I enjoy the ancient Chinese strategy game Go, although I am hardly an expert. The open-source GnuGO AI built into the computer version of the game I play overpowers me much of the time.

After many years of having gone without, I recently received a Go board and set of stones as a gift. Immediately I noticed the most important difference between playing on the computer and off it: touching the board and the stones.

I had forgotten what a tactile game Go is. The black and white often have a different texture from one another, depending on the type and quality of stones one uses. The feel and weight of them between the fingers somehow aids the pondering that comes with their placement.

Once the player chooses a move, placing the stone on a real board offers a far more tactile challenge than clicking an on-screen goban. The stones move, so disrupting the board is an easy feat that must be carefully avoided. Traditionally, Go players would hold a stone between the index and middle finger and strike their move, so as to create a sharp click against the wooden board.

Go is a cerebral, minimalist game that exudes purity and austerity. Computer versions of Go adapt these values unflappably. Although purists favor silence in selecting and holding a stone, for me Go is a game of rummaging for a stone in a smooth wooden bowl and stroking it in thought before placing it to mark territory. These features are not unique to Go, but they are distinctive. In Chess, the pieces rest on the board, or off, never to be touched save to punctuate decision. Although both games are cerebral, Go is far more sensual.

Go reminds us that the physical world -- games included -- have texture. They offer tactile sensations that people find interesting on their own.
