Question: How much does positional knowledge add to a chess player's elo rating, compared to having no positional knowledge at all? For example: Chess player/program A does a full-width search 8 plies deep on every move, but looks only at material balance. Player/program B does the same, but also applies theoretically perfect positional knowledge. How much higher is B's rating? I have done a few "thought experiments" on this, and I've made the guess that positional knowledge is worth very roughly 500-600 elo points. Would anyone else care to give their estimates or opinions? Has anyone done a rigorous test to determine a value? -Jim Phillips
