There is information about it.

people played tournament games with it.
It won Mchess8 in your tournament.

It is leading an engine-engine tournament under Fritz6

see http://www.netcologne.de/~nc-schwaran2

I can tell you only that the evaluation is different from Junior5.

one of the changes is the fact that the value of the pawn was reduced.

It cause positive and negative results.

Example to the positive result is that Junior5.9(and I guess that also Junior6)
can avoid the famous Qxg7 mistake of zunzwang against a human and prefers after
some minutes another queen move.

Example to the negative result is that Junior6 cannot find the famous sacrifice
of Junior against nimzo(I asked someone who has Junior6 about it).


>has anyone until now seen information about "the new" nimzo

Yes.
I remember that Marcus Kästner posted that Nimzo7.32 did 7:7 against
chesstiger12E at tournament time control.

I think the hardware was celeron550.

on the other hand I know that nimzo7.32 lost against nimzo99 in an engine-engine
tournament under fritz6

I saw Rebel century-Shredder4 3.5:.5(time control was 30 minutes/game)
games were played manually.
