OT maybe- I want to learn how to code a basic chess game

I am really sorry to write  in this general section  but looks better than off topic to me.

I am a developer and want to have fun with my beloved game.

I know there are places where can i find code of places where can i find already made code( github repositories) but i would love a tutorial/book/ resource that teaches me how chess work under the hood, just to have some fun (possibly in java desktop or android ) would like it

Honestly just study the C++ source available in various Github repos.

You can test and disassemble with BlueJ or whatever you prefer.

yep thanks, I can find it on whatever language on github

well actually I found some youtube video, after changing some k word
