A game that very simple and easy to learn
But very hard to be master.
Weiqi was developed in China more than 2500 yrs. ago
Spread to Korea(Baduk) and Japan(Go), in about the 5th and 7th centuries CE respectively, boards with a 19×19 grid had become standard.
As of mid-2008 there were well over 40 million Go players worldwide, the overwhelming majority living in East Asia.As of May 2012, the International Go Federation has a total of 74 member countries and four Association Members covering multiple countries.
Einstein with Go Professional
In 1996, NASA astronaut Daniel Barry and Japanese astronaut Koichi Wakata became the first people to play Go in space
Objective
Go is an adversarial game with the objective of surrounding more territory than one's opponent. As the game progresses, the board gets divided up into areas of territory, as outlined by groups of stones. These areas are then contested in local battles, which are often complicated, and may result in the expansion, reduction, or wholesale capture and loss of the contested area.
