Go is an ancient board game originating from China, believed to be over 2,500 years old. It is played on a grid of intersecting lines, typically 19x19, although smaller sizes such as 13x13 or 9x9 are also common for beginners. The game involves two players, one playing with black stones and the other with white stones. The objective of Go is to control more territory on the board than your opponent.
