I like Go.

Go is an ancient game with simple rules and very complex gameplay. Go is a two player game, it is played on a 19x19 board with black and white stones.

Learn the rules!

Compared to chess, go is 20-30 times more complex. (A computer has beaten a top chess player, but no computer program is near beating a competent go player.)

The go table in its potential complexity represents the infinite universe, the black and white stones represent the duality of nature, and the two players represent... err... whatever.

Go is an open game. It allows for a lot of personal expression in gameplay, and players' styles are quite visible.

What I like most about go is that the mental processes required to advance in go are applicable in other fields of life. An emotional imbalance is reflected in one's gameplay.

In chess, the gameplay moves 'sideways'. In go, the gameplay moves 'top-down'.

In chess, the 'hurt' comes in packages: you lose one of your pieces. In go, the 'hurt' is much more sneaky: when you play against a better player, you feel your territory slowly vanish, and you can't exactly pinpoint how it happened.

The sense of impending doom eats away at your heart. The fear is comparable to the real life fear of being bested by the unfairness of the world.

It's simple, really: if it's security you are after, you lose.

Go is a good tool to self-reflect - together!
