As part of a demo for a rules engine I'm dreaming up, I'd like to do an evaluation of a chess board that communicates each side's general strength at that point in time. Advanced things like predicting moves or establishing mate patterns are way beyond the scope of this idea; I only need to think about what's in front of me for now!
I also do not need to establish precisely how to reduce board strength to a number; that will be a lot of tinkering, this way and that, to find something that seems reasonable. For now I just need to figure out the top, say, 3 elements to deciding how strong or weak someone's position is on the board.
My current thought is, in general order of importance:
- Material (in pawns, so rook = 5, knight = 3 etc)
- Open attack paths on the center of the board (critical area, goes to development)
- Total attackable squares (development)
Am I missing a particularly important element in this evaluation? Am I attempting to measure it wrong?
