Looks like you should do as /u/ChucklingBoy suggested and go through the rules once more.. If you understand the rules, it should be very hard to lose on 9x9 with 5-stone handicap, unless you are doing it on purpose. http://senseis.xmp.net/?TheInteractiveWayToGo By the way it looks like GnuGo's slider only changes the speed which it plays, so I'd suggest trying out Pachi for Android.. For example easiest setting, 9x9 and 4-stone handi.. (he will resign with higher handicap) https://play.google.com/store/apps/details?id=net.lrstudios.android.pachi&hl=en
