Hi Jeroen,

Ooops you got me! Hmm, let's see. It's late in the evening, I'm tired, I am
going to bed now!
Okay, I will ask Chrilly and tell you as soon as possible ;-)
Sorry!

Here are my settings I use for Varguz on ICC:
PVal=110
NVal=420
BVal=425
RVal=685
QVal=1280

Remark: These are values for the Nimzo 7.32 Winboard engine. I increased QVal
from 1240 to 1280 because otherwise Nimzo likes to exchange his queen for the
opponents rook + bishop + pawn which is definitely poor (at least for Nimzo) but
keeping R + R > Q.

Greetings
Alex
