it would not make any difference whether I include x-ray attacks for queens or not, evaluate_threats() still would not "see" it. That's what I meant.


No, x-ray attacks for queens are used to evaluate mobility not threats.

Besides evaluate_threats(), queen attacks are especially important in king safety eval.
I would first double check whether it would hurt in king safety to have included x-ray attacks for the queen attacks. Especially the "safe queen contact checks" part seems to be very critical. I will take a look at it tomorrow evening.

It's bed time now. Thanks for anwering. Good night. Wink


I am curious how you "double check" without testing the tweak and verify with real games if it hurts ot not Question

....anyhow good night.
