1D Chess

I was recently watching a YouTube video about a one-dimensional chess variant and thought it would be fun to implement. You can check out the completed code here.

It turns out there are a number of different 1D chess variants, but in this specific one the board is 8 squares long and each side only has a king, knight, and rook. Piece movement is similar to regular chess except for the knight, which can move two squares in either direction (and hop over pieces). Capturing pieces, stalemate, check, and checkmate all work the same as in normal chess.

Below you can play as the white pieces against an AI I programmed. Click on a piece and grey dots will appear to show that piece's legal moves. Clicking on a square with a grey dot will move the piece to that square.

It turns out that white has a forced win from the very beginning - can you find it? Be careful not to concede a stalemate!
