Yes, it evaluates that position as -1.08 for white. Actually there was a bug and
after fixing it, it evaluates the position as -0.40 for white, and solves the
initial position at ply 3 instead. I don't think it's incredibly speculative. As
the king becomes more and more in danger, the material difference becomes less
and less important. I guess it's a matter of deciding how much danger the white
king is in; King of Kings thinks that it's in a lot of danger.
