Go is the oldest game – created 4000 years ago in China – and ranks as one of the greatest creations of humanity. It has much simpler rules than chess, but unlike chess, top computer programs are not capable of beating professional players.
1) It can be played on variable sizes of board so that students can pursue either long or short games.
2) Handicapping strong opponents is part of normal play.
Go is also a great game for schools because lost pieces are not critical.
