Fair enough. I know my grasp on positional play is weak, so it makes sense I'd underestimate that advantage. [Or I'm secretly as good as the supercomputers. Either one.] This is why I hate how engine evaluations (while useful and important) have replaced analysis. It robs people of the chance to see *why* positions are good or bad for each side and replaces it with a single number. Take the position after 22. Rxc1. Black is up the exchange (rook for knight) and a pawn, which in traditional valuations is 3 points of material, or roughly equivalent to one full piece. What does white have to make up for that? First and foremost, an outposted knight on d6. That is probably the strongest knight you will ever see in a high-level game like this. Centralized on the sixth rank is probably the best spot a knight can ever have. It has maximum influence over the center of the board and over the back ranks where black's king is. And there's no good way for black to deal with that knight. It can never be attacked by any of black's pawns, and neither can the e5 pawn protecting it ever be attacked by one of white's pawns. The knight can never be traded off evenly, because black's only remaining minor piece is a light-square bishop and d6 is a dark square So black just has to awkwardly play around it forever or give up and trade it for a rook, giving back the exchange. The second big advantage white has is black's pawn structure. The pawn on e6 is isolated and could easily become a target someday. The black pawns on the queenside are vulnerable to what's called a "minority attack" where a smaller number of pawns is about to trade into them and bust them up, prevent them from comfortably advancing. The third big advantage white has is that none of black's pieces are well-placed, nor do they have obviously good homes. Well, the rook on f8 is fine. But where's the other rook supposed to go? It can't do anything on the d-file because the knight can squat in its way forever. The other rook can't double-up on the f-file because white has solid control over every single square on the f-file besides f1 (look at how the knight and pawn combo are dominating f7-f5). Meanwhile, the black bishop is even worse. It's the light-square bishop, but white's pawns are stick on light squares all over the place, roadblocking the bishop's influence. Compare that to white's bishop, which can exert pressure where it is now, or it could go to h3 and pressure down the diagonal that contains both the isolated black pawn and the black queen. Or it can go to e4 and put pressure on h7. Tons of options for white, while black has few obvious ways to improve his position. In a casual game against another human being, I would gladly play the white side all day long. Super-GMs are better at defending against dynamics than I am, so these guys would probably do better with black, but it's definitely not as good for black as the eval would imply. I hope all that made sense. I guess I could shorten it by saying: Super-strong knight on d6, black has no good way to double rooks, good bishop vs. bad bishop
