What algorithms and heuristics are popular in computer chess?
What is an accurate way to evaluate chess positions?
These questions were asked right around the time the site opened. The first one currently has 3 close votes, all for off-topic. Any thoughts on whether it is on topic or off topic? Per the comment link, this is off topic for the site: https://area51.meta.stackexchange.com/questions/5056/can-i-ask-questions-related-to-chess-ai-and-algorithms.
While I think there is a fairly large population of programmers on the site currently, I think that the Area 51 discussion is still on target and questions like this are off topic. I'm not convinced that the questions would get good responses on a site like Computer Science, but those answers will almost certainly be better than what chess experts can come up with.
