I have been wanting to write to you for some time, but never have time, so absorbed I am in playing chess. I play night and day and nothing in the whole world interests me more than finding the right move... Nothing transcendental going on here – strikes [in Buenos Aires, where chess competitions were organized that year for not professionals] a lot of strikes, the people are on the move. Painting interests me less and less.
