D53 Queen's Gambit Declined: 4.Bg5 Be7: Early deviations (1.d4 d5 2.c4 Nf6 3.Nf3 e6 4.Bg5 Be7 5.Nc3 h6 6.Bh4)

Again one of those rare openings you do not see all that much. As the games that are shown in the notation suggests, people who have played similar way in the opening are not that high rated. I would like to get a database in which only over 2400 rated players are but I guess as there might not be one easily accessible anywhere that if I would like to have one, I would need to make one myself but that seems like a lot of work. Might be easier just to play the openings in the way that higher rated players play them in order to get some examples of those in the games that I post here. I guess I should examine the games of someone who seems to know their Ruy Lopez or any other opening I would like to learn. Even though I heard this recommendation in a lot of sources, I have never really followed through with that. I just like to test moves on my own and see what seems to work.
