Note that Sjeng for some reason comes with ~250MB total hash as default! Take a look into the "Sjeng.rc" file please. Also we dont know under which GUI you played Sjeng but from the output I assume it was Arena? Moreover we dont know if you installed Sjeng as UCI or WB under Arena? In a post of the Arena beta test Forum someone mentioned problems with pondering of Sjeng 12.11 under Arena but he also did not mention in which way he installed it... Normally UCI versions' hash sizes should be managed by the GUI but sometimes it is necessary to delete the special "ini" files of programs which are both UCI+WB (in this case ".rc"). Regards, Günther
