Statistical analysis of the relative strength of chess positions

Abstract

The statistical value of a piece on its occupied square of origin is extended to those squares controlled by the piece. A cumulative strength metric applies to each square controlled by a piece. The computer model, Relative Strength (RS), predicts the next move in an opening example from the world computer chess championship. A predictive rate is significant. RS is a teaching aid for recognition of tactical chess patterns based on positional patterns. From implementation of RS, recent advances in external computer storage of chess positions include invention of the radix hash sort.
