I can tell you CyberNezh has gotten many stylish wins against engines rated below 3000 CCRL (a few were posted here in this forum), while sticking with its trademark speculative and dubious sacs. Its strength is about 2800-2900, just about the same as the human world champ, or a little better. Nezh handles flank attacks and closed positions quite well, and can mop things up in the endgame, if necessary. Weaker engines routinely underestimate Nezh's sacs/attacks.
Translating this kind of play into a net remains an open challenge. Net-based engines are generally risk-averse, valuing safety a little too much, and playing 'not to lose'.
You should try the Harmon NNUE, my favorite of all the nets I’ve trained. It is trained over 1 million human FIDE 2300+ games. It’s 80% WDL and 20% primitive material qsearch. It’s 400 elo or so weaker than SF13 running on the same binary. Will run on any engine that supports the original format NNUE.
Let me know how it does vs CyberNezh.

Well aware of Harmon.
I acknowledged your nets in a previous post in this thread. A few months back I posted an amazing Harmon win:
http://talkchess.com/forum3/viewtopic.p ... on#p887654
Something got mangled in the pgn, so I'll repost the whole thing below. [Note: Harmon's much stronger than the heavy risk-taking CyberNezh, because its overall play is much sounder. Nezh is very fond of dubious sacs.]
-------------------
To illustrate what Harmon's capable of, I'm posting an entertaining and adventurous game. First, here's an amusing diagram from this game:
[d]4N2r/pp6/6k1/2p1N3/NP3p2/2K3p1/3B2qr/RR6 b - - 0 34
Not even the third knight (!) could save Senpai here. An exceedingly impressive attacking effort from the Black side of an opening (the Czech Benoni) that engines 'normally' don't like. Fabien Letouzey's Senapi 2.0 is no slouch, having an Elo of over 3100 CCRL 40/15 running on 4 cores. Harmon ends up owning the h-file with the white king hard pressed to find safe haven.
