Komodo seems a good engine and you even found a good binary of it. So I can only repeat my advise: Leave this shitty Rubi engine. It seems completely broken.
True. I would suggest avoiding the entire suite of OpenBench engines to be safe.

Re: UCI's readyok: A mistake or a misunderstanding

I agree that the wording is completely contradictory. To me it seems quite simple and logical: the engine should send "readyok" as soon as it is ready to accept a command . When calculating the engine is (usually) ready to accept the "stop" command, so it should reply immediately with "readyok". Su...

Re: UCI's readyok: A mistake or a misunderstanding

For the benefit of users, as a chess GUI developer, I humbly suggest engines’ developers use commands isready/readyok as pure ping/pong to help chess GUIs/users to detect the crash-stalls problems, regardless of the exact meaning of some paragraphs in documents. It is not a hard task for engine dev...

UCI's readyok: A mistake or a misunderstanding

For reference in my post, the following is the quote from the UCI protocol found here (http://wbec-ridderkerk.nl/html/UCIProtocol.html) * isready this is used to synchronize the engine with the GUI. When the GUI has sent a command or multiple commands that can take some time to complete, this comman...

Re: Commercial Release of Ethereal 13.00 (NNUE) for AVX2 Systems

... Alex, Ethereal was working ok in my system after the previous update by Andrew (13.07). It was all due to Banksia messing chess 960. I just got a new update I'm testing now (13.25) and all seems well with that one too. But Alex is running them under ARM x64 I believe, which might not be what yo...

Re: Commercial Release of Ethereal 13.00 (NNUE) for AVX2 Systems

Hi CMCanavessi, have you solved all the crashes experienced using Ethereal 13.00? Regards, AlexChess Nope. Andrew says there's a problem with Ethereal itself, so I'm waiting for a fixed release. ? We resolved your pondering issue if I recall. https://github.com/AndyGrant/Ethereal/commit/cc0fa3ef417...
