I can attest that Harmon plays a really fine brand of chess for a NNUE net. I'll post one of its amazing wins when I have time.
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.
