"I have come to the personal conclusion that while all artists are not chess players, all chess players are artists." This quote from Marcel Duchamp, the French-born American artist and chess player, seems to be the most relevant definition for street chess. When it comes to outdoor chess spot in New York City, Union Square is one of the most popular location for playing. Street chess is normally played with few minutes time control (fast chess), but it is also possible to take lessons from chess masters there. Chess was born in the seventh century in India, and is it certainly the most humble and sophisticated board game at the same time. Chess playing is an art, and requires philosophy.
