Hi there!
2 years ago I released a small project on chess evaluation,
the LittleChessEvaluationCompendium, still available here: http://www.winboardengines.de/doc/LittleChessEvaluationCompendium.pdf
Now, since I have come up with some new, and possibly not uninteresting ideas, I have decided to release a small addendum, available for download at: http://www.winboardengines.de/doc/addendumlcec_2012.pdf
New things in the addendum:
- x-ray attacks
- complementarity (optimal spread)
- split ratio for control of black and white squares
- groups of pawns; scoring of groups of pawns
- more on double, isolated and backward pawns
- values for pawns on files and ranks (apart from space advantage)
There are also some suggestions on pruning, but since I am not a programmer, I do not know if they are sensible at all.

Best regards,
Ludmil
