I don’t really understand your question, but try to answer my best. I am
surveying how and why bad performance of my program is (so bad). I hope to
narrow the gap between it and Crafty from over 20 times slower to around 5 times
slower. I am applying, coding and re-checking any techniques I could know and
always compare them with Crafty. I have learnt some basic techniques from some
old books and TSCP, but almost all advance techniques of searching from Crafty –
I admire Dr. Haytt about it.

I am a researcher (but not in this topic), therefore my purpose is not to build
“the king of chess”. I do all thing just for my curious and fun. Then I hope to
help some my students, both theory and practising by giving them some good
instructions how to learn and how to implement a chess program. I also hope to
make some new contributions in Chinese chess, on which much fewer people are
working and it seems not to be treat as a topic of science.
