Subject: null-move

First of all, I hope the forum will continue in some way!

Before it is gone, I have a question.

I wanted to check my null move so I tested if the null move would create a
cutoff, and after that I did the normal stuff. So if you have a cutoff with null
moving you are almost sure you will also get a cutoff with the normal proces,
except for zugzwangs of course. But this wasn't happening all the time when I
tested it, and usually the values involved from what I got back from nullmove
and from the normal process were just a few centipawns in difference. Could this
be because of search instabillity? If it isn't a bug in my program I had the
idea to search nullmove with beta-MARGIN in order for the value returned by null
move to bridge the few centipawns gap. And taking MARGIN the few centipawns. But
I'm not sure if that is correct. Can someone shine a light on this?

Thanks, greetings Bert
