This sounds interesting.  If your chess program is sufficiently small internal
loop, it can be nice to turn it into kind of benchmark and send me. The I can
investigate whats going wrong.

In simple internal loops we should not be much worse unless we have some good
purpose :)

That can be nice too. (with kind of source:)
