No - but I say it does many NPS. :-)

Maybe it has no iterative deepening?
Whatever the method is, when we have the engine, we will find out.
Like Bob always says: some data is better than no data.
And I guess the game I have posted with the search-depths IS more data
than I had before...

Maybe.

Right. But I have also watched games of Toledo AND Eugen. From what I
have seen this was not similar.
Eugen and Toledo are strong programs. But junior's main-lines seem to be
of a different quality referring not to the playing strength but to the
length and the speed.
Only old Lang-programs remind me on this...

:-)

Vincent tried to explain it to me, but I can only say that I understood
1/3 of HIS explanations although Vincent is a genius in impressing with
words :-)

Whatever it is, I am sure it is worth studying it !!

The way junior does it must be different for a long time (as I said, in
Paderborn 1995 I have seen the same behaviour , only the program was not
that strong and knowledged. IN PADERBORN i have seen these massive NPS
or positions on the screen. Junior paderborn SHOWED them on the screen.
Not junior Paris.).
