Without reference to this particular position. (I'm using all my memory in about
15 Navigator boxes)

The line
Nxg3
-9.25 depth 13/51 14:43:27 30094298kN

Fritz is saying to me:
"the last time I decided on Nxg3, which I will announce at ply 13.01, I made a
reasonably substantial change in the score to make it -9.25.  Because of this
change I am now looking again more deeply at this move.  Sometime in the next 15
or so hours I will announce 13.01 Nxg3 plus extension, at a score approximating
-9.25"

Fritz is saying this in a German accent with humour, just like he says "What,
you are taking back Again?"

cheers,
