Nudge Chess

Chess with one extra kind of turn

Nudge Chess keeps normal pieces, legal moves, check, checkmate, castling, and promotion. On any turn, however, the player may use a lit handle around the board to push an eligible rank or file one square instead of moving a single piece.

When a nudge is legal

White pushes files upward from rank 1 or pushes ranks 1 through 4 from either side. Black pushes files downward from rank 8 or pushes ranks 5 through 8 from either side.

The edge square must contain a piece and a completely full eight-square line cannot move. A nudge cannot place the mover's king in check, but it may block a check, carry the king to safety, or push a pawn onto its promotion rank.

Local and computer matches

Two players can share one screen, with an option to turn the board toward the side to move. Computer play offers Easy, Medium, and Hard levels and lets the player choose a color.

Undo and flip controls make experimentation painless, while the move list distinguishes ordinary chess notation from nudges. Keyboard shortcuts U, F, and Escape cover undo, board flip, and cancel.

Guide

Choose: Play two players on one screen or switch the opponent to Easy, Medium, or Hard computer play
Move: Select and move pieces under standard chess rules, including check, checkmate, castling, and promotion
Nudge: Use a lit yellow handle to push an occupied rank or file one square from your own edge
Plan: A nudge consumes the entire turn and cannot move your own king into check, but it may block check or carry the king out
Review: Use U to undo, F to flip the board, and the move list to track both normal moves and nudges

Creator's description

From the starting position, the valid a1 file handle moved the white rook and pawn one square upward. The move list recorded a1, the status changed to Black to move, and the game explained that no piece is captured by a nudge.
