data extracted from FICS on June 9, 2021 blitz standard konozrout 2040 2246 (phalanx xxv 2000 nps + ponder) pikozrout 2101 2230 (phalanx xxv 8000 nps + ponder) There is no correlation between the blitz and standard rating for konozrout and pikozrout this is obviously because ponder compensates the nps difference for standard games my suggestion is that to create such a correlation, ponder should be partial (50% or 30%). a new option would weaken the engine on the opponent's turn, keeping -n nps for...

obviously the more seconds per move, the more nodes. I'm still interested in pikozrout configuration options as well as which opening book you use.
-
Hello, question 1: can you publish the fine tuning of pikozrout in addition to -n 8000 question 2: how is it possible that with the same nps limit the standard rating is higher, if time does not affect? Thx
