This is a simplified version of chess, played on a 6×6 (rather than 8×8) board without bishops. Pawns can move only one space forward, and there is consequently no en passant capture. In this modified version, castling is allowed, along with pawn promotion to a previously lost piece. There is no automation in this Demonstration. Players must make moves manually, by dragging a piece. Captured pieces must be dragged to the gray sideline. Just as in a noncomputerized board game, players are responsible for making only legal moves and declaring "king in check", "checkmate", or "stalemate" when appropriate. Two players can use separate computers connected on a Wi-Fi network.
