Hello talkchess enxadristas! (enxadrista is portguese translation for chess player). This is the release 1.0 of a new chess engine I wrote in C#. The intention is to provide documentation in Portuguese of the techniques in the form of comments in the source code ! I am the author of Tucano chess eng...

C++ vs. C; OOP vs. Procedural; Global vs. Local. These are different and unrelated things. You can use C and write OOP. You can use C++ and use Procedural. You can use lots of globals or none, in C or C++. Whatever you do, never be religious about it. Writing code that has 0 global variable for the...

Another loss for Critter, this time the perpetrator was Tucano 7. Here's the game: [pgn][Event "006 - Junior League"] [EventDate "?"] [Site "RYZEN"] [Date "2018.02.11"] [Round "1"] [White "Tucano 7.00 x64"] [Black "Critter 1.6a x64"] [Result "1-0"] [TimeControl "120+1"] [Opening "Queen's Indian"] [...

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.
