I'll concede for a 5x5 board, but I think my point is valid for "sufficiently large" boards, probably 7x7. Almost any strategy other than playing out all legal moves involves a lot of hand waving that is unlikely to be accepted as a proof. There are just too many cases where a pitch inside a captured space has global effects. _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
