Chess Piece Valuation

The values of the squares and pieces seem to vary depending on the location of the King and other pieces.

yes the 1.10 on the bottom and top comes from the king being able to castle on that square so having 2 extra moves. Also the value of board changes as you remove pieces, If you take of a bishop its coloured squares are worth less.

I like this game, shows how important control of centre is even in prog vs prog games, the whole game is rybkas opening book too... scairy

Are you trying to figure out how you might be able to progam a computer to play chess? I believe that is going to be a difficult task from scratch.

I'm just trying to write the evaluation function (i think), what a computer would use to score a posistion, and by the looks of things I'd need a program just to do that. Also it might be possible to derive openings with these tables, they might be rubbish but its possible.
