## What is Border Chess?

Border Chess is chess with room to breathe.

The board is 10×10: standard FIDE chess on the inner 8×8, plus one empty square on every side. Kings, queens, and edge pawns can use the border for extra maneuvering — same rules you know, with new tactical possibilities.

PLAY VS BOT
Challenge Fairy-Stockfish, tuned for the border board. Choose your difficulty and improve your game against a strong computer opponent.

PLAY WITH FRIEND
Pass-and-play on one iPhone. The board automatically flips each turn so both players see the game from their side.

BUILT FOR CHESS PLAYERS
• Standard rules: castling, en passant, promotion, check, checkmate, stalemate, 50-move rule
• Legal move hints, last-move highlight, and check highlight
• Clean, modern board inspired by chess.com
• Portrait mode, optimized for iPhone
