Re: Maiden Release of Ditto - FF2 Beater && it's FREE

Thanks a lot for Ditto! I like the idea of a fixed depth in search for weaker play. But in your sources you have commend out the Depth UCI option in search.c Can you explain why? //Limits.depth = option_value(OPT_DEPTH); Of course when you are in analyze mode (infinite time i.e.) you need to check f...

Re: Give it to us - we want Stockfish

Still no link to Smallfish source code anywhere. On the other hand GPL doesn't allow additional constrains added to the license which the Appstore does with their Terms of service. So in theory no GPL software on the Appstore. But i'm happy to see some iOS apps got lucky and sneaked into the Appstor...

If you "distribute" stockfish along with your own application, troubles start.
Not 100% correct. If you use Stockfish as a binary which your software side-loads then GPL doesn't kick in. But if you need to compile the Stockfish sources (like on iOS) then your project is under GPL too

Re: Stockfish licensing question

Sites like Chess.com and Chessable use Stockfish, but I don't see them offering me their codebase! Anyone know the truth of this or care to clarify? They load Stockfish as a binary on their servers I guess then their code isn't under GPL automatically And btw Lichess ...is open source and they publ...

Re: Stockfish licensing question

Make it free GPL doesn't mean your software has to be free. GPL doesn't have a price tag. You need to make your project under GPL too if you included Stockfish as source code and available as source code on request. Note: Some marketplaces like the iOS Appstore aren't GPL compatible even you see GP...
