Well, library or not, you didn't write/calculate the tables, so it is not really your program finding the correct moves when it reaches that part of the game. I think the majority considers chess solved at that level, so there's no good reason to spend time doing lots of special heuristical programming. However, it is still cloning IMO ;) >If Nalimov would have written a chess engine, where TB was just one part and >would have made it public like Bob does with Crafty, then copying just this part >of his engine would be a (partial) clone for me. Nalimov didn't do it that way >though and it is my understanding that if you ask him nicely, he will give you >permission to use his code in your engine and he would not see this as a clone. Whether or not Nalimov made an entire engine around the tables is not really significant I think, I could just argue that you are not cloning Namilov, but instead the first program to use them;) Basicly most of the programs are clones of each other at some level, the ideas and algorithms are much the same, only the imlementations of them and the weights differ. >On a related note: It wouldn't hurt, if someone would really not depend on >Nalimov's TBs but code their own.
