Ok: I got "go depth X" parsing correctly, as well as "id name" and "id author" printing out upon receiving the "uci" command. And I put out a new release here: https://github.com/eboatwright/Maxwell/releases/tag/v3.0.8-1 with the new additions :D Thanks. I ca...

Yeah sorry: It supports "position startpos", but not "position fen". Does that need to be implemented? Not at all. When I issued the go depth 10 command it exited. I've never seen the go command used like that, only "go movetime X" and "go wtime X btime X". B...

At your page you write it can play only from the start position. At the same time it supports the position command. Is that not contradictory? After issuing the uci command it would be preferable if it displayed its name and version. Version number might be included in the exe name as well, to avoid...

Well, I have to ask. How did you install 3.2.0 under Arena? Because 2.6.2 was OK while this one does not move. I installed it in the same way as before (I copied it then renamed the necessary part, actually). EDIT: This is what I get from the command line: Error: LinkageError occurred while loading ...

Hello Dan,

I have not forgotten about version 3.2.0, only there are so many engines to test that sometimes you have to be patient till it's your turn.
BTW, how much improvement do you expect?

PS. By last version you surely meant 2.6.2.

I reckon Eubos is now around the low 2400s.

Hi Chris,

I don't understand what you write about hash size at your page. Could it be that even if I set hash to 256 MB it will use more?

It's OK as I am going to test v1.1 which does not have that bug (if I understood you correctly).

To assess its strength I ran a small test match under Cute Chess. It made an illegal move in all but the first game. It seems it often does not know which side it is playing, but even more weird things happen (see game 9). Here is the PGN. [Event "Thrawn_1.1"] [Site "?"] [Date &q...

Mida 2.3 exceeds time in about every 12th game. I did not notice such behaviour by previous versions.

Test already running.

Merry Christmas!

Hi Martin,

Good news. Tournament just started. Not likely to reach this week's update though.

Test starting as soon as I have a free core.

Here it works too. Also, the makefile is excellent, the exe it produces is about 20 % faster than the one at your site. Good job!

Yes, it was Berserk. And the solution has been found as well. Look here:

https://github.com/jhonnold/berserk/issues/518

Hello Giacomo, The makefile works OK. I have noticed something, though, which is present in previous Mida versions as well. After issuing uci from the command line, nothing happens, I have to type a lot of garbage before an analysis output is obtained. To make it easier to understand what I mean, he...

I have just seen Tcheran pop up in this week's Blitz rating list - very exciting. Thanks Gabor! A couple of questions if you have time - When releasing a new version of the engine, I've seen some authors post a new forum topic, and others post in their original announcement topic - is there a prefe...

No trouble at all, just leave it as it is then.

What does strategy do, does it make sense to change it and how to do it?

Is there a way to disable logging? That file has already grown to 25 MB.

I think I've come up with a better solution, which will work with the current stable Rust version and no manual file editing. I have re-released v1.0 (https://github.com/jgilchrist/chess-engine/releases/tag/v1.0) - downloading the zip + building should 'just work'. Indeed it does. Thank you. Is thi...

Yes, I used the zip from the release. I may have had succes by cloning the repository. But, IMO, the zip in the release should build to the same exe, to avoid confusion. Also, what if I want to revert to a previous version? Cloning the repository would not help then. I admit, that is quite a remote ...

As I am not a programmer I can't resolve this issue.

Well you can use his exe in that case.

Thanks for the hint Ray. It would have never occurred to me.
As I wrote, his exe is OK. But still. And it is verification to see that the provided exe and the compiled source gives the same output.

Hello Jonathan, Your exe seems OK. However, when I try to compile the source using the latest Rust I get this error message: Compiling engine v1.0.0 (E:\Sakk\compiles\Tcheran\chess-engine-1.0.0\engine) error: git describe exited with status 128: fatal: not a git repository (or any parent up to mount...

I suggest releasing various versions under 'Releases' for easier tracking and distinction.
