magnus is almost definitely on the spectrum and has rain man level of recall. he remembers move for move games he played in like 2008. that is not how a normal brain works. you should only need to hear him speak for like a minute to realize he has the tism, or possibly even asperger's. so no, he is not winning based on pure skill. the only way to get to that upper elite level of chess ability is to be like that and there is quite literally zero exception to this.
