This was a great conversion by Magnus. Re1 took a while to understand. I needed the engine to help me understand why it was played but it makes great sense. Trying to exploit a slight weakness on f7! Damn !
Wondering why Rapport didn't go B x f5 at 54:47 taking the pawn and putting pressure on the pawn on h7 which could be taken by the rook next turn which kicks out Carlsen's queen?
