I didn't say it has a huge NPS. I didn't see any information about this
on the screen.

My program has a high NPS (which helps a lot in blitz), but even if I
was 4 times faster I wouldn't reach Junior's depths.

I was thinking of a special way to descend the tree, and more precisely
being smarter in the quiescence search: not just generating captures,
checks, check evasions and promotions.

This could even lead to a slower program in NPS, but huge main lines as
we have seen.

BTW I think Junior was not the only program to have deep lines. I
remember a spanish program having similar depths (was it Toledo or Eugen
or both? I had games again them and lost against both!).

I don't see the point about 1/3 plies.
