For better comp-comp play I would have:
- Let the code be left alone or maybe removed some stuff that are unneeded for
pure play. Maybe added some commands to discard some evaluation code.
- Then made a automatic tuningtool.
- Collected position with eval/bestmove from some of the best comp-player
(Shredder/Fritz) for small ply depth (1 or 2).
- Let it run for tuning.
- Run matches against comps to tune the book, start with a pretuned book like
that Hyatt use on ICC now.

The first three points shouldn't take more than one day each. The two last
points get the rest of the four months.

I guess Crafty are tuned for human-comp play so the overall strength could
(probably) go down.
