On the idea of a 'dumb as a rock' qsearch.... Mine is even dummer. I don't use an SEE in the qsearch, but rather simply score the move based on the value of the attacked pieces minus the value of the attacking piece (if the attacked piece is defended). This will avoid some captures that are sound (because sometimes we have multiple attacks on the square), but it is quite fast and leads to a small qsearch. I also toss out captures that lose material or don't bring me near alpha. Perhaps this is making it too dumb, but even an SEE misses simple tactics as noted earlier in this thread. - Dan P.S. I did try an SEE recently and it seemed to be a loss on testsuites.... It was quite a bit slower (lost me 20% or something) so perhaps I was doing something wrong. I have not tried it for ordering captures in the main tree.
