## Single-Check

One check wins. No checkmate needed — just deliver a single check and the game is over. Every move is life or death.

### Setup

**Board:** Standard 8×8.

**Setup:** Standard chess starting position.

**FEN:** `rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1`

### Rules

All standard chess rules apply, except:
- The game ends immediately when a player delivers check.
- Checkmate is not required — any check wins, even if it could be blocked or evaded.
- Stalemate is still a draw.

### Win Condition

Deliver check to the opponent's King.

### Strategy

The game becomes about pure King safety. Pieces that can give check from a distance (Queen, Bishops, Rooks) are incredibly dangerous. Any discovered check possibility must be neutralised immediately. Development speed is everything — the first player to create a check threat usually wins. Knights are particularly dangerous because their checks cannot be blocked. Games are extremely short.
