Why is Carlsen being praised for his tie-break play, when Caruana made several game-losing moves? I followed the three games live on chess24.es (for live commentary from GMs) and chess.com (for actual real time computer analysis).

As per my understanding:


Game 13 was mostly balanced until 19... Nb5? (GMs were expecting Nb7 if anything), and then after 34... Rc3? it was definitely over.
Game 14, Caruana was in a better position until 21. c5? which brought it back to balance, followed "shortly" after by 26. c7? which was definitely a losing move (live commentators went nuts here).
Game 15, there were no "obvious" errors (not that the GMs noticed on-air, at least), Caruana was even leading, but in the last half of the game the computer was marking several of Caruana's moves in red.


As far as I can tell, Carlsen didn't make any winning!! or distinctly good moves. Yes, he played great and made very few errors, but my feeling is that Caruana lost the game, more than Carlsen won it.

So, why is everybody praising Carlsen for his play? What moves or strategies did he apply in the tie-breakers that show how good he is?
Carlsen crushed it, made almost no mistakes whatsoever in rapid. It is as if he was playing at classical time controls.

Chess is about not making mistakes. If your opponent doesn't make mistakes then you're only going to get a draw even if you play like an engine.

He did play good moves as well. Example on move 37 the position is a draw but he gave himself winning chances with 37. Rc7!. Caruana now blunders with Kxe4 instead of playing Ra2+. Now Carlsen plays the accurate Re7+! instead of Rxg7? and obtains a winning position.
