Hi how did you know about this line. On chess.com I found 4... Bf5 and 4... Bg4.

It came up in a lichess game and was misclassified as D00. This is a pretty common line. One example:

[Event "DM Carlsen-Dubov"]
[Site "chess24.com INT"]
[Date "2021.04.22"]
[Round "3"]
[White "Dubov, Daniil"]
[Black "Carlsen, Magnus"]
[Result "0-1"]
[ECO "D11"]
[WhiteElo "2710"]
[BlackElo "2847"]
