I don't disagree. The parts that always cause me the most concern center around the evaluation and search. I didn't look at his search carefully at all, but I did look at the evaluation, and that has too much copied code... There may be significant search code copied or not. But copying either is really copying the "personality" of the program... Several have started with gnuchess, for example, but by the time they claim it as their own and distribute something, the important stuff has been re-done by the person doing the work, rather than just copied... > >Dann Corbit seems to have suggested that starting with an existing search >algorithm, such as alpha/beta, might be a prudent way to get started. > >It is not so clear about the position evaluation [and maybe move generator].
