Lets start with some thoughts I have about the position after 4.d3:
Black is probably forced to take on e4: 4...fe4, cause after 4...Nf6 white may consider 5.ef5 and after 4...d6 the bishop on f8 is bad. After taking on e4 we have the starting position of the ruy lopez without the white d-pawn and the black f-pawn - which I think is very much in whites favour.
Perhaps we can try an analytical tree after 4.d3 - I propose
A - Variations without fe4 (Nf6, d6, etc)
B - Taking on e4 - blacks bishop goes to e7
C - Taking on e4 - blacks bishop goes to c5, white moves queen to c4 (via d3 or e2)
D - Taking on e4 - blacks bishop goes to c5, white plays early 0-0 (Macieja-Radjabov, 2007)
I am curious about the opinions of the chess community here...
Oh, I suppose I disagree. When I was playing this defense (before I discovered that 4.Nc3 just refutes it), versus 4.d3 I favored 4...fxe4 4.dxe4 Nf6 and soon ...Bc5, believing that Black was not much worse there. It's a game of chess, isn't it? Has something happened to cast a cloud on Black's game there? I'm not aware of it.
I certainly do not agree that the absence of White's d- and Black's f-pawn is particularly advantageous for White. The f-file will provide eventual counterplay, or if ...gxf becomes necessary, the g-file.
But it's moot because 4.Nc3! is so strong.
