Brazilian, living in Salvador, Bahia.
43 years old.
I am married and have a six-year-old son.
I do not have an official chess rating.
Besides chess, my personal interests are computer technology, scuba diving, Formula 1, movies, philosophy and psychology.
My nickname, "Waitaka", is from a tribe of native Indian warriors from Brazil, aka Goitaca, extinct at the seventeenth century. They were reported as excellent warriors, never surrendering, and never losing a battle.
