Illegal moves

[CPagador]

Hi,

I see that Talento loses many games by illegal moves. I am attaching a pgn with some examples.

Thank you so much for contributing my using your time to test my engine, that is greatly appreciated and I will make sure to check that out later today.

I think the issue was solved on the latest release v0.1.2, there's a binary file for linux and for windows or you can also compile it by yourself with cmake, I'll leave this issue open awaiting for feedback, thank you once again.

Unfortunately, there are more games with illegal moves.

Thank you for your reply, that's interesting, it always happens after enemy promoting to queen so I assumed it was related to that and I was right and found a bug where it would not read the promotion right but fixed it, I'm going to investigate further.

I've reuploaded the binary files in the 0.1.2 release, sorry to bother you but can you check with those ? The issue should be fixed, I'll search for other bugs that might cause that problem tho. I've tested with the positions on the last PGN and couldn't replicate the illegal moves anymore yet they were there on the older version, maybe it's the compiled binary that is outdated ? Although I made sure to compile it before upload it. Anyway, if you could check it would be awesome so I could close this issue.

Problem persist:

Weird, I can't find the root of this issue, and when testing locally my new engine doesn't make any more errors, if you send the engine the command uci does it print out 0.1 or 0.1.2 ? if it prints 0.1 can you download the files from the latest 0.1.2 release on this github and check uci command and if it still makes illegal moves ? thanks and sorry for your time, I am trying hard to find the root of this issue

I compared the binaries with WinMerge and also with MD5sum and all of them are different. Anyway, I redownloaded the latest 0.1.2 version and it shows that version when using the uci command also the size of the file is different from the others, but it keeps doing illegal moves.

Alright, I'm continuing to try to find the issue, if possible could you tell me where can I get a copy of another engine and opening books if you used some to try to replicate it myself ? Thanks

[CPagador]

You can find many engines here:

I use Winboard 4.6.2 GUI, with a common polyglot book for every engine, except for few of them who do not accept external books.

I really can't replicate or find the root of this issue, I'll continue the development normally since I've lost quite a bit of time with this but leave the issue open in case it starts to aggravate or become more discussed, thank you so much for your time and effort put into this, I hope I can impress you in the future with my engine.
