If you were running this event using 16 cores would you turn ponder on? If not, why?

If you were running this event using 16 cores would you turn ponder on? If not, why?

I have 6-core i7-3960x CPU, and use 5 cores only.
If we use ponder on we have some more depth and 2-fold less games.
I want to play 1000 games within a month, not two.

[ouachita]

thx, I run ponder on with 16 cores at ~ 24 hrs/move, and was just curious about your thinking

Very good performance for correspondence chess
Complete information about pondering you could find on chesswiki

Pondering mode is doesn't matter in your case, when you use engines for infinite analysis mode AFAIK. It is not the same as engine vs. engine playing mode, when pondering is simply using the opponent's move time to consider likely opponent moves.
