Subject: Re: Question on Probing Hash Table for Best Move in QSearch

Go up one level in this thread


I probe the hashtable in QSearch with depth 0, and store qsearch nodes with
depth 0 into the hashtable in my program Nullmover. If the move is above beta
then I produce a cut off immediatly.

In all QSearch nodes I generate the captures/queen promotions and then
selectsort these moves. If a move is the same as the hashtable move then I sort
at the top of the list.

This seems to work in allmost all positions slightly (10%) faster then when I
don't use hash in QSearch at all.
