Re: Stockfish archive

Very hard to change the game in a mobile device. Connect your iPhone to iTunes, copy the game from the Documents folder. Use your computer to do the changes then copy the new file back.

Re: If machines can beat us at games, does it make them more

Isn't it bizarre that the article claims their computer searched for a week and it didn't reach a depth of 20 ply on that problem? To me that sounds like something you'd expect from a computer from the 60's. Any computer today should have no problem reaching 20 ply in seconds. A recent dev version ...

Re: Cfish 8 121516 for the macOS

Michael,

The Stockfish code has skill levels implemented, it's done by randomly selecting a move from multi-pv. The code is not available in Cfish because Ronald didn't port it. Search "#if 0" in search.c, and you will see it. Maybe you can help him?

Re: Cfish 8 121516 for the macOS

Thanks for the update. But in your code, you can just do:

2^((x-1200)/100) * 64

where x is the rating you want. The code you have lead to floating errors.

Re: benchmark new smartphones:

I also have a Xiaomi device, and it was the best given how much I paid. The other one I had from Samsung similar priced, could barely move.

Re: Help for Syzygy probe?

Thanks to Basil and Greg. I understand I have incomplete database files, in fact I don't have any 5-men file. I was curious why two different programs, giving the same physical path and FEN would return different results. I am using the Fathom tool. I compiled your code in the apps directory. I only...

Re: Help for Syzygy probe?

-2 is correct because the position is lost for the player to move. The Python package was correct to return the value. However, when I gave the same path and FEN to Fathom, it failed to return WDL. My suspicion is that there is a bug in the fathom code, but not 100% sure. That's why I posted here. ...
