a mistake that just helps the black dark-squared bishop get to where it wants to go anyway. 

I was about to post that simple development (maybe just 7.Nc3) keeps a distinct edge for white when I saw Stefan's post. 7.Ba4! is indeed a nice idea.

In a recent game Black unleashed a queen sacrifice that won the brilliancy prize of the tournament and might refresh interest in the Colorado defense. It was reported in a German magazine that Kasparov accused his opponent of cheating during and after the game, but Schulze had analyzed this line until (position up to move 13 had been on the analysis board) shortly before the game which could be witnessed by other players. In fact, the queen sac had already been played twice in corr games 10 years before. Here is the game:

Siegbert Tarrasch once said: "Before the endgame, the Gods have placed the middlegame" 

As for the release, I think the scheduled date was July 1st. From my side, there is no reason to delay a release at that time -  I finished my manuscript and hope that you will be satisfied with the content!

Can't wait for that because i can't seem to get any where with 2..d6 at the moment. 
I was playing 2..d5 but the lines where white plays the early Bb5 and no d4 are just too painful. 
Is it still due in June??

Yes, I do.
