**Zeal** is a UCI-compliant chess engine written in Rust. ## Features
- **Board**: 8 bitboards + 8×8 mailbox
- **Search**: Negamax Alpha-Beta, Iterative Deepening, Aspiration Windows, PVS, Quiescence, Check Extensions, Transposition Table
- **Pruning**: Null Move, Reverse Futility, Late Move Reductions
- **Move Ordering**: TT move, MVV-LVA, killers, history heuristic
- **Evaluation**: PeSTO piece-square tables with tapered eval
- **Time Management**: hybrid soft/hard timeout bounds
## Usage
Zeal speaks [UCI](https://www.chessprogramming.org/UCI), so it isn't meant to be played from the terminal directly. Point any UCI-compatible GUI like [Cute Chess](https://cutechess.com) at the compiled binary and play from there.
## Strength
No official rating yet. Estimated around **2300 Elo**, based on self-play SPRT roughly on par with [Stash](https://gitlab.com/mhouppin/stash-bot) v17 (CCRL Blitz 2298).
