Grail 3.0.0 - new version chess engine

Grail - UCI chess engine Author: Jørgen Hanssen  Rating CEDR=3454 After working on it for a while, I feel my hobby chess engine is finally ready for v1.0.0. Not cutting edge, but plays a solid game. Grail uses modern search techniques and evaluates positions using a simple NNUE trained on 500 million positions from self-play. Development continues in my spare time, and I plan to release updates with several missing features and improvements like threading, tablebase support, and pondering. But don't worry! Grail supports all standard UCI time controls and analysis modes, so it works seamlessly with your favorite GUI for matches and analysis. Grail - what's new? Long time no see! I’m happy to release Grail 3.0.0. This version adds support for Chess960 and Android builds along with an improved NNUE, faster/better search, and some bug fixes. New features Chess960 / Fischer Random: supported through the standard UCI_Chess960 option. Android: a new grail-arm64 binary is included...

Today, we are presenting a collection of 16 new chess engine versions. As you may have noticed, we’ve started changing the way we feature weaker or newly released engines. With the rapid rise of AI-assisted engine development, the sheer volume of new releases makes it impossible to give every single one its own standalone post. Naturally, this new approach does not apply to top-tier engines—such as those competing in the CEDR League (the top 64)—which will continue to receive dedicated coverage.
