I do not clearly understand the suggestion by Lichess computer analysis. What is the problem with the move 5.Bg5 if there is one ? Lichess computer analysis suggests me that 5.Bb5 was better, but my idea behind Bg5 was to defend e4 pawn and if you go for Bb5 you sacrifice the pawn and I do not see what compensation I have for it (I played for white). Thanks in advance.
