The old Chinese habit of starting a game with two white and two black stones on the four corner star-points may be a remnant of this. The Sikkimese board was very large and made of cloth . The stones were of the type once usual in China - a sort of flat cone. No records of games played on a 17x17 board exist. Although not illustrated by this game, the method of counting at the end was said to be the same as in modern China.
Dame have value and so are played out.
There was no two-point group tax as there was in old China. Sekis were known. White played first but it was the stronger player who took White. His advantage was offset by komi, but they did not say by how much - probably there was a variable komi in lieu of a handicap system. Cheng's view is that in the area now encompassed by Tibet, Nepal, Sikkim and Bhutan go first appeared around 700 AD .
