Hi Charles,

I've been all over the map on this one, I think.

BTW - if you extend check-ing moves, eg., 3/4 ply, sometimes they dont get
extended - so in that case, you may want to find mate in quies().

I have always had mixed feelings about all this. On the one hand, I agree with
Mr. Hyatt and dont want to clutter the already very erroneous qsearch() with too
much. On the other hand, I hate the idea of search depending upon such a poor
'definition' of 'quiet'. [ie., checks near by, or worse, your mated!]

The trade off of course is speed. When I use checks [and checking moves] in my
qsearch, average search depth goes way down, but still plays ok because the
information is more stable i THINK

Which has me puzzled a bit... how does a slow searcher like GES ever win against
the likes of these speed demons. [believe me, its not because of positional
prowess] It must be because all TOO often, all that interesting stuff that is
'seen' by the faster searcher [due mostly to selectivity, i guess] isnt really
reliable. ie,. quies() isnt returning quiet positions...

thoughts welcome, nay coveted...

-David
