'''[[Main Page|Home]] * [[Evaluation]] * Evaluation Hash Table'''
An '''Evaluation Hash Table''' may be used in a similar fashion as the [[Transposition Table|transposition table]], that is using [[Zobrist Hashing|Zobrist-]] or [[BCH Hashing|BCH-hashing]], to cache various computational expensive positional evaluation scores and flags. Despite the fact that the transposition table entries may contain evaluation scores as well, a tighter, dedicated evaluation hash table with its own replacement policy may gain a considerable amount of additional hits.
