As a life long player of the Ruy as White I have always found Bird's quite tricky to play against.
My concern with the Schliemann's is 4.Bxc6 which dull's the position somewhat.
By the way I think 4.d3 v the Schliemann is quite underrated. (Its recommended in Greet's recent work 'Play the Ruy Lopez'😉
Lots of things are written in books, but they're not all right. I'm a bit wary of the objectivity of repertoire books where white always seems to gain an advantage, or if it's a black opening, black always seems to equalise at least!
As for 4.Bxc6 against the Schliemann, I actually quite enjoy playing against it (more so than against the normal Exchange Lopez). 4.Bxc6 followed by Nc3 and Qe2 was presented in a NiC Yearbook a few years back as a way for white to gain a positional advantage against the Schliemann without any risk. Not surprisingly it became quite popular.
But do not believe it; black is fine! I've had considerable success with the line 4.Bxc6 dxc6 5.Nc3 Nf6 6.Qe2 Bc5!? (not that's anything too much wrong with the more usual 6...Bd6 or 6...fxe4) 7.exf5 Qe7.
I don't normally play the Lopez as white, but if I did, I would almost certainly play 4.Nc3 against the Schliemann; it is by far the most critical variation.
