On which engine CyberNezh based?
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. :D



Not to rain too much on the CyberNezh Parade but of course needed to take a bit deeper look...has CyberNezh played some match games vs Open Tal? What was the result?... Thx AR :) :wink:

400-500 Elo difference in strength. :)

OpenTal was designed (by me) for patzers (like me) to train against, while Nezh seems around 3000 Elo. :D

I'm just an average blitz player, I had not much chances against an engine... I watched live Nezh against another bot, and was sent a challenge. I had no illusion about my chances, but I accepted by curiosity.

Oh ok. I'm just basing my estimation on game results against other engines, which Carl has previously posted.

Meanwhile Open Tal shows fantastic promise in both Shredder and Banksia Gui's and limited progress in Fritz (Engine name and ID in wrong position for recognition by GUI..from the beginning)....Next possible test Chess Tal vs Open Tal Match (couple of games) "Let Just see shall we"....should be fascinating... :) :wink:

Brendan is basically right. I estimate it to be somewhere around 2800-2900 Elo CCRL, but things can vary from game to game due to the intrinsic volatility of its risky style, or based on time control.

A new blitz game (5 0) played today vs a strong human:



A typical game with Black, where things look a little quiet, but under the surface lurks great danger. The position is built up slowly, but once ready, the axe falls with great ferocity. Of course, not everything may be entirely sound, especially at faster time controls, but enough to dazzle even a strong opponent.

Very telling is move 10, where White castles, while Black responds with Kf8!, keeping the Rook where it belongs on the semi-open h-file. This proved decisive. Pretty basic you might say, but a 2300+ human opponent walked right into it.

ShashChess 5.0 (last stylistic ShashChess) finds Bh6 instantly, thinks capturing the sacrificed Bishop is a mistake:

Yes, other engines may find moves like Bh6 easily, but the more relevant question is 'can other engines reach those positions in the first place'? This is the same distinction that great attacker Rudolf Spielmann made between himself and the legendary Alekhine, where he acknowledged that while he could find the same brilliant shots as Alekhine, reaching the same positions was an entirely another level of skill.

Here's a fresh win vs a master:
