By "No name" I meant the candidates at the very bottom of the list.

cesso-a chess engine of Swiss origin (third from the queue) has a NNUE-based evaluation, modern search techniques,....sometimes it plays brilliantly (vs.Endspiel-Hedgehog-Erinn-Ember & co)....it is also in development. This is how interesting engines appear. Clones prefer the short way. And history quickly forgets them....

Of course, I mean no offense. Incidentally, I fixed several bugs in my engine thanks to battles with Ekagine, Cesso, Rustic alpha 1, 2, 3, and TSCP. That was before my contributor created the adaptive ELO rating system. A huge thank you to them.

[DreamerExx]

By the way, I'd like to share that Ember 0.9.2 (the old version), which I submitted to CCRL a little over a week ago, was rated at 1915 elo in the CCRL blitz. Before Ember 0.9.4, the engine had been rewritten using bitboards and a bunch of bugs had been fixed. The preliminary result for v0.9.4 is around 2200 elo. I've already submitted a new version to CCRL.

After this morning I compiled and introduced into my tournament the most powerful engine written in Rust-Reckless (code 09.06.2026), this evening I compiled and introduced into my tournament the 22nd engine. One with HCE evaluation, but very powerful-around 3300 Elo points!!! An engine ignored by......connoisseurs!!! The engine logo reproduces the Finnish atmosphere with images from my Iași - on the left the University, on the right the Palace of Culture (former princely palace of Moldova).
