Re: Bug in my engine

Steven, I could reproduce a few full test games with that bug yesterday and will post a link to it in a few minutes here. The main post will be in the BanksiaGUI thread in the general forum, because it also refers to a bug in the current Beta. I will also add the logs for download at my RWBC site. ...

Re: Bug in my engine

Thanks Ronald. The numrepeats variable should probably be called numoccurences. It counts the number of occurences of the position in the stack, not the number of repeats. So 3 occurences is equal to 2 repetitions which is why it's >= 3 and not 2.

Re: Bug in my engine

Thanks a lot for doing the tests with Raven, Guenther. I suspect it's a problem with the TT and mate scores. I'm going to try not using the TT when the TT score is mate and see if it fixes the bug. If it works, it shouldn't affect playing strength much, I don't think.

Re: Bug in my engine

Hi Ronald,

I've thought about that, but I paste the fen from before the repetition started so the threefold repetition should still work the same. Also, when I try it in winboard, I paste the full game and still can't reproduce the problem.

Re: Bug in my engine

It hasn't happened in a CCRL game that I know of, but i think that's because they're adjudicated before it'd happen. I haven't had any reports of it happening to anyone else. Weird how it happens on your machine but not mine.

Re: Bug in my engine

I was trying it with my local version which has some differences to 0.60. I just tried it with 0.60 and it still gives the correct mating sequence. The lichess raven is also my local version but I know the bug existed in 0.60 as this bug has been ongoing for months. I'm on Windows and I'm using the ...

Re: Bug in my engine

Thanks for the replies. H.G. Muller, there's a client for lichess that allows you to run your engine on it. The client is here: https://github.com/ShailChoksi/lichess-bot I don't use adjudication in my matches, so the games aren't ending due to adjudication. Like I said, when I run a local match in ...

Bug in my engine

I've got a pretty serious bug in my engine but the problem is it only seems to happen on lichess and I can't reproduce the bug locally. In a lichess game, quite frequently, when it gets into a winning position, it will draw by threefold even though it's heavily up in material or even has a short mat...
