Five-Check
An extended version of Three-Check. Deliver five checks to win. More room for strategic play while still rewarding aggressive checking sequences.
Five-Check — starting position
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, plus:
- Each player’s checks are counted (regardless of how the opponent responds — block, evade, or capture the checking piece).
- Reaching five checks wins the game immediately.
- Checkmate also wins (as normal).
- Stalemate is a draw.
Win Condition
Deliver checkmate OR deliver five checks total.
Strategy
Similar to Three-Check but with more breathing room. The higher threshold means you can’t win by brute-force sacrificing into checks — you need sustained pressure. Pieces that deliver repeated checks (especially Queen and Rooks on open files) are strong. Trading your opponent’s checking pieces while preserving your own is a key strategic layer beyond normal chess.
