## Popis

Human2Human Chess Duell provides a complete online chess game for two human players.

There is no AI – only the full chess rules.

Features:

 * Human vs human via a shared link (hash in the URL: ?chess_game=…)
 * Whoever creates the game plays White; the second visitor automatically becomes
   Black.
    Further visitors watch the game as spectators.
 * Players can choose their own name. For logged-in WordPress users the display
   
   name is pre-filled (and can be overridden).
 * Logged-in WordPress users (any role) may bypass the limit of simultaneous games.
 * Full chess rules: castling, en passant, pawn promotion,
    check/checkmate/stalemate,
   fifty-move rule, insufficient material.
 * Server-side rule validation: every move is validated on the server
    (custom PHP
   engine). Cheating via a manipulated browser is not possible.
 * Configurable in the backend: number of simultaneous games and the lifetime
    until
   automatic end (Settings > Human2Human Chess Duell).
 * A game ends only by checkmate, resignation or draw – or expires after the
    configured
   period of inactivity (default 14 days).
 * Optional chess clock when creating the game. Only the online time of the
    player
   to move is counted – if someone is offline, their clock pauses (no time spent
   overnight). On timeout the player loses.
 * Optional e-mail notification when it is your turn (pre-filled for logged-in
    
   users with a stored address). The address is used only for the notification and
   automatically deleted when the game ends – not stored permanently (technically
   visible in the server log).
 * Updates do not interrupt running games (backward-compatible data).
 * Synchronization via the WordPress REST API (polling, every 2 seconds).
 * No external dependencies (no CDN, no images) – Unicode chess pieces.
 * In-game private chat between the two players, a move list, an optional
    „show
   piece names“ tooltip helper, and a personal „continue on another device“ link(
   e.g. move from desktop to phone).

The plugin interface is in English and fully translatable. A complete German
 translation(
de_DE, incl. de_DE_formal) is bundled with the plugin.

## Instalace

 1. Upload the plugin ZIP under „Plugins > Add New > Upload Plugin“ and activate it.
 2. Insert the shortcode on a page or in a post:
 3. [chess_duell]
 4. Open the page, click „Start new game“ and send the displayed link to your opponent.

## Nejčastější dotazy

### Is an account required to play?

No. Guests can play without logging in. The link you share identifies the game.

### Can I continue a game on another device?

Yes. Each player can generate a personal „continue on another device“ link and
 
send it to themselves (for example from desktop to phone) to keep playing as the
same color.

### Is cheating possible?

No. Every move is validated server-side by a custom PHP chess engine; the server

computes the position (FEN), notation (SAN) and game end itself and is the single
source of truth. A manipulated client cannot force an illegal move.

## Přehled změn

#### 1.11.0

 * Internationalization: source strings are now English; a complete German translation(
   de_DE and de_DE_formal) is bundled.
 * All user-facing strings are now translatable, including the admin settings page,
   REST error messages and the e-mail notification (previously hard-coded in German).

#### 1.10.0

 * New: „Continue on another device“ – each player can create a personal link and
   send it to themselves (e.g. from desktop to phone) to keep playing as the same
   color. The token is adopted on opening and immediately removed from the URL.

#### 1.9.1

 * Fix: the board became too small in the new layout and the bottom row was cut 
   off. The board now sits large at the top, with the move list and chat side by
   side below it; the board always stays perfectly square.
 * Fix: in the narrow chat column the „Send“ button wrapped and the input field 
   was squeezed – input row corrected.

#### 1.9.0

 * The chat now sits directly to the right of the move list (instead of below it)
   for better visibility. On narrow screens they remain stacked.
 * New option on the game page: „Show piece names“ – hovering a piece with the mouse
   shows its name (e.g. „Queen (White)“, „King (Black)“). The setting is remembered
   per browser.

#### 1.8.0

 * New private chat between the two players (only the two players can read and write).

#### 1.7.0

 * New „My games“ switcher: players with several open games can switch within the
   same window without reloading (with a „your turn“ marker).
 * Games are associated with players: WP user ID for logged-in users and an anonymous
   guest browser ID. The backend overview shows the account (@login).

#### 1.6.0

 * Backend: overview of all running/stored games with the option to delete individual
   games (and all finished ones at once).
 * Backend: the limit bypass for logged-in users is now optionally on/off.

#### 1.5.7

 * The „it’s your turn“ e-mail now includes the last move played.

#### 1.5.1

 * The last move is highlighted: origin/target squares on the board and the entry
   in the move list.

#### 1.4.0

 * Optional chess clock (counts only online time, pauses on absence).
 * Optional „it’s your turn“ e-mail notification; the address is deleted when the
   game ends.
 * Backward compatible: running games survive the update unchanged.

#### 1.3.0

 * Logged-in WordPress users may bypass the games limit.
 * The display name of logged-in users is pre-filled as the player name (overridable).

#### 1.2.0

 * Server-side rule validation (custom PHP engine) – cheating no longer possible.
 * Backend settings for the number of simultaneous games and the lifetime.
 * Players can choose their own name.

#### 1.0.0

 * First version.
