Hello my friends,
I'm once again happy to announce a new release of my chess engine Freyr. The old evaluation function and piecetable settings were very wrong in the previous versions, now I changed them to very simple ones and things seems to be much much better. Also my old quiescence function was poorly functioning, it was rewritten to.
Note : I changed the format of the opening book so please delete all old opening books for Freyr.

Best Regards,

I'm looking forward to examining the source. I rather enjoy your coding style.

Of course I forgot to include something.
learn.txt is a text file used to control the opening book selection
a simple example:
***** start of learn.txt *******
[white]
[avoid this]
e4 * f4??
[just a test]
d4 d5 e3!! Nf6 Bd3!! c5 c3!! e6 Nf3!!
[black]
e4 d5!!
***** end of learn.txt *****
where moves can be marked with ?? ? ! or !!
consider this a secondary opening book with higher priority than the standard one
it can be used to force freyr play some openings, so far I don't use it but I have plans to
