This is the biorhythm chart for the World Human Chess Champion Magnus Carlsen for November 26, 2018, the day of game number twelve, the last game of the so called “classical” part of the match for his crown:
Because Magnus was having a physical critical day, transferring from a high phase to a low phase, the worse possible day of each month physically (invariably much worse than a physical critical day going from low to high), it was a bad day. When one considers the fact that Magnus was coming off of his floor intellectually it made for a terrible day.
The challenger, Fabiano Caruana:
It is usually a good day when one is in the high phase in all three categories, as was Fabi.
Looking ahead to Wednesday, November 28, 2018 when the hurry up and get it over games are played we find this chart for the World Human Champ:
Physically and intellectually low while high emotionally is not a good chart for anyone at any time.
Now let us look at the chart of the challenger:
Fabiano will be in a triple high phase, which is usually makes for a very good day.
Biorhythmically speaking it will be a HUGE advantage for the challenger. Because of the biorhythm advantage, Fabiano Caruana will become the new World Human Chess Champion. You heard it here first.

In light of this shocking draw offer from Magnus in a superior position with more time, I reconsider my evaluation of him being the favorite in rapids. Tiebreaks require tremendous nerves and he seems to be losing his.
