Magnus' idea was to sack the a7 pawn, which at least allows him to regain control of the open file with Rd8. This would also come with tempo as white king has back-rank mate issues. Then after white reponds with a move like g3, black has some counterplay with Rd2 and a fork on f2 and b2. But Artemiev saw all of this, and just played g3 first, with the followup idea of meeting Rd8 with Qc3 where both of magnus' pieces would be hanging and he loses. At that point, magnus realised his mistake and tried to bail out with Qf3, seeking a perpetual check.
Not really strategic mastery. Slightly worse in the midgame, losing in the endgame, and then wins off of forcing blunders against a low time opponent. Classic Magnus with his rock solid endgame.
@6:28 if he would've put Queen F5 he would attack the Rook and the 1 file, Rook takes pawn, Queen B1 Check, white is forced to block with Queen, Black Queen takes with Checkmate
Strategic mastery? Not in this game, and you know it . Carlsen's own commentary gives the lie to your wild claim. I hope it was worth trying to fool us for the pittance RU-vid will pay for such small viewing figures.
clickbait There's no strategic mastery. Equal play, then Magnus blundered a bit and lost advantage, and then opponent got short on time and made mistakes.
