Modern vs old Archangel

i was exploring some lines and I was just curious why the immediate Bb7 in the Archangel has become extinct, most ppl playing Bc5 instead. The line does not look so bad to me, is there some kind of refutation or very good line for white?

Bd5

Why are there so many titled players called "Penguin"?

There isn't much else to do besides play chess in Antarctica

Forget your meds again caveman? Try not to derail this thread, show some respect for the NM.

 In the data base I looked at it was only called the Archangel when you make the move you suggest 6. ....Bb7, I don't know why because the Bb7 move is played later anyways and it ends up the same position with move order different. Maybe Nb7 is only psychological...gives black comfort of knowing they can castle after that.....but don't really know for sure....I like Penguins though, they are really tough animals....

As far as I know, Black doesn't play ...Bb7 early because White can play a setup with d3 instead of d4, playing against the bishop. I don't know if that's still a thing these days.

That's right, I think^. 

It does stop the move 7.Ng5 (which is no real threat at all - black equalizes after finding a few rather simple moves after 6...Bb7).

But a more likely reason is simply because ...Bb7 is more committal - tons of lines in the Ruy Lopez involve putting the bishop on g4, instead of on b7, which isn't that great for the bishop, if white wants to play against it. ...Bc5, on the other hand, is just a decent developing move that doesn't really "commit" anything. 

CE's response (#11) is correct. I'm no expert on the Archangel, but I recall reading an in-depth article about it several years ago and was curious myself about the absence of ...Bb7. But the lines that I saw as I read through it gradually satisfied my curiosity, by showing that the bishop often was usefully developed to g4.
