Hi Sylvain, FWIW, I have also observed this behavior recently in a rated game against my bot ggexp and it seems actually possible to cheat bots on KGS, even when kgs-genmove_cleanup is implemented (which is the case for GNU Go and clones). I don't have the logs anymore, but I clearly recall seeing a warning in the kgsgtp output, about the engine "still claiming stones at xx" (rightfully), right after a second (and, to me, unusual) "dead stones submitted" message. I informed an admin and he told me, they'll look into the issue.
Running the bot with the --capture-all-dead option, combined with chinese-type rules (which can be enforced for rated games) would solve the "problem" (doesn't give a chance for the opponent to claim anything more than he should), but that precisely, wouldn't be very nice for those who play fair (the vast majority) -- nando _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
