Positional play is just an aproximation. In chess, the only possible results are 1-0 1/2-1/2 and 0-1. If it were possible, a program would only need these 3 "positional evals" to play chess. Just scan the whole tree, and choose the move leading to victory or draw, if no victory possible. But chess is too complex for this, so we have to aproximate "how far are we from the victory, draw, or losing". This is what positional knowledge tries, and the only limit I find for this is the time (and space in memory) you want to spend on the evaluation. The more particular situations you take into account, the more accurate the eval is. The deeper you go in the tree, the less you need this "positional aproximation", cause you are closer to the real eval (1-0, 0-1, 1/2-1/2) you are. Just my opinion, José C.
