Why is it that when we use lower rated account we perform worse

I've wondered why The Goat and Best GM Magnus Carlsen always wins some seemingly lost games where his opponents just blunder out of nowhere without reason...some have called it the Magnus effect but what's behind it

I've watched The Best GM streamer Master Of Premove and second Goat GM Hikaru's streams....He always say "I should be winning now"....then later "I'm winning but I don't know how"....Sometimes he uses the words "it's now Chichy" but there is no instant win

One should be deluded with being Higher rated Than your opponents to shift the unseen energy in your favour and assert dominance whilst playing a game with higher and lower rated opponents....This will make you play better

It shows that you have to motivate yourself in winning positions to win...That will be your mentality on a good day you play chess your best
