Thank you Sergio for running this tournament. Very much appreciated.

Hopefully we can have more engines from Brazil in the future.

Sorry to hear that. I downloaded WB2UCI. It has an option to send commands to engine using InitString. If you want to give another try, use the following below: [OPTIONS] Program=tucano_w64.exe InitString=option Threads=8\noption Hash=512\n This setup should send the threads and hash information dir...

Crafty approach seems interesting, I will take a look, specially how it defines promising split points.

I just released my engine with parallel search. I looked mostly at stockfish and demolito code. My implementation uses shared hash table. Each thread starts at the same time, and for even threads (thread id 2, 4, 6...) I change the depth to be searched so it creates different "search spots". The thr...

Hi, I am not familiar with WB2UCI, but it looks it should send the parameters using the comand line.

should the line be enclosed in quotes? e.g:

Program="tucano_w64.exe -hash 1024 -threads 8"

Hope this helps.

Thanks for the new release! A no popcount 64 bit compile would be nice. Guenther Hi Guenther, Sorry, this is probably unintentional, I didn't use specific popcount feature. I used the gcc compiler, I need to review the compile parameters. Let me take a look. Alcides. Guenther and Graham, I recompil...

Hi Guenther,

Sorry, this is probably unintentional, I didn't use specific popcount feature.
I used the gcc compiler, I need to review the compile parameters.

Let me take a look.

Alcides.

Damir,

Currently tucano is about 2750 in CCRL. I hope it breaks the 2800 mark now

Hello, Tucano 7.00 is available for download at https://sites.google.com/site/tucanochess This is the parallel search version (shared hash table implementation). This version should be much stronger than 6.00, about 90 elo on fast time controls. Main improvement come from evaluation tuning using Tex...

Thanks to all contributors. Learned a lot from chess wiki !
