I posted it on Nov. 20, under the subject:
"Verified Null-Move Pruning, ICGA 25(3)".

The intensive discussions lasted for over a week, and I was present about
24h/day, answering the questions.

I suggest that you first review those discussions, as I can't afford the time to
discuss them all over again. If you don't find your answer there, feel free to
email me.
