Thanks, that's interesting. This net's posted date is Dec 2, 2020, so it's not that old - newer than the default SF net, in fact(!)

Yes.

Hi Master Om,
I'm curious, which net are you using with the Nodchip SF of 20/07/19?
I find it intriguing that the older nets could still be better at analysis.
Thanks!

Hi Frank.

Have someone check if it is available after this update FatFritz 2
You must buy Fat Fritz 2 separately.
If u have the chessbase update 23, Unzip it with 7-Zip. U will have fatFritz2 and its NN also.

Almost all engines i had specially SF NNUE. Although I use IDeA in aquarium i didnt find any way to penetrate the position.
Try the night nurse or dark horse nets. Though not yet as strong as the SF nets, they definitely have a different opinion on many positions.
Sure....
