A chess program has been developed which plays good chess (for a program) using a very simple structure. It is based on a [[Brute-Force|brute force search]] of the move tree with no [[Pruning|forward pruning]], using [[Material|material]] as the only terminal evaluation function, and using a limited positional analysis at the top level for a tiebreak between moves which are materially equal. Because of the transparent structure, this program is proposed as a technological [[Various Classifications#:Category:Benchmark|benchmark]] for chess programs which will continue to improve as computer technology increases.
