Those who think they can raise their rating by only playing patzers, really do not understand the math. Players get tired and can make a mistake against anybody and lose a game even against a "patzer". In the long run, you gain nothing playing against "patzers" This is the math.
On a practical basis it is really a stupid thing to do as you hurt your chess playing abilities if you only play "patzers" and what do you gain?
Your rating can be inflated, but only to a point. And yes, every game puts all of those gains at risk, but to say that it's not possible at all to inflate your rating by doing this is just plain incorrect.
I am saying it is not possible in the long run. In the short run you can win one game and raise your rating a small amount.
It is a bad idea to try and raise your rating by playing players far lower than you. There are several r easons this is a bad idea.
Carlsen does not play players rated 500 points below him.
Yeah, that Carlsen dude is such a cheater. He only plays people rated lower than himself.
Anyone who tries to raise their ratings by playing only opponents rated lower than themselves will not gain much either in ratings or in skill.
Carlsen is #1, everyone is lower rated than him
facepalm
