Random start go
Play go from a legal position that is randomly chosen.
I have played this, as implemented by the Maldoo machine of Yehouda Harpaz (see http://www.maldoo.com/). That makes setting up the initial position painless; one plays on by pressing touch-sensitive points. Suitable for children, for example.
I recently experimented with this as a method of handicap placement. It was fun, but I don't have any other conclusions to report. - Migeru
