Hello Albert,

You are absolutely certain that Hiarcs 7.32 retains the hash-tables between
moves? I have played against it at 40/2 and I have experimented as you state
above by taking back a move and forcing Hiarcs to redo the move; however, I did
not get an instantaneous response as apparently you did. It still took Hiarcs a
fair amount of time to re-make the move. I wonder what time control you were
experimenting with, and if your result was possibly due to a faster time
control?>

Regards,
Mel
