I was a professional chess player in Romania, but only a small-time master. When I came to France, I continued playing chess for many years: I played tournaments in numerous countries with mixed results. I wrote and published a book - La Défense Alekhine and translated two others from Russian. I taught chess in schools; I earned more money through chess than through literature.
