I agree with the idea that focusing on life, rather than eyes, is the most intuitive. Then you can explain everything with a few simple statements.
1) a group is captured if there are not empty spaces adjavcent to it. 2) a group is alive if no sequence of legal moves can capture it. then you should simple examples of groups that are alive. As a side comment, you might mention that there are lots of unusual and tricky cases, where the "rules" clause gets complicated - Starting with false eyes, and sekis, bent four in the corner, and thousand year Ko. _______________________________________________ Computer-go mailing list Computer-go@dvandva.org http://dvandva.org/cgi-bin/mailman/listinfo/computer-go
