Hi,

Is there any simple EGTB source code? I'm curious to know how they create and make use of it. Especailly how they handle memory. Don't say Crafty I tried several times already.

Thanks,
Chang

Ernst Heinz's book (Scalable Search in Computer Chess) talks about endgame bitbases if you are interested.

It depends, on what you mean by "simple EGBT source code". If you mean, code that shows how to use Eugen Nalimov's EGTBs and his library:
Here [http://www.volker-pittlik.name/wbforum/viewtopic.php?t=931&highlight=egtb] I gave some code, that should be pretty much self explaining. Note, that at the start, there is lot of code that parses FENs - no need to understand that code. It is only there, to have a complete program.

If you mean totally self written EGTB creating/probing code: you probably won't find simple and easy to understand code.

You can practice on a smaller board, like 3x3. It's good for learning because you don't have to care about memory and can just focus on the logic and algorithm.
