The game of go has been my favorite game to play since I was children. It is a board game for two players that originated in China more than 2,500 years ago. The game is rich in strategy despite its relatively simple rules. The game looks very simple to play; however it is very hard to master and I got 3 dan( rank for advanced player, the highest is 7dan; for professionals, the highest is 7dan). Upon now, the computer still cannot beat human's head which shows how complex the game is.
