Subject: Eval tuning based on LCTII results

Hello.

I recently ran the LCTII test positions against my engine.  Suffice to say it
did badly.  It solved almost all of the tactical positions rather quickly (where
a material advantage or a mate was possible).  However it did not get many of
the others.  This tells me that it is too materialistic (since it does not miss
any ways to grab pieces) but it has nowhere near enough positional knowledge.

I'd like to use the information from the ones it missed in order to better tune
the eval.  However, I do not know enough about chess to understand why one of
the solutions is the best in some cases.  Has anyone written a kind of "here is
the reason the solution is the best move" document about this test suite or any
test suite?

I'm currently re-running the test with a larger lazy-eval and delta pruning
window... If anyone is interested I will post the results here.

Thanks,
Scott
