--- ENGLISH -------------------------------------------------------

Chess game for all classic Amiga models (A500-A4000). Compiled for
68000 so it runs on every Amiga with Kickstart 2.0 or higher.

This project is proof that Claude AI (Anthropic) handles Amiga C
programming surprisingly well. Using AI prompts, it is possible to
create fully featured Amiga games from scratch - complete with a
chess engine, GadTools menus, PGN support and Workbench icons.
The Amiga community finally has a new chess game in 2026!

Future versions are planned for faster processors (68060, PPC)
and graphics cards. The engine will grow stronger with each release.

Features:
- Negamax alpha-beta engine with iterative deepening
- Quiescence search, aspiration windows
- Transposition table (Zobrist hashing, optional)
- Move ordering: MVV-LVA, SEE, killer moves, history heuristic
- Piece-square tables (middlegame + endgame)
- Opening book with 8 popular openings (optional)
- 5 difficulty levels (1-3 suitable for 68000, 4-5 for 68060)
- Time limits per move: none / 30s / 60s / 90s
- Player vs AI / Player vs Player / AI vs AI modes
- PGN save/load with ASL file requester
- Move history, Undo/Redo
- Game timer with pause
- Settings saved to PROGDIR:chess.prefs
- GadTools menu, English interface

Estimated strength:
- Level 3, TT off: ~1200 ELO
- Level 3, TT on:  ~1400 ELO
- Level 5, TT on:  ~1550 ELO (68060 recommended)

Installation: Copy Chees_AI to any directory and run.
Stack: 32768 bytes recommended.
