Hi GM Avetik,
Could you take a closer look at this line? In his recent chess24 series on the London System, GM Adrien Demuth gives 7.Qd2! as the reason why 6. ..Bg4 isn't great (he thinks 6. ..0-0 7.Ne5 c5!? is Black's best try). For example 7. ..Bxf3 (to justify ..Bg4) 8.gxf3 c6 (8. ..0-0 9. 0-0-0 c6 10. e4 e6 11. Bg5 +/-) 9. 0-0-0 Nbd7 10. Kb1 e6 11. e4 and it's not clear how to continue with Black.
I posed exactly this question about a month ago, see the following link for answers:
I was really curious about what Demuth was offering in his course but could not afford to purchase it. Thanks for showing his recommendation for Black and I hope that Avetik gets around to sharing his thoughts on it sometime in an Advance Section update.
I wasn't aware that you had raised the same concern. Let's hope the ChessMood repertoire will be amended (or changed) in response!
Here is GM Demuth's recommendation for Black:
6... O-O "instead of ..Bg4 I think it's stronger for Black to go short castle" 7. Ne5 c5!? "I think the strongest plan is to play ..c5 [instead of ..c6], I think this is definitely one of the ways to go for Black [in this line]" 8. Qd2 Qa5 9. f3 "we more or less need to stop ..Ne4 at some point" Nc6 "it's not so clear how we should proceed because Black is getting some activity, and after" Bb5!? Nxe5 11. dxe5 Ne8 12. Qxd5 "we can take a central pawn but Black has a lot of activity to compensate" Be6 13. Qe4 Nc7 "we have to move the bishop, ..Rd8 is coming, so this position should be probably about equal, White should play Qa4 or Be2, but this is quite difficult to find for Black, that he needs to take on e5, sacrificing a pawn"
I just had a look. Apparently, the key setup for Black is ..Nc6, ..e6, ..Ne7. For example: 8...0-0 9.0-0-0 e6 10.e4 Nc6 11.Rg1 Ne7 12.Bg5 Rc8 13.Kb1 c5.
As this is a critical line for the variation, I think it deserves GM explanation/assessment. :-)

The Nc6 line in the file that Avetik posted looks ok, but admittedly I prefer Demuth's solution as it seems easier to play and is more thematic for how I treat these 'Barry' type positions in general, that is go 0-0, c5, Nc6 then have a look around to see what White's up to and react accordingly. A typical example being:
