Pogonina vs Chess.com Move 22 ...
Alas, I have a serious work load outside chess for some weeks to come, so it will be near impossible to manage comments with some acceptable depth here. Hopefully I will be back later. It mainly has been an exercise of my humble analytical abilities and if it has brought some new thoughts to others as well, I'm glad.
Couldn't keep my hands off, but it is only a recommendation.
I have had a look at 22. ... b5. Some people have gone into depths looking at that pawn push. I can honestly say that I see no better options nor no worse - within the plausible move range. So why not go for it. It is certainly more fun to be active! The d-pawn is weak,yes, but that is as it is and it is defendable.
Will the b-pawn be weak? (After 23.axb5 axb5.) I think not. It is more probable that it will be traded for one of White's queen side pawns. In such a position, White will have a pawn that can be weak or strong, depending on how well the team plays
I would go for 22.b5
