Grail 1.0.1 - new version chess engine
Grail - UCI chess engine
Author: Jørgen Hanssen
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 1.0.1 what's new?
Improvements
Better at recognizing positions with insufficient mating material and avoids playing them for a win.
Puts more effort into evaluating positions with potential pawn promotions.
Improved time allocation for move-based time controls (e.g. 40/10).
The Move Overhead UCI option is now exposed (default: 20ms) to compensate for network or GUI latency.
Various search parameters have been refined through automated tuning.
Elo gain over 1.0.0
STC (10+0.1): +27.9 ± 5.3 Elo (10k games)
LTC (60+1.0): +19.5 Elo (500 games)
