Setup

Board: Standard 8×8.

Setup: Standard chess setup.

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

Rules

Identical to standard chess except:

  • Pawns may advance two squares from ANY rank (not just their starting rank), provided both squares are empty.
  • En passant applies whenever a pawn double-moves past an enemy pawn, regardless of which rank it starts from.
  • All other rules unchanged.

Win Condition

Checkmate.

Strategy

Passed pawns become much more dangerous because they can sprint two squares at a time. Pawn endgames are sharply different — a pawn on the 5th rank can reach promotion in two moves instead of three. Blockading passed pawns is more difficult. Connected pawns rolling forward together are extremely powerful.
