Clovis v1.0
My second attempt at a chess engine!

First attempt was promising, why abandon it?

First attempt was promising, why abandon it?

I had done roughly the first half of development in Hopper without really looking at other engines or following standard practice, so extending some functionalities were only getting more and more difficult. After I learned about bitboards, I had always wanted to go back and start from scratch because it seemed easier to start fresh instead of rewriting everything. Also I thought Clovis was a cooler name.

Exe says it is version 0.7. Anyway, I recommend including version in exe name.

Accidentally found this:

Fridolin 4.00: https://sites.google.com/site/fridolinchess/download

Experimental NNUE evaluation. I haven't tried it yet but judging by the size of the binary it requires an external NNUE file. Whether that is SF or other, I don't know.

Hi all,

I'm happy to announce that today I released Fridolin 4.0 at https://sites.google.com/site/fridolinchess/download.
Based on self-play tests, I would expect a playing strength improvement of around 70-80 Elo?! This is mainly due to many bug fixes.

The most important changes are:

(new) Aspiration window search
(new) material hash (endgames recognition)
(new) NNUE support (experimantal)
(chg) switch to C++11
(chg) many refactorings
(chg) removed Nalimov tablebases
(chg) pawn hash from global to threads
(fix) multithreading reliability
(fix) premature bestmove while pondering
(fix) crashes due to size limitations

Best regards,
Christian
