Re: Leela Chess Zero 42565 vs Stockfish 140619

Pondering makes sense when playing against Leela on a many-core machine, as Leela wouldn't use many CPU threads while thinking, and all other threads would then go to waste. Likewise the GPUs would be idle during Stockfish' turn when Leela is not pondering. If Leela need two unshared cores, you can ...

Re: UCI2WB 4.0

The zombie engines apparently are a consequence of the killing by WinBoard of the adapter, before it can relay the 'quit' to the engine. This is truly amazing, because it still happens with /delayAfterQuit=1 (i.e. 1 sec). I had UCI2WB log its reception of GUI commands and its sending of commands to ...

Re: UCI2WB 4.0

Removed the empty line and add "I", save, OK. But then when I press edit engine list again, I got same image above, so my changes were not saved. This is weird. I get that behavior too, at least in when I close WinBoard (with Save Settings on Exit on), and start it again. When I just click Edit Eng...

Re: UCI2WB 4.0

A function like this (from UCI2WB) looks like a buffer overflow waiting to happen: Umm yes, that is a bit sloppy. Especially as the buffer size is not extremely generous; for reading from the engine it is 1024 bytes, and although I have never seen an engine spit out a PV of more than 200 moves, UCI...

Re: UCI2WB 4.0

It seems that the first line in the engine list has become an empty one in the process of editing it. Edit the list again and delete that line. WinBoard has always insisted that you specify both engines in the Startup Dialog. Even though you might not plan doing engine-engine games at all, which is ...

Re: UCI2WB 4.0

Doesn't ticking 'Just view or edit game files' work? In principle you can also type an engine line in the comboboxes, but as that is not put in the list you probably wouldn't want to do that. About the crashes: do they only happen when you run multiple instances of WB on the same tourney? I tried a ...

Re: UCI2WB 4.0

Thank you for testing. Best way to remove engines is by Engine->Edit Engine List, and just remove all the lines with the engines you want to delete. Strange that WinBoard crashes. I did not really change anything in it that should be executed when running games and tournaments. (Just redesigned some...

Re: UCI2WB 4.0

I now also updated the WinBoard executable in the AA package. This fully implements the new method for position setup in the mode /pieceMenu=true (which no longer involves a piece menu!). To get it in that mode you might have to run it once with this as 'Additional option' (because your saved settin...

Re: Playing the endgame like a boss !!

You cannot seriously have thought the program would have written itself, can you? What should be next to qualify as 'Zero'? Should it also build its own hardware? Just take a scoop of sand from the beach, throw the FIDE manual on top of it, and wait until a Chess-playing machine emerges...

Re: UCI2WB 4.0

I finally got to fixing the problem the new UCI2WB had with playing games from an opening line. (By having the engine thread also handle appending of moves to the game, so that it now pretty much handles everything. The the GUI thread is only responsible for immediate execution of force, quit and mo...
