  Can't check it now (I'm at work), but I don't recall such an increase in nodes
searched in my program when I added qsearch. I guess you have something broken.
If you post your code here so we can have a look, we can try to help you.
  Anyway, remember you can cut the search and return beta in case the static
eval is >= beta without searching anything at all. And remember that, if the
static eval is > Alfa, you can set Alfa = static eval.

  Hope this helps,
