Im confused, how do you reckon you can lookup table all the possible moves? Maybe i misunderstand you but wouldnt that require knowing all possible games and putting all possible board positions in the lookup table? (Which I think would mean that you could solve the problem of the prefect game.)

    Nah, you just need to have a board with one piece on it and generate all possible moves for that piece from that postion. Then put that data in the lookup table and do it again for the next piece or position. You'll still have to do a little runtime work like check that the piece isn't jumping over other pieces (except for knights) and isn't landing on a square already occupied by a freindly piece, plus few other special cases (like pawn attacks). For the most part, though, lookup tables get the hard part done.

    I thought of this as an individual move validator. "Is this move legal?" sort of thing.
      It's a small lookup table. Just fifty billion possibilities. Nothing big :)
