Hi,
my engine has often endings like that as well. Seems stalemates are not that
easy to spot for humans. Guess my engine is suffering the same problems your
engines shows. Also no QS here and an eval which consist of a very simple
material+square eval. Before I will add a QS, I need to get rid of a few bugs
first.
Roman
below are a few games which ended draw because the opp. missed the stalemate
trap.
