Lessons of a Position

In this position, it is Black to play. The e5 square seems locked down by White, which is important for black. The d5 pawn via en passant currently makes the e5 push not viable, yet this is a fundamental way for Black to equalize. Without a knight on c5 the e5 pawn push isn’t viable. White obviously plans to exchange off Black’s dark squared bishop with the queen and bishop battery. If Black plays an eventual …e5 then they’d have to be careful for tactics along the long light diagonal because the d5 pawn no longer obstructs the bishop. Black’s g7 bishop is quite valuable and active compared to White’s a1 rook, but rooks are objectively more powerful and maybe recognized later in the game.
