Hi all,
I have just released a version 0.7 of Ceibo. Changes are as follows:
Board Representation: Bitboards! (old school; no rotated/no magic)
Movegen: completely reworked from scratch
Evaluation:
added king safety (my engine actually tries to protect the king ! how about that? )
added more pawn structure terms
Null Move: tuned parameters, removed useless conditions and added new criteria
LMR: tuned for longer Time Controls
fixed issue where moves to mate where incorrectly reported
removed bugs and added new ones
+ many minor changes, enhancements, code clean up, etc
Pls find below a Direct Download link to Ceibo 0.7 or go to the Downloads section of my site:

Thanks! Fede

Hi Graham and team,
It seems Ceibo 0.7 refused to work on the first match of D8. Lars's Xeon had no issue with it, but Dany reported a DLL issue due to a missing C++ Runtime library. If that's the reason why it didnt work, I have compiled a new version which removes that DLL dependency.
Pls try this version if possible and replace for D8.

Instead, if the issue is that the CPU does not support BMI1 pls try this one:

Thanks.
I had the dll with the version I was running.
I downloaded the noBMi2 exe and it runs on my old i5 for Division 8.

Uh, Fede, I have just read your post, I would have started testing Ceibo already if I knew.
Cheers,
Gabor

No worries Gabor!
Glad to hear you'll start testing it.
