The engine is tuned for aggresive play instead of normal engine like play, it'll be fun playing against it :p

Roughly how strong is it?
Is it an AI assisted engine?
Have you given credit where it's due?

I benchmarked it against Stockfish levels, they are a bit unreliable but it was around 2000 elo range.Graham Banks wrote: ↑Fri Aug 21, 2026 7:46 am Roughly how strong is it?

yeah AI assistance was used to develop parts of the engine.
The whole source code is mine without usage of any books or nnue so there's no credit to give tbh.

I'll make Gabor aware of your engine. He does the blitz testing.eren4710 wrote: ↑Fri Aug 21, 2026 8:44 amIs it accepted for CCRL??

I'll hold off on 40/15 testing until your engine reachers 2550+.

So you invented "hand-crafted evaluation (HCE), magic/PEXT-based sliding attacks, and a tapered midgame/endgame evaluation" all by yourself?eren4710 wrote: ↑Fri Aug 21, 2026 8:38 amyeah AI assistance was used to develop parts of the engine.Graham Banks wrote: ↑Fri Aug 21, 2026 7:46 am Roughly how strong is it?

Re: Ravager 1.0 Chess Engine
Yeah, the engine follows an aggresive playing style rather than normal engines with many additions adding to the aggresivenessGabor Szots wrote: ↑Fri Aug 21, 2026 9:31 amSo you invented "hand-crafted evaluation (HCE), magic/PEXT-based sliding attacks, and a tapered midgame/endgame evaluation" all by yourself?eren4710 wrote: ↑Fri Aug 21, 2026 8:38 amyeah AI assistance was used to develop parts of the engine.Graham Banks wrote: ↑Fri Aug 21, 2026 7:46 am Roughly how strong is it?
