Most of the time I cannot log in through my VPN. This is a rare moment when I can. And I am going to use it to write that as long as this situation persists, I will not post on this forum. My lifelong habit was to avoid discriminatory environments, and TalkChess became one of them. I will never acce...

you can use lines from here: https://github.com/nescitus/cpw-engine/ ... r/book.cpp

PS. don't expect any reply from me. loggin in through my VPN does not always work. Shame for the people who forced me to use it, shame for this forum.

JohnWoe, either You are including comments in Your LOC count or my regular expression to count lines of code is broken. It tells me that Rodent IV is roughly 8500 lines of code, excluding comments.

This is interesting. A friend added FRC support to Rodent and after playing a few games I know that its eval is sub-optimal for this chess variant. My engine seems to be reluctant to take central space in FRC, even though in normal games it does so willingly. The reason is that it does not have a bi...

If I play A1 then if the opponent play B2 then I play C2 if I play A2 then if the opponent.... Despite whatever Kotov said, human calculation is much more messy: 1) My bishop move attacks o...

Note that if you want style and don't care about strength it's possible Rodent IV personalities will never be as good as Rodent III ones, and in this aspect there's no reason to upgrade as IV's improvements would be irrelevant for these purposes (III's personalities could be made stronger at will) ...

Is it possible to use Rodent III personalities in Rodent IV? They would have to be converted. I changed engine name to indicate that incompatibility. Three most important differences are king tropism (from Hakkkpeliitta), space evaluation (which I added specifically to be able to create Morphy pers...

"Planning" engine would play boring, schematic, uninspired chess. How do I know? Because such a sad thing has been done to beautiful game of go, see https://www.gnu.org/software/gnugo/
