Btw, what I'm after at this stage is nothing more than an overview of how the evaluation is done. For example, it might be (and I hope I'm proven wrong on this!) that it's nothing more than, for each position evaluated, a chunk of code asks if a particular positional aspect (e.g. past pawn) is present, another piece asks if the next positional aspect is present, and so on. Any kind of answer from anyone would be useful to get us started here - I don't think any of us will mind if the first poster is not very accurate. I think that once the ice is broken, we'll start to home in on what's happening fairly quickly. -g
