_every_ loss will trigger learning at a minumum.  popping out of book in a bad
position (bad score for crafty) will do the same.  And finally any loss should
also trigger some position learning (position.lrn should grow) due to bad
scores.  If they are empty something is broken in the setup as I am getting
learning from nearly every game Crafty plays on ICC...
