Re: New engine: CederChess

In the next version I'll implement better time management.

Re: New engine: CederChess

I may have underestimated your hardware, Gabor According to https://computerchess.org.uk/ccrl/404/about.html you use a Intel Core i7-4770K, while I have a Intel Core i7-1165G7 in my computer. So I made this processor comparison: https://www.cpubenchmark.net/compare/1919vs3814/Intel-i7-4770K-vs-Intel...

Re: New engine: CederChess

Thanks for adding CederChess 2 to the list, Gabor

I do have some improvements in mind with the current architecture. I will work with these next winter.

To make a huge jump, I think a new architecture is needed.

Re: New engine: CederChess

Thanks Gabor, I have mentioned 1400 ELO, but I can see on the CCRL Blitz list that the ELO scores are lower than they was a couple of months ago - at least for the weaker engines. Based on many games against the engines Ozwald, Phalp and Quokka, I estimate CederChess 2 to have an ELO in the 1250 ran...

Re: New engine: CederChess

Hej Gabor (or another admin),

Did you see my request for CederChess 2 ?

My guess is that is about 200 ELO stronger than CederChess 1.

Best regards,
Claus

Re: New engine: CederChess

Hi Gabor, I have been working a little on my chess engine and version 2 is ready. I think the expected ELO increase to around 1400 justifies a new evaluation. It can be downloaded here: https://cederberg.dk/cederchess/ There is both a single cpp-file and an exe-file. Looking forward to see it on the...

Re: New engine: CederChess

I would appreciate that, Gabor. Thank you. Hi. I'm the author. I can't remember why I removed the exe file, but now it is back on https://cederberg.dk/cederchess/ . There is also an exe file for version 2. Even though it is a snapshot version and not a final version it is quite stable and the sourc...

Re: New engine: CederChess

Thanks for the two games, Gabor I can see my engine actually tries to cheat by trying to promote a bishop (first game) and a rook (second game) to a queen - the engine returns "bestmove g5d8q" and "bestmove a5a8q". It seems like Arena just ignores the "q". I can now rep...

Re: New engine: CederChess

Thank you very much, Gabor! I have difficulty mapping the processing script output to actual games in the PGN file. In the PGN file only 2 games out of 510 have "illegal move". And when I load these games into Arena, it seems like it is the opponent who makes the illegal moves. Anyway, I'm...

Re: New engine: CederChess

Hi Gabor, I'm happy you have it up and running. My time control is very simple and I took a safe approach "better too fast than too slow". I hope this is not a problem? The engine is very simple right now and I have many ideas for improvement. Among them are better time control. But I woul...

Re: New engine: CederChess

Hi Gabor, The 32-bit dialog looks fine. So if you can use the 32-bit version, then just use that. Yes, "cp -39" looks weird, but it is because my evaluator evaluates that after 6 plies (3 moves by white and 3 moves by black), the position is 39 centipawns better for black. This is how my e...

New engine: CederChess

Hi,
I am new here and this is my first post.
I have an engine which I hope can get on the CCRL Blitz list.
Here is the website for the engine: https://cederberg.dk/cederchess/
I expect it to have an ELO about 1200 only. It is my first attempt and my hope is that it will be better over time.
