Hi Wolfgang,
indeed ... in this 16000 nodes area, The King easy should be better on par with ~2150 elo opponents, according to my own forecast. The 1865 SuFo is way below.

I think we would need more games using hereafter levels (and, if possible for diversity, different program authors as opponents):

1) Without any tests so far:
@250 nodes, should be ~1170 average opponents
@2000 nodes, should be ~1750 average opponents

2) Needing more data:
@8000 nodes, should be ~2040 average opponents
@16000 nodes, should be ~2150 average opponents

I enjoy playing low level computers, so I will play and provide data for the @250 nodes.

Anyone enjoying completing other levels data is very welcome, thanks!
Kind regards
Eric
