Hey Peter,

To my best knowledge there is no universal standard for that but KGS's
convention is probably the most popular for us.


   - *Japanese* - mostly used (territory and prisoners count)
   - *Chinese* - easiest for beginners, bots (programs running on KGS)
   mostly use chinese rules; area covered by stones plus surrounded territory
   counts, you may capture closed in stones without changing the result!
   - *New Zealand* - similar to Chinese, but two or more stones may play
   self capture.
   - *AGA* - American Go Accociation, uses japanese and chinese counting
   (don't mind - the server does the counting for you).

> 			"GOE" (the Ing rules of Goe)
> 			"Japanese" (the Nihon-Kiin rule set)
> 			"NZ" (New Zealand rules)
