Racing Kings

Racing Kings

No checks allowed. Race your King to rank 8. A pure positional race with no violence.

Setup

Board: Standard 8×8.

Setup: All pieces start on ranks 1–2 in a specific non-standard arrangement. No pawns.

FEN: 8/8/8/8/8/8/krbnNBRK/qrbnNBRQ w - - 0 1

Rules

Pieces move and capture exactly as in standard chess. There are no pawns, no castling, and no promotion.

The no-check rule. No move may result in either King standing in check. This has two components:

1. You may not give check. No move may place the opponent’s King under attack. This is the variant’s distinctive restriction and has no equivalent in standard chess.
2. You may not move into check. As in standard chess, no move may leave your own King under attack, and the King may not move to a square attacked by an enemy piece.

Because both components apply to every move, check never occurs in a legal game. There is consequently no checkmate, and no concept of escaping check.

A King cannot advance to a rank-8 square that is defended by an enemy piece, so the eighth rank can be contested by defending its squares rather than by blocking the path.

Win Condition

A player wins by moving their King to the eighth rank, subject to the equalising rule below.

The equalising rule. Black moves second and is compensated as follows:

• If White’s King reaches the eighth rank, Black immediately takes one further turn. If on that turn Black legally moves their King to the eighth rank, the game is a draw. If Black does not or cannot, White wins.
• If Black’s King reaches the eighth rank first, Black wins immediately. White has no equalising move.

The rule is deliberately asymmetric. It exists solely to offset White’s first-move advantage.

When Black cannot equalise. Black’s equalising move is an ordinary legal move and is subject to every normal restriction. Black therefore fails to equalise, and White wins, if:

• No rank-8 square is reachable by Black’s King in one move.
• Every reachable rank-8 square is attacked by a White piece, since the King may not move into check.
• Moving the King to rank 8 would give check to White’s King (e.g. by discovery), since giving check is illegal.

Stalemate. A player with no legal move, who by definition cannot be in check, draws. Stalemate is a draw, as in standard chess.

Strategy

Block your opponent’s King path while clearing your own. Rooks and Queens control files; Bishops control diagonals. The constraint against giving check makes many “obvious” blocking moves illegal.
