I think the problem with live and death is that if it comes to a group 
that will die the pro will resign; if he can save the group the bot may 
not even got it that there might have been a live and death issue.

So, why can't you train the DNN on pure live and death problems, just 
like human players do it - from time to time. There are many collections 
(some even with solutions).
