I set up a version of Nezh as a BOT at lichess. If you ever wished go up against Nezhmetdinov, Tal or Alekhine, now you can, but all rolled up into one!
Still working out some kinks, but it's running fine. For now it's playing without a book. Rapid or faster time controls are available.
Enjoy!

My guess Rodent, or Benjamin...

Well, Rodent has been a source of inspiration, conceptually. I would look at Nezh as being rather based on great unsung attacking heroes from the past such Rashid Nezhmetdinov and Nicolas Rossolimo, with a nod to Tal and Alekhine's genius as well.
Its strength is substantial and it can take care of any opposition below 2800 Elo, be it human or engine. One of the goals was to reach a level of strength equal to or slightly stronger than the best human GMs. Even more important than strength is the swashbuckling, daring style, of course. Nezh is fearless and can take enormous risks in pursuit of winning. There's no 'draw death' to worry about.

Hats off to Alayan for not being afraid to take on Nezh. The lightning bolt is 14. Bh6!!, a move that leaves a lasting impression.

Where can one get the source code for this engine? Or a Linux binary?

I see. Who is the author of the program? I've never heard of this engine before.

I'm only the tester. The author wants to keep a low profile.

ShashChess 5.0 (last stylistic ShashChess) finds Bh6 instantly, thinks capturing the sacrificed Bishop is a mistake:14.Bh6 gxh6 15.dxc5 Be7 16.Ne5 Nd5 17.Qh5 Rf8 18.Nxc6 bxc6 19.Nd6+ Bxd6 20.cxd6 Rg8 21.Qxh6 Bd7 22.Qxh7 O-O-O 23.Qxf7 Kb7 24.Rac1 c5 25.h4 Kb8 (8.055.774) 2787gxh6 15.dxc5 Be7 16.Ne5 Nd5 17.Qh5 Rf8 18.Nxc6 bxc6 19.Nd6+ Bxd6 20.cxd6 Kd7 21.Qxh6 Bb7 22.Rac1 Kxd6 23.Qxh7 Kd7 24.h4 Rae8 25.h5 Kc8 26.Qg7 Rd8 27.Red1 (51.216.627) 2735Be7 (62.162.781) 2743
