If memory serves me right The King clears hash between moves and therefore dosn't need as much ram as other engines. Evidence... computerchess leaves more questions than answers, if i played 10.000 games with 32 Mb for the king against various opponents and repeated the 10.000 games with 64 Mb hash and the 32 Mb setup had the better score, some people would still want evidence :) I, like Thorsten am a big believer in watching the games you test, in order to get a "feeling" for strenght's and weaknesses instead of just looking at the results, both have to be combined IMO. Therefore i can't give you any evidence, but just my opinion along with other peoples equal observations regarding optimal hash settings for the king. Jonas
