Do less SEE pruning in qsearch Current master prunes all moves with negative SEE values in qsearch. This patch sets constant negative threshold thus allowing some moves with negative SEE values to be searched. Value of threshold is completely arbitrary and can be tweaked - also it as function of depth can be tried. Original idea by author of Alexandria engine.
