(i tried it with deppfritz7, maybe it works with crafty too. does crafty delete the hashtables bevor it starts thinking?) after that,let fritz filling up his hashtabs, while let him thinking a long time (30 min) after that take back n*2 moves,n=1,2,3,4... (with white to move), and you will see that Fritz has enough informations saved in his 'brain' , that he can show you each alternative move to be lost too ....
