They call it the New Archangel in the Everyman book from 2000 and in every article I've seen on it.  I'm sticking with that name.  I don't see any reason to name it after Tkachiev.

It's great that Shirov is doing a new DVD on it.  I remember on one of his Spanish DVDs he mentioned that he and a group of top GMs had analysed one of the main positions out until something like move 30 but that he wasn't allowed to reveal any of it!  Maybe he can talk about this now on the new DVD.  I think he devoted a lot of time to it on his Spanish 3 DVD already.

The general consensus is that c2 is a better square for the bishop than b3. This particular case might be an exception indeed, depending on the strength onf 7...d5. Shirov has lost twice with it, but Onischuk has drawn a couple of times against first class opponents.
Is there a route to an advantage for White after 7...d5 ? If not Daniel has a strong case.

I have usually seen 5...Bc5 6. c3 b5 7. Bc2 given as better for White than 7. Bb3 (= 5...b5 6. Bb3 Bc5 7. c3), but never, as far as I know, the other way around.

Yes, the nomenclatur in wikipedia tells:
4...Nf6 5.0-0 b5 6.Bb3 Bc5 (Modern Archangel Defence)
4...Nf6 5.0-0 Bc5 (Møller Defence)

Strange, I thought this line was known for the longest time as The Moller Variation of the Ruy.

Tops

The variation against the Ruy Lopez presented in meticulous detail by Alexei Shirov (3...a6 4.Ba4 Nf6 5.0-0 b5 6.Bb3 Bc5) has so far had no recognised name and Shirov himself has named it after Vladislav Tkachiev, the 2007 European champion, the Tkachiev Ruy Lopez. In fact the grandmaster from Kazakhstan has played a few important games with this system, but it would have been just as justified to name the variation after our author himself, because since 1996 Shirov has not only played numerous games with it, but recently he has turned it into his main weapon against 1.e4 - with splendid success and a lot of imitators. The super grandmaster now shares all this collected knowledge with his viewers. Apart from the Exchange Variation (to which Shirov also devotes a model game) White has hardly any serious deviation after 3.Bb5, making of the Tkachiev Variation a good weapon against the Ruy Lopez.
