The positions are tough, especially the endings. I'm going to comment on this one only atm:
My evaluation is that White is playing against the clock in the sense that their chances for an advantage are about to evaporate. In these structures Black is always seeking for a liberating move, which in this case can be either ...c5 or ...e5. Black is ready to play ...c5 and they usually equalize with it easily. So, white should pick up moves to prevent that idea or to contain its consequences. We would like to play 1. Nd2 and then Ne4, but it's too slow. The move 1. b4 could be a interesting gambit to deflect the queen and use the g5 square to maneuver the knight around and attack as a well, but Black is too solid. I don't think it is worth it. Also, 1. Be4 is another nice idea, but fails to ...f5, followed by ...c5 I think. The best I can think of is 1. a4 to bother the pawns on the queenside, discouraging ...c5. A possible line could be:
- a4 e5! 2. Af5!? exd4 3. Rd4 and the rook is active and the pin, annoying. If now 3... c5 then it drops a pawn on b5. This approach is all about containing the consequences of the liberating moves.
This is a great content. Congrats.
