I guess it is found 11 search. But this takes some time...
When I set selective search to sero, and setup pgn2, it is not finding
the move anymore in 1 or 2 minutes but it needs 15 or more !

If M means MOVE this could explain why the main lines have a pattern on
the base of 2 .
This would correlate better !
If you believe M means ply, than it is not obvious to me why the machine
has pretty good main-lines, deep, after 1 second computing time and
M=sero !

>What do you call the "log file"?

Call it SENDINFO or what crafty is writing in his log-files. It prints
out the main-lines, search-depth and evaluations in an ascii-file.
The first dedicated machine doing this was Saitek Leonardo.
Later some Novag machines made it possible. This was a big and important
thing for me because I don't always have to starr on the LCD !

We will discuss this too....
