As a Go player, my favourite anecdote about Olivia de Havilland is that her father became so addicted to the game in Japan that his wife divorced him. He married a Japanese woman and went on to write the first Go book written in English.
> Lilian and Walter met in Japan in 1913 and married the following year; the marriage was not a happy one due in part to Walter's infidelities.
From https://en.wikipedia.org/wiki/Olivia_de_Havilland#Early_life.
And apparently in his wife's own words
> spoke like God, but behaved like the Devil
from https://books.google.com/books?id=nmjetV92THsC&pg=PP1#v=onep...
It doesn't seem like Go was the reason for the divorce.
