This version of Nightmare was running on an old Intel Atom processor, I guess it was a little bit out-searched.JVMerlino wrote: On a lighter note, Myrddin's win over Nightmare was rather strange. Here's the position right after Myrddin left book.

Most engines give White at least a +1.5 advantage here. Nightmare must have huge bonuses for passers because in this position, instead of developing the kingside bishop like every other engine I tested, it uses it next THREE moves to push the h-pawn all the way to h6, giving Myrddin time to generate a nice queenside attack.

It is also possible that the tuning of the evaluation parameters is not what it should be.
A few months ago I introduced a stupid bug which messed up the automatic tuning of the evaluation parameters, recently I found the bug but since then I haven't done much to re-tune the engine.
It is difficult to use the parameters from a older version of the engine because in between many things have changed.
I'm working on a new version of the engine, totally rewritten from scratch, it is for a large part finished, but somehow I can't find enough inspiration to continue with it.
It is a lot of work to write an engine from scratch and each time I'm asking myself 'why am I doing this'.
Nowadays everybody seems to grab what they can from internet, and that is not exactly giving me inspiration.
