# Entertain Area · HyBBX

Optional **Main / standalone Main** feature plugin. Chess is a **fixed** part of
Entertain (no separate `chess=` INI key). AmigaOS builds force the plugin **OFF**.

## Enable

| Layer | Setting |
|-------|---------|
| Build | `-DHYBBX_PLUGIN_ENTERTAIN=ON` (default on POSIX; forced off on AmigaOS) |
| INI | **`[entertain] enabled=yes`** (not under `[networks]`) |
| Role | `hybbxd` Main or standalone Main only |

```ini
[entertain]
enabled = yes
```

Legacy `[networks] entertain=yes` is still read with a warning — prefer `[entertain]`.

Log: `[entertain] enabled=yes …` then `[entertain] plugin loaded — chess_max_games=…`

When Entertain is off, `/chess` stays **Unknown command** (by design).

## Chess

| Command | Action |
|---------|--------|
| `/chess help` | Command list |
| `/chess new` | Create game (White) |
| `/chess join [id]` | Join as Black |
| `/chess watch [id]` | Spectate |
| `/chess move e2 e4` | Move (`/mv e2 e4` or `/mv e2e4`) |
| `/chess resign` / `/chess draw` | Resign / offer-accept draw |
| `/chess list` / `/chess board` / `/chess clear` | List / show / free finished slots |
| `/play …` | Alias for `/chess` |
| `/proxychess …` | **Stub** — future chess via mains_proxy mesh |

Limits: no castling, no en passant; pawn promotes to Q/R/B/N. Compact ASCII board.
